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.

    Design, development and testing of modular metering mechanism for multi crop planter
    (CCSHAU, 2012) Chaudhary, Pooja; Bansal, N. K.
    India will have to produce 300 million tonnes of food grains to feed her 1.19 billion populations. Sowing technique is most important operation performed in agriculture because production mainly depends upon field emergence and initial crop establishment. Presently, different sowing machines are used for various crops like Bt. cotton planter, zero till machine for wheat and DSR machine for direct seeding of rice and it is not possible for a farmer to have different machines for sowing different crops. Therefore, tractor drawn multi-crop planter was designed, developed and evaluated having provision of sowing all major cereal crops, pulses and oilseeds at desired row to row as well as seed to seed spacing especially for paddy by direct seeding technique and Bt. Cotton. The developed ground wheel was of 380 mm diameter having provision of chain sprocket arrangement of power transmission through a designed gear box with varying speed ratio of 1.6 to 4.5 times reduction from ground wheel to seed metering plate. The diameter of seed metering plate was 140 mm with varying number of cells and cell size to suit recommended spacing of major crops. The speed reduction of ground wheel to fertilizer metering shaft is 2.3:1. The fertilizer hopper has inclinations for accomplishing easy emptying and better utilization of fertilizer from hopper to fertilizer box having vertical roller discs with eight cells in each disc. The two depth control levers and separate seed hopper and seed metering mechanism/attachment with six vertical roller discs having 8 cells each was provided for small seeded crops. The performance evaluation of developed prototype was carried out under field condition for Bt. cotton and direct seeding of rice. The effective field capacity of machine for both crops was 0.50 ha h-1 and 0.45ha h-1 respectively at an average forward speed of 3 km h-1 with time lost in turning of prototype 35 sec/turn and the corresponding field efficiencies were 61 per cent and 83 per cent respectively. The field emergence (No. of plants /10m furrow length) observed in Bt. cotton planter was 12-21 plants (7days after planting), 18-30 plants (15 days after planting) and 20-28 plants (21days after planting) in Bt. cotton crop whereas field emergence of 125-140, 135-155 and 140-150 plants 7DAS, 15DAS and 21DAS was recorded in DSR crop. The distribution of plants in row and crop response at field indicated that mean plant spacing observed was 48 cm and 10 cm with a quality of feeding index 77 per cent and 78 per cent respectively for Bt. cotton and DSR crop. The missing index and multiplying index recorded in Bt. cotton were 15% and 8% respectively, while, 16% and 6 % in DSR crop. The precision in spacing observed was 6.3 percent and 7.08 per cent in Bt. cotton and DSR respectively. The average plant height recorded 21 DAS in Bt. cotton and DSR was 15 cm and 13 cm respectively. The cost of operation calculated for Bt. cotton and DSR crop was Rs ha-1 700 and Rs ha-1 777 respectively.

    Performance evaluation of root crop digger
    (CCSHAU, 2012) Narender; Vijaya Rani
    India is world s largest producer of vegetables after China and contributes about 14% of world vegetable production in year 2010-2011. In vegetables, potato, onion and carrot are the important root crops. In Haryana, potato (Solanum tuberosum L.) is grown in an area of 0.03 million hectares and production is 0.59 million tonnes and onion (Allium Cepa L.) in an area of 0.022 million hectares with a production of 0.45 million tonnes and carrot in an area of 0.02 million hectares giving a production of 0.315 million tonnes. The harvesting of root crop is presently done manually in India which is very tedious and time consuming. Moreover, sometime labour problem arises during harvesting operation. Though there are diggers available for different crops independently, they are not much accepted by the farmers. Therefore, it was proposed to evaluate the root crop digger which was designed to dig different crops namely potato, onion, carrot, turmeric, garlic etc. Five parameters i.e. exposed, cut, undug, bruised crop and digging efficiency of digger were studied at three different forward speed and blade angle to evaluate the performance of root crop digger for potato, carrot and onion crop. The optimized value for performance of the root crop digger was at speed 2.3 km h-1 and blade angle 230 for potato, speed 2.2 km h-1 and the blade angle 230 for carrot and speed 3.2 km h-1 and the blade angle 170 for onion crop. The field capacity of root crop digger was 0.21, 0.18 and 0.25 ha h-1 in potato, carrot and onion crop, respectively. The field efficiency of the root crop digger was 65 %, 65 % and 80 % for potato, carrot and onion, respectively. The saving in cost of mechanical digging was found to be 8384 Rs ha-1, 7359 Rs ha-1 and 5615 Rs ha-1 for potato, carrot and onion, respectively in comparison to conventional method. The break-even point for root crop digger was 35.14 hour per year. The payback period of root crop digger was 0.24 year.
