Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    EFFECT OF PLANT GROWTH PROMOTING RHIZOBACTERIA AND CHEMICAL FERTILIZERS ON CROP PRODUCTIVITY AND SOIL PROPERTIES IN WHEAT- MAIZE CROPPING SYSTEM UNDER RAINFED CONDITIONS
    (UHF,NAUNI, 2016) SOOD, GAURAV; KAUSHAL, RAJESH
    ABSTRACT Wheat (Triticum aestivum L.) and Maize (Zea mays L.) are members of Poaceae family, ranked among the top three cereal crops of the world. Cereals constitute the staple food of Indians and about 61% of the protein requirement is met through these crops. Wheat and Maize requires large amount of nitrogen and phosphorus in comparison to other essential nutrient elements. The deterioration of soil health coupled with decreasing nutrient use efficiency is a matter of great concern which compelled the scientists to explore renewable low cost non bulky inputs to bridge the gap of crop production which can improve the crop productivity and also sustain soil health. So, the present investigations were carried out to study the effect of plant growth promoting rhizobacteria and chemical fertilizers on crop productivity and soil properties in wheat- maize cropping system under rain fed conditions. A total of 127 isolates were isolated from all the four agro-climatic zones of Himachal Pradesh, out of which 67 bacterial isolates (36 from rhizosphere and 31 from roots) were morphologically and physiologically characterized and tested for multifarious PGP traits viz. phosphate solubilization (390.20- 408.68 µg/ml), HCN production, Growth on nitrogen free medium (3-6 mm colony diameter), auxin production (27.23- 32.77 µg/ml) and siderophore production (17.18- 29.38 % siderophore unit) as well as antagonism against Alternaria triticina, Claviceps purpurea and Fusarium graminearum. Three isolates (B2, SIR1 and BIS2) exhibited maximum multifarious PGP traits. On the basis of morphological, biochemical and molecular (16S rRNA gene sequencing) characteristics possessed by the selected isolates, they were identified Serratia sp. (B2) and Bacillus subtilis (SIR1). Three isolates (B2, SIR1 and BIS2) for wheat and (B1N1, DHK and J2) for maize possesses maximum PGP attributes were screened at different doses of N & P fertilizer (80, 60 and 40% of recommended doses of NP) levels under net house conditions and finally two isolates (B2 and SIR1) for wheat and (B1N1 and DHK) for maize along with optimum dose i.e. 80% of NP were selected for field experimentation. The application of selected isolates (B2 and SIR1) for wheat and (B1N1 and DHK) for maize at 80% recommended dose of N and P fertilizers level not only registered significant increase in yields for two consecutive years over uninoculated control (100% recommended doses of NPK fertilizers) besides a saving of 20% N and 20% P fertilizers. Similarly, the application of indigenous plant growth promoting isolates (B2 and SIR1) in wheat and (B1N1 and DHK) in maize can induce drought tolerance by increasing the antioxidant enzymes (SOD, CAT and POD) activities in addition to their ability to act as PGPR. The application of indigenous PGPR isolate (B2) reduced the disease incidence against Alternaria leaf blight by 20.00% as compared to chemical control. The B2 isolate for wheat and B1N1 for maize can be used as biofertilizers, biostimulants and bioprotectant and the conjoint application of B2 and B1N1 isolate for wheat and maize at 80 per cent can be recommended for multi locational trials in different agro-climatic zones of H.P.
