Title

Donald J. Boquet Agronomy Journal 2005. doi:10.2134/agronj2005.0279
Other claims from this paper (9)
- Intervention effect Increasing plant density decreased lint yield of irrigated cotton.
- Intervention effect Increasing plant density had no effect on yield of rain-fed cotton.
- Intervention effect Increasing plant density decreased boll number per plant and individual boll weight of irrigated cotton.
- Intervention effect Increasing plant density had no effect on boll number per square metre of irrigated cotton.
- Intervention effect Yield components of rain-fed cotton were not affected by varying plant density.
- Intervention effect Plant density, N rate and row spacing affected cotton fiber properties, but the effects were small.
- Intervention effect Under irrigation, ultra-narrow row cotton yielded lower lint than wide-row cotton (771 vs 1069 kg/ha).
- Intervention effect Without irrigation, ultra-narrow row cotton yielded lower lint than wide-row cotton (377 vs 586 kg/ha).
- Observation Maximum lint yields of ultra-narrow row cotton were attained at 128000 to 256000 plants/ha and 90 kg N/ha.
