The Analysis of Some Productivity Elements Obtained by Some Maize Hybrids Cultivated in Targoviste’s Plain

Abstract

Abstract In this work, five maize hybrids were analyzed in terms of productivity elements (number of rows of grains on the cob, mass of 1000 grains, yield in grains, production per hectare) cultivated in the pedoclimatic conditions offered by Targoviste’s Plain. The analyzed hybrids were Caussade, Clariti, KWS Kamelias, KWS Kinemas, Pioneer P0017, KWS 2376, hybrids of FAO 320-390 precocity group. The Pioneer P0017 hybrid was chosen as a control variant because of the frequent cultivation in the area. The study was conducted during the agricultural year 2017 in Băleni, Dâmboviţa County. The results obtained highlighted values between 14 and 18 rows of grains on the cob, the mass of 1000 grains presented values between 332.7 and 435.7 grams, and the yield in grains 87.16 and 89.9%. Regarding the production of grains per hectare, the analyzed hybrids achieved high levels of this parameter, namely from 9590 to 12846 kg of grains / hectare.
