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 weeders in cotton
    (CCSHAU, 2014) Mor, Aman; Bansal, N.K.
    The performance of different types of weeder was evaluated so that the farmers can make a decision while purchasing the weeder of good quality. The present study was carried out to predict the performance of tractor operated and engine operated inter row rotary weeder and it was compared with traditionally used tractor drawn high clearance cultivator and manual hand hoe (Kasola). The crop and machine performance parameter were recorded at three stages of cotton crop i.e. pre-square, square and flowering. The soil resistance was recorded before, just after weeding (3rd stage) and at the time of harvest. The plant height, canopy of plant & weeding efficiency were recorded at three stages i.e. pre-square, square and flowering. Yield data (g/plant) was recorded under all the treatments taken in both varieties. The weeding efficiency with the use of tractor operated weeders was obtained up to the level of 74 to 76 per cent whereas it was 85.5 to 89.59 per cent with manual hand hoe. There was a significant difference in plant height at square and flowering stage whereas the canopy of plant was significant only at flowering stage. There was no significant effect on bolls per plant and lint yield per plant with the use of mechanical weeder. The field capacity of tractor operated inter row rotary weeder was in the range of 0.54 to 0.59 ha/h whereas it was 0.8 ha/h in tractor operated high clearance cultivator, 0.16 ha/h with engine operated power weeder and 0.05 ha/h with manual hand hoe. The per cent saving in cost of operation with mechanical weeder over manual hand hoe was in the range of 80 to 93. The B:C ratio of mechanical weeder selected for study was in the range of 1.57 to 4.4 and payback period was in the range of 0.44 to 1.7 years. Time saving over manual hand hoe in weeding operation with the use of tractor operated weeder was 90 to 93 per cent whereas in engine operated weeder it was 68.7 per cent over manual hand hoe. The per cent saving in labour requirement with the use of mechanical weeder was in the range of 96 to 99 per cent over manual hand hoe. The pulse rate after weeding operation in all the treatment were in the range of 104 to122 beats/min whereas the blood pressure was slightly higher with the use of engine operated power weeder (142/90) and manual hand hoe (135/88). Based on study the tractor operated inter row rotary weeder (Make, M2) is recommended.
