Abstract
This research was carried out at a private farm located at Qaha, Qalyubia Governorate , Egypt during the two successive summer seasons of 2018 and 2019 to evaluate 40 treatments which were the combination between four plant densities,i.e., sowing at 5 cm on one row, 5 cm on two rows,10 cm on one row and 10 cm on two rows and ten genotypes,ie., (Nebraska (G1), Giza 3 (G2), Giza 6 (G3), DB-5-486 (G4), DB-5-487(G5), DB-5-489(G6), DB-2-435(G7), DB-5-485(G8), DB-7-4(G9) and DB-7-31(G10), for dry seed yield and seed quality of dry bean. These treatments were arranged in a split plot in a complete block design with three replications. Plant densities were randomly distributed in the main plot and genotypes were randomly arranged in the sub plot. Resylts showed that The interaction between sowing at 10 cm on one side and G8 significantly increased fresh weight, dry weight/ plant, total chlorophyll in leaf tissues, number of seeds/ pod, 100 seed weight and yield / plant in both seasons. The interaction between sowing at 5 or 10 cm on two sides and the genotype G1 or G8 gave the highest values of total yield /fed., while the interaction between sowing at 5 cm on one row and G3 gave the lowest total yield /fed. (0.781 ton/fed.) as average two seasons. The high yielding genotypes were G8, G1and G6 over all environments. Also, data show that six insect species belonging to six families and four orders were recorded. The orders could be arranged ascending according to their general relative densities during the two successive seasons of study as follows: Lepidoptera (3.63 %), Hemiptera (7.50 %), Diptera (40.28 %) and Homoptera (48.59 %).
