Development of Solar, Battery cum Hand Operated Knapsack Sprayer

In India most of the farmers are marginal land holders and traditionally they use hand lever operated knapsack sprayer, but it involves fatigue due to continuous hand lever operation and resulted in to the low efficiency. As we consider the remote area there is unavailability of abundant amount of fuel and electricity there were lot of problems occurs in the agricultural operation considering all this problems solar, battery cum hand operated knapsack sprayer was developed considering the available literature, functional requirement and problems faced by farmers during spraying operation. The main aim regarding development of this sprayer was minimize the cost of spraying operation by use of solar energy, reduced drudgery of farmers and increase the field efficiency and uniformity in spraying operation.
