Abstract
The present investigation was carried out at Elwady El Assiuty Experimental Farm, Faculty of Agriculture, AssiutUniversity during 2013/2014 and 2014/2015 seasons to study the effect of nitrogen fertilizer splitting on the productivity of six local bread wheat cultivars under sandy soil condition. Randomized complete block design (RCBD) using strip block arrangement with three replications was used. Cultivars under study viz. Giza-168, Misr-1, Misr-2, Sids-1, Sids-12 and Shandaweel-1 were arranged in horizontal strips, while splitting (3, 4, 5 and 6 times) nitrogen fertilizer treatments were allocated to vertical strips. The obtained results pointed out that the superiority was to Sids-1 cultivar in plant height and spike length in both seasons. Moreover, Sids-12 cultivar surpassed other studied cultivars in spike number m-2, biological and grain yields (ton ha-1) in both seasons. While, Misr-1 cultivar was superior the other studied cultivars in harvest index in both seasons. Here too, Giza-168 and Shandaweel-1 had the highest content of chlorophyll in both seasons. Also, the obtained data showed that 1000 kernel weight (g), biological and grain yields and harvest index increased when nitrogen fertilizer was split into five equal doses in both seasons. The previous findings were true with regard to chlorophyll content in the second season only. The tallest plants were obtained when nitrogen fertilizer was split into six equal doses in the two growing seasons. Moreover, the highest numbers of spikes m-2 were recorded when nitrogen fertilizer was split into at three equal doses in both seasons. Also, spike length and spikelets number spike-1 were increased when nitrogen fertilizer was split into four equal doses in both seasons. Moreover, the interaction between wheat cultivars and nitrogen fertilizer splitting had a significant influence on all studied traits in both seasons. The highest mean values of chlorophyll content and plant height were recorded from Shandaweel-1 and Sids-1 cultivars, respectively in both seasons when nitrogen fertilizer was split into six equal doses. Finally, the highest grain yield was obtained from Sids-1 cultivar when nitrogen fertilizer was split into five equal doses.
