    • Authors: MSA Khan, MA Karim, MM Haque, AJMS Karim, MAK Mian
      Pages: 333 - 345
      Abstract: The experiment was conducted at the experimental site of Agronomy Department, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Salna, Gazipur during the period from January to June 2011 to evaluate twenty selected soybean genotypes in respect of growth, dry matter production and yield. Genotypic variations in plant height, leaf area index, dry matter and its distribution, crop growth rate and seed yield were observed. The plant height ranged from 40.33 to 63.17 cm, leaf area index varied from 3.01 to 8.13 at 75 days after emergence, total dry matter ranged from 12.25 to 24.71 g per plant at 90 days after emergence (DAE). The seed yield ranged from 1745 to 3640 kg per hectare. The genotypes BGM 02093, BD 2329, BD 2340, BD 2336, Galarsum, BD 2331 and G00015 yielded 3825, 3447, 3573, 3737, 3115, 3542 and 3762 kg per hectare, respectively and gave higher than others contributed by higher crop growth rate with maximum number of filled pods. Seed yield of soybean was positively related to total dry matter at 45 DAE (Y = 632.19 + 659.31X, R2= 0.46) and 60 DAE (Y= 95.335 + 405.53X, R2 = 0.48). The filled pods per plant had good relationship with seed yield (Y = 1397 + 41.85X, R2 = 0.41) than other components.Bangladesh J. Agril. Res. 40(3): 333-345, September 2015

  • Farmers land tenure arrangements and technical efficiency of growing crops
           in some selected upazilas of Bangladesh

    • Authors: MA Islam, KL Maharjan
      Pages: 347 - 361
      Abstract: There are different land tenure arrangements in crop cultivation in Bangladesh. It is needed to detect how farmers could maximize the benefits from proper utilization of their resources and technologies in these prevailing different land tenure arrangements in crop cultivation. The main quest of this study is to analyze the actual production level and how much is deviated from maximum attainable production level in terms of technical efficiencybased on average gross revenue of output ha-1 in the cultivated various types of crops among different categories of farmers and identifies the impact of the factors associated with technical efficiency.In search of this research question a case study was conducted in two Upazilas (Sub districts) in Bangladesh based on cross section data. This data were collected from January to March, 2013. Age of the household head, education, farm size, off-farm income and other concerned issues were assessed. Maximum likelihood estimation and ordinary least square regression techniques were used to estimate the parameters of the stochastic production frontier.Ordinary least square regression was used to identify the factors associated with technical efficiency. The study reveals that the technical efficiency varied among different categories of farmers. But land rent (0.0575) and weed management (0.0838) had significant positive impact on technical efficiency. This detects the potentiality to improve the technical efficiency by taking proper measures in land tenure arrangements in consideration of land rent andprovide required weed management support for the farmers.Bangladesh J.

  • Factors affecting the adoption of improved varieties of mustard
           cultivation in some selected sites of Bangladesh

    • Authors: MA Monayem Miah, Sadia Afroz, MA Rashid, SAM Shiblee
      Pages: 363 - 379
      Abstract: Mustard is a leading oil crop in Bangladesh. Relevant data and information on the adoption of improved mustard varieties is very scanty and sporadic in Bangladesh. Therefore, an attempt was made to assess the extent of adoption of improved mustard varieties and their management practices at farm level. The study used data from 540 mustard growing farmers under Manikgonj, Rajshahi and Dinajpur districts. Probit regression model along with other descriptive statistics were used to analyze the collected data. Analysis revealed that the farm level adoption of different production practices were not encouraging as most farmers did not follow the recommendations made by Bangladesh Agricultural Research Institute (BARI) for mustard cultivation. The variety adoption scenario was also discouraging since only 40% of the farmers cultivated improved mustard varieties. However, farmers showed positive attitude towards adoption of improved mustard varieties since about 53% of the adopters wanted to increase area under improve mustard cultivation in next growing season considering the high yielding ability, low cultivation cost, high profit, and less labour requirements. Although mustard is considered to be a profitable crop, many farmers showed negative attitude towards its production due to some drawbacks. Non-availability of improved mustard seed was also found to be a barrier to its adoption at farm level.Bangladesh J. Agril. Res. 40(3): 363-379, September 2015

