Abstract only

Environment has primary importance in obtai- ning high maize yields, as biological requirements of the crop must be fully meet. Maize places special demands on warmth, it flowers at relatively low temperature, and is comparatively drought-resistant. Feeding properties and technological values of maize greatly depend on the conditions of its cultivation. To obtain high and quality yield, the full set of management practices should be applied and optimal conditions established to ensure full realization of the variety's yield potential under specific soil and climatic conditions. Given the above, studies were conducted in 2001-2001 under the conditions of the lowland-foothill irrigated area of Azerbaijan. Trials were established on light-brown soils on a demonstration plot of the Crop Production, Genetics and Breeding Department of Azerbaijani Agricultural Academy (AAA) in- volving two new maize varieties Adkta-70 and Kyapaz. The study objective was to determine the response level of new maize varieties to the basic management practices, particularly to planting dates (three dates) and mineral fertilizers top-dressed during the vegetation period at the rate of N90 P90 R60 combined with the pre-plant application of 10 tons of manure and p30' During the vegetation period, phenology notes were taken, maize growth and development stages were observed, dry matter accumulation was measured and dynamics of stem growth were recorded, Grain yield, yield components and grain quality were measured and analyzed and the cost-effectiveness of the trial was estimated, Winter wheat was the maize predecessor during the years of the study, Maize was planted through single-grain sowing technique in 4 rep- lications, The harvest was done through the continuous plot-by-plot technique, As a result of the studies carried out under conditions of the lowland-foothill irrigated area of Azerbaijan, the optimal maize planting date (mid- April) and the optimal application rate ofN90P9OR60 combined with pre-plant application of 10 tons of manure + p 30 have been identified. The optimal planting date and fertilizer rates provided for 30- 40% increase in grain yield of the new maize varieties, Kyapaz has been found to be the most productive maize variety.
