Repellent and contact activities of Techno oil and Berna star against Tribolium castaneum (Herbst) and Rhyzopertha dominica (F.).

Paper ID- AMA-14-09-2022-11678

Techno oil and Berna star are two plant extracted products which are used as safe pesticides. Tribolium castaneum (Herbst) and Rhyzopertha dominica (F.) are two major stored product insects. The two tested products were evaluated against R. dominica and T. castaneum adults using two bioassays evaluating their repellency and contact effects. Berna star had stronger repellent activity against T. castaneum. In contrast, Techno oil had the greatest repellency against R. dominica. Furthermore in thin film method Berna star had stronger effect against the two tested insects compared to Techno oil at all exposure periods. After 24 h of exposure the two components had no effect on T. castaneum while after 72 h of exposure the mortality was 100% with all concentrations for R. dominica for two tested components. Using mixing with medium method there was no effect on T. castaneum before 7 days for both tested components, while for R. dominica both tested components had toxicity effect for all used concentrations. For R. dominica after one, three and four days of exposure Techno oil had the stronger effect while for T. castaneum Berna star had stronger effect at all exposure periods. Based on LT50 with the highest concentration (40000 mg/kg) Berna star had stronger effect on both tested insects with LT50 of 6.06 and 1.41 h for T. castaneum and R. dominica respectively. Both tested products achieved 100% reduction against the two tested insects.

Eco physiology of litchi in relation to variable climatic factors

Paper ID- AMA-14-09-2022-11676

The main emphasis was given on the effects of the environmental factors viz: light, temperature, water and gaseous exchange parameters on physiology of litchi production. Environmental stresses can cause morpho-anatomical, physiological and biochemical changes in crops, resulting in a strong profit reduction. The interest has shown on the effect of temperature during panicle emergence, flower development and fruit sun burn and cracking. The stress factors like water stress, cold winter are the triggering factors to induce dormancy which promotes flowering. High temperature and low humidity during fruit growth increases sun burn and fruit cracking. Water stress during fruiting is vulnerable with respect to fruit drop. Understanding environmental factors and their interaction with physiological processes is extremely important for economically sustainable litchi production.

Effect of New Plant Growth Regulator Prohexadione-Ca on Horticultural Crops

Paper ID- AMA-14-09-2022-11675

Prohexadione-Ca is a plant bioregulator primarily used to suppress excessive vegetative growth in fruit trees and other crops. It is most effective in high density plantings to reduce and control crown growth and height. In addition, effects on the occurrence of bacterial and fungal diseases and on insect pests are often observed. In addition, this may reduce fruit abortion and thereby increase fruit set. It is relatively short-lived and has very favorable toxicological and ecotoxicological properties. Finally, it leads to a reduction in ethylene formation because structural similarity to ascorbic acid, a co-substrate of aminocyclopropanecarboxylic acid oxidase, another dioxygenase involved in ethylene biosynthesis. Reduced ethylene levels together with increased availability of assimilate no longer required for shoot growth explain the increase in fruit set. It improves the process of photosynthesis by increasing the concentration of chlorophyll per unit area of the leaf and the content of carbohydrates in the tissues of the bark. It participates in secondary metabolite pathways associated with antioxidant and increases plant secondary metabolites. Thus, it can be widely used in agriculture to increase production and product quality.

PERFORMANCE AND RESOURCE OPTIMIZATION OF DIRECT SEEDED TECHNOLOGY WITH SEED CUM FERTI DRILL IN RICE

Paper ID- AMA-13-09-2022-11672

Direct seeded rice (DSR) is a feasible alternative to conventional puddled transplanted rice with good potential to save water, reduce labour requirement, mitigate green-house gas (GHG) emission and adapt to climatic risks. Paddy is major predominant crop during Kharif in erstwhile Nalgonda district of Telangana, cultivated in an area of 3,95,090 ha, out of total cropped area of 6,87,966ha with productivity of 2664 kg/ha. Production of conventional puddled transplanted rice is facing severe constraints because of water and labour scarcity and climatic changes. The yields are comparable with transplanted rice if crop is properly managed. In 2019 to 2021, efforts have been made in promoting the DSR technology in Nalgonda with collaboration with Reddy’s foundation under Corporate Social responsibility by Krishi Vigyan Kendra, Kampasagar of PJTSAU university. Direct sowing of Rice with Seed cum Ferti Drill is boon to farmers to save money, time, water and crop comes to harvest 7-10 days earlier than normal transplanted paddy. KVK, Kampasagar, Nalgonda extension centre has organized Frontline Demonstrations (FLDs) in farmer fields in two seasons Kharif, 2020 and Kharif, 2021. Direct sowing of Rice with Ferti Cum Seed Drill recorded 12.90 % more grain yield over normal transplanting method of paddy cultivation during both Kharif seasons. The results from the present study showed that farmers realized 53.0% increase in net income due to increased grain yield by 12.90% with reduction of cost of cultivation by 31.80%, it could be attributed to reduction in manual labour of 6man labour and 30 women labour and also increase in yield attributes and yield.

Estimation of Gene effects through Generation Mean Analysis and Validation of known markers associated with Zn content in rice through Bulked Segregant Analysis

Paper ID- AMA-13-09-2022-11671

Generation mean analysis investigation in rice was carried out to assess the gene action operating in the inheritance of yield, its components, and quality traits. Five basic generations viz., P1, P2, F1, F2, and F3 of three crosses, namely IET-25475 x IET-25477(Cross-I), GNR-7 x GNR-3 (Cross-II), and GAR-13 x IET-25477 (Cross-III) were studied. A scaling test was applied to test the adequacy of the additive-dominance model for the traits under investigation. The result of individual scaling tests C and D revealed that the additive-dominance model was found inadequate for the description of variation in generation mean for all the eleven traits of all three crosses. Based on five parameter model, the main effects viz., mean (m), additive (d), and dominance (h) and two digenic interactions, additive x additive (i) and dominance x dominance (l) were significant for days to flowering in cross-I; for productive tillers per plant in cross-I and cross-III; for grains per panicle and 100-grain weight in cross-II; for grain yield per plant in cross-II and cross-III; for straw yield per plant and amylose content in cross-I and cross-II and days to maturity, plant height, L: B ratio and Zn content in all crosses indicated that involvement of additive, dominance as well as epistasis interaction for controlling this trait. BSA was carried out to identify markers linked to Zn content using 235 plants from F2 segregating generation of GAR-13/IET-25477, two indica ecotypes with extreme Zn content. The parents were screened for polymorphism using fifty rice microsatellite primer pairs. Out of 50 SSR primers, only two were found able to discriminate both the parents (HIGH Zn content and low Zn content) sufficiently. Two markers (RM 21 and RM 248) were identified as linked to the Zn content gene through BSA.
