Taschenbuch. Zustand: Neu. Neuware -Growth, development and yield of soybean are a result of a variety's genetic potential interacting with environment and farming practices. Experiments were carried out in two locations for determining the resistance of some soybean genotypes to the cotton leaf worm. Beside that, identification of molecular genetic markers linked to insect resistance was also done. An attempt was done to get some new resistant hybrids through execution hybridization between these cultivars. Plant height, numbers of branches and pods per plant and seed yield per plant were decreased significantly by the infestation of cotton leaf worm (Spodoptera littoralis) as compared with soybean plants grown in Giza region (non ¿ stressed treatment). The results of SDS-PAGE revealed a total number of 21 bands with molecular weight (MW) ranging form about 319.63 to 15.568 KDa. 5 primers showed specific ISSR markers for cotton leaf worm with 6 positive markers for cotton leaf worm resistance appeared in the resistant genotypes, while 2 negative markers for susceptibility for cotton leaf worm were present in the susceptible genotypes.Books on Demand GmbH, Überseering 33, 22297 Hamburg 104 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The obtained data indicated that ear length and diameter, numbers of rows/ear and kernels/row and 100-kernel weight were increased significantly by decreasing plant density from 35 000 to 17 500 plants/acre. On the other hand, increasing maize plant density from 17 500 to 35 000 plants/acre by decreasing distance between hills from 40 to 20 cm apart increased significantly grain and stover yields/acre. Harvest index was decreased from 22.25 to 21.00% in the 1st season and from 22.14 to 20.04% in the 2nd season by widening distance between maize plants from 20 to 40 cm apart, respectively.Leaf area index was correlated positively and significantly with stover yield/acre in the two growing seasons. Positive but insignificant correlation coefficients were found between leaf area index and each of grain yield/acre and harvest index in the two growing seasons. While, Leaf area index was correlated negatively and significantly with each of ear weight, length and diameter and number of kernels/row in both seasons and with 100-kenel weight in the 2nd season.Books on Demand GmbH, Überseering 33, 22297 Hamburg 100 pp. Englisch.

Taschenbuch. Zustand: 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. Zustand: Neu. Neuware -The study aims to possibility of increasing total monetary economic return for farmers and encourage them to grow cotton by intercropping with cash crop like maize. Mixed intercropping pattern gave the highest seed cotton yield/acre than the other intercropping patterns. Maize variety S.C.30k09 had lower adverse effects on number of bolls/plant, seed cotton yield per plant and per acre than maize variety T.W.C.310. Doubling distance between hills of maize plants from 35 to 70 cm gave higher means for each of number of bolls/plant, seed cotton yield per plant and per acre. Number of maize plants under intercropping patterns played a major role of intercropped maize yield. Net return of intercropped maize with cotton varied between Euro 243.1 and 603.8 per acre as compared with recommended solid planting of cotton (Euro 301.7). Mixed intercropping pattern gave the highest value of net return (Euro 603.8) when maize variety S.C.30k09 was grown in wide distance between hills (4 plants at 70 cm apart).Books on Demand GmbH, Überseering 33, 22297 Hamburg 180 pp. Englisch.

Taschenbuch. Zustand: 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.
