Trials of spraying and cultural practices on cotton in Uganda. 1. Agronomic and spraying implications



Trials of spraying and cultural practices on cotton in Uganda. 1. Agronomic and spraying implications



Experimental Agriculture 9(2): 147-157



In a series of 4 trials at Serere in 1965-7, a preceding crop of late sorghum or beans following a ploughed-in ley did not decrease the seed-cotton yields of early cotton the following year, compared with the recommended practice of ploughing the ley 6 weeks before sowing, but yields were decreased by delay in ploughing to 2 weeks before sowing or by a 4-week delay in sowing. Yields were not increased by application of N following the ley.
