Methods: The investigation was conducted to assess the impact of integrated nutrient management on the growth and yield performance of direct seeded rice in dyrtrudepts of Nagaland at the experimental farm of the School of Agricultural Sciences (SAS), Medziphema Campus, Nagaland University, during kharif season of 2019 and 2020.

Methods: The kite sustainability assessment is a multi-objective assessment method based on standardized scoring formulas built on land assessment criteria with limiting factors. It used the AHP method to determine how different critical factors affect whether a place is good for growing rice. The soil fertility, economics, and social factors were also significant in determining whether or not rice could grow there and how well it might do. Results: The soil fertility status of the two main rice cropping in the study area has low pH, high organic matter content, high cation exchange capacity, and high clay content. Besides, the soil has a good water-holding capacity, high total N content, and average total P content. Utilizing the AHP method, it was determined that soil fertility, economic, and social factors were the second-most significant factors in determining the suitability of land for agriculture as well as the possibility and performance of rice. While the double-rice cropping model is only sustainable regarding fertility, the triple-rice cropping model achieves the sustainability goal of economic, social, and soil fertility indicators. Two rice cropping seasons, lWS-mSA (double rice) and mWS-eSA-eAW (triple rice), achieve a balanced level in all indicators of level 2 of soil fertility. Therefore, in both models, a system that reaches a sustainable level exists. Even so, the lWS-mSA cropping season could be less harmful to the environment than the mWS-eSA-eAW season in terms of the environmental group.\u0000","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46361850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, therefore, aimed to evaluate the effects of electrolytes and soil-to-suspension ratios on soil pH and to optimise pH measurement methods for acidic-coarsely textured soil. Methods: Varied standard electrolytes (water, 0.01 M CaCl2 and 1 M KCl) and soil-to-suspension ratios (1:1, 1:2.5 and 1:5 w/v) were used to measure the pH of thirty samples of acidic-coarsest textured soil. Result: Soil pH values were observed in the following order: water greater than 0.01 M CaCl2 greater than 1 M KCI. Higher soil pHs were a result of higher suspension volumes. The most optimal pH measurement method for an acidic-coarsely textured soil was obtained from the 1:2.5 soil-to-suspension ratio of 1 M KCl, which held the highest R2 (0.850), as well as the lowest root mean square error (RMSE) (0.010), indicating the most precise method. An alternative method suitable for a cost-saving laboratory was the 1:1 soil-to-suspension ratio of 0.01 M CaCl2, which owned R2 of 0.766 and RMSE of 0.013, as its pH measurement was similar to those under the most optimal method.","PeriodicalId":13398,"journal":{"name":"Indian Journal Of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48917047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
