A total of 90 groundwater samples spread across three taluks of Yadagir district were collected during pre-monsoon season, 2018 and analyzed for physico-chemical parameters and irrigation quality parameters like sodium absorption ratio (SAR), Percent sodium (%Na) and residual sodium carbonate (RSC) were calculated to assess groundwater suitability for irrigation purpose. It was evident from the results that 8.82, 60 and 87.1 % of samples respectively in Yadagir, Shahapur and Shorapur taluks were recorded the pH values above the BIS standard limit of 6.5-8.5. Higher alkaline pH values prevailing in majority of groundwater samples from the study area is due to higher alkalinity and bicarbonate concentration. Electrical conductivity values in 35.29, 28 and 35.48 % of samples respectively in Yadagir, Shahapur and Shorapur taluks witnessed the higher values above 2000 µS/cm, while 97, 84 and 70.96 % samples respectively in the above taluks showed higher TDS values above BIS desirable limit of 500 mg/L. Overall quality of 32.22 % of groundwater samples from Yadagir district is classified as good water (50>WQI<100) based on WQI values and are considered as suitable for domestic and irrigation purpose. Rest of the samples were considered as unsuitable for domestic and irrigation purpose, attributed to higher salinity, total hardness, fluoride, TDS values, etc.
Curriculum is the central part of agricultural education in offering qualitative education in this country. Therefore, it is mandatory for colleges or agricultural universities to take up curriculum development to build strong human resource and overall personality development of graduates in this country in the years to come. Hence, an attempt was made to know the perception of teachers towards agricultural curriculum in a state agriculture university (SAU). The study was conducted at University of Agricultural Sciences (UAS), GKVK, Bangalore during 2010-11 and the sample consisted of 60 teachers was selected by using simple random sampling method. A well structured, pre-tested questionnaire was used to collect the data and the data were analyzed using appropriate statistical techniques. The results revealed that 43.33 per cent of the teachers opined that curriculum was useful, whereas 31.67 per cent was more useful and 25 per cent was less useful, respectively and 78.33 per cent of teachers had opined that horticulture discipline was more useful in acquisition of knowledge, 58.33 per cent of students had expressed Agricultural engineering discipline was useful in developing skills and 23.33 per cent of students reported that Plant Protection discipline was less useful in overall personality development of students. This calls for the need for assessing the pedagogy of teachinglearning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
