Abstract:
The insect pests cause significant damage to the chilli crop. There are 39 genera and 51 species of insects attacking chilli in the field and during the storage. Pesticides are critical inputs for crop production worldwide and are expected to continue to play a major role for the foreseeable future to protect most crop systems from the infestation of insect pests and diseases. A study was conducted in in research farm, UAS, Raichur, to study biometric and equipment parameters influencing development of portable knapsack boom power sprayer. The type and variety of crop influence the quantity of chemical solution recommended per unit area. The height of crop varied from 909 to 985 mm with an average value of 957 mm. leaf area index of crop varied from 1.41 to 1.52 with an average value of 1.48. The row to row spacing varied from 855 mm to 927 mm with an average value of 900 mm. The plant to plant spacing varied from 285 mm to 309 mm with an average value of 300 mm. The equipment parameters such as pump capacity, pressure setting, tank capacity, rated power and weight of sprayer without solution were considered for development of portable knapsack boom power sprayer.
