| 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. | ||||
