Effect of Sowing and Nitrogen Application Methods on Yield and Yield Components of Some Wheat Varieties

Abstract

Two field experiments were conducted at the Experiment and Research Center, Fac. Agric., Moshtohor, Benha Univ., during 2014/15 and 2015/16 seasons. The aim of this study was response to investigate the effect of three wheat varieties (Misr 2, Sakha 94 ,and Sids 12)to four planting methods (prodcasting, rows, hills on ridges and rows on beds ) and two application methods (prodcasting and drilling). The results indicated that:Misr 2 variety gave the highest values of plant height, spike length, No. tillers and spikes m -2 , No. spikelets spike -1 , weight of grains spike -1 , biological and grain yields fed -1 compared with the other varieties in the first and second seasons. planting by rows on bed method increased significantly plant height, spike length, No. otillers and spikes m -2 , No. spikelets spike -1 , weight of grains spike -1 , 1000-grain weight, biological and grain yields fed -1 compared with the other planting methods in the first and second seasons.Plant height, spike length, No. tillers and spikes m -2 , No. spikelets spike -1 , weight of grains spike -1 , 1000grain weight, biological and grain yields fed -1 increased significantly by prodcasting N application method in the first and second seasons.Plant height, No. tillers and spikes m -2 , No. spikelets spike -1 , weight of grains spike -1 , 1000-grain weight, biological and grain yields fed -1 were affected by the interaction between wheat varieties and planting methods in the first and second seasons except 1000-grain weight in the second season.Plant height, No. tillers and spikes m -2 , No. spikelets spike -1 , 1000-grain weight and biological yield fed -1 were affected by the interaction between varieties and nitrogen application methods in the first and second seasons except plant height and No. spikelets spike -1 in the first season. Plant height, No. tillers and spikes m -2 , No. spikelets spike -1 , biological and grain yields fed -1 were affected by the interaction between planting methods and nitrogen application methods in the first and second seasons except plant height, No. tillers m -2 , No. spikelets spike -1 and grain yield fed -1 in the first season. Also, plant height, No. tillers and spikes m -2 , weight of grains spike -1 , 1000-grain weight, biological and grain yields fed -1 responded significant to the interaction of the three involved factors (varieties x planting methods x N application methods).It could be concluded that under the conditions of the experiment, planting Misr 2 var by rows on bed method under proadcasting N application is recommended.

Impact of soil moisture-based irrigation, mulching, and nitrogen levels on wheat growth and yield in sub-tropical Jammu, India

“…It can be concluded that the increasing amount of nitrogen fertilizer consequently results in higher grain yield. These results are in conformity with El-Gizawy (2005) [6] ; Mosaad et al, (2013) [21] and Gazia and Abd EL Aziz (2013) [7] . Data pertaining to fig.…”

Eeffect of Nitrogen Fertilizer Levels and Irrigation Regimes on Yield and Yield Components of Some Wheat Cultivars

“…These results confirmed with those reported by Moussa and Abdel-Maksoud, (2004) where they found that, eight wheat cultivars differed significantly for number of spikes/m 2 , number of grains/spike, 1000grain weight, straw and grain yields. El-Gizawy, (2005) found that Gemmeiza 9 surpassed the other two cultivars in number of spikes/m 2 number of grains/spike, 1000-grain weight and grain yield. Gab Alla (2007) showed that, highly significant differences among 10 wheat genotypes in number of spikes/m 2 , number of grains/spike, 1000-grain weight, grain and straw yields and harvest index.…”

Response of Mustard (Brassica juncea L.) to Different Bio-Regulators under Varying Fertility Levels

“…The flower inducing domain of salicylic acid is important phytohormone that can enhance flowering in a variety of ornamental plants. Foliar application of brassinosteroid [4], salicylic acid [5] and cycocel [6] have been reported to be effective for enhancing mustard and other crops productivity by some worker under different environmental condition. It has been reported that these bio-regulators play vital role in greater participating of photosynthates toward reproductive sink thereby improving harvest index.…”
