  • Comparative economic profitability of MV T. Aus rice (Oriza sativa L.)
           Cultivation under different crop management practices in some selected
           areas of Chuadanga district

    • Authors: MA Quayum, MA Salam
      Abstract: A study was conducted to estimate the productivity gap in MV T.Aus rice between potential farm and actual farm as well as examine the factors responsible for MV T.Aus rice yield gaps in Chuadanga. In the Aus season, 80 demonstration plots managed by Department of Agriculture Extension and 80 farmers’ managed plots were selected from four villages of Chuadanga sadar upazila. Data were collected in two phases using structured questionnaire. Both tabular and statistical techniques were employed for analyzing the data. The analysis has further been extended to estimate the contribution of individual technical factors to the yield and the input-output relations. The average yield of MV Aus rice were 2.84 t/ha and 3.31 t/ha in the farmers’ plots and demonstration plots, respectively, indicating 17% yield gain in the demonstration plots. The production cost per hectare on full cost and cash cost basis were 16 and 1% higher, respectively, in the demonstration plots than that in the farmers’ plots. But the unit cost of production on full cost and cash cost basis were lower 0.60 and 15%, respectively, in the demonstration plots than that in the farmers’ plots. The benefit cost ratio (BCR) was also higher on full cost and cash cost basis in the demonstration plots compared to farmers’ plot. Analysis further indicated that there is ample scope of increasing modern Aus yield by 0.29 t/ha through adopting appropriate variety, timely sowing and proper irrigation as well as weeding at the farm level.

  • Growth and yield of wheat (Triticum aestivum) under deficit irrigation

    • Authors: PK Sarkar, MSU Talukder, SK Biswas, A Khatun
      Abstract: Timing and the extent of water deficit were studied in a field experiment on wheat (cv. Shatabdi) for three consecutive years from 2003-04 through 2005-06 at Jamalpur area. The effects of number and timing of irrigation application on yields were investigated under variable soil moisture condition in the root zone of different treatments. Eight deficit irrigations, including one no stress and one rainfed treatments were selected to subject the crop to various degrees of soil water deficit at different stages of crop growth. Measured amount of irrigation water was applied as per schedule prescribed for a particular treatment. Grain yield (GY), biomass, harvest index (HI), and water productivity (WP) were reasonably affected by deficit irrigation. Other yield contributing parameters like 1000-grain weight, grains/spike and spike, length were also affected by different levels of deficit irrigation. During grain formation stage, water deficit did not affect the grain yield but saved water significantly. Such water deficit treatments also shortened the grain maturation period. Differences in grain and straw yield among the stressed and no stress treatments are comparatively small, and statistically insignificant in some cases. The highest water productivity (2.02 kg/m3) was observed in treatment which was irrigated only once at crown root initiation stage (T2) although the yield was comparatively low. The CRI (crown root initiation) stage was found the most sensitive to water stress. Water stress at vegetative stage also reduced the yield considerably.

  • Influence of seed rates and levels of NPK fertilizers on dry matter
           accumulations and yield performance of foxtail millet (Setaria italica L.
           Beauv.)

    • Authors: MS Hasan, MH Rashid, QA Rahman, MH Al-Mamun
      Abstract: A study was carried out in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Old Brahmaputra Flood Plains Soil (AEZ-9) during December 2001 to April 2002 to find out the effect of seed rates and NPK levels on dry matter accumulation and grain yield of foxtail millet (Setaria italica L. Beauv.). Four seed rates viz., 8,10,12, and 14 kg/ha and five levels of NPK fertilizers viz., N0P0K0, N10P8K5, N20P16K10, N30P24K15, and N40P32K20 were included in a split plot design with three replications. Dry matter accumulation pattern was determined by harvesting 10 plants randomly at 30, 60, 80, and 102 DAS (days after swing). The yield and yield contributing characters of foxtail millet were influenced by seed rates and NPK levels except tillers per plant and 1000-grain weight significantly. Generally its production rate was 0.86 t/ha when it was grown in char lands in sandy loam soils, the highest grain yield (1.62 t/ha) was produced by 10 kg seeds/ha, which was identical with 12 kg seeds/ha. In case of NPK levels, the treatment was N30P24K10. In case of interaction, the treatment combination 12 kg seeds/ha and N30P24K15 produced the highest grain yield (1.77 t/ha. In case of interaction, the treatment combination 12 kg seeds/ha and N,sub>30P24K15/ha gave the highest grain yield.

  • Variability, correlation and path analysis in lablab bean (Lablab
           purpureus L.)

