A two-year study was carried out at Serw Agricultural Experiments and Research Station, A.R.C., Domiate governorate, Egypt, during 2015 and 2016 seasons to evaluate intercropping cowpea with suitable maize cultivar and its planting geometry for maximizing land usage and net return. The treatments were the combinations between three maize cultivars (SC 30K08, TWC 310 and TWC 352) and three maize plant distributions (one plant/hill distanced at 25, 50 and 75 cm between hills, respectively). Ridge width with maize plant distribution formed maize planting geometry (25 cm × 140 cm, 50 cm × 140 cm and 75 cm × 140 cm). These treatments were compared in a split plot distribution in randomized complete block design with three replications. Maize cultivar SC 30K08 had the highest grain yield and its attributes compared with the other cultivars in both seasons. Also, maize planting geometry 25 cm × 140 cm resulted in the highest grain yield and its attributes compared with the other planting geometries in both seasons. Ear length, ear weight, 100-grain weight and grain yield/fad were affected significantly by maize cultivars × maize planting geometry. Intercropping cowpea with maize cultivar TWC 352 had the highest seed yield and its attributes compared with those intercropped with the other cultivars in both seasons. Also, maize planting geometry 75 cm × 140 cm resulted in the highest seed yield and its attributes through growing two cowpea rows between maize hills compared with the other maize planting geometries in both seasons. Number of pods/plant and seed yield/fad were affected significantly by maize cultivars × maize planting geometry. LER and LEC values of the intercrops were much greater than 1.00 and 0.25, respectively, for all the combinations indicating less land requirements of intercropping system than solid culture of both crops. Growing one row of maize cultivar TWC352 in both sides of bed 140 cm width with cowpea two rows in middle of the bed increased land productivity and net return compared with solid culture of maize.展开更多

Nine quinoa genotypes including six Peruvian varieties (Amarilla Marangani, Amarilla Sacaca, Blanca de Junin, Kancolla, Salcedo INIA and Rosada de Huancayo) and three new accessions (QS14, QS16 and QS17-2) were compared in randomized complete block design with three replications. The results revealed that quinoa proved success in sandy soil with suitable grain yield under Egyptian conditions. QS17-2 accession stays only from 115 to 120 days in the field according to environmental factors and treated as short duration accession, while growth duration of the four varieties;Blanca de Junin, Kancolla, Salcedo INIA and Rosada de Huancayo, as well as, accessions of QS14 and QS16 were moderate. Amarilla Marangani and Amarilla Sacaca varieties had the longest duration genotypes. Amarilla Sacaca and Amarilla Marangani varieties, as well as, QS17-2 accession gave the highest grain yield compared with the other genotypes. The highest protein content in quinoa grains was 13.60%, which recorded from QS17-2 accession, while the lowest value (10.75%) was recorded by Blanca de Junin variety. Moreover, Salcedo INIA variety had the lowest saponins content in quinoa grains (0.07%) while QS16 accession recorded the highest content (0.22%). The economic evaluation gave a clear indicator of the lower farm prices of quinoa grains in Egypt (US$ 1000/ton), which gives a comparative advantage to Egypt in the MENA region for quinoa exportation.展开更多
