No full textA field experiment was conducted during Kharif 2017 and 2018 to study the effect of organic and inorganic sources of nutrients on SVI, weed competitiveness and root characteristics of aerobic rice with Integrated Nutrient Management in Aerobic rice. The experiment was laid out in split plot design with four organic sources of nutrients as main plots viz: M1: Neem leaf manure @ 6 t ha-1; M2: Vermicompost @ 2 t ha-1; M3: Goat manure @ 5 t ha-1; M4: Microbial consortia seed treatment @ 4g kg-1 + soil application @ 4 kg ha and four subplots with graded doses of fertilizers viz; S1: Control; S2: 50% RDF; S37: 5% RDF and S4:100% RDF (120-60-40). The study revealed that inorganic nutrient level of100% RDF exhibited a significantly superior Seedling Vigor Index (15.8) and lowest (13.1) was observed with control i.e.,0% RDF while organic nutrient source i.e., Neem leaf manure applied as a mulch, suppressed weed emergence resulted in lower weed population (3.7 no.m-2) and weed dry biomass (2.9 g). Both organic nutrient sources and inorganic nutrient levels exerted a remarkable effect on root traits viz; root length, root biomass, root volume. Application of M2 (vermicompost @ 2 t ha-1 ) orM3 (goat manure @ 5 t ha-1 ) and fertilizer dose of 100% RDF (120-60-40) resulted in higher root length, root biomass,root volume and root-shoot ratio

No full textNot AvailableLead sinkers are a popular choice among fishers due to their affordability, ease of manufacture, density, and chemical stability. However, their widespread use has contributed to environmental pollution, particularly in marine ecosystems, resulting from leaching, abrasion, and degradation. The present study aims to address lead contamination from fishing sinkers in the marine environment by utilizing nano silicon dioxide-reinforced bisphenol. A epoxy polymeric coating on the lead and assessing the coating’s resistance to corrosion. The reinforcement of SiO2 was confirmed through UV-Vis spectroscopy and FTIR, demonstrating the SiO2 interacting with the benzene moiety of the bisphenol A epoxy resin. The SiO2 was uniformly distributed in the epoxy resin, resulting in a pore free and a smoother surface. Electrochemical evaluation showed that 0.5% SiO2 reinforcement in epoxy resin was optimal for enhancing corrosion inhibition. The abrasion resistance of lead coated with nano SiO2 epoxy resin exhibited efficiencies of 50.18% and 88.71%, respectively, with SiO2-epoxy coating thicknesses of 0.011 mm and 0.033 mm, compared to the untreated control. The potential impact of these results on the marine environment could be significant, as they may provide a more environmentally friendly and economical option for fishers who rely on lead sinkers.Not Availabl

No full textNot AvailableThe investigation was carried out during the fruit pruning season 2022-23 on 6-year-old vine of
Crimson Seedless at ICAR- National Research Centre for Grapes, Pune. The vines were grafted on four
different rootstocks (Dogridge, 110R, 140Ru and 1103P). The vines grafted on Dogridge rootstock
recorded high TSS, lowest acidity and high TSS: Acidity ratio. 110R rootstocks had lowest berry
firmness and skin thickness. 110R rootstock showed better results in organoleptic quality such as color,
sweetness, taste, mouthfeel, flavor and overall acceptability as compared to other rootstocks.
Rootstocks 110R recorded lowest rate of rachis dehydration and minimum physiological weight loss
from bunches on different days of the shelf life. The vine grafted on Dogridge and 140Ru grafted vines
recorded least rotten berries while 140Ru had the lowest number of fallen berries during shelf life. In
conclusion, Crimson Seedless vines on 110R rootstock enhance shelf life and sensory quality of grapes,
but terms of fresh grape quality Dogridge show better results.Not Availabl

