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.

    ECOFRIENDLY MANAGEMENT OF BELL PEPPER DISEASES UNDER PROTECTED CULTIVATION
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2012) ASHLESHA; Paul, Y.S.
    Present investigations on diseases of bell pepper under protected cultivation were undertaken to study the progress of diseases, environmental factors affecting diseases, evaluation of various organic inputs against pathogens of bell pepper and to work out suitable ecofriendly management strategies. Survey of bell pepper growing polyhouses was conducted in six districts of Himachal Pradesh namely Kangra, Hamirpur, Bilaspur, Una, Kullu and Mandi. Maximum incidence of bacterial wilt was observed in Zmanabad (83.3%) and Sai (70.5%) areas of Kangra, whereas severity of powdery mildew was maximum in Katrain (34.6%) area of Kullu. There was a positive significant correlation between disease severity of powdery mildew and bacterial wilt and maximum daily temperature. Organic inputs viz., cow urine and panchgavya provided 100% inhibition of all the fungal pathogens followed by vermiwash (90.6-100.0%) at 10% concentration in vitro. Biodynamic compost tea and biosol caused 95.6 and 92.3% inhibition of bacterium (Ralstonia solanacearum) at 4% concentration. Seedling dip in Orguard (a new formulation) for 1 hour increased the survivability of seedlings upto 27 days in comparison to check. Organic inputs showed the presence of total 92 isolates, but only 12 isolates which were the species of Bacillus, Pseudomonas, Serratia and Actinomycetes exhibited strong antifungal properties against capsicum pathogens. Based on in vitro evaluation, three isolates of Bacillus (AB8B2, AP13B4 and AM15B5), one each of Serratia (AP18S) and Actinomycetes (AV10A2) showed strong antifungal activity against pathogens of capsicum. All the species of Bacillus were found most inhibitory to Sclerotinia sclerotiorum (99.7%) followed by Fusarium oxysporum and Fusarium solani (92.0–97.0%). The antagonistic isolates also exhibited plant growth promoting traits. Among these, six isolates were selected as efficient phosphate solubilizers and maximum solubilization was shown by AB8B2 (365.2 μg P/ml). All the isolates showed IAA production and nitrogenase enzyme activity and six isolates produced siderophores. Cow urine distillates of five botanicals viz, Ranunculus muricatus, Melia azedarach, Vitex negundo, Eupatorium sp and Murraya koenigii were evaluated against test pathogens. Out of these, distillates of V. negundo and M. koenigii provided 100% inhibition of all the test pathogens at 10% concentration. Organic inputs found effective under in vitro conditions were tested in farmers‟ polyhouses at three locations in Kangra. Drench of Orguard before transplanting and at 15 days interval provided more than 85.0% control of bacterial wilt. Spray of milk along with sulphur and asafoetida resulted in more than 80.0% control of powdery mildew of capsicum under protected cultivation.
