Abstract

This experiment was conducted at the University for Development Studies, Nyankpala campus experimental field to determine the effect of depth of placement of granular and briquetted NPK on growth and yield of maize. The treatments consisted of two factors laid out in Split plot design and replicated three times. Fertilizer treatments served as main plot factor with the levels being NPK briquette, Granular split, Extension recommended and No fertilizer. Depth of fertilizer placement was taken as sub plot factor with two levels,7 cm and 10 cm. Maize variety used was Opeaburo, a hybrid variety. The application of two briquetted NPK per plant at the depth of 7cm recorded the highest plant height, grain yield, leaf area index, days to 50% silking and tasselling, higher agronomic and nitrogen use efficiency. Farmer applying briquette fertilizer at the depth of 7cm will have superior advantage in terms of yield and cost. Further experiment should be conducted in developing equipment for briquette application in maize. Also the experiment should be repeated on farmer’s field at different agro ecological zones to evaluate the performance of briquette at these locations.