    • Authors: M Salim, S Hossain, S Alam, JA Rashid, S Islam
      Abstract: The results of the study carried out during 2009-2010 with lablab bean (Lablab purpureus) are presented in this paper. Data were recorded from all experimental plants on the following characters as number of pods/plant, pod yield/plant (g), number of seeds/pod, number of seeds/plant; seed yield/plant (g), Range, mean, genetic parameter, correlation co-efficient and path coefficient were studied. High heritability coupled with high expected genetic advance in percentage of mean were observed for most of the characters. The coefficients of correlation showed that seed yield/plant was positively and significantly correlated with days to first flowering, days to 50% flowering, days to first pod setting, number of pods/plant, pod yield/plant and seeds/pod, number of seeds/plant, and seed yield. Path coefficient analysis showed that days to first flowering, days to 50% flowering, number of pods/plant, 20 pod weight (g), pod yield/plant, pod length, number of seeds/pod, number of seeds/plant, 100-seed weight influenced seed yield/plant directly in positive direction. Among the characters, number of seeds/plant had high positive correlation with seed yield/plant. Days to first pod setting exhibited negative direct effects on seed yield. From this result, it can be concluded that days to first flowering, days to 50% flowering, number of pods/plant, pod yield/plant, number of seeds/pod, number of seeds/plant, 100-seed weight are the most important yield contributing characters as they influenced pod yield and seed yield directly in positive direction.

  • Effect of planting time and nitrogen application on the yield and seed
           quality of T. Aman rice (Oryza sativa L.)

    • Authors: ASMI Hussain, MM Hoque, MN Huda, D Hossain, M Shahjahan
      Abstract: A field experiment was conducted at the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during June 2006 to December 2007 to find out the effect of planting time and nitrogen fertilization on the yield and seed quality of T. Aman rice. BR11 ( Mukta) was transplanted at different dates from 5 July to 19 August at 15 days interval. The rates of N used in the experiment were 80, 100, 120, and 140 kg N/ha,. Plant height, number of tillers/hill, grain yield, and yield components parameters varied significantly due to transplanting of rice at variable dates. The optimum time of planting was found to be 4 August compared to other dates of transplanting. Result indicates that this variety planted in optimum time gave higher yield with high quality of rice seed. In comparison to early and late planting, earlier planting of the variety was better as the late planted crops were severely affected by adverse environmental condition during reproductive phase. The poor grain yield in early or late planting was due to higher percentage of spikelet sterility. The varieties responded positively with increment of N levels upto 120 kg N/ha. The higher number of panicles/m2, lower percentage of unfilled grain, and heavier individual grain contributed to increase grain yield of this verity. It is, therefore, suggested to transplant BR11 rice in the first week of August in Aman season. The application of N of 100 -120 kg/ha with three splits is optimum for achieving higher grain yield and better quality of rice seed.

  • Efficacy of fungicides and organic oils to control powdery mildew disease
           of jujube (Ziziphus mauritiana Lam.)

    • Authors: MZ Hoque, AM Akanda, MIH Mian, MKA Bhuiyan
      Abstract: Powdery mildew (Oidium erysiphoides f.sp. ziziphi) is the major disease of Indian jujube (Ziziphus mauritiana) in Bangladesh. An experiment was conducted to test the efficacy of six fungicides, two organic oils, and a detergent against the disease. Tested fungicides were Tilt (Propiconazole) @ 0.05%, Folicur (Hexaconazole) @ 0.1%, Bavistin DF (Carbandazim) @ 0.2%, Dithane M-45 (Mancozeb) @ 0.3%, Thiovit 80 WG (Sulpher) @ 0.3%, and Cupravit (Copper) @ 0.3%, the oils were Mustard oil @ 0.5% and Neem oil 0.5%, and the Detergent (Trix) @ 0.5%. The materials were applied as foliar spray for seven times at an interval of 15 days. All of the fungicides and two oils gave significant decrease in severity of powdery mildew and increased fruit yield of Indian jujube irrespective of varieties, locations and over times. Among the treatments, Folicur, Tilt, Thiovit, and Dithane M-45 sprays were found effective than others. The severity index values on two jujube varieties were 3.89-4.50 at Mowna and 4.00-4.53 at Ishurdi in control treatment. The severity indices were reduced to 1.45-1.96 at Mowna and 1.33-2.07 at Ishurdi due to application of Tilt, Folicur, Thiovit, and Dithane M-45, which gave increase in fruit yield over control by 68.88, 63.69, 63.04, and 54.63% in Apple Kul and 83.25, 77.87, 77.39, and 70.36% in BAU Kul, respectively. Most of the treatments were able to reduce number of spotted fruits. The best effective fungicide was found to be Tilt followed by Folicur and Thiovit in reducing disease severity of powdery mildew as well as other fruit diseases like fruit spot and fruit rot and increase fruit yield of Indian jujube. Therefore, Tilt/Folicur may be recommended for jujube growers to control the powdery mildew disease in commercial orchard.

