Taschenbuch. Etat : Neu. Neuware -The study aimed to investigate the effect of some abiotic stresses on some vegetative growth characteristics of soybean (Glycine max (L.) Merr.) throughout growing ten soybean genotypes under sandy and saline soils conditions and water stress by skipping one day of drip irrigation under sandy soil conditions from flowering stage up to harvest. As a result of salinity, plant height, numbers of green leaves and branches/plant, as well as, leaves fresh weight decreased considerably as compared to sandy soil condition over all soybean genotypes with a reduction of 54.6, 67.7, 54.1 and 75.4%, respectively. Highly significant differences among soybean genotypes were obtained under sandy and saline soil conditions for all the studied vegetative growth characteristics except for plant height under sandy soil condition in 1998 season.Combined data of 1999 and 2000 seasons, showed significant differences among soybean genotypes for total dry weight at 45 days from sowing and for all the studied vegetative growth characteristics at 90 days from sowing and for most the studied yield components except for biological, pods and seed yields/acre, seed yield/m2 and seed yield/plant.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The study aims to increase intercropped soybean and maize yields. Intercropping pattern 2:4 (H) gave the highest seed yield/acre as compared with those of normal population of 2:4 (N) and other patterns. Soybean variety (Giza 22) had higher values for all studied soybean parameters than Giza 111 variety. All studied parameters of intercropped soybean were increased by doubling distance between hills of maize plants from 30 to 60 cm under intercropping patterns. Leaf area and yield/plant of intercropped maize were higher than those of solid maize under the same density of maize in the ridges. Intercropping pattern 2:2 (N) gave the highest grain yield/acre as compared with the other intercropping patterns. Wider distance between hills of maize plants (60 cm apart) gave higher values for all studied maize characters. Increasing soybean plant densities under intercropping patterns (2:2 'H' and 2:4 'H') caused significant increments in soybean yield/acre and land equivalent ratio without significant reduction in maize yield/acre. Net return of intercropped maize with soybean varied between Euro 193.7 and 320.1 per acre as compared with recommended solid planting of maize (Euro 202.6).Books on Demand GmbH, Überseering 33, 22297 Hamburg 184 pp. Englisch.
