Abstract:
A survey was carried out to study the various local practices developed for cotton culture throughout Israel, to locate the operations which could be deleted or replaced by other operations, and to determine the relative yield dependence on tillage and irrigation. Energy inputs consume about 1/6 to 1/4 of the gross returns for irrigated cotton, but their effects on yields could not be discerned. However, water application through precipitation and irrigation were found to have a large effect on yield. To reduce soil compaction hazards, energy input and labor costs, a new precision-minimum tillage procedure was developed and tested. Between the conventional and the new practice no significant differences in yield could be distinguished, provided there was no blockage of the planter by cotton stalks which caused an uneven stand. However, by precision-minimum tillage, energy input during autumn was cut by approximately one half, and the total mean energy input was reduced by one third. © 1984.
