Description |
Mechanization requires appropriate machinery for ensuring timely field operations, effective application of crop production inputs and reducing drudgery. Agricultural productivity is linked with the availability of farm power. Bullocks meet power requirements of marginal and small farms (less than 2 ha) with associated limitation. Tractors meet requirement of large farms (above 6 ha). Power tillers are visualized as appropriate source of farm power of medium farms (2-6 ha), where India’s agricultural holdings pattern shows that 26% of area under cultivation is under medium holdings of 2 to 6 ha. Rice (Oryza Sativa) is a crop of paramount importance. It is one of the three most important food crops in the world which forms the staple diet of 2.7 billion people. The need of the hour is to reduce cost of cultivation and the production has to be increased. Direct sowing of rice can eliminates seedbed preparation in a nursery, pulling seedlings, hauling and transplanting operations. Total area under rice cultivation in Andhra Pradesh is 42 million hectares. Maize (Zea mays L.) is also one of the most important cereals of the world with its world and provides more human food than any other cereals. India stands in the fifth place where as with respect to production it ranks eleventh. Among the major producing states Andhra Pradesh stand in first with contribution of 17% to total Indian maize production (Maize out look report by KARVY). Maize cultivated area in Andhra Pradesh in Kharif is 5.62 lakh hectares, in Rabi 2.48 lakh hectares during 2008-09. In order to mechanize crop sowing operation, a suitable drill attachment for power tiller is vital as it places the seed and fertilizer in the zone of adequate moisture and at desired depth. The commercial available animal drawn seed cum fertilizer drill was modified for sowing maize and paddy crops with power tiller. The over all length of the Seed-cum-Fertilizer Drill was 1500 mm, width 700 mm and the height was 900 mm. The diameter of the drive wheel was 550 mm. The drive to the seed metering and the fertilizer metering can be obtained by shifting a dog clutch attached to one of the ground wheel. The drive was provided to the metering mechanism was through a sprocket and chain mechanism. The cell feed type metering mechanism was used for sowing the seeds. The fertilizer will be metered with an agitator over an orifice. The effective field capacities of the power tiller drawn seed cum fertilizer drill for maize and paddy crops were found to be 0.12 ha/h and 0.08 ha/h respectively. Theoretical field capacities of the power tiller drawn seed cum fertilizer drill were 0.18 and 0.12 ha/h. The field efficiency of the machine for maize and paddy crops was found to be 67%. Grain yield of maize and paddy crop were 3626 kg/acre and 1.85 kg/acre. An additional income of Rs. 5248.40/- and Rs. 2206.80/- was observed over bullock drawn and tractor drawn implements in maize crop. In paddy an additional income of Rs. 2524.16/- and 873.86/- was observed over bullock drawn and tractor drawn implements with power tiller drawn seed cum fertilizer drill. Key words: power tiller, maize, paddy, frame, ground wheel, cell feed type metering mechanism, effective field capacity, theoretical field capacity, efficiency, grain yield, production cost and net income. |
