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.
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.
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.
The study aims at finding the extent of farmers knowledge about happy seeder technology of wheat sowing in standing paddy stubbles and correlation with their personal attributes, was conducted in Ambala & Kurukshetra district of Haryana state with the sample of 160 respondents of twenty villages. As per results, however, majority of the farmers were belonged to full and partial level of knowledge about some Aspects/Items (Those were related to benefits of happy seeder and suitable type of tractor for operating it), out of Thirteen Aspects/Items, selected and listed in interview schedule for the study, such as Happy seeder is a time and fuel-saving technology, Happy seeder technology is an Eco-friendly technology, Happy seeder improves soil health and, Compatible tractor type and its HP for operating the machine. But, even that, they had little knowledge about the remaining Aspects/Items, Therefore, their overall knowledge about the HS was less, in fact, the majority of farmers possessed a low level of expertise about Happy seeder technology as a whole. So, most of the respondents were belonged to low level category of Overall knowledge towards Happy Seeder Technology. In case of personal traits, it was found that those attributes which had taken in the study, were found to have positively correlated but only one trait i.e. age was negatively correlated with knowledge level of farmers.
Field experiments were carried out to study the effect of nanofertilzers on yield attributing characters and yield of okra (Abelmoschus esculentus L.) at the Agriculture Research Station, Binjhagiri, Chatabara, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar, during February 2021-May 2021. The experiments were laid out in Randomized Block Design with three replications and fifteen treatments viz., Control (only FYM) T1,75% RDF (Conventional fertilizer in soil) T2, 100% RDF (Conventional fertilizer in soil) T3,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T4,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T5,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T6,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T7,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T8,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T9,75% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T10,75% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T11,75% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T12,100% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T13,100% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T14, 100% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T15. The present study revealed that the maximum plant height (107.41 cm), was obtained with T3 +IFFCO Nano N(Foliar sprays @ 3 ml/litre), whereas maximum fruit length (14.26 cm) and maximum fruit weight(16g) was obtained with T3 + Geolife NPK(19:19:19) @2g/l. The maximum yield per plant (193.93 g) was recorded with T2 +IFFCO Nano N (Foliar sprays @ 4 ml/l).
