Plant Density, Nitrogen Fertility and Variety Recommendation for Maize Production in Semi-coral Environment of Pemba, Zanzibar


The optimum maize variety for the del crop on Pemba Island was determined through an experiment, and recommendations for optimised plant density and nitrogen fertiliser were made for the types that were put to the test. Three enhanced varieties (Staha, Situka, and TMV-1) were planted in opposition to the regionally cultivated variety JKU. Other treatments included three plant densities (44,444; 53,333 and 66,666 plants/ha) and four nitrogen rates (23, 46, 70, and 90 kgN/ha). The treatment sources of variation had a considerable impact on the growth and production of the maize crop (varieties, densities, and fertiliser rates). Between the best and worst performing types, there was a yield gap of about 69%. Increased nitrogen fertility led to a yield differential of up to 32.9 percent, while enhanced spacing led to an increase in yield of up to 28.8 percent. The variety Staha, cultivated at a spacing of 75 cm 20 cm, generating a plant population of 66,666 ha-1; and the usage of nitrogen at 70 kgN/ha are recommended for the best maize yields in the area. The optimal practise is to simultaneously optimise all three variables.