  • Potato (Solanum tuberosum L.) variety development through hybridization: a
           new era in Bangladesh

    • Authors: BC Kundu, MS Islam, MA Kawochar, MH Rashid
      Abstract: Systematic research on potato variety development has been in practice in Bangladesh since 1960, but until 2012, not a single variety was developed in this country through conventional breeding method, mainly due to the short day climatic factors which are not congenial for potato plants to flower. Due to the diversified efforts, TCRC scientists were able to make a breakthrough to overcome the climatic barriers. Flowering was induced in HYV potatoes and produce berries in the year 2000. After hybridization and continuous selection, five hybrid clones were placed in a RYT in 2010-11 from a batch of 502 kg F1 seedling tubers produced from 45 gram hybrid seeds of 2001-02. Based on the performances of SYT, AYT, RYT and on-farm trials, three varieties were released by the NSB in 2012 as BARI Alu-35, BARI Alu-36, and BARI Alu-37. Their genotype numbers are 4.5W, 4.26R, and 4.40, their mean yields were 38.36, 33.82, and 34.88 t/ha in AYT, 44.01, 41.84, and 40.58 t/ha in RYT, and 38.87, 38.52, and 37.53 t/ha in on-farm trials, respectively.

           Brassica rapa L.

    • Authors: MH Khan, SR Bhuiyan, MH Rashid, S Ghosh, SK Paul
      Abstract: The experiment was carried out with 32 genotypes of Brassica rapa including two commercially cultivated varieties as checks to study their inter-genotypic variability, heritability, GCV, PCV, genetic advance, and CV percent considering 10 morphological characters at the experimental farm of SAU, Dhaka during November 2009 to February 2010. Significant variation was observed among the genotypes for all the characters studied except thousand seed weight. High GCV and PCV values were observed for number of secondary branches/plant. High heritability values along with low genetic advance in percentage of mean were obtained for 1000-seed weight, number of secondary branches/plant, seeds/siliquae, and siliquae length. Highly significant positive association of seed yield per plant was observed with number of primary branches/plant, number of secondary branches/plant and number of siliquae/plant. Considering variability among the genotypes, heritability, genetic advance, percent co-efficient of variance, and field performances, the genotypes G-15, G-19, G-1, G-3, G-4, G-10, G-18, G21, and G-24 were found suitable for future breeding programme.

  • Assessment of soil carbon stock of some selected agroecological zones of
           Bangladesh

    • Authors: PK Saha, MS Rahman, M Khatun, ATMS Hossain, MA Saleque
      Abstract: The present investigation assessed the soil organic carbon (SOC) stocks of four AEZs in Bangladesh which included AEZ 1 (Old Himalayan Piedmont Plain), AEZ 3 (Tista Meander Floodplain), AEZ 4 (Karatoya-Bangali Floodplain), and AEZ 9 (Old Brahmaputra Floodplain). Three land types – high land (HL), medium high and (MHL) and low and (LL) – were considered in the SOC assessment. The SOC stock was estimated by multiplying SOC (%) with bulk density (g/cc) and soil depth (cm). Across the AEZs and land types, the SOC (%) decreased with the increase in soil depth. The SOC (%) was the highest in the low land and the lowest in the high land over the AEZs. The soil bulk density in every AEZ increased with soil depth. Bulk density of soil for medium high and varied from 1.26 g/cc to 1.67 g/cc, for high and from 1.33 g/cc to 1.55 g/cc, and for low land it was 1.13 g/cc to 1.44 g/cc. The SOC stock at 0-20 cm depth was higher (14.19-4.67 t/ha) in low land followed by medium high land (8.25-4.58 t/ha) and high land (6.46-3.39 t/ha) for all AEZs. Among the four AEZs, the highest SOC stock was found in AEZ 1 irrespective of land types.

