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 WEATHER PARAMETERS ON THE PRODUCTION OF CEREAL CROPS IN SOLAN DISTRICT OF HIMACHAL PRADESH
    (2013) ELIBARIKI, RAHELI; AGGARWAL, R.K.
    ABSTRACT The present investigations entitled “Effect of Weather Parameters on the Production of Cereal Crops in Solan district of Himachal Pradesh” was conducted during 2012-2013 in the Department of Environmental Science, Dr. Y. S Parmar University of Horticulture and Forestry, Nauni, Solan. Weather data for the period (1984 - 2011) and the data of cereal crops for the period (1996-97 to 2010-11) were analyzed. To compute the trends of weather parameters for annual, seasonal, monthly and weekly data, measures of central tendency and variation (mean, standard of deviation, Skewness and Kurtosis), regression coefficient whereby different functions including quadratic, cubic, compound, growth, exponential and logistic functions were fitted and the best fit functions were selected on the basis of R2 value and Sen’s estimate analysis was used to find out the trends of weather parameters which stabilize the data in the form of median values. Effect of weather parameters on crops yields were carried out using regression analysis whereby each individual weather parameter was correlated with crop yields and also multi-linear regression (combinations of all the selected weather parameters) equations were obtained. The results of variability analysis revealed no significant trends for the selected weather parameters and also kurtosis and Skewness did not show any normality assumptions. In case of regression analysis cubic and quadratic functions were found to be the best fit for the selected weather parameters. In annual analysis the highest R2 value was 0.6 in case of maximum temperature, while for all other weather parameters the R2 value varied between 0.06 – 0.40. Sen’s estimate analysis indicated increasing trend of maximum temperature by 3.0oC, minimum temperature by 0.5oC and decreasing trend of rainfall, relative humidity and sunshine hour. Analysis of relationship of crops yields with time also did not show any significant trend in regression analysis, however, in Sen’s estimate all the selected crops showed increasing trend. Effect of individual weather parameters to crops yields found to be non- significant, however, in multiple-linear regressions analysis effect of weather parameters on crops yields found to be significant with R2 value of 0.70 for wheat, 0.60 for rice and 0.50 for maize, indicating thereby that crops yields are influenced by combinations of weather parameters not a single weather parameter.
