INFLUENCE OF CULTIVATION TECHNOLOGY ON THE MAIN ECONOMIC EFFICIENCY INDICATORS IN GRAIN MAIZE

Abstract

The value of the main economic efficiency indicators is directly influenced by the value of the main production and by production costs. In the maize hybrid PR 35 P 12, the variant b₄c₆ (N₁₃₅P₁₃₅K₁₃₅ – 2 mechanical weeding + 2 manual weeding) has proven the most efficient due to the yield of 93.47 q/ha, i.e. a production of 5,608 RON/ha, production costs of 3,687 RON/ha, with a production cost of only 0.39 RON/ha, supported by a profit rate of 52.10%. The yield in grain maize depends on the genetic material of the hybrid, on the fertiliser rate and on weed control methods. Grain maize cultivated under favourable climate conditions and with proper technology can produce over 100 q/ha standard grains and ensure profitable incomes for the farmers. The total profit in profitable variants range between 37.70% (b₄c₆) and 3.03% (b₁c₆). In the variant b₂c₁ there are losses of 489 RON/ha. The profit rate points out the efficiency of certain experimental variants. The variants with a profit rate of over 30% are recommended for production (b₄c₆, b₄c₅, b₄c₃, b₄c₄, b₃c₆, b₄c₂).
