Impact of enriched biocompost application in integration with chemical fertilizers on soil fertility and productivity of rice crop in rice-wheat system

Paper ID- AMA-19-05-2022-11391

A two year field experiment on rice crop was conducted on sandy loam soil at Crop Research Centre of SardarVallabhbhai Patel University of Agriculture and Technology, Meerut, during 2009 and 2010 to evaluate the impact of enriched biocompost application in integration with chemical fertilizers on soil fertility and productivity of rice crop in rice-wheat system. Growth parameters, yield attributing characters, grain and straw yield of rice crop was affected significantly by different treatments. Nutrient assimilation at different stages by rice crop also varied significantly due to application of different treatments in the study. Rice grain yield increased significantly due to application of additional 25 % NPK over 100 %. Growth parameters and yield attributing characters, improved slightly due to application of biocompost. Application of higher levels of biocompost along with 75 % NPK produced significantly higher grain yield of rice than T2. No significant effect of biocompost enrichment of biocompost was found although slightly higher grain yield of rice was found with the application of enriched biocompost than unenriched at particular NPK level. Micro nutrient contents of both the crops were slightly higher due biocompost application. Availability of primary macro nutrients was slightly higher in the plots receiving super optimal application of NPK or higher biocompost levels.

Perceived Impediments faced by farmers’ vis-à-vis adoption of Zero tillage machine in Indo-Gangetic plain of India: PCA based Construct Validation

Paper ID- AMA-19-05-2022-11390

Due to increased global warming, world is witnessing the climate change. It is a major threat for declined agricultural productivity. Zero tillage is a sort of Conservation Agriculture practices, can contribute to sustain production and improve the farmers' economy. Rice and Wheat are the world's highest producing and consuming food grains. A short decline in rice–wheat productivity may unease the food security of the world. Rice–Wheat cropping system is a chief cropping system of Indo-Gangetic plain of India. The present study was conducted in West Champaran district of Bihar under the Climate Resilient Agriculture Programme of RPCAU, Pusa. The programme emphasizes the adoption of zero tillage and other Conservation Agriculture practices/Climate Resilient Agriculture practices. Farmers faced various perceived impediments in the adoption of Zero tillage machines. PCA was used to validate the impediments statements considering KMO Sampling Adequacy along with Bartlett's test of Sphericity. There were 24 impediments which were further grouped into four different broad impediments, i.e., production, technical, 'socio-economic, and psychological impediments, and extension impediments. Among the twenty-four impediments, 'non-availability or limited availability of zero tillage machines' was a ubiquitous constraint and consequently, it was dropped as its extraction value was 0.19. The Friedman test value was found to be significant at a 1% level (p<0.01) and the value of the chi-square test was 304.919 with 3 degrees of freedom. Therefore, it can be concluded that there was significant variation between four different broad groups of impediments perceived by the farmers. In Friedman's comparative mean ranking, lesser the mean score better is its rank. Friedman mean score for 4 broad impediments were extension impediments (1.05), technical impediments (2.47), socio-economic and psychological impediments (2.57) and production impediments (3.92) and thus ranked as 1st, 2nd, 3rd and 4th respectively. Hence, it can be interpreted that out of four broad impediments, 'extension impediments' were found most pertinent over the others for less adoption Zero tillage machine.

Effect of organic inputs on nutrient status and quality of high density guava under organic management in north western plains of India

