Title: Maize Response to Method and Rate of Manure Application
Issue Date: 31-Dec-1999

Abstract: African Crop Science Journal, Vol. 7. No. 4, pp. 407-413, 1999 Maize Response to Method and Rate of Manure Application Code Number: CS99031 ABSTRACT: Field experiments to determine the effect of solid beef manure application method and rate on maize grain yield and maize dry matter yield were carried out in Chinyika Resettlement Area (CRA) in Zimbabwe in the 1996/97 and 1997/98 seasons. Four rates of manure (5, 10, 20, 30 t ha-1) were applied using two methods: broadcasting and banding laid out as a 4 x 2 factorial in a randomised complete block design with three replicates. Other treatments used were the extension recommendation, farmer practice, control and no basal fertiliser application. Maize plants were sampled at 5, 10 and 15 weeks after crop emergence (wace) for dry matter yield at one site. There were no significant effects of manure application method and rate on maize dry matter yield at 5 wace in both seasons. At 10 wace in the 1996/97 season banding resulted in significantly higher maize dry matter yield than broadcasting (P < 0.05). There was also a significant (P < 0.01) increase in dry matter yield with manure application rate. At 15 wace there were no significant effects of manure application method on maize dry matter yield in both seasons. Maize grain yield increased significantly (P < 0.001) with an increase in manure application rate at both sites in both seasons, and band application of manure resulted in higher maize grain yield than broadcasting at all manure application rates in both seasons. Band application of 30 t ha-1 manure resulted in the highest net benefit. Economic analysis indicated that 10 t ha-1 banded was the economical manure application rate in both seasons. The current general recommendation by extension agents is effective for dry - land maize production.
