| Abstract | ||
| Two separate field experiments were conducted during 2019 and 2020 seasons, at Mallawi region, Minia Governorate, Egypt, to study the effect of two planting date, four planting patterns and three NK fertilizer levels on yield and yield components of Egyptian cotton (Gossypium barbadense, L.) promising hybrid cotton (CB58 X Giza 90). The results could be summarized as follows: Planting date at 20th March was significantly increase of No. of fruiting branches plant-1, No. of open bolls plant-1, Boll weight, Seed index, Lint (%), Seed cotton yield plant-1, Seed cotton yield fed-1 in both seasons. Whereas, planting date at 20th April were significantly increase of Plant height, in two season. Regarding planting patterns was significantly effect on plant height, No. of fruiting branches plant-1, No. of open bolls plant-1, Boll weight, Seed index, Lint (%), Seed cotton yield plant-1, Seed cotton yield fed-1 in the both seasons. Concerning NK fertilizer levels had a significant effect on plant height, No. of fruiting branches plant-1, No. of open bolls plant-1, Boll weight, Seed index, Lint (%), Seed cotton yield plant-1, Seed cotton yield fed-1 in the both seasons. Boll weight, seed index and seed cotton yield fed-1 in the first season and seed cotton yield plant-1 in the second season were affected by the interaction between planting date and planting patterns. Moreover, plant height and No. open bolls plant-1 were affected by the interaction between planting date and NK fertilizer levels in the first and second seasons, respectively. While, plant height and No. open bolls plant-1 were affected by the interaction between planting patterns and NK fertilizer levels in the first and second seasons, respectively. Regarding the interaction effect, among planting date, planting patterns and NK fertilizer levels were significant differences of No. fruiting branches plant-1 in the first season only. It can be concluded that early planting, 130 cm bed width + 30 cm hill space planted in two sides and fertilized by 75 kg N + 48 kg K2O fed-1 under the conditions of the experiment. | ||