      Pages: 381 - 390
      Abstract: Studies were made on the biology of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guenee feeding on peeled potato tubers as host in the laboratory. It was observed that moths were active at night for mating, oviposition and adult emergence. Adult emergence started just after sunset and it was maximum (88.90%) during the first half of the night. Maximum mating occurred at late night where 90.80% mating occurred in the first night of adult emergence. Oviposition occurred in the second night of emergence when 86.62% of eggs were deposited during the first half of the night. A female laid 288.05 eggs in 2.65 days in summer and 185.55 eggs in 2.70 days in winter. The egg hatching and larval and pupal period of BSFB were 4.13, 10.40 and 6.60 days, respectively in summer and 6.90, 14.50 and 10.65 days in winter. BSFB needs 10.40 and 14.50 days to complete its larval period in summer and winter, respectively. Pupal period lasted for 5-13 days. Life cycle from egg to adult was 17-44 days. The longevity of male and female adult was 3.50 and 6.20 days in summer and 4.85 and 8.90 days in winter. Temperature in two seasons showed variations in the biology of BSFB.Bangladesh J. Agril.

           (Cicer arietinum L.)

    • Authors: M Shahiduzzaman
      Pages: 391 - 398
      Abstract: A field experiment was carried out at Regional Pulses Research Station (RPRS), Madaripur during Rabi season of 2011-12 and 2012-13 to evaluate the most effective fungicides in controlling Botrytis Gray Mold (BGM) of Chickpea. Five different fungicides e.g. Propiconazole (Tilt 250 EC), Carbendazim (Bavistin DF), Fenamidone+Mancozeb (Secure 600 WG), Difenoconazole (Score 250 EC), Tebuconazole (Folicure 250 EC) were evaluated under natural condition. Results revealed that among the five fungicides Fenamidone+Mancozeb (Secure 600WG) sprayed at the rate of 1g/L with 7 days interval gave the lowest BGM score of 3.80 and 4.00 in 1-9 scale during 2011-12 and 2012-13 and produced highest yield of 1547 and 1443 kg/ha, respectively. Besides, the highest BGM was scored by the untreated control plot (6.26 and 6.33) and produced the lowest yield of 988 and 853 kg/ha during the two consecutive years.Bangladesh J. Agril.

    • Authors: MA Mannan, KS Islam, M Jahan
      Pages: 399 - 407
      Abstract: Brinjal shoot and fruit borer infestation varied significantly in relation to plant age and season. The peak shoot infestation was 8.56% in the 10th week of transplanting. No infestation of BSFB was found up to 5 weeks of transplanting. The shoot infestation was initiated in the 6th week of transplanting which increased to a little higher level in the next week. Then it showed an exponential increase of shoot infestation up to 10th week after which it declined steadily. Flowering and fruit setting started in the 9th week of transplanting. Infestation of brinjal shoot and fruit borer (BSFB) shifted to fruits from shoots causing a steady declined in the trend of shoot infestation. Plant age had significant effect (r2=0.87) on fruit infestation. The fruit infestation reached the highest level (38.56%) in 14th week of transplanting. However, the level of infestation at different ages of the plant may vary depending on the location, temperature, variety etc. The shoots and fruits of brinjal plant were found to be infested by BSFB throughout the year, although the level of infestation varied. Maximum shoot and fruit infestation was found in the month of September.Bangladesh J. Agril. Res. 40(3): 399-407, September 2015

  • Profitability of betel leaf (Piper betle L.) cultivation in some selected
           sites of Bangladesh

