Summary

Eight trials, covering a wide range of conditions in Malawi, have assessed the effect of applying nitrogen (0, 45 and 90 kg. ha.−1), sulphur (0, 22, 45 kg. ha.−1), phosphorus (0, 15 kg. ha.−1) and boron (0, 0·63 kg. ha.−1) on growth and yield of cotton. A nitrogen × sulphur interaction was very highly significant at one site, and good responses to nitrogen were obtained at six sites. Phosphorus and boron gave significant increases at one site. Increased yields of seed cotton indicated that there is an overall need for a compound fertilizer to supply nitrogen, sulphur, boron and in some areas phosphorus.
