Investigate the interaction between nitrogen fertilizer and irrigation on phonological and morphological properties in hybrid 704 of maize
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 16
Abstract
In order to investigate the interaction of irrigation at different levels of nitrogen fertilizer on phonological and morphological properties in single cross hybrids 704 of maize, an experiment was conducted as comminuted Crete at Agriculture and Natural Resources Research Centre of Ardabil with three replications. Factor A that irrigation was at four levels of (7, 9, 11 and 13 days once) and factor B was the consumption of nitrogen at four levels of (200, 300, 400 and 500 kg per hectare). During the growing season, a number of traits including yield and yield components and phonological traits were assessed. Results showed that there was significant difference at 1% and 5% level between different levels of irrigation in terms the number of grain per row, depth of grain, cob percentage, moisture percentage, plant height, the number of leaf above the corn and also leaf area of the maize. The main effect of different levels of nitrogen in terms of yield, number of grain per row, number of leaves above the corn and grain row number was significant. There was also significant difference between nitrogen and irrigation in terms the number of row per kernels and maize leaf length and area at the 1% level. Results of mean comparison showed that the highest yield was related to the levels 400 and 300 kg per hectare nitrogen and irrigation every 9 days once in most traits had the highest value. The main and interactions effects of studied factors were non-significant in all morphological specifications.