    • Authors: QMS Islam, MA Matin, MA Rashid, MS Hoq, - Moniruzzaman
      Pages: 409 - 420
      Abstract: The study was conducted in four betel leaf growing areas, namely Barisal, Chittagong, Rajshahi and Kustia district during 2013-14 to assess the cultivation practices, physical productivity, profitability, and to explore the constraints to betel leaf cultivation. The study has been designed to investigate the economics of betel leaf production considering intensive cultivated areas for recent information in Bangladesh. From each district, two upazilas were selected considering the concentration of betel leaf growers and easy access. Also from each upazila, two blocks and from each block 20 farmers were selected with the consultation of Upazila Agriculture Officer and Sub Assistant Agriculture Officer. The study revealed that betel leaf cultivation was profitable in the study areas, although BCR in the first and second years was below one which was due to high initial cost. The highest yield and gross return of betel leaf cultivation were in the fifth year. The benefit cost ratio was found highest in 6-10 year followed by 5th and 11-15 year. The benefit cost ratio at 12%, 15% and 20% rate of interest were 1.27, 1.25 and 1.21 respectively. Internal rate of return (IRR) was calculated 62% in current situation, IRR 37% was found by 10% decrease of return and 39% by 10% increase of cost. The problems like leaf rot disease, high price of boroj materials, low price of betel leaf, high price of oilcake, etc. were facing by the betel leaf farmers.Bangladesh J. Agril.

  • Genetic divergence in Brassica rapa L.

    • Authors: S Naznin, MA Kawochar, S Sultana, N Zeba, SR Bhuiyan
      Pages: 421 - 433
      Abstract: Different multivariate analysis techniques were used to classify 33 Brassica rapa L. genotypes. The genotypes were grouped into five clusters. Cluster I contained the maximum number of genotypes. Cluster III earned the highest cluster mean value for number of primary branches/plant, number of secondary branches/plant, number of siliquae/plant and seed yield/plant. Therefore, more emphasis can be given on cluster III for selecting genotypes as parents for the hybridization program. The highest intra-cluster distance (3.822) was found in cluster I and the lowest (0.000) in cluster V. The highest inter-cluster distance (15.705) was observed between clusters III and V showing wide diversity among the groups. Principal component analysis (PCA) showed that the first three principal components accounted for 99.38 % of the total variation observed. Analysis of the factor loading of the component character indicated that the characters number of siliquae/plant, plant height and days to maturity were found responsible for genetic divergence. The role of number of siliquae/plant in both the vectors was important components for genetic divergence in these materials. Among the possible 528 combinations, the highest inter-genotypic distance (1.5975) was observed between G-27 (BARI sarisha-9 x BARI sarisha-6 S-62) and G-31 (BARI sarisha-15). Considering group and inter-genotypic distance, cluster mean, contribution of different characters towards the total divergence and other agronomic performance the genotypes G- 19 (BARI sarisha-6 x TORI-7 S-48), G-20 (F6 x BARI sarisha-9 S-52), G-27 and G-30 (BARI sarisha-6 x TORI-7 S-37) from cluster III; G-26 (F6 x BARI sarisha-9 S-15) and G-31 from cluster IV and G-33 (BARI sarisha-6) from cluster V would be considered as better parents for future hybridization program.Bangladesh J.

      Pages: 435 - 450
      Abstract: The experiment was carried out with 50 wheat lines to study their intergenotypic variability, heritability, GCV, PCV, genetic advance, and CV percent considering 14 morphological characters at the experimental field of Regional Wheat Research Centre RWRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during November 2010 to March 2010. Significant variation was observed among the genotypes for all characters studied. High GCV and PCV values were observed for grain filling duration, grain filling rate, and seed yield. High heritability along with higher genetic advance was observed for DTH, DTA, DPM, GFD, GFR, PHT, CHLA, spikelets/spk., and yield kg/ha. The remaining traits showed lower heritability coupled with low genetic advance in percent of mean. Considering variability among the genotypes, heritability, genetic advance, percent co-efficient of variation, and field performances, the genotypes G 3, G 10, G 11, G 12, G13, G 21, G 29, G 35, G 38, G 40, G 46 and G 48 were found suitable for future breeding programme.Bangladesh J.

