  • Potential of kaffir lime (Citrus hystrix) leaf extract as biopesticide in
           improving pre and post-harvest quality of chili (Capsicum annuum)

    • Abstract: Purpose: Chilli production in Malaysia is declining due to production problems such as pest and diseases which cause plants to become stunted, unhealthy, and damaged. To overcome this problem, most farmers prefer using chemical fertilizers and pesticides due to their fast reaction and eff ectiveness. In long term, application of these chemicals input may lead to an environmental damage and human health problems. To conserve our nature, the use of natural input in agriculture is highly recommended. Research Method: This study was conducted to identify the potential of plant extract, namely kaffi r lime in increasing the plant productivity and reducing the severity of pests for chilli trees. The study was performed by spraying the chilli trees with 25, 50, and 75% (v/v) kaffi r lime extracts. Controls consisted of plants without any treatment as negative control and plants applied with a commercial chemical pesticide as positive control. Findings: Results indicated that there were signifi cant diff erences (p<0.05) between treatments with respect to all parameters including pre-harvest (plant height and pest severity) and postharvest (fresh weight and number of chilli pods) parameters except for the stem and crown diameter, soluble solid concentration, fruit fi rmness and colour measurement of chilli. The results found that chilli plants sprayed with 25% kaffi r lime extract had the lowest pest infestation. Moreover, application of the 25% kaffi r lime extract had produced the heaviest weight of chilli fruits and the highest number of chilli pods compared to other treatments including the positive control (chemical pesticide). Therefore, it was concluded that 25% kaffi r lime extract produced healthier chilli plants, higher yield and better quality of chilli. Originality/ Value: Limited number of studies are available on eff ectiveness of kaffi r lime-based insecticides. Therefore, this study was conducted as an eff ort towards understanding the versatility of kaffi r lime leaves extraction as an alternative pesticide on chilli plants’ pre- and postharvest performance.

  • Can Biofilm biofertilizer cut down chemical fertilizers in leafy vegetable
           cultivation' A case study with Centella asiatica (Gotukola)

    • Abstract: Purpose: In Sri Lanka, a higher usage of chemical fertilizers (CF) has been observed in agriculture which affects negatively for health and wellbeing of consumers as well as environment. Biofilm biofertilizer (BFBF) is a novel technology which is being practiced in many crops to enhance the productivity while improving soil quality. However, the BFBF has not been applied for leafy vegetables thus far. This study was conducted to introduce BFBF to C. asiatica (Gotukola) cultivation as a case study, in order to reduce the usage of CF.
      Research method: Firstly, a field experiment was carried out to evaluate the minimum CF rate that would not hamper the yield of C. asiatica cultivation. Then, different combinations of reduced rates of the minimum CF level and BFBF (Biofilm-veg™) were applied with a control of no amendments, and yield was recorded to explore the possibility of CF reduction with the BFBF application. One-way ANOVA, Tukey’s HSD test, and cost-benefit analysis were used to compare the treatments.
      Findings: The study revealed that even with only 60% of the farmers’ CF rate, there was no observable yield compromise. Thus, the optimum CF requirement for the crop was identified as 60% of the farmers’ current CF rate. By coupling of BFBF the amount of CF could be brought further down to 48% of farmers’ current CF rate. Furthermore, the application of 48%CF+BFBF produced a plant growth comparable to that with 100% CF.
      Research limitations: There were some practical limitations such as long dry spells and also finding suitable fields for the experiment, due to farmers' hesitation on possible yield reduction.
      Originality: Application of BFBF is an effective method to cut down CF by half in C. asiatica cultivation, thus minimizing the adverse effects of CF. Several studies have been conducted thus far to analyze the possibility of biofertilization in cutting down CF in agriculture, but they have only been limited to inoculation of isolated soil microbial mixtures. Present study is the first attempt to evaluate the capability of developed microbial biofilm-based BFBF application in reducing CF use in leafy vegetable cultivation. Published on 2022-09-01 00:00:00
  • A strategic model for empowering farmers by improving livelihood security
           through organic farming practices in Tamil Nadu, India

    • Abstract: Purpose: There is a particular paucity of information emanating from Tamil Nadu state, where organic farming appears to have a promising future. Some of the constraints revealed from primary sources suggest to the importance for a comprehensive study that would resulting in a strategic model framework for sustainable organic farming in Tamil Nadu. Research Method: Precisely 180 organic farming practitioners from the Coimbatore, Erode, and Tiruppur districts in Tamil Nadu were selected through purposive random sampling method. A semi-structured questionnaire and a personnel interview style were used to collect data. To determine significant contributing independent variables that determine the impact of organic farming, a step-down regression approach was employed. Findings: The majorities of participants were old-aged, had undergone collegiate to secondary education, had received organic farming training, and owned low livestock. Though there was a moderate level of media exposure, extension personal interaction, risk and scientific orientation among the respondents. Farmers' perceptions about environmentally friendly conservation practices, the use of organic manures, the profitability of organic farming, and environmental degradation ranged from moderate to high levels. Independent variables accounted for 77.30 percent of the variation in organic farming's impact on farmer livelihood security. Based on these observations, a model has been proposed for designing a future strategy. Originality/value: The proposed model will serve as a wake-up call for policymakers and concerned officials in framing new programs from the standpoint of organic farming.

