Abstract EN
Six separate field trials were conducted at Shandaweel Agric.
Res.
Station (Sohag governorate), Egypt during 2012 season and repeated in 2013 season to study the effect of a new irrigation method with NPK rates and frequencies under two planting dates on yield and yield component of Egyptian cotton variety Giza90.
The obtained results revealed that sowing dates affected significantly all studied characters due to the variation in total amount of heat units in each date.
Early planting date in March increased yield and its component (number of sympodia branches/plant, number of open boll/plant, boll weight, seed cotton yields/plant and fed.) in both seasons.
In the first season, a new irrigation method, i.e.
alternative irrigation system resulted the high mean values for number of sympodia/plant, number of open boll, boll weight, yields per plant and per fed.
in the first planting date, but in the second date recorded high mean values for number of open boll and yield per plant.
Moreover, in the second season appearance high mean values for number of open boll in the first planting date and number of sympodia/ plant, number of open boll and seed cotton yield per plant in the second planting date.
Application of NPK fertilizer up to high rate 125% from the recommended NPK/fed.
significantly increased number of sympodia/ plant, boll weight and seed cotton yield per fed.
under the two planting dates in both season.
On the other hand, 100% from the recommended NPK/fed.
recorded high mean values for number of open boll and seed cotton yield per plant in the both seasons for each planting date.
Splitting fertilizers five times led to increase thenumber of sympodia/plant, boll weight and seed cotton yield per fed.
in the first planting date for 2012 and 2013 seasons as well as, number of sympodia/plant, seed cotton yield per fed.
and number of sympodia/plant, number of open boll in 2012 and 2013 seasons respectively, for the second planting date compared with the other treatments.
