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.

    ASSESSMENT OF SOIL QUALITY UNDER PREVALENT CROPPING SYSTEMS IN DIFFERENT AGRO-CLIMATIC ZONES OF HIMACHAL PRADESH.
    (CSKHPKV, Palampur, 15-07-19) Ravinder Kumar; Paliyal, S.S
    The present investigation entitled “Assessment of soil quality under prevalent cropping systems in different agro-climatic zones of Himachal Pradesh” was carried out with a view to ascertain the physical, chemical and biological properties of soils under prevalent cropping systems viz., maize- wheat, rice- wheat and vegetable based in different agro climatic zones of Himachal Pradesh. On the basis of detailed survey and random sampling, representative 180 soil samples from two depths i.e. 0-0.15 m and 0.15-0.30 m were collected. Soil samples were analyzed for their physical, chemical and biological properties and key indicators were identified using multivariate statistical analysis for computing the soil quality index. Wide variations in the soil health indicators were observed among different sites. The soil texture under various sites selected in the present study varied from sandy loam to sandy clay loam, however sandy loam was observed as the most dominant texture both under cereal and vegetable based cropping systems in all the four zones of the state. Soil reaction across various sites under present study was slightly acidic to neutral in Zone I-III but neutral to slightly alkaline in zone IV. Higher salt accumulation (EC) was observed under vegetable based cropping systems as compared to those of cereal based. Organic carbon was medium to high and available N, P and K contents were in low to medium category in all the four zones. Organic carbon and available and total N P and K contents were higher under the vegetable based cropping systems than cereal based. DTPA Fe, Mn, Zn and Cu were observed sufficient, whereas total Fe, Mn, Zn and Cu were recorded higher in cereal and vegetable based cropping system in all the zones. Microbial biomass carbon, microbial biomass nitrogen, potentially mineralizable nitrogen and soil respiration were higher at low hill subtropical zone in all cropping systems as compared to those in Zone-II, III and IV. The mean soil quality index (SQI) values for rice- wheat, maize- wheat and vegetable based cropping systems were 0.74, 0.74 and 0.81; 0.85, 0.77 and 0.81; 0.92, 0.68 and 0.73; 0.72, 0.71 and 0.78 in zone-1, II, III and IV, respectively. Overall higher soil quality index was observed under vegetable based cropping system as compared to the cereal based cropping systems.

    Integrated nitrogen management in maize-potato system in an acid Alfisol
    (CSKHPKV, Palampur, 07-01-19) Butail, Nagender Pal; Dixit, S. P.
    The present investigation was carried out at the experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur in randomized block design consisting of ten treatments combinations viz. control, 100 per cent mineral N, farmers’ practice, 100% mineral N +FYM (recommended), 25 and 50 per cent substitution of N through FYM, vermicompost and poultry manure, respectively. The experiment was conducted in maize-potato system for two years i.e. from kharif, 2015 to rabi, 2016-17. The soil of the experimental field was silty clay loam in texture, acidic in reaction (pH 5.31), medium in organic carbon (6.58 g kg-1) with 234, 21.4 and 185 kg ha-1 of available N, P and K, respectively. The micronutrient cations viz. Fe, Mn, Zn and Cu in the soil were 21.8, 19.1, 0.93 and 0.48 mg kg-1, respectively. Surface (0-0.15 m) soil samples taken at the harvest of each crop were analysed for water holding capacity, pH, organic carbon (OC), cation exchange capacity (CEC), available N, P, K and micronutrient cations viz. Fe, Mn, Zn and Cu. Microbiological properties i.e. microbial biomass carbon, microbial biomass nitrogen and soil respiration were also determined at harvest of potato, rabi 2015-16 and 2016-17. While different fractions of N were determined at the end of experimentation i.e. at the harvest of second crop of potato, rabi 2016-17. Plant samples of both the crops at the harvest of each crop, were analyzed for total N, P, K and micronutrient cations content and their respective uptake by both the crops were worked out. The present study revealed that integrated use of chemical fertilizer and different organic manures improved the soil physical, chemical as well as biological properties with highest value in the treatment where 100 % N was applied through chemical fertilizes +FYM at recommended rates. Highest yield of both the crops was recorded in same treatment and was significantly superior to the rest of the treatments followed by treatment where 50% N was substituted with poultry manure. Application of 50 per cent N through chemical fertilizers + 50 per cent N through poultry manure improved the nitrogen use efficiency as compared to the rest of the treatments i.e. 56.2 % at the end of experimentation. The contribution of different organic as well as inorganic forms of nitrogen viz., hydrolysable ammonical-N, amino acid-N, serine+threonine-N, hexosamine-N, unidentified-N, non hydrolysable-N, ammonical-N and nitrate-N, towards the total-N was 20, 23, 8, 7, 17, 15, 7 and 3 %, respectively. Different fractions of nitrogen were also found to be positively and significantly correlated with one another except non hydrolysable-N. Application of 50 per cent N through chemical fertilizers + 50 per cent N through poultry manure to both the crops recorded highest net returns as well as highest benefit cost ratio. It is concluded that the application of 100 per cent N through chemical fertilizers + FYM at recommended rates proved best treatment in terms of productivity, nutrients uptake and soil properties while 50 per cent N substitution through poultry manure proved to be the best treatment in terms of profitability and nitrogen use efficiency.
