Food production in cities has long been a tradition in many countries around the world and a mainstream agricultural activity for many developed countries. Demand for local food, including strawberries (Fragaria ananassa L.), is gaining popularity globally due to its richness in vitamins, nutraceuticals and flavour. Farmers, growing strawberry under protected structure mostly prefers the horizontal methods (viz., cultivate on the soil as a single bed system) in India. The present investigation was carried out at Junagadh Agricultural University, Junagadh (Gujarat) during 2019-20 and 2020-21. The experiment was laid out in Completely Randomized Design, consisting four treatments each replicated four times. The triple layer system (T3) performed better in case of plant height (17.16 cm), canopy spread (29.06 cm), and number of leaves per plant (17.99). The number of flowers per plant (23.38) was significantly higher in the single layer system (T1) in contrast, higher marketable fruit (96.48%) was evident in the triple layer system (T3). Fruit weight was non-significant among the treatments. The single layer system (T1) exhibited maximum yield per plant (286.13 g), while the four layer system (T4) has shown maximum yield per acre (7734.63 kg). Acute variations with regards to the environmental parameters; temperature, relative humidity and irradiation attributed to differential growth and productivity in strawberry under different production systems. Based on the results obtained from the present investigation, it can be comprehended that the triple layer system (T3) of vertical garden could be considered for adaptation under the semiautomated protected structure for maximizing the productivity in strawberry cv. Winter Down.

Genotypic and Phenotypic Correlation Coefficient Studies in French bean (Phaseolus vulgaris L.)

Paper ID- AMA-09-11-2022-11798

Thirty-one French bean genotypes (Phaseolus vulgaris L.) including 22 genotypes obtained from NBPGR, New Delhi, six genoytpes collected from lower Pulne hills of Western Ghats and three released varieties viz., TKD 1, Arka Sukomal and Sonali were evaluated in Randomized Complete Block Design (RCBD) with three replications during 2020-2022 at Horticultural Research Station, Tamil Nadu Agricultural University, Thadiyankudisai, Tamil Nadu. Genotypic and phenotypic correlation studies for nine characters were assessed for association between different characters, direct and indirect effects of component traits on pod yield and other horticultural traits viz., days to first flowering, days to 50% flowering, pod length (cm), pod girth (cm), number of pods per plant, pod weight (g), yield per plant (g), yield per plot (kg), yield per hectare (t) of French bean. The results revealed that days to first flowering and days to 50% flowering had associated negatively and significantly with pod yield. The other traits viz., pod length, pod girth, number of pods per plant and pod weight showed positive and significant correlation with pod yield in French bean.

Study on Soil Properties of Different Tree based Land use Systems in Eastern and South Eastern Coastal Plain Zone of Odisha

Paper ID- AMA-07-11-2022-11795

In the present investigation, an attempt has been made to study the effect of land use systems on soil physical, chemical and biological properties in eastern and south-eastern coastal plain zone of Odisha. We have employed Completely Randomized Design (CRD) technique over eight land use systems to analyze different soil properties of soil viz. MBC, MBN, SBP, SFP, SOC, BD, PD, EC, PH. It has been found from the analysis that the MBC, MBN, soil bacterial and fungal population is the higher in natural forest than other tree based land use systems. The bulk density, particle density, pH and EC of soils in different tree based land use systems are negatively correlated with microbial properties of soil but water holding capacity, soil organic carbon and available nitrogen is positively correlated with microbial properties of soil in different tree based land use systems. Among the tree based land use systems homestead agro forestry and teak plantation recorded physico-chemical and microbial properties comparable with natural forest and better than agricultural rice lands. It is found from the study that the land use homestead agro-forestry and teak plantation are recommended in the coastal area of Odisha for soil health improvement and sustainable production.

Optimization of incident solar radiation for microgreens cultivation under simulated agriphotovoltaics

Paper ID- AMA-07-11-2022-11794

Under agriphotovoltaics and/or in shade net house, plants fail to perform well under reduced solar radiation. Controlled growing systems using artificial LED lights can be considered to increase productivity in those areas. In this study, spinach was grown in hydroponics under 8 combinations of sunlight and cool white LED light at night (T1: 100% sunlight (SL), T2: ≈75% SL), T3: ≈50% SL, T4: ≈25% SL, T5: ≈75% SL + ≈25% LED, T6: ≈50% SL + ≈50% LED, T7: ≈25% SL + ≈75 % LED, and T8: ≈100 % LED) as treatments to know the effects of LED and reduced sunlight on its different morpho-physiological attributes and also to optimize lighting conditions for productive and profitable spinach cultivation under simulated agriphotovoltaics. Observations taken on 15, 30 and 45 days after germination revealed that values of all the parameters except leaf nitrate content got reduced with the reduction in the solar availability. Use of white LED lights with lower solar irradiance has helped plants to overcome the stress condition up to some extent by improving their growth attributes, however, its 100% use could not help much due to marginal intensity of red band in it. Overall, T1 has come up with the best results followed by T5, T6, T2, T3, T7 and T4, while T8 least performed. The present finding envisaged that cool white LED lights may be a good replacement for solar light. However, these could be replaced with grow lights with wider wavelength range to get higher productivity and profitability.

Developing Hapten Conjugates For Imidacloprid Immunoassay

Paper ID- AMA-07-11-2022-11793

Pesticide residues are determined using sophisticated equipment such as UHPLC, LCMS, GC, and GCMS, which necessitate high operating costs, a controlled atmosphere for instrument housing, and technical personnel for handling. The field of immunoassay has made it possible to determine pesticide residues in food products in situ without the assistance of technical personnel. In order to establish an immunoassay approach, it is necessary to synthesize hapten and conjugate it with a carrier protein for generating an immunological response in any animal system. Therefore, the method for synthesizing imidacloprid hapten and the covalent linkage with carrier proteins such as Bovine Serum Albumin (BSA) were explored in this work. Thin-layer chromatography analysis of synthesized hapten revealed that its Rf value was distinct from that of the imidacloprid standard (0.98) and hapten (0.2). The production of imidacloprid hapten was subsequently confirmed by LCMS and 1HNMR. The generated hapten was conjugated with BSA using the active carboxyl ester technique for further use as an antigen.