  • Antioxidant Capacity and Nutritional Value of Peels and Seeds of Selected
           Pomegranate (Punica granatum L.) Cultivars from Sri Lanka

    • Abstract: Purpose: Nonedible portion of Pomegranate is reported to be rich with a diverse range of phytochemicals which embrace with health promotive features. Though antioxidant power and nutritive value of fruit juice are well known, knowledge of nonedible fraction is very poor. Hence, evaluation of antioxidant power and nutritional value of fruit peel and seed of pomegranates was targeted. Research Method: IC50, Ferric Reducing Antioxidant Power (FRAP), Total Phenolic (TPC), Total Flavonoid (TFC), Total Anthocyanin and pro-anthocyanidin Contents (ProAC) were determined. Nutritional value was studied by proximate analysis. Findings: IC50, TPC, FRAP and TFC values of peels were ranged from 4.6 to 41.1μg/mL, 318±1.77 to 478±5.62 mg Gallic acid equivalent/g, 4.270±0.83 to 6.690±0.15 mM Fe2+/g and 52.64±0.24 to 75.99±0.849 Rutin equivalent mg/g respectively. Antioxidant power and TFC of all the peel extracts were well above as compared with juice and seed samples, the highest IC50 and TPC in Daya peel whereas the highest FRAP and TFC in Nimali and Kalpitiya red peels respectively. Kalpitiya red juice and peel had the highest TAC and ProAc. Proximate analysis revealed that Protein, lipid and fiber contents were higher in seeds than peels. Carbohydrate content of all the peels was higher than the seeds. Research Limitations: There were some practical limitations such as long dry spells and also finding suitable fields for the experiment, due to farmers’ hesitation on possible yield reduction. Originality/ Value: Findings reveal that selected cultivars of pomegranate peel possess exceptionally high antioxidant power and could be applied as an excellent source of natural antioxidant in future therapeutic and medicine and as a safer natural antioxidant in food industries. High nutrient contents in pomegranate by-products facilitate to develop nutritionally valuable components such as functional food ingredients and nutraceuticals. Published on 2022-09-01 00:00:00
  • A Review on the Management of Country Bean (Lablab purpureus L.)
           Diseases in Bangladesh

    • Abstract: Purpose: Country bean (Lablab purpureus L.) is an important pulse crop consumed as a vegetable in the central and south-western regions of Bangladesh after eggplant and taro. It promises to ameliorate nutritional demand from vegetables and has an excellent possibility for the world market. But the production is hampered due to infection of several diseases in field conditions. Research method: This study was undertaken based on secondary data of existing literature from Bangladesh and other parts of the world. So far, many research works were done on this issue but those were not available to the policy makers, extension workers, and public in a systematic manner to date. Findings: In this paper, we tried to bring forth different aspects of phytopathological problems of country bean. It usually undergoes stresses from different soilborne to seed-borne pathogens and expresses symptoms from the seedling stage to maturity. Crop protection largely depends on the integration of host plants, seeds, agronomic practices, environmental footprints, and the use of appropriate agrochemicals based on the epidemiology of target pathogens. Here, we also described effective management strategies against respective pathogens of the diverse category. These microorganisms attack at different stages of crop growth and can affect the host plants enormously to cause maximum yield loss. Research limitations: The study focused on the management of country bean diseases based on biological and chemical approaches. It presents limited information on specific technologies in different agroecological zones. Originality/Value: This study identified research gaps among Bangladesh and other countries. It also provides information to combat country bean diseases to the economic threshold level for ensuring sustainable crop yield. Published on 2022-09-01 00:00:00
  • Feeding potential and development of Chrysoperla carnea (Neuroptera:
           Chrysopidae) on Paracoccus marginatus (Hemiptera: Pseudococcidae) under
           no-choice conditions

    • Abstract: Purpose: Considering the predatory effectiveness of Chrysoperla carnea (Neuroptera: Chrysopidae), studies were carried out at National Agricultural Research Centre, Islamabad, Pakistan to determine the feeding potential and developmental period of its larval instars on Paracoccus marginatus (Hemiptera: Pseudococcidae). Research Method: Eggs, 1st, 2nd, and 3rd nymphal instars and adults of P. marginatus was provided to all three larval instars of C. carnea in a Completely Randomized Design experiment, replicated ten times. Findings: Results indicated that all C. carnea larval instars were found to feed on all P. marginatus stages. Overall mean consumption of C. carnea larvae on P. marginatus eggs, 1st, 2nd and 3rd instar nymphs, and adults was 1359.8, 1409.1, 1012.4, 1165.7 and 130.30 individuals, respectively. Third instar C. carnea larvae was more voracious than 2nd and 1st instars. The shortest developmental period (12.40±0.37 days) of C. carnea larvae was recorded on 3rd nymphal instar of P. marginatus. Moreover, C. carnea larvae took 14.90±0.23, 14.00±0.25, 13.10±0.23, and 13.60±0.34 days on eggs, first, second nymphal instars and adults of P. marginatus, respectively to complete their development. Originality/value: Therefore, it is suggested that C. carnea should be included as a key component in the integrated management of P. marginatus, especially its 3rd larval instar Published on 2022-09-01 00:00:00
  • Cytotoxicity and Nematicidal Potential of Leaf Extracts of Adansonia
           digitata and Khaya senegalensis on Root Knot Nematode (Meloidogyne
           incognita) Associated with Cabbage

