Traditionally the hand lever operated knapsack sprayer was used by the Indian farmers for spraying of pesticide, weedicide, fungicides, liquid chemicals etc. however it involves fatigue due to continuous hand lever operation results in the low efficiency. Now a days the power operated knapsack sprayers available in the market are being used for spraying operation in production agriculture but it is associated with more vibrations, noise levels causes the high level of fatigue during the operation hence labors are reluctant to use this types of sprayer. Also in the remote area due to unavailability of fuel and electricity there were lot of problems occurred in the agricultural operation. In order to overcome these problems solar cum hand operated Knapsack Sprayer was designed by using modern development techniques. Under this study performance evaluation was carried out in laboratory as per the Indian standard using different test rigs in testing center and field tests were carried out on different crops such as Okra and Bitter guard in the field. The field efficiency of using SPV, battery cum hand operated knapsack sprayer and Hand lever operated knapsack sprayer was 89.42 and 80.39 per cent, respectively and the solution required for spraying one ha field were found to be 498 litres and 512 litres, respectively. SPV, battery cum hand operated knapsack sprayer has two times greater field capacity than hand operated knapsack sprayer.
