Efficiency in Potato Growing with Irrigation in Dry Climate

摘要

Improvements were introduced in technology of potato cultivation under irrigation in the conditions of the Southern Urals steppes. Key elements of agronomical complexes aimed to cultivate the crop were developed in experiments. They provide control of light regime and feeding schedule, phytosanitary characteristics of seeds to gain different levels of the expected yield. We defined water consumption regime of the crop in ontogeny for regional conditions. On the result of multivariance evaluation we defined percent of impact of the examined factors on potato crop capacity. It was set out that if water and feeding regime of soil are combined in the optimum way the potato crop makes 49 tons per 1 hectar.
