Abstract
Two trials to compare the effect of planting time on maize yields were conducted at Busia and Kakamega in the long rains of 1961. At both sites, early planting was significantly advantageous, resulting in a higher yield of maize. The higher yields obtained from early planting can be explained in part by the results of work conducted at E.A.A.F.R.O., Muguga. The application of farmyard manure and fertilizers maintained the yields of later planted maize, but not to the level that could be achieved both by early planting and application of fertilizers. The yield increases resulting from fertilizer application steadily declined with later planting.Later planting resulted in a progressively larger percentage of diseased cobs, especially after the fourth time of planting, and in a progressively smaller percentage of large cobs.
