Soil samples were taken from different depths (viz. 0-15, 15-30, 30-45, 45-60, and 60-90 cm) of the wheat field under irrigated saline regimes ranging from 1.5 to 12 dSm-1. The relationship between the electrical conductivity of saturated paste extract (ECe) and soil-water suspension extracts (i.e., EC1:2 and EC1:5) was established beside the development of regression models and conversion factors. Regression models relating ECe with EC1:2, EC1:5 were developed with coefficients of determination (R2) 0.98 and 0.99 respectively. The average conversion factor between ECe~ EC1:2 and ECe~ EC1:5  were 2.7 and 7.7, respectively. Methods standardized in the study can be used to estimate the EC of different saturated soil paste extract ratios, which will be less cumbersome and significantly reduce the estimation time. ","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85337510","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}

There was a demand for mechanisation for harvesting the tuber because the conventional method of harvesting followed was tedious and time-consuming. For the design and development of a coleus harvester with reduced drudgery, the design parameters were selected with respect to the tuber properties. Random sampling was carried out for determining the physical and frictional properties of coleus. The average values of physical properties such as length, width, thickness, geometric mean diameter, sphericity, surface area, volume and bulk density were found out as 44.56 mm, 27.36 mm, 24.50 mm, 30.99 mm, 0.70, 3029.69 mm2, 15786.50 mm3 and 718.21 kg m-3 respectively. The angle of repose was determined as 30.83° and the coefficient of static friction was found out as 0.73, 0.69 and 0.81 on galvanised iron, stainless steel and plywood surfaces respectively. These data were used for the design of various components of the harvester.","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84734227","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}

In India, agricultural production has been transformed into a multifaceted business enterprise. Indian agriculture to remain competitive needs the accumulation and integration of scientific knowledge, and information from many diverse sources.  Indian farmer often relies on agricultural specialists, advisors and agricultural research and development institutes for agricultural information for better decision making at the actual farm situation. Unfortunately, timely specialist assistance is not available when the farmer needs. Thus the situation demand for a ‘virtual expert’ who can give personalized expert advice to a large community of farmers, specific to their needs and aspirations considering various knowledge sources. The role of expert systems in tobacco sector and its applications in effective production and protection technologies have been discussed in this article. It is almost impossible for any human expert to consider every piece of available information before arriving at optimal decisions. To overcome this problem and provide precise information to the farmers, “expert systems” have been developed with a primary goal to make expertise available to clients and decision makers who need answers swiftly. The main aim is to deliver the required information and disseminate the up-to-date scientific knowledge in a readily accessible and easily understood form to the farmers. It is one of the most efficient extension tools to take the technology from scientists to the growers directly without any distortion of content which normally creeps in because of multiple agencies involved in conventional technology transfer systems. With this aim, ICAR-Central Tobacco Research Institute has developed a web-based expert system on tobacco using “Agridaksh”- an online tool developed by ICAR-Indian Agricultural Statistics Research Institute. This, online expert systems has the tremendous capacity to transfer location specific technologies and advice to the farmers with a greater precision","PeriodicalId":14972,"journal":{"name":"Journal of AgriSearch","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76640718","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}