  • Yield performance of oyster mushroom (Pleurotus ostreatus) on different
           substrates

    • Authors: D Das, M Kadiruzzaman, SK Adhikary, MY Kabir, M Akhtaruzzaman
      Abstract: An experiment was conducted at Mushroom Lab of Horticulture Centre under Department of Agricultural Extension (DAE), Khairtala, Jessore to determine the performance of different substrates on the yield of oyster mushroom (Pleurotus ostreatus). Sugarcane bagasse, sawdust, and coconut coir individually and their combinations were used as substrates. The experiment was laid out in Completely Randomized Design (CRD) with five replications. Data were taken from 1st and 2nd flush of different growth and yield attributes of mushroom. The maximum number of effective fruiting bodies was obtained from sawdust (40) and the lowest number (31.6) from combination of sawdust and coconut coir (1:1). In the 1st flush, the maximum weight of individual fruiting body was observed in coconut coir and minimum in sawdust. The highest biological (186.06 g) and economic yield (180.64 g) were obtained from coconut coir and the lowest from sugarcane bagasse. The maximum and minimum harvest index was found in 1st flush at coconut coir and combination of sawdust and sugarcane bagasse (1:1), respectively. Most yield attributes were found higher in coconut coir. Economic yield was positively correlated to number of effective fruiting bodies, pileus diameter, and biological yield.

  • Character association and path co-efficient analysis in Brassica rapa L.

    • Authors: MH Khan, SR Bhuiyan, F Mahmud
      Abstract: The experiment was carried out with 32 genotypes of Brassica rapa including two commercially cultivated varieties as checks to study their mean, range, cv (%) correlation co-efficient, and path co-efficient considering 10 different morphological characters at the experimental farm of SAU, Dhaka during November 2009 to February 2010. Significant variation was observed among all the genotypes for all the characters studied except 1000-seed weight. In general, genotypic correlations were higher than the phenotypic correlations. It indicates that there was an inherent association among them which was adversely influenced by the environment. Days to flowering showed positive significant correlation with days to maturity. Plant height showed positive significant correlation with number of primary branches/plant. Number of primary branches/plant showed positive significant correlation with siliquae/plant. Length of siliquae showed positive significant correlation with seeds/siliquae. Number of secondary branches, number of siliquae/plant, days to maturity, seeds/siliquae, and 1000-seed weight showed positive significant association with yield/plant. Path analysis showed that number of primary branches/plant, number of siliquae/plant, number of secondary branches/plant, and number of seeds/siliquae had direct effect on seed yield/plant. Considering analytical findings of correlation co-efficient, path co-efficient analysis and field performance, the genotypes G-15, G-19, G-1, G-3, G-4, G-10, G-18 G-21, and G-24 would be suitable for future hybridization programme.

  • Profitability of garlic (Allium sativum L.) cultivation in some selected
           areas of Bangladesh

    • Authors: MA Haque, MA Monayem Miah, MS Hossain, AN Luna, KS Rahman
      Abstract: The current production of garlic can’t meet up the increasing demand of Bangladesh. Due to unknown reasons, the area and production of garlic have not been increased at desired level. Therefore, the study was conducted in Magura and Faridpur districts during 2008-2009 to analyze the relative profitability, input-output relationship, and constraints to garlic production. Primary data were collected from 100 randomly selected garlic farmers for the study. Per hectare costs of garlic cultivation were Tk. 65493 and Tk. 51747 on full cost and variable cost basis. The major share of total cost was human labour (30%) and seed (25%). The yield of garlic was 6.15 metric tons per hectare. The gross margin and net return were Tk. 70660 and Tk 56914 per hectare, respectively. The benefit cost ratio was 1.87. The net returns from garlic cultivation were 68%, 59%, and 0.64% higher than mustard, groundnut and cabbage cultivation. Cobb-Douglas production function revealed that human labour, land preparation cost, manure, TSP, irrigation and insecticide had positive effect on the yield of garlic. Non-availability of HYV garlic seed, lack of technical knowledge about improved cultivation practices of garlic, infestation of insects and diseases and low market price were the major problems for garlic cultivation.

  • Effect of split application of nitrogen fertilizer on yield and yield
           attributes of transplanted aman rice (Oryza sativa L.)