No full textNot AvailableThe experiment was carried out for three at the farm of ICAR- National Research Centre for Grapes,
Pune. The experiment was conducted in randomized block design with three replications. The vines
were trained on ‘mini-Y’ trellis system and spacing of 2.4×3 m2
. Four-year-old vines of these varieties
were selected for the study. The growth parameters like pruning weight and shoot diameter was
recorded in variety Cabernet Sauvignon and Syrah while Niellucio observed highest leaf area and shoot
length. The early days to bud sprout and days to harvest was recorded in variety Cabernet Franc and
Grenache. The number of bunches/vine and yield/vine were varied significantly among the varieties
with number of bunches/vine and yield/vine highest in variety Syrah. But bunch weight and number of
berries/bunch was highest in variety Tempranillo. However, different varieties of grape exhibited
significant variation with respect to average hundred berries weight. The hundred berries weight was
highest in Cinsaut. The varieties Grenache gave the highest total soluble solids and lowest acidity in
Tempranillo while maximum juice recovery was observed in variety Cinsaut. Volatile acid and total
acid content highest was recorded from variety Grenache and Cabernet Sauvignon as compared to other
cultivars. In wine quality parameters, variety Tempranillo recorded highest wine pH while Petit Verdot
and Cabernet Franc showed highest malic acid and volatile acid.Not Availabl

2023 to investigate the impact of different rootstocks on the growth, photosynthetic activity, petiole nutrient
content, yield, and quality of Manjari Naveen grape. It was observed that grapevine rootstocks are essential
for the overall productivity and quality of grapes. Manjari Naveen grapes grafted on Dogridge (Vitis vinifera
L.) rootstock exhibited good fruitfulness. Dogridge rootstocks produced the highest yield and grape quality.
However, 110R rootstock demonstrated high TSS. There was no significant influence on the uptake of nitrogen,
phosphorus, and potassium among different rootstocks. Additionally, 140Ru rootstock was observed with
higher photosynthetic activity compared to the other rootstocks.Not Availabl

No full textNot AvailablePrecise application of nitrogenous fertilizers mainly urea ammonium nitrate (UAN) and granular urea (both pure and
neem-coated) in aqueous form, is critically important for basal and foliar applications. The physicochemical properties
of aqueous solution of these nitrogenous fertilizers plays important role in design of any liquid fertilizer application
system. The study was carried out during 2019–20 at ICAR-Indian Agricultural Research Institute, New Delhi with
an aim to develop algorithms for use in sensors-based systems for real time monitoring of available N concentration
in the fertilizer solution before its application. The physicochemical properties like pH, electrical conductivity (EC),
specific gravity (SG), dynamic viscosity (DV), surface tension (ST) and percentage light absorbance (LA) of urea
ammonium nitrate (UAN-28%), pure urea, and neem coated urea in diluted form (pre-selected N-concentrations i.e.
0.78, 0.9, 1.08, 1.33, 1.75, 2.54 and 4.67% corresponding to the dilution ratios of 1:35, 1:30, 1:25, 1:20, 1:15, 1:10
and 1:05) were measured and analyzed for their significance with N-concentration. Electrical conductivity (EC)
alone showed a significant relationship with N-concentrations. Prediction models were developed for diluted UAN
and granular urea fertilizers based on the EC and N-concentrations. The regression models in terms of EC to predict
N-concentration had coefficients of determination (R2) of 0.998, 0.998, and 0.999 for diluted UAN, pure urea, and neem
coated urea with water, respectively showed a great potential for their sensor based precise application. The controlled
application of diluted liquid fertilizers with water can be achieved through sensing relevant physicochemical property.Not Availabl

No full textNot AvailableDue to the increasing complexity of agricultural challenges faced by Indian farmers, there is a critical need for data driven insights to tailor extension services, enhance productivity, and ensure sustainable farming practices. In this scenario, understanding farmers' information demands can significantly improve support mechanisms and policy interventions. With this aim in focus, the present study leverages the Kisan Call Center (KCC) dataset to analyze the information demands of Indian farmers regarding three key edible oil crops: groundnut, mustard, and soybean. By examining the queries received from farmers, the research identifies significant patterns and trends in agricultural challenges and practices across different states and over multiple years. The study categorises these queries into types such as agronomic practices, pest management, market information and more. Key findings reveal notable geographical variations in query volumes, underscoring the need for localized agricultural extension services. Based on these insights, the study proposes actionable policy recommendations to enhance plant protection services, improve weather forecasting and advisory services, promote advanced crop varieties, and disseminate market information more effectively. These recommendations aim to address the specific needs of farmers, thereby supporting informed decision making, boosting productivity, and enhancing livelihoods. Future research is recommended to monitor the evolving information demands of farmers and to refine extension services accordingly.Not Availabl
