- Abstract
At El-Serw Agriculture Research Station, Damietta Governorate, Agricultural Research Center, Egypt, over the two succeeding summers of 2019 and 2020, two field experiments were undertaken. The experiment was done in a separate location “low and medium salinity soil and each location was consisted of three planting dates (15th March, 15th April and 15th May). In addition, cutting dates, i.e., (cuts were taken after 40, 50, and 60 days for each location) were distributed in a randomized complete block design (RCBD) inside the sowing date plots in every location with three replications. Results indicated that highest values of growth characters, total fresh and dry weigh per feddan (one feddan equal 4200 m²) of cowpea were resulted under the low level of salinity soil (3.35 dSm-1 over both seasons) in both seasons in all studied sowing dates. Sowing cowpea on 15th May optimizing all studied seed characters. On the other hand, the lowest values of seed characters of cowpea were recorded due to early sowing date on 15th March in both growing seasons. Results also showed that, increasing number of days to cut cowpea forage up to 60 days increased productivity of cowpea under low and medium levels of soil salinity at the three studied sowing dates in both seasons. So, sowing cowpea on 15th of May and cutting plants every 60 days in order to maximizing productivity of cowpea under soil salinity stress to meet climate changes and environmental stress.
