Inter-cultivation and spraying are two important operations in crop protection techniques in order to ensure full healthy growth of crop from the time of germination to the harvest for a quality produce and thereby good returns. Cotton is a major fiber crops and soybean is one of the important oilseed crops of the world. The food grain losses due to weeds alone and only in India ranges as high as 40 million tons per year in addition to the losses incurred by pests/insects infestation. Furthermore, there is under-utilization of tractor due to comparatively larger tread width of tractor tyres rendering it inaccessible in soybean and cotton due to their short crop row spacing. A tractor drawn inter-cultivator cum sprayer for soybean and cotton was thus developed to carry out inter-cultivation and spraying operation simultaneously. The test results revealed the effective field capacity, field efficiency, weeding efficiency, plant damage and spray application rate of 0.631 ha h-1, 85.32 %, 86.12 %, 5 % and 297.76 l ha-1 respectively for soybean at a forward speed of 3.30 km h-1; and of 0.733 ha h-1, 81.56 %, 84.87 %, 3.06 % and 334.50 l ha-1 respectively for cotton at a forward speed of 2.50 km h-1.
