Growth response, yield and yield components of upland cotton (Gossypium hirsutum L) as affected by rates and time of nitrogen application in the Nigerian savannah



Growth response, yield and yield components of upland cotton (Gossypium hirsutum L) as affected by rates and time of nitrogen application in the Nigerian savannah



Fertilizer Research 3(4): 399-409



Effects of N application rates and dates on growth, yield and yield components of upland cotton were studied in 1975-6. Four rates of N application (0, 26, 52 and 78 kg/ha) applied 3 or 8 wk after sowing were compared. Seed cotton yield components increased with increased N at least up to 52 kg N/ha with yield increases between 49 and 73%. Seed cotton yield was influenced by treatments mainly through boll number. Both CGR and fruiting were enhanced by N.