      Pages: 451 - 463
      Abstract: The study was carried out to assess the larvicidal efficacies of some indigenous plant seed extracts against epilachna beetle, Epilachna vigintioctopunctata in the laboratory of the Department of Entomology, HSTU, Dinajpur, Bangladesh. Petroleum ether and methanol solvent extracts of ata (Annona squamosa), neem (Azadirachta indica), dhutura (Datura metel) and castor (Ricinus communis) seeds were evaluated for their larvicidal properties against the larval stage of E. vigintioctopunctata. The result revealed that all the tested plant extracts had more or less insecticidal effect against the larvae and their progeny. Among the plant extracts, ata seed extract in methanol solvent performed the highest toxicity (LD50 value 0.031 mg/insect) in larval stage after 72 hours exposure time. The effects of the extracts on fecundity, fertility and F1 adult emergence of the epilachna beetle at doses 4.0, 2.0 and 1.0 ml/l of water including untreated control were also evaluated. The result indicated that, among the extracts, ata seed extract at maximum dose (4.0 ml/l water) showed the highest efficacy with the inhibition of total eggs (74.1%), viable eggs (80.4%) and number of emergent adult progeny (87.3%). The result also revealed that the number of eggs, number of viable eggs and F1 progeny production decreased with the increase of doses. All the treated doses effectively reduced the epilachna beetle as compared to untreated control.Bangladesh J. Agril. Res. 40(3): 451-463, September 2015

      Abstract: This experiment was conducted during September, 2011 to March, 2012 in the experimental field of Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to find out the effect of planting date on the yield of broccoli genotypes. There were five genotypes viz. Early green, Forest green, Green calabrese, Premium crop and Green king and four planting dates viz. 2 October, 27 October, 21 November and 16 December. The treatment effects were statistically analyzed and found significant in most of the characters studied. Genotype Green calabrese was the highest in average plant height (53.70 cm). Green king produced the maximum spread diameter (69.23 cm), stem diameter (30.35 mm) and early initiation of floral head. Genotype Early green performed the best regarding head weight (343.87 g), yield per plant (477.4 g) and yield (19.10 t/ha). Broccoli planted on 21 November initiated early flower head, maximum head diameter (16.99 cm), head weight (314.49 g), yield per plant (453.64 g) and total yield (18.15 t/ha). The genotype Early green planted on 21 November showed the best performance in yield per plant (580.17 g) and yield hectare (23.21 t/ha).Bangladesh J. Agril. Res. 40(3): 465-478, September 2015

  • Variability, correlation and path analysis in pumpkin (Cucurbita moschata

    • Authors: S Sultana, MA Kawochar, S Naznin, A Siddika, F Mahmud
      Pages: 479 - 489
      Abstract: Twenty one genotypes of pumpkin (Cucurbita moschata L.) were evaluated to measure the variability among the genotypes for several characters, estimate genetic parameters, association among the characters and their contribution to yield. There was a great deal of significant variation for all the characters among the genotypes. High variability was observed in number of female flowers/plant, number of male flowers/plant, single fruit weight and fruit yield/plant. All the characters except days to first male flowering and days to first female flowering showed high heritability along with high genetic advance in percent of mean. The positive and strong association of number of female flowers/plant (rg=0.918, rp=0.839), number of male flowers/plant (rg=0.687, rp=0.638), fruit length (rg=0.691, rp= 0.520), fruit breadth (rg=0.518, rp=0.420) and single fruit weight (rg=0.492, rp= 0.431) with fruit yield/plant revealed the importance of these characters in determining fruit yield/plant. On the other hand, days to first male flowering (rg = -0.623, rp = -0.550) and days to first female flowering (rg= - 0.689, rp= -0.543) correlated significantly and negatively with fruit yield/plant. The path co-efficient analysis revealed that the highest positive direct effect was recorded in number of female flowers (0.887) to fruit yield and high direct effect was found in case of days to first female flowering (0.798). Fruit breadth was observed to have the highest positive indirect effect (0.899). In case of fruit length (0.381) and single fruit weight (0.398), the significant positive correlation with fruit yield/plant was observed because of the combination of the direct and indirect effects of fruit length and single fruit weight to fruit yield/plant. Overall, the results indicated that days to first female flowering, number of female flowers, fruit length, fruit breadth and single fruit weight can be used as useful selection criteria to increase fruit yield/plant in pumpkin.Bangladesh J.

