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 PERFORMANCE OF IMPROVED GRASSES ON DEGRADED GRASSLAND UNDER MID HILL CONDITIONS OF H.P.
    (CSKHPKV, Palampur, 2018-08) Shalley; Rameshwar Kumar
    A field experiment was conducted during July 2016 to October 2017 at Agroforestry Farm of Department of Horticulture and Agroforestry, CSK HPKV, Palampur to study the performance of improved grasses on degraded grassland under mid hill conditions of H.P. The experiment consisted of 7 treatments comprising of Setaria, Brachiaria, White clover and their 3 combinations viz; Setaria+White clover, Brachiaria+White clover, Setaria+ Brachiaria+White clover and control. The experiment was laid out in Randomized Block Design with three replications. The soil of the experimental site was sandy clay loam in texture and acidic in reaction. It was rated as medium in organic carbon, available nitrogen, available phosphorus and available potassium. Observations were recorded on various growth and development, yield, quality, soil and economy parameters. Setaria+White clover treatment proved to be the best combination as it recorded significantly highest green (27.11 t ha-1) and dry fodder yield (4.98 t ha-1). Productive potential of the degraded grassland increased 3.2, 2.7 and 2.5 times by the introduction of improved grasses Setaria+ White clover, Setaria and Setaria+Brachiaria+White clover respectively. Fodder was analyzed for various quality parameters at the time of different cuts of forages. Most of the parameters were higher in pure Setaria as compared to other grasses like dry matter content (19.24%), ADF (47.68%), oxalate (3.18%) and lignin (6.56%) while NDF (67.20%) and ash (9.80 %) were higher in pure Brachiaria grass. White clover when grown pure had highest crude protein content (20%). Setaria grass when mixed with White clover had higher crude protein yield 6.31 q ha-1 than all other combinations of grasses. Higher net return of Rs. 11,175.8 ha-1 was obtained in Setaria and White clover. B:C ratio was higher in White clover (0.42) than all other treatments of forage species. Minimum B:C ratio was obtained in Setaria+Brachiaria+White clover because of high cost of rootslips.

    EFFECT OF CONTINUOUS APPLICATION OF FERTILIZERS AND AMENDMENTS ON PRODUCTIVITY, QUALITY OF WHEAT (Triticum aestivum L.) AND SOIL HEALTH IN AN ACID ALFISOL
    (CSKHPKV, Palampur, 2018-07) Chauhan, Neha; Sankhyan, S. K.
    The present investigation was carried out to study the effect of continuous cropping and fertilization on productivity, quality of wheat (Triticum aestivum L.) and soil health in an acid Alfisol under maize - wheat cropping system in an ongoing long-term fertilizer experiment. This experiment was initiated during 1972 at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur in randomized block design with eleven treatments which were replicated three times. The soil of the experimental area was silt loam and classified taxonomically as “Typic Hapludalf”. Soil samples were collected from surface (0 - 0.15 m) and subsurface (0.15 - 0.30 m) layers after the harvest of wheat (rabi, 2016-17). Samples were analyzed for various physical, chemical and biological soil health parameters using standard methods of analysis. Physical soil health parameters included bulk density, particle density, porosity and water holding capacity whereas, among chemical soil health parameters pH, OC, major nutrients and micronutrient cations were determined. Biological soil health parameters i.e. microbial biomass carbon and microbial biomass nitrogen were estimated. Besides, crop quality parameters such as crude protein, gluten, moisture, ash, fat, fibre and carbohydrate content were also determined. The highest productivity and nutrient uptake in wheat was recorded in the treatment comprising 100 per cent NPK + FYM and was statistically comparable with 100 per cent NPK + lime. Balanced fertilization along with manures improved the soil physical condition, maintained soil nutrient status and enhanced biological activity of soil thus sustained productivity and improved soil health. Application of FYM along with recommended doses of fertilizers improved all the crop quality parameters as compared to control. Continuous cropping without fertilization for the last forty-five years led to decline in crop quality parameters. In general, all the soil health parameters were positively correlated with wheat yield and quality traits except bulk density, particle density and grain moisture which were negatively correlated.

    EFFECT OF ORGANIC AMENDMENTS ON SOIL HYDRO-PHYSICAL PROPERTIES AND WATER USE EFFICIENCY OF POTATO IN AN ACID ALFISOL
    (CSKHPKV, Palampur, 2018-07) SUWALKA, MAHENDRA; Sandal, Sanjeev K.
    The present study was conducted in the on-going long term experiment on potato (2006 onward) at the Experimental Farm of Department of Organic Agriculture, College of Agriculture, CSKHPKV, Palampur, during the year 2016-17 with the objectives of evaluating the long term effect of FYM, himcompost and vermicompost addition on soil hydro-physical properties and soil water dynamics and on plant growth, crop productivity and water use efficiency of potato. The treatments comprised of T1 - FYM @ 20 t ha-1, T2 - Vermicompost @ 15 t ha-1, T3 - Himcompost @ 10 t ha-1, T4 - FYM @ 10 t ha-1 + Himcompost @ 5 t ha-1, T5 - Vermicompost @ 7.5 t ha-1 + Himcompost @ 5 t ha-1, T6 - FYM @ 10 t ha-1 + Vermicompost @ 7.5 t ha-1 and T7 - Control (FYM @ 5 t ha-1). Seven treatments were replicated in a randomized block designs. The potato cv. Kufri Jyoti was sown on December 17, 2016. The results indicated that T6 treatment had higher soil water content. soil water stock, profile water recharge as compared to other treatments. Treatment T3 had higher plant height, number of leaves per plant at 60 and 90 DAS, plant root parameter (root volume and weight) at harvest and relative leaf water content (RLWC) in comparison to other treatments. Marketable tuber yield was higher in T5 but haulm yield was higher in T6 as compared to other treatments. The crop water use was higher under T5 and T2 at 0-0.30 and 0-0.60 m soil depths, respectively, over other treatments. However, highest water use efficiency (WUE) was recorded in T5 as compared to other treatments at 0-0.30 and 0-0.60 m soil depths. Soil nutrient status determined at harvest of potato indicated that T2 had higher organic carbon content, available nitrogen and phosphorus whereas potassium was higher in T5 compared to other treatments. Total N and P uptake was higher in T5 and total K uptake was higher in T6 as compared to other treatments. The treatment T1 had lower mean weight diameter, bulk density and saturated hydraulic conductivity whereas porosity was higher in T1 at surface and subsurface soil depth as compared to other treatments. The water holding capacity was higher under T6 at 0-0.15 and 0.15-0.30 m soil depths in comparison to other treatments. The coefficient of correlation (r) between porosity and water holding capacity and mean weight diameter and saturated hydraulic conductivity was significantly positively correlated and between porosity and saturated hydraulic conductivity and porosity and mean weight diameter was significantly negatively correlated.
