Response of Maize Hybrids to Different Nitrogen Applications Under Climatic Conditions of Plovdiv Region
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 4
Abstract
The field experiment was carried out on the Scientific-Experimental and Introductory Facility of the Department of Plant Growing at the AU – city of Plovdiv in the 2006-2008 periods. The experiment was performed by means of a block method with four replications; experimental field area - 25 m2. The effect of four rates of nitrogen (120, 160, 200 and 240 kg/ha) on elements of productivity and grain yield of two maize hybrids Florencia and PR35P12 were determined.The analysis of the results show that maximum number of row per cob, number of grains per row, number of grains per cob, length of cob, cob weight, weight of grains per cob, thousand grain weights and grain yield was recorded in application of 240 kg/ha when compared with other rates Based on the results we recommend the cultivation of PR35P12 hybrid under the Plovdiv region climatic conditions to be done with 240 kg nitrogen per ha-1.
