Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    STUDIES ON INFLUENCE OF CROPPING SYSTEMS ON SOIL PROPERTIES
    (CSKHPKV. Palampur, 2019-07-22) DHIMAN, SHUBHAM; Datt, Naveen
    A field experiment was conducted during the years 2017-18 at Bhadiarkhar farm, Department of Agronomy, Forages and Grassland Management, CSKHPKV, Palampur to evaluate effect of eight cropping systems viz. rice-wheat, rice-peasummer squash, okra-radish-onion, turmeric-pea-summer squash, rice-lettucepotato+coriander, rice-palak-cucumber, rice-broccoli-radish and colocasiapea+coriander on various soil properties and productivity. The experiment was laid out in randomized block design and was replicated four times. The soil of experiment site was silty clay loam in texture, acidic in reaction (5.3), medium in available nitrogen (362.4 kg ha-1), high in available phosphorus (73.6 kg ha-1) and medium in available potassium (115.2 kg ha-1). Study of one year revealed that rice-pea-summer squash resulted in higher microbial population, microbial biomass carbon and dehydrogenase activity. Higher available K and lower bulk density were recorded in turmeric-pea-summer squash. Colocasia-pea+coriander resulted in higher available N and DTPA-Fe. Better available phosphorus and phosphatase activity were recorded in rice-palak-cucumber. Rice-palak-cucumber cropping system resulted in the highest rice grain equivalent yield (16,477 kg ha-1) compared to the traditional rice-wheat system. Maximum returns (Rs 2,19,828), benefit cost ratio (1.76) and productivity (63.6 kg ha-1 day-1) were also recorded from this system. The yield was significantly and positively correlated with available nitrogen, DTPA-Fe, microbial population, microbial biomass carbon and dehydrogenase activity. Therefore, farmers should substitute existing rice-wheat cropping system with rice-based vegetable systems for improved soil properties, productivity and returns.
