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.

    Performance evaluation of bed planter for intercropping in castor
    (CCSHAU, 2011) Ajit Singh; Vijaya Rani
    In India, the area and production of castor is 0.74 million hectares and 0.93 million tonnes, respectively. Castor (Ricinus communis L.) is most important oilseed crop of India due to the fact that its oil has diversified uses and has great value in foreign trade. The intercropping in castor is carried out on flat bed. Firstly, castor is sown manually or by pora method and the other pulse crops of short duration are inter-sowed by seed drill. The process of sowing castor which is done manually or by animals drawn sowing plough is very tedious and time consuming. Thus, there was a need to evaluate the feasibility of raised bed system for intercropping of pulse crop in castor over existing practice of intercropping. The different physical properties of the castor seed were determined for dry seed (5.9 %), seed soaked for 6 hours (25.8 %) and seed soaked and 12 hours (32.8 %). The average length, average width and average thickness were found to increase with increased moisture content. The values for spherecity and roundness were not close to 100 % and hence seed shape could be considered oval. The gravimetric properties of the castor seed as 1000 seed weight, single seed volume and bulk density increased as soaking hours increased from 0 to 12 hours. True density and porosity increased for first 6 hrs of soaking and then the values decreased when the hours of soaking further increased form 6 to 12 hours. The effective field capacity of planter was 0.50 ha h-1at average operating speed of 3.9 km h-1. The missing index, multiplying index and quality of feed index recorded for bed planter were 10.71 %, 1.19 % and 88.10%, respectively. Payback period of bed planter and seed drill were calculated were 1.51 and 0.58 year. Break-even points in hr per year were 44.75 and 25.85 in case of bed planter and seed drill. The plant stand obtained after 21days of sowing was higher for raised bed than flat bed by 24.33%, 23.33% and 24.33 % for castor intercropped with green gram, moth bean and cluster bean. Significant difference was obtained for plant height at 30, 45, 60 days and at primary spike for castor crop. The plant height was more for raised bed intercropping than flat bed intercropping for both castor and pulse crop. Number of capsules/spike, number of pods/plant, length of spike and length of pod were also higher for the raised bed intercropping than flat bed intercropping. Thousand grain and seed weight for pulse and castor obtained was higher for castor crop and for pulse crop on raised bed than flat bed. The yield (q ha-1) for pulse and castor obtained was 31.33 %, 29.77 % and 30.43 % higher for castor crop and 4.51 %, 5.2 % and 6.27 % for pulse crop, respectively on raised bed than flat bed.
