Abstract
Two field experiments were conducted during 2018 and 2019 seasons at Sakha Agricultural Research Station, Kafr El Sheikh Governorate, Egypt to put the agricultural recommendations for the genotype [(Giza 89 x Karashinky) x Giza 86] x Giza 94 before releasing in agriculture as a new cultivar through find out the proper plant distributions of the recommended density (46,666 plant/fed) and the effect of nano Lithovit boron and mepiquat choloride (Pix) in reducing the negative effect of delaying sowing date through study the effect of seven plant distribution patterns and three foliar spraying treatments (without, nano Lithovit boron and Pix) as well as their interaction on the Egyptian new genotype [(Giza 89 x Karashinky) x Giza 86] x Giza 94. The experiment was laid out in a strip plot design with five replicates in the first season and four replicates in the second season, where the horizontal plots were assigned to seven plant distribution patterns as follows: Pattern (1): sowing cotton in ridges 120 cm apart on both sides in hills 30 cm apart, 2 plants/hill after thinning, pattern (2): sowing cotton in ridges 120 cm apart on both sides in hills 15 cm apart, one plant/hill after thinning, pattern (3): sowing cotton in ridges 90 cm apart on both sides in hills 40cm apart, 2 plants/hill after thinning, pattern (4): sowing cotton in ridges 90 cm apart on both sides in hills 20 cm apart, one plant/hill after thinning, pattern (5): sowing cotton in ridges 70 cm apart on one side of the ridge in hills 26 cm apart, 2 plants/hill after thinning, pattern (6): sowing cotton in ridges 60 cm apart on one side of the ridge in hills 30 cm apart, 2 plants/hill after thinning and pattern (7): sowing cotton in ridges 60 cm apart on one side of the ridge in hills 15 cm apart, one plant/hill after thinning.
