Abstract
Sowing is a very important operation during sowing season, there is an acute shortage of labour, which causes delay in sowing of crop which ultimately results in a reduction in yield similarly weeding operation is one of the important intercultural tillage operation which control unwanted plants between the rows that consume more fertilizers and reduces the crop yield. There was a need of versatile machine which overcome the economic constraints of the farmers and could perform for both sowing and Intercultural operations. Therefore the project was undertaken on performance evaluation of small tractor operated seed ferti drill cum inter row cultivator in the Department of farm power and machinery, Dr. Panjabrao Deshmukh Krushi Vidyapeeth, Akola.
Around 90 per cent of farmers fall in the category of small, marginal and semi-medium land holding in India and the purchase of higher horse power tractor and implements is beyond the economic capacity an average of the Indian farmers. The higher horse power tractor operated machineries are not suitable for small and scattered land holdings since it gives low field efficiency in small fields. Presently the farmers are using bullock drawn or tractor drawn seed drills for sowing and similarly both the powers are being used for interculturing operation.
The seed ferti drill cum inter row cultivator was calibrated in the laboratory for sorghum, chickpea and maize seed and the desired seed rate was obtained 13.84, 79.76 and 23.28 kg/ha, respectively. The average row to row spacing of 44.9 cm and depth of seed placement for sorghum, chickpea & maize seed was found to be 2.5, 6.9 & 3.9 cm, respectively. The working width of seed ferti drill was found to be 135 cm with a depth of sowing was observed to be 2 to 10 cm and that width of inter row cultivator was found to be 90 cm with a depth of inturculture operation was observed 6 to 10 cm. The average draft requirement of the seed ferti drill was 198.1 kg and it was recorded 167.1 kg for inter row cultivator at an average speed of 3 km/h. The percentage of the visible seed damage was found in the range of 1 to 1.5 per cent in seed ferti drill calibration. Fuel consumption for sowing operation and intercultural operation was found to be 4.51 l/ha and 3.21 l/ha, respectively. The average tractor wheel slip for seed ferti drill and inter row cultivator was found to be 6.68 and 6.78 per cent, respectively. The effective field capacity, theoretical field capacity and field efficiency for seed ferti drill was found to be 0.403 ha/h, 0.485 ha/h and 83.09 per cent, respectively. The effective field capacity, theoretical field capacity and field efficiency for inter row cultivator was found to be 0.428 ha/h, 0.469 ha/h and 91.26 per cent, respectively. The average weeding efficiency, plant damage and performance index of machine was found to be 90.02 per cent, 1.4 per cent, respectively. The average germination percentage was observed 84.77, 93.80 and 79.81 per cent for sorghum, chickpea and maize crops, respectively. The cost of operation for sowing was found to be Rs.1202.20 per hectare and the cost of interculturing operation was found to be Rs.922.86 per hectare. The overall performance of the small tractor operated seed ferti drill cum inter row cultivator was found to be satisfactory.
Description
There is need for high capacity machines for custom hire services. For precise application of seed and fertilizer, mechanically metered seed drill and seed-cum- fertilizer drill operated by animal and tractor have been developed and are being manufactured to suit specific crops and regions. There is a high demand for small tractor for the small farm along with matching implement small tractor operated seed ferti drill is an urgent need. Weeding operation is one of the important intercultural tillage operation which control unwanted plants between the rows that consume more fertilizers and reduces the crop yield. Controlling weed is one of the serious problems faced by the farmers.
