Abstract
Five main factors affecting the productivity of agricultural air­craft, which are: topografical, technical, operational, climatic and pilot­age-wise factors. The present work concentrated on topographical fac­tors such as: field size, field run length, ferry flight distance and inter-plot ferrying distance, with the use of Mi-2 helicopter for spraying cot­ton plantations during 1992-93. The run length as a function of field size proved to be the high­est effective decisive factors, while the minor factor was interplot ferry. The ferry flight is situated between the mentioned two extremes, but more close to the interplot ferry.