    • Abstract: Purpose: Cabbage, an indispensable vegetable is often plagued by Meloidogyne incognita, a circumstance which lessens yield. Extracts of Khaya senegalensis and Adansonia digitata were appraised for possible nematicidal activity to check the menace of M. incognita sequel to the undesirable effect of synthetic nematicides in the environment. Research Method: Leaf materials were extracted in organic and aqueous extracts. The extracts were used as soil admix at 0, 150, 200 and 250 g/Kg soil, in a randomized complete block design experiment. Carbofuran a synthetic nematicide served as positive check for the extracts. Data was taken on vegetative growth, yield and nematode population. Lethality of the various extracts to brine shrimp larvae was also assessed. Findings: The aqueous extract was not as productive as the ethanol and methanol extracts. A. digitata extracts demonstrated weak nematicidal activity as against what was observed in cabbage plants treated with K. senegalensis extracts. Cytotoxicity evaluation of the organic and aqueous extracts of A. digitata indicated that the methanol extract expressed weak cytotoxicity (500 µg/ml - 1000 µg/ml), while the aqueous and ethanol extracts were not toxic to the brine shrimps (LC50 >1000µg/mL). K. senegalensis extracts were active against brine shrimp larvae with LC50 values <1000µg/mL The methanol and ethanol extracts demonstrated strong cytotoxicity with LC50 values <100µg/ml. Extracts from K. senegalensis significantly (p=0.05) increased the vegetative growth of cabbage plants. Originality/ Value: These results signify that the species have a probable use in the bio-pesticide industry, without any toxicity as the synthetics.

  • Enhancing in vitro growth of wheat seedlings under water stress
           using biopriming

    • Abstract: Purpose: Providing food for the world, growing population becomes more diffi cult with the increase of abiotic stresses due to climate change. The production of wheat, which is a major crop is under the threat of drought stress. The aim of this experiment was to fi nd out to what extent biopriming reduced the eff ects of drought on wheat (Triticum aestivum L. cv. Slemani-2) seedling growth under in vitro conditions. Research Method: In vitro planted seedlings were subjected to drought conditions using three diff erent watering regimes (normal [control], ½ reduced, and ¾ reduced) after biopriming the seeds with Azospirillum lipoferum, Frateuria aurantia, and Chlorella saccharophila. Physiological traits and growth characteristics were measured. ANOVA was performed according to the factorial layout in completely randomized experimental design with three replications using Microsoft Windows based COSTAT software (version 6.3). Findings: The experiment results showed that biopriming had reduced the eff ect of drought on chlorophyll concentration and root characteristics, especially under ½ reduced water application. A. lipoferum and C. saccharophila were more benefi cial for the seedlings than F. aurantia. Physiological and growth characteristics such as chlorophyll concentration were enhanced using biopriming, hence photosynthesis, root characters, and nutrient uptake. Research Limitations: The availability of previous studies and data on the microorganisms used werethe main constrain in the study. Conducting a study under controlled greenhouse conditions until harvest might provide more information as more parameters will be measured and data collected, especially at the anthesis stage as it is a crucial stage. Originality/ Value: This research provides a possible method to reduce drought impact on wheat crops bysuggesting biopriming with new microorganisms.

  • A Study on the Antioxidant and Active Compounds of Gardenia jasminoides
           Ellis (GJE) Leaves Extract

    • Abstract: Purpose: The aim of this study was to isolate and identify the active compound antioxidant fractions from Gardenia jasminoides Ellis leaves. Research Method: The antioxidant activity was determined using DPPH 0.1 mM (1:1), and was analyzed spectrophotometrically. In addition, separation was performed using column chromatography. The most active isolate was identified by UV-Vis, FT-IR, and LC-MS/MS. The quantitative analysis was done in three replicated. Findigs: It was discovered that the antioxidant activity in the semi-polar fraction (IC50 = 62,50 ppm) was higher than both the polar and non-polar fractions. Combining 295 isolates via column chromatography, 11 combined isolates were obtained (fA-fK). The fK isolate had the highest antioxidant activity of 90.38% and IC50 15.74 ppm. It also obtained 2 maximum wavelengths (336 and 275 nm) and could be categorised as flavonoid (flavonol with 3-OH substituted). The FTIR analysis also showed that the fK isolate had functional groups found in flavonoid. Finally, the identification of the fK isolate by LC-MS/MS showed that the compound at retention times of 5,91 and 5,06 minutes were kaempferol 3-O-rutinoside and rutin, respectively. Originality/ Value: Based on the obtained results, it was concluded that GJE leaves have the potential to be developed as a new and inexpensive source of flavonoids.
