Egypt. The main objective of this research was to investigate the response of
sole and relay intercropping cotton and wheat to the effect of sowing dates
and ridge width on cotton yields in Abo Hussein Village, Abo Kebeer district,
Sharkia Governorate, Egypt. The experiment was carried out in a strip plot design
with four replications. The vertical plots were occupied with three sowing dates.
The horizontal plots were assigned to three ridge width. Sowing on 15th March
significantly affected (p<0.05) number of days to first flower opening and
plant height of sole and relay intercropping cotton and number of fruiting branches/plant,
number of opened bolls/plant, boll weight, seed cotton yield per plant and feddan
and lint cotton yield/fed of sole cotton and resulted in the highest values
in both seasons. Sowing relay intercropping cotton on 1st April significantly
affected (p<0.05) number of fruiting branches/plant, number of opened bolls/plant,
boll weight, seed cotton yield per plant and feddan and lint cotton yield/fed
and produced the highest values in both seasons. Sowing sole or relay intercropping
cotton on wide ridges significantly affected all studied traits and produced
the highest values in both seasons. It can be concluded that, in order to maximize
seeds and lint cotton yields/fed of sole cotton, it must be sown in 15th March
on ridges with width of 100 cm. However, for maximization of seeds and lint
cotton yields/fed of relay intercropping cotton, it must be sown in 1st April
on ridges with width of 100 cm.]]>El-Nour, M.S.A., M.A. Saeed and M.A. Morsy,20007812191231Ali, S.A. and A.E. El-Sayed,200179221232De Wit, C.T. and J.P. van den Bergh,196513212221El-Zik, K.M., P.M.
