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.

    EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON YIELD, QUALITY AND SOIL PROPERTIES IN PEA - OKRA SYSTEM IN AN ACID ALFISOL
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2012) DHIMAN, SUSHIL; Dixit, S.P.
    The present investigation was carried out to study the effect of integrated nutrient supply on yield, quality and soil properties in pea-okra system in a field experiment conducted from rabi 2008-09 to kharif 2011 at the Experimental Farm of Department of Soil Science, COA, CSK HPKV, Palampur in a randomized block design with thirteen treatments replicated three times. The soil of the experimental site was silty clay loam and classified taxonomically as “Typic Hapludalf” with acidic reaction, medium in organic carbon, low in available N, medium in P and K at the initiation of the experiment. The treatments were control, 75, 100 and 125 % NPK alone, along with lime, vermicompost @ 5 and 10 t ha-1. The results revealed that addition of 125% NPK with 10 t vermicompost ha-1 recorded highest pod/fruit yield of pea and okra during all the years as compared to rest of the treatments. Amongst the rate of vermicompost application, 10 t ha-1 proved better over 5 t ha-1 at 75, 100 and 125% levels of NPK. Lime application with graded doses of fertilizers viz. 75, 100 and 125% NPK also increased the yield of both the crops over 75, 100 and 125% NPK alone as well as control. Uptake of N, P, K, Ca, Mg, Fe, Cu, Zn and Mn by both the crops during all the years followed almost similar trend as that of their respective yields. Crude fibre and chlorophyll content in okra fruit and crude protein, total soluble solids, ascorbic acid, carbohydrate, reducing, non-reducing and total sugars in pea seed increased in treatments where 75, 100 and 125% NPK with either lime or vermicompost @ 5 t ha-1 or 10 t ha-1 was applied as compared to 75, 100 and 125% NPK alone. There was build up of organic carbon, available N, P, K and exchangeable Ca and Mg due to lime or vermicompost application @ 5 and 10 t ha-1 along with 75, 100 and 125% NPK over 75, 100 and 125% NPK alone. A decrease in the DTPA extractable Fe, Mn, Zn and Cu, different forms of soil acidities and Al and Fe was recorded in 75, 100 and 125% NPK with lime over 75, 100 and 125% NPK alone. However, application of vermicompost @ 5 and 10 t ha-1 at their respective levels of NPK increased the different DTPA extractable micronutrients, pH and decreased the different soil acidities as well as Al and Fe. Benefit cost ratio was highest in 125% NPK followed by 100% NPK in pea and 125% NPK + lime followed by 100% NPK+ lime in okra. The highest net returns in (Rs.51705 ha-1) were obtained in 125 % NPK + vermicompost @ 5 t ha-1 in pea and (Rs. 33239 ha-1) in 125 per cent NPK+ lime treatment in okra crop.
