Abstract

ABSTRACT: The obtained of complete winter crops, i.e. clover; wheat and faba bean, the farmers tend to late the cotton planting date. This system led to negatively effect on cotton yield. Therefore, comparing the transplanting technique with the seeding method, we aim to change the strategy of cotton agriculture. Seven genotypes namely, Giza 86; G86 x 10229; Giza 88; Giza 92; Giza 93; [G.84 (G.70 x G 51b) ] x S62 and Australian were planted by using two methods, seed sowing and two transplanting date(1May and 1June). The earliness % significantly affected by planting methods, as so as the genotypes, while the interaction between them was insignificant for cotton yield. Also, the first fruiting node had the same reaction. The mean performance of early transplanting date 1 May (T2) exhibited high mean comparing with the late date 1 June (T3)and seeding method (T1). On the other hand, the first fruiting node decreases in transplanting method (early and late date) from 7.43 node for seeding method to 5.22 node for early transplanting and 5.95 node for late transplanting methods. However, lint percentage was not affected by the two methods. Early transplanting in first May (T2) increased seed cotton yield by 1.72   and 2.32 K/F compared with direct seed sowing (T1) and late transplanting in first June (T3), respectively.
