SPRING OAT - A CROP DEPENDENT ON CLIMATE AND TECHNOLOGICAL CONDITIONS

Abstract

The study analyzed the productivity and quality of the spring oat variety Ovidiu. The variety was cultivated within ARDS Lovrin, under non-irrigated cultivation conditions. Two experimental factors were analyzed – crop fertilization (with two graduations) and soil cultivation (with four graduations). Production was determined quantitatively at crop harvest. Regarding the main productivity elements: panicle length, number of grains/panicle, grain weight/panicle, straw length, TKW, HLW – these were obtained by analyzing a number of 50 plants for each experimental variant. The protein percentage was determined in the laboratory using the Kjeldahl method. Among the four types of soil cultivation practiced for the establishment of the spring oat crop, for the western area of ​​Romania the most efficient is the method of preparing the germinal bed with the heavy disc. By using this method, the costs of land preparation are reduced by 73%. The economic efficiency of disc tillage also derives from the higher yields per hectare obtained compared to the other three methods, the quality of the productions, and better storage and preservation of water in the soil.
