Eco-friendly management of leaf and fruit scarring beetle (Basilepta spp., Colaspis spp.) by using bio-pesticides and mechanical barriers

Paper ID- AMA-25-03-2023-12145

Efficacy of bio-pesticides and mechanical barriers for eco-friendly management of banana against scarring beetle were evaluated in two field experiments at Bhola Paswan Shastri Agricultural College, Purnea, Bihar during 2014 to 2017. Neem seed kernel powder @ 15 g per banana whorl was found most effective against banana scaring beetle among all evaluated bio-pesticides and lower down the pest population (13.63 /plant) as compare to control (63.84/plant). This treatment showed lowest number of scars (13.43 scars/20cm2 area of banana) as compare to control (66.72 scars/20cm2 area of banana). It was also found effective and perform better in enhancement of number of hands/bunch (7.44), number of fingers/hand (16.60) and yield/plant or bunch weight (19.43 Kg). For the assessment of different mechanical barriers for eco-friendly management of banana scaring beetle, another experiment was conducted for three consecutive years at same location. In this experiment sprayed neem oil (azadirachtin 0.1%) along with 17 GSM polypropylene bags which acted as mechanical barrier for the new flower of banana just before/during opening of flower. It was found most effective in reducing scarring beetle population (5.91/plant) as compare to control (62.25/plant). This treatment showed lowest infestation (scars) (2.79 scars/20cm2 area of banana) as compare to control (62.78 scars/20cm2 area of banana) and also produced highest bunch weight (24.56 kg). It also enhanced fingers per hand (7.84) as well as number of hands (17.66) per bunch. Scarring beetle infested fruits lost their marketability due to partial or complete damage and fetched very low market price. Earlier it was considered as minor pest and farmers were unaware about its prevalence and eco-friendly management regarding this emerging pest. Present investigations for eco-friendly management by using bio-pesticides and timing of application of mechanical barriers helps farmers in reducing the pest population economically.

The present investigation on “Performance of macro-propagated and sucker grown plants of banana cvs. Jahaji (AAA) and Barjahaji (AAA)” was carried out at the Horticulture Experimental Farm, Assam Agricultural University, Jorhat during the year 2017-18 and 2018-19, respectively. The main objective was to see the comparative performance of macro-propagated and sucker grown plants of banana with respect of growth, yield and yield attributing characters of banana. The present experiment was laid out in factorial RBD with five replications and with two factors with two levels. The first factor consist two two levels namely ahaji and Barjahaji cultivars. The observations were recorded on yield and yield attributing characterstics/parameters. Quality parameters such as total sugars (16.96 %), reducing sugar (8.00 %), non-reducing sugars (8.21 %), TSS (20.64 º Brix), soluble fruit fibre (187.84 mg/100g) were found highest in the macro-propagated plantlets of Jahaji and the lowest mortality was found in (0.4%). Macro-propagated plantlets perform better in the field than suckers in all parameters of growth and yield. Negligible infestation of pest-diseases was observed in macro-propagated plants. Jahaji cultivar were superior to Barjahaji in the growth and yield attributes. Macro-propagated plants of Jahaji are best for cultivation in the North-Eastern region. During the first year and second year of the investigation macro-propagated plants were found best among all the treatments with respect to growth, yield and quality attributing characters. Field performance of macro propagated plantlets is better than conventional suckers [10]. The occurrence of disease-pests is very less in case of macro-propagated banana plants. Macro-propagated plants are tolerance against insect-pests and diseases.

Economics of Mango Production and Constraints Faced by Growers in Western Undulating Agro Climatic Zone of Odisha

Paper ID- AMA-21-03-2023-12140

Mango is an important commercially farmed fruit crop and it is very popular due to its wide range of adaptability and high nutritive content. In order to understand the economics of mango production and the challenges faced by growers in production, the current study was carried out in the Kalahandi area of Odisha state of India. The study used a multi-stage sampling design with a 60-person sample size. Its information was gathered for 2021-22. Use a straightforward cost-return calculation to calculate the cost and profit of mango farming. The growers' challenges with mango production and marketing were ranked using the percentage method. Mango cultivation costs per quintal were calculated to be Rs. 1167.43, while per-hectare gross returns were, on average, Rs. 303944.67. The overall output-input ratio was 2.14, which is greater than unity and showed that mango production was a successful business. Lack of knowledge about high-yielding mango varieties, the issue of high temperatures, the problem of unavailability of transportation in sick, heavy rains, winds, and hailstones during flowering and fruit development stages, lack of extension services, and a lack of storage facilities near the growing area were among the production and marketing challenges faced by mango growers. The findings are in line with those of Yadav et al. (2010) who identified fruit drop as one of the major restrictions on mango output.

Effect of irrigation management on growth, yield, water use efficiency and economics of fennel (Foeniculum vulgare Mill)

Paper ID- AMA-19-03-2023-12136

A field trial was carried out at SKN College of Agriculture, Jobner, Jaipur (Rajasthan) during rabi 2018-19, 2019-20 and 2020-21to find out the effect of different irrigation methods (flood irrigation, sprinkler irrigation and drip irrigation) on growth, yield, water use efficiency and economics of fennel (Foeniculum vulgare Mill.). The experiment comprising of five treatments viz. flood irrigation, sprinkler irrigation, drip irrigation at 0.8 IW/CPE ratio, drip irrigation at 1.0 IW/CPE ratio and drip irrigation at 1.2 IW/CPE ratio. Research findings of present experiment revealed that the drip irrigation treatments brought an additive effect in increasing growth, yield, water use efficiency, quality and economics of fennel. Drip irrigation at 0.8 IW/CPE ratio produced higher plant height (105.33 cm), umbels/plant (27.44), umbellets /umbel (22.40), seeds/umbel (330.73), seed yield (25.56 q/ha), harvest index (30.61%), essential oil (1.70 %), net returns (Rs 135720/ha), B:C ratio (3.43) and water use efficiency (7.22 kg/ha-mm) along with 33.03% of water saving which was significantly superior in the comparison of flood irrigation and sprinkler irrigation.

Genetic Parameters and Characterization of Rice Genotypes under Drought Stress

Paper ID- AMA-17-03-2023-12132

Two experiments were conducted to evaluate seventeen rice genotypes behavior under normal and water deficit conditions during the 2019 and 2020 rice growing seasons to screen and identify the genotypes and determine the remarkable criteria for selection. The study revealed that environmental conditions, genotypes, and their interaction (GEI) mean squares were found to be highly significant for all physiological and morphological characters studied. Whereas, the genotypes that show high mean values for physiological and morphological characters are tolerant to water shortages. The grain yield plant-1 was investigated under normal and drought conditions, and it was positively significant associated with soluble sugar, peroxidase activity, the number of panicles plant-1, and 100-grain weight under drought conditions. On the other hand, a significant negative correlation was observed with soluble sugar, catalase activity, peroxidase activity, stomatal conductance, Na content, and sterility percentage under both normal and drought conditions, respectively.
