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.

    Productivity and soil quality assessment in maize-wheat system under zero budget natural farming
    (palampur, 2022-10-13) Thakur, Praveen; Paliyal, Sukhdev S.
    The present study on “Productivity and soil quality assessment in maize-wheat system under zero budget natural farming” was carried out during 2018-19 and 2019-20 at the experimental farm of CSKHPKV-Hill Agricultural Research and Extension Centre, Dhaulakuan, Sirmour (H.P.), India. The efficient utilization of available resources at farm and the restriction of their use in zero budget natural farming (ZBNF), warrant the need to study the soil quality and crop productivity under ZBNF system. Therefore, the present study was undertaken to assess the soil quality in maize-wheat system using ZBNF components along with farm yard manure (FYM). The field experiment was laid out in a randomized complete block design (RCBD) consisting of three factors (jeevamrit concentration, interval of its application and FYM) along with control. There were two levels of jeevamrit concentration [5% (J1) and 10% (J2)], two levels of interval of its application [15 days (I1) and 30 days (I2)] and three levels of FYM doses [0 t ha-1 (F1), 5 t ha-1 (F2) and 10 t ha-1 (F3)]. The soil samples at 0-0.15 m depth from each plot were collected before sowing as well as after harvest of the both crops and were analyzed for soil chemical properties such as pH, electric conductivity, organic carbon, cation exchange capacity, macronutrient content (N, P and K), secondary nutrient content (Ca, Mg and S) and micronutrient content (Fe, Mn, Zn, Cu, B and Mo), physical properties (bulk density, mean weight diameter, saturated hydraulic conductivity and plant available water), biological properties (microbial biomass carbon, dehydrogenase activity and microbial count). The results revealed that growth and yield attributes of both maize + blackgram and wheat + chickpea were increased with application of higher concentration of jeevamrit (J2) at 15 days interval along with higher dose of FYM (F3). Maize grain equivalent yield with jeevamrit (J2) at 15 days interval+10 t FYM ha-1 treatment increased upto 4.71% during 2018 and 8.42% during 2019 whereas wheat grain-equivalent yield decreased upto 4.17% during 2018-19 and 0.47 % during 2019-20, over control (RDF). Soil physical, chemical and biological parameters were improved significantly under zero budget natural farming and these properties improved further when FYM was applied along with ZBNF component over RDF. Available nutrient status in soil under RDF treated plots showed slight decrease from initial value, however the plots treated with higher concentration of zero budget natural farming components along with higher dose of FYM showed significant increase from rest of the treatments. The SQI under maize and wheat crop ranged from 2.60 to 3.67 and 2.56 to 3.71, respectively and the highest was observed under T6 (J2I1F3). The maximum nutrient uptake in both crops and its concentration in their grain was found with higher concentration of jeevamrit at 15 days interval along with 10 t FYM ha-1 , whereas the lowest were recorded with lower concentration of jeevamrit at 30 days interval without FYM.
