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.

    Response of organic sources of nutrients in blackgram
    (palampur, 2022-08-24) Sachin; Singh, Janardan
    A field experiment was conducted at Model Organic Farm, Department of Organic Agriculture and Natural Farming, CSK Himachal Pradesh Krishi Vishvavidyalaya during the Kharif season of 2021, to evaluate the effect of organic sources of nutrient on growth and yield of blackgram. The experiment was laid out in randomized block design comprising of eight treatments [T1 − Bijamrita + Jiwamrita (5%, 10%, 10%, and 10%, respectively at time of sowing, 21, 42 & 63 DAS) + Mulching (10 t/ha), T2 – Bijamrita + Ghanajiwamrita (250 kg/ha) + Mulching (10 t/ha), T3 − Bijamrita + Jiwamrita (5%, 10%, 10%, and 10%, respectively at time of sowing, 21, 42 & 63 DAS) + Ghanajiwamrita (250 kg/ha) + Mulching (10 t/ha), T4 − Farm yard manure (10 t/ha), T5 − Farm yard manure (10 t/ha) + Ghanajiwamrita (250 kg/ha), T6 − Biofertilizers (Rhizobium + PSB) + Farm yard manure (10 t/ha) + Vermiwash at 15, 30 & 45 DAS (1:10), T7 − Biofertilizers (Rhizobium + PSB) + Vermicompost (7.5 t/ha) + Vermiwash at 15, 30 & 45 DAS (1:10), T8 − Absolute control]. Experimental site was silty clay loam in texture and acidic in reaction. Available nitrogen, phosphorus and potassium content were medium. The highest values of plant height, dry matter accumulation, unit area efficiency, absolute growth rate, yield attributes, seed yield, gross and net returns were recorded in T7 (Biofertilizers + Vermicompost + Vermiwash) whereas the highest benefit cost ratio was recorded in T6 (Biofertilizers + Farm yard manure + Vermiwash). The lowest values of the above said parameters were noted in T8 (absolute control) except net returns and benefit cost ratio which were the lowest in T1 (Bijamrita + Jiwamrita + Mulching). T7 (biofertilizers + vermicompost + vermiwash) proved to be the best treatment while T6 (Biofertilizers + FYM + Vermiwash) and T5 (FYM + Ghanajiwamrita) proved to be the second and third best treatment in enhancing productivity and profitability of blackgram, respectively.

    STANDARDIZATION OF THE DOSES AND TIME OF APPLICATION OF ‘JEEVAMRIT’’ IN WHEAT UNDER NATURAL FARMING SYSTEM
    (CSKHPKV, Palampur, 2019-05-27) Kaur, Puneet; Saini, J.P.
    A field experiment was conducted during Rabi 2017-18 at Holta organic farm of Department of Organic Agriculture, CSK HPKV, Palampur to standardize the doses and time of application of „Jeevamrit‟ in wheat under natural farming system. The experiment consisted of 10 treatments comprising of application of jeevamrit @ 5 per cent at 2, 3 & 4 weeks interval (T1, T2 & T3), jeevamrit @ 10 per cent at 2, 3 & 4 weeks interval (T4, T5 & T6), jeevamrit @ 20 per cent at 2, 3 & 4 weeks interval (T7, T8 & T9) and vermicompost @ 10 t/ha + 3 sprays of vermiwash @ 750 l/ha (T10). The basal application of Ghanjeevamrit @ 250 kg/ha + sieved FYM @ 250 kg/ha was done in all the plots except T10, at the time of sowing. Significantly higher grain yield (3117 kg/ha) was recorded with application of jeevamrit @ 20 per cent at 2 weeks interval (T3), which was at par with T2 (2967 kg/ha), T6 (2958 kg/ha), T10 (2891 kg/ha) & T5 (2861 kg/ha). However, significantly higher net return was recorded in T2 (Rs 54906/ha), which was at par with T5 (Rs 53875/ha), T3 (Rs 53251/ha), T6 (Rs 52225/ha), T1 (Rs 47785/ha), T9 (Rs 47843/ha) & T8 (Rs 47223/ha), however comparatively higher net return per rupee invested was recorded in T5 (1.69), which was also at par with T2 (1.61), T7 (1.57), T8 (1.57), T4 (1.54), T1 (1.54) & T9 (1.45), respectively. Microbial studies revealed that significantly higher colony forming units (cfu) of bacteria (32.69 × 106), fungi (24.86 × 103) and actinomycetes (6.02 × 102) per gram of soil were recorded in T3, which was at par with T2 (30.68 × 106, 23.18 × 103, 5.56 × 102) & T6 (29.34 × 106, 22.33 × 103, 5.55 × 102) cfu/g soil. Whereas, higher soil organic carbon (0.80%) was recorded in check (T10), which was at par with T3 (0.79%), T2 (0.77%) & T6 (0.76%) and higher available NPK (220.8, 36.6 and 200.6 kg/ha, respectively) were recorded in check (T10) after the harvest of crop.

    Eco-friendly Management of Rice Weevil, Sitophilus oryzae (L.) on Stored Wheat
    (CSKHPKV, Palampur, 2018-09-29) Mehta, Vasu; Surjeet Kumar
    The studies were conducted in the laboratory of the Department of Entomology, CSKHPKV, Palampur, India during 2017-18 with the objectives to determine relative susceptibility/resistance of seven cultivars of wheat to rice weevil, Sitophilus oryzae (L.) and to evaluate different plant powders as grain protectants against the weevil. The main aim of the study was to find eco-friendly alternatives to the chemical fumigants used against the weevil in stored wheat. On the basis of biological parameters of rice weevil and extent of its damage none of the varieties was found to be free from weevil infestation and damage. However, HPW-249, HPW-349 and HPW-360 were observed to be less susceptible, HPW-155, HS-490 and VL-892 were categorized as moderately susceptible and HPW-236 was highly susceptible. Among seven varieties, HPW-360 had the lowest oviposition (17.33%) and adult emergence (23.33 adults), the longest developmental period (43.67 days), the lowest monthly increase in population (87.0 days), the lowest value of susceptibility index (7.19) and orientation of the weevil (4.33 adults) and least grain damage (26.22%) and weight loss (6.59) while HPW-236 had the highest oviposition (64.0%) and adult emergence (87.33 adults), maximum orientation (27.33 adults) and monthly increase in population (243.44), highest value of susceptibility index (13.55), grain damage (58.67%) and weight loss (18.92%). Different plant powders, evaluated for their effects on the adult mortality and population build-up of S. oryzae and on the extent of damage by the weevil, proved highly effective in comparison to untreated control. The leaf powder of Ageratum conyzoides proved to be the best treatment against the weevil which resulted into maximum mean cumulative mortality (96.67%), the lowest monthly average of population increase (18.33) and the least grain damage (12.61%) and weight loss (1.75%) in six months of storage. The next best treatment was the drupe powder of Melia azedarach followed by Vitex negundo and Ocimum sanctum. These treatments did not cause significant reduction in seed germination. A. conyzoides, M. azedarach and O. sanctum were found effective even after three months of their preparation. The leaf powder of Murraya koenigii resulted into the lowest mean cumulative adult mortality (14.23%), the highest monthly increase in population (132.78), the highest grain damage (47.50%) and weight loss (11.07%) and the lowest germination (21.67%) after five months of treatment. Thus, this treatment proved to be the least effective against the weevil.