  • Effect of sowing date and plant spacing on seed production of cauliflower

    • Authors: MF Hossain, N Ara, MR Uddin, MR Islam, MG Azam
      Pages: 491 - 500
      Abstract: The experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna during rabi season of 2011-2012 and 2012-2013 to find out the appropriate sowing date and optimum plant spacing for seed production of cauliflower (var. BARI Phulcopi-1). Four sowing dates viz. 20 September, 1 October, 10 October and 20 October and three plant spacing viz. 60 cm × 50 cm, 60 cm × 60 cm and 60 cm × 70 cm were used as treatment variables. Significant variation in seed yield and yield contributing characters of cauliflower were observed due to execution of different sowing dates and plant spacing. Number of branches plant-1, number of pods plant-1 and number of seeds pod-1 showed the highest in 1 October sowing as a result the highest seed yield (361.69 kgha-1) was obtained from same date of sowing. Sowing on 10 October and 20 October reduced seed yield drastically compared to that obtained from 1 October sowing. The lowest seed yield (188.54 kgha-1) was obtained from 20 October sowing. On the contrary, closer spacing (60 cm × 50 cm) produced the highest seed yield (315.88 kgha-1) and the wider spacing (60 cm × 70 cm) produced the lowest seed yield (254.07 kgha-1). However, combination of 1 October sowing with 60 cm × 50 cm plant spacing produced the highest seed yield (414.81 kgha-1) due to higher number of seeds pod-1. The seed yield decreased after 10 October sowing irrespective of plant spacing. So, early sowing (1 October) with closer spacing (60 cm× 50 cm) would be economically profitable for cauliflower seed production in North-Western part of Bangladesh.Bangladesh J. Agril.

  • Response of lentil to bio and chemical fertilizers at farmer’s field

    • Authors: MAH Bhuiyan, MS Islam, MS Ahmed
      Pages: 501 - 506
      Abstract: Field trials were carried out at the Farming System Research & Development site, Hatgavindapur, Faridpur, On-Farm Research Division of Bangladesh Agricultural Research Institute during rabi seasons of 2006-2007 and 2007-2008 with the objectives to evaluate the response of lentil to Rhizobium biofertilizer and to reduce the use of N-fertilizer under farmer’s field condition. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Unit plot size was 4 m x 5 m. Four fertilizer treatments viz. T1: 24-22-42-20-5 kg N-P-K-S-Zn ha-1, T2: 50-22-42-20-5 kg N-P-K-S-Zn ha-1, T3: 0-22-42-20-5 kg N- P-K-S-Zn ha-1 + Rhizobium Inoculum and T4: Farmer’s practices were studied. Farmer’s practice was 25-18-21-0-0 kg N-P-K-S-Zn ha-1. BARI Masur-4 and peat based rhizobial inoculum (strain BARI RLc-102) @ 1.5 kg ha-1 were used. Result revealed that application of Rhizobium biofertilizer along with PKSZn chemical fertilizers produced the highest nodule number (11.62 plant-1) and nodule weight (11.94 mg plant-1), and the seed yield 1.44 t ha-1. The seed yield was higher in T3 treatments (N0P22K42S20Zn5 + Inoculum) than T1 (N24P22K42S20Zn5) and T2 (N50P22K42S20Zn5) treatments. No variation was observed in seed yield in treatments T1, T2 and T3 but significantly different from farmer’s practice. Farmer’s practice showed the lowest yield. Economic analysis revealed that T3 treatment i.e. PKSZn plus Rhizobium inoculum gave the highest 5.36 benefit cost ratio (BCR) followed by T1 4.68 and T2 3.61. It is evident from the experiment that application of biofertilizer can be used as substitute of nitrogenous fertilizer for higher yield of lentil at farmer’s field in Faridpur.Bangladesh J. Agril.
