Chaudhary Charan Singh Haryana Agricultural University, Hisar
Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

For many cropping situation, especially in developing countries some models do not fit the responses of certain crops to fertilizer. Performance of quadratic, square root, inverse quadratic and modified quadratic response functions have been examined on major food crops grown in Haryana. Based on R2 criterion, inverse quadratic model gives better fit to Pearlmillet crop, where as quadratic function describes the yield-fertilizer relationship in Rice crop. It has been observed that a modified quadratic function is better suited when data shows initial sharp rise at lower levels of fertilizer application. Fertilizer yield data of wheat is often available of many varieties and/or for a numbers of years. Dummy variables have used for combining data for different varieties and over years and for testing structural stability of quadratic response function for three varieties; HD2329,WH542 and WH533 of wheat crop grown in Haryana. Models for individuals varieties have also been deduced from the pooled regression. A comparative study of quadratic, square root, inverse bilinear, and cobb-douglas response models used for the two nutrients experiment. The canonical form is also performed for quadratic and square root models. The characteristic roots of real symmetric matrix of estimates are measured for the coefficients of quadratic and interaction terms. Based on characteristic roots and R2, square root model give better fit for wheat crop.ThesisItem Open Access Evaluation of fertilizer yield response models(CCSHAU, 2005) Suman Kumar; Rajendra SinghJudicious use of fertilizer form one of the most important means of stepping up agricultural production.

The daily rainfall data for 79 years (1925-2003) for the period from June to September have been split into 3 phases viz., 1925-1953, 1954-1978 and 1979-2003. These phasewise data have been categorized into 5 states / categories accordingly as non-rainy day (D), light rainy day (W1), moderate rainy day (W2), heavy rainy day (W3) and very heavy rainy day (W4). The transitional probabilities were estimated for all states / categories of occurrence by using Markov chain of order one representing conditional dependence on preceding one day only. The transitional probabilities were estimated by maximum likelihood principle for all the three phases. By using the knowledge of the Shannon’s entropy, the uncertainty (or disorderness) of the transitional system of the south-west monsoon daily rainfall characteristics (such as non-rainy day, light rains, moderate rains, heavy rains and very-heavy rains) have been studied. The favourable or unfavourable condition of different states during the south-west monsoon period at Hisar have also been tested by the redundancy test. It has been found that in the month of June and September the redundancy is more as compared to July and August. For the whole season i.e. June to September, the redundancy test confirms the favourableness of Markov chain of order one at Hisar.ThesisItem Open Access Statistical evaluation of spatio-temporal development in Haryana(CCSHAU, 2005) Sangwan, Sangeeta; Manocha, VeenaThe level of development of various districts of Haryana state were estimated separately for agricultural, industrial, infrastructure & services and overall socio-economic sectors with the help of composite index of development based on optimum combination of forty seven development indicators combined in an optimum manner. The study utilized data for different districts over various periods ending triennium 1971-72 (Period I), 1981-82 (Period II), 1991-92 (Period III), and 2001-02 (Period IV). Out of forty seven development indicators, twenty three indicators were directly concerned with agricultural development, four indicators depicted the progress of development in the industrial sector and the rest of twenty indicators presented the level of development in infrastructure & service sector. All the forty seven indicators taken together represent the overall socio-economic development for this study. The variation in the level of development in industrial sector was observed to be of higher order as compared to the variation in agricultural and infrastructural services sector. Positive significant association was observed between the levels of development in agricultural and overall socio- economic development in all the periods of study except the first period. The non significant association was found between agriculture and industry which is not a healthy situation. No significant changes in the level of development were observed between different periods in agricultural, industrial and overall socio-economic sectors. However, a significant change was found in the level of development of infrastructural service sector between the first and fourth, second and fourth and third and fourth periods. The different districts have been classified as highly developed, developed, developing, backward and very backward on the basis of quintiles classification from an assumed Beta distribution of the mean of the indices for all the sectors. For bringing about uniform regional development in the state, model districts for the backward / very backward districts have been identified and the potential targets for various indicators have been estimated. The study revealed that the backward / very backward districts required improvements of various dimensions in almost all the indicators for enhancing their level of development in different sectors.