Paper ID- AMA-19-05-2022-11388

Organic farming in guava has opened a new vista for sustainable crop production under this covid pandemic situation where every human being is moving forward for healthy and chemical free fruit production. For keeping the safety rules for human health an experiment was conducted to study the impact of different organic manures solely or in combinations with biofertilizers on fruit quality and relative economics of high density guava during winter season in the experimental farm at Organic Farming Research Centre (OFRC), Chatha at Sher-e-Kashmir University of Agricultural Sciences & Technology, Jammu (J&K). The experiment was conducted on three years old guava trees with 13 treatments alone or in combinations with vermicompost and poultry manure and biofertilizers (Azotobacter and PSB) during the first week of July. The results of the experiment revealed that highest organic carbon (7.6 g kg-1), water holding capacity (52.10 %), soil microbial biomass(97.98 mg kg-1) and lowest bulk density (0.29 g cm-3) were recorded from the with the application of farmyard manure (25%) + vermicompost (50%) + poultry manure (25%) (T12) whereas, highest leaf N, P & K (1.73, 0.23 & 1.28 %) content were obtained with the treatment comprising of full dose of N through PM + Azotobacter + PSB (T9). The same treatment (T9) also recorded highest leaf chlorophyll content to the corresponding value of 9.96 mg g-1 tissue. The data also revealed that full dose of N through poultry manure + Azotobacter+ PSB (T9) recorded highest fruit TSS, pectin, vitamin C and total sugar. It was found that full dose of N through poultry manure+ Azotobacter+ PSB (T9) was considered as best treatment with the maximum profit of Rs. 6,52,888 and benefit cost ratio of 1: 5.26.

Evaluation of seed quality in artificial aged seeds (accelerated ageing techniques) of Chickpea during invigoration

Paper ID- AMA-18-05-2022-11386

The laboratory trial was conducted in the State Seed Testing Laboratory during rabi season 2018, to normalize the best treatment of plant development controller with preparing explicit to Chickpea (Pusa-362). Initially, Relative humidity (90% RH), distinctive temperature (350 and 400 C), Days (2,4 days) are utilized for seed aging after that utilized hormonal preparing viz; gibberellic acid (GA3) and salicylic acid (SA), to improve germination and seedling characters. Two plant growth regulators, GA3 and SA with control (untreated) were assessed by screening 12 hrs hour and 100 ppm fixation. In this trial utilized various conditions viz; T1-Temperature (350C), T2-Temperature (400C), H1 - Humidity (90% RH), D1-Duration (2 Days), D2-Duration (2 Days), P1-Gibberllic Acid, P2-Salicylic Acid, with various treatments viz; To - control (untreated), T1 - H1T1D1, T2 - H1T1D2, T3 - H1T2D1, T4 - H1T2D2, T5 - P1H1T1D1, T6 - P1H1T1D2, T7 - P1H1T2D1, T8 - P1H1T2D2, T9 - P2H1T1D1, T10 - P2H1T1D2, T11 - P2H1T2D1, T12 - P2H1T2D2. It was demonstrated that all the treatment indicated significant differences with the control and the most elevated germination percent, seedling length, seedling fresh weight, seedling dry weight, Vigour index were estimated for (GA3) T5 - P1H1T1D1. Pre-sowing treatment with PGRs effective on aged seeds, its straight forwardness and hormones could be utilized as a basic technique to identified with a helpless germination and seedling foundation and aides in continuing farming and financially low expense and monetary, non-poisonous, eco-friendly sources.

Agronomic responses and molecular breeding approaches towards elevated ozone in rice

Paper ID- AMA-17-05-2022-11384

Rice (Oryza sativa L.) is one of the most important staple food crop cultivated in South East Asia fulfilling the dietary needs of the people. This crop is being influenced by a variety of abiotic and biotic factors contributing to a change in its physiology, biochemistry as well as its genetics. Abiotic factors including oxides of nitrogen, carbon and an array of volatile organic compounds react with UV radiation leading to the generation of ozone in the troposphere. The ozone influence on rice has caused a lot of concern among the rice scientists and has necessitated the development of strategies to combat the problem. Molecular biology approaches including marker assisted selection involving QTLs linked to genes conferring tolerance to ozone stress have been identified due to the recent breakthroughs in rice genomics. Many medium-effect loci instead of single large-effect loci are supposed to govern the trait. The present review is an approach to provide information on the physiological, biochemical and molecular responses of rice towards elevated ozone tolerance and also reflect the available strategies to minimize the effect.
