The Effect of Planting Distances in Several Genotypes of Yellow Maize (Zea Mays l.)

Abstract

Abstract Two field experiments were carrid out in Abi Gharaq, Al-Masaleeb in Autumn season, 2020 and Spring season, 2021 in the fields of Technical college/Musayyib for finding out the effect of planting distances in several genotypes of yellow maize (Zea Mays L.). Five genotypes are used as parents and the first one of it is used in planting the second season and in three experimental units for both distancing and genotypes. The distances were (60cm, 70cm, and 80cm) among the species for each five species from each experimental unit (three experimental units) and the soil was structured for five genotypes. The characteristics of the crop and its ingredients (the average number of kernels in the plant, the average kernel height(cm), the average number of rows in a kernel, the average number of seeds in a row, the average number of kernel seeds, the average weight of 300 seeds (gm), and the average crop seeds for the plant (gm)/a plant) are studied for each experimental unit. The data are analyzed statistically for each characteristic according to variance analysis and using a least significant difference test (LSD) under the level of 5% for autumn and spring seasons using the standard design for agricultural experiments (RCBD). The results have shown the excess of the first density in most of the characteristics studied. As for the species, the results have shown the excess the of the first genotype over all other genotypes.
