ECONOMIC EVALUATION FOR THE OPTIMUM SEEDING RATE FOR SOME BREAD WHEAT GENOTYPES

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.