    • Authors: Md Kamruzzaman, Md Abdul Kayum, Md Mainul Hasan, Md Mahmudul Hasan, Jaime A Teixeira Da Silva
      Abstract: Improper doses and splits of nitrogenous fertilizer are two major constraints achieving higher yield of transplanted aman rice in Bangladesh. A field experiment was carried out to study the effect of different levels and split application of nitrogen (N) fertilizer on yield and yield attributes of transplanted aman rice (var. BRRI dhan30). The experiment was laid out in a split-plot design with four split levels of N : T1 [⅓ N a t b asal + ⅓ N a t 2 5 d ays a fter transplanting (DAT) + ⅓ N at 50 DAT ], T2 [½ N at 25 DAT + ½ N at 50 DAT], T3 [⅓ N at 15 DAT + ⅓ N at 30 DAT + ⅓ N at 45 DAT], T4 [¼ at N 15 DAT + ½ N at 30 DAT + ¼ N at 45 DAT] in the main plot and four levels of N in the sub-plot: control (0 kg N/ha), N1 (40 kg N/ha), N2 (80 kg N/ha), and N3 (120 kg N/ha). Data collected were total tillers/hill, effective tillers/hill, number of grains/panicle, grain yield (t/ha), biological yield (t/ha) as well as some other morphological characters. Among the N splits, treatment T3 produced highest total tillers/hill (16.45), effective tillers/hill (12.73), panicle length (24.97 cm), grains/panicle (127.92), grain yield (5.53 t/ha), biological yield (12.87 t/ha), and harvest index (42.79%). Among the N levels, treatment N3 produced highest total tillers/hill (16.50), effective tillers/hill (12.69), grains/panicle (130.36), grain yield (5.40 t/ha), and biological yield (12.66 t/ha). Conversely, the treatment combination of N3 and T3 produced the highest value for most of the traits evaluated, namely total tillers/hill (18.03), effective tillers/hill (14.97), grains/panicle (137.48), grain yield (5.77 t/ha), biological yield (13.08 t/ha), and harvest index (44.10%). Hence, the treatment combination of N3 and T3 is suggested to bring higher economic benefit from transplanted aman rice in the study area.

  • Effect of seed stalk pruning and boron application on the seed yield of
           summer onion (Allium cepa L.) in the high barind tract

    • Authors: MMR Sarker, MJU Sarker, ASMMR Khan, MS Islam, MS Hossain
      Abstract: The experiment was carried out at FSRD site, Kadamshahar, Godagari, Rajshahi during 2009-10 and 2010-11 to find out the number of seed stalk and optimum boron dose for seed production of summer onion in High Barind Tract (AEZ 26). The treatments comprised three levels of seed stalk (0, 4, and 6) and three rates of boron application (0, 1, and 2 kg/ha). It revealed that the seed stalks and boron either in single or combination had significant effect on the yield and yield contributing characters of onion seed. The combination comprising 4 stalks with 2 kg B/ha and 6 stalks with 1 kg B/ha were found to be the best choice for achieving higher seed yield of onion. The highest seeded fruit/umbel (4.06 and 4.55) and seed yield (669 and 713 kg/ha) were recorded from 6 stalks/plant fertilized with 1 kg boron/ha which was statistically identical to 6 stalks/plant fertilized with 2 kg boron/ha and 4 stalks/plant with 2 kg/ha boron in the High Barind Tract.

  • Evaluation of maintainer and restorer lines for yield and yield
           contributing traits of rice (Oryza sativa L.)

    • Authors: MJ Hasan, Umma Kulsum, LF Lipi, A Akter, AKM Shamsuddin
      Abstract: An experiment was conducted at Bangladesh Rice Research Institute (BRRI), Gazipur during T.Aman season of 2007 with a view to evaluating seven maintainer and 30 restorer lines for yield and yield contributing characters for selecting promising maintainer and restorer lines for developing rice hybrids in our local environment. Significant variations were noticed among the parental lines for all the characters studied. The CMS lines Gan46A and BRRI9A could be used as female parents in hybrid seed production due to good yield and yield contributing characters recorded in their corresponding maintainer lines. Restorer line BR168R could offer high yield potentiality in heterosis breeding due to its superior yield contributing characters in local environment.

      Abstract: An experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during October 2006 to May 2007 to evaluate the effects of zinc, boron, and molybdenum on the seed yield of carrot. The soil of the studied field was deficient in zinc, boron, and molybdenum and represents Salna Series of Shallow Red Brown Terrace under Madhupur Tract (AEZ-28). Four (4) levels each of zinc (0, 2.0, 4.0, and 6.0 kg/ha), boron (0, 1.0, 2.0, and 3.0 kg/ha) and molybdenum (0, 0.5, 1.0, and 1.5 kg/ha) were used to formulate 11 treatment combinations to observe their effects on the seed yield of carrot (cv. Bejo Shetal). A blanked dose of N120P54K150S20 kg/ha was also applied to nourish the crop. The experiment was laid out in a randomized complete block design with three replications. The seed yield of carrot was significantly increased due to integrated effects of zinc, boron and molybdenum. The highest seed yield (362.28 kg/ha) was found with Zn4.0B2.0Mo1.0 kg/ha combination, which was 283% higher over control. The maximum germination percentage (91.30) and vigor index (4.99) of seed was also recorded from the same treatment package and thus may be recommended for the production of carrot seed in the studied or alike area of the country.
