Abstract

The present study aimed to evaluate the varieties and seeding rate yielding the highest productivity and net return for yield of the bread wheat crop. Analysis of variance and L.S.D Analysis approach was used to determine the effect of the experimental treatments applied in the experiment. Some criteria for the economic evaluation of agricultural experiments have also been calculated including net return and return of the invested pound. The results showed that when classifying the governorates of the Epypt according to the productivity of wheat crop for the average period (20142016) to nine production levels using the Duncan test. the governorates of the first. second. third. fourth and fifth rank were of high productivity. The results of the economic evaluation of the experiment showed that strain 1, strain 6 gave the highest productivity of feddan due to their superiority of the number of spikes and weight of 1000 kernels. Also. strain 1 gave the highest net return due to its high grain yield followed by strain 6. The optimum seeding rate was 300 grains/m 2 where it achieved the highest productivity per feddan. The current study recommends to expand in producing new wheat genotypes such as strain 1 and strain 6 and using seeding rate of 300 grains/m 2 for its high productivity and economic efficiency.

几种面包小麦基因型最佳播种率的经济评价
本研究旨在评价面包小麦产量和净收益最高的品种和播种率。采用方差分析和L.S.D分析法确定试验中各处理的效果。并计算了农业试验经济评价的净收益和投资收益等指标。结果表明,根据平均时期(2014 - 2016年)小麦作物的生产力,使用邓肯检验将埃及各省划分为9个生产水平。第一个省。第二。第三。第四和第五名是高生产率。试验经济评价结果表明,品系1、品系6因其穗数和千粒重优势,产量最高。也。品系1由于籽粒产量高,净收益最高,其次是品系6。最佳播种量为300粒/ m2,单日产量最高。目前的研究建议扩大生产新的小麦基因型,如品系1和品系6,并采用300粒/ m2的播种率,以获得较高的生产力和经济效益。
