- Effects of Compound D and Ammonium Nitrate Fertilizer Application Rate on Growth and Yield of SC513 Maize Variety
- Abstract
-
The most essential crop to use as food, feed as well as income generation worldwide is maize. As
a result, proper management should be practiced to boost production. This research was done at
Mushandi Home Farm in Macheke. It was aimed at investigating the effects of compound D in
combination with ammonium nitrate fertilizers application rates on growth and yield of maize
variety SC513. A randomized complete block design with four treatments of compound D and
ammonium nitrate and a control with no fertilizer was used. The fertilizer treatment rates were
0.0kg/ha, 200kg/ha, 350kg/ha, 400kg/ha for compound D and 0.0kg/ha, 200kg/ha, 300kg/ha,
400kg/ha for ammonium nitrate. These treatments were replicated three times to overcome
variation due to differences in the soil characteristics and location on the slope. Maize stem height
and leaf length were measured in week 2, 3 and 5 whilst cob length was measured in R1, R2 and
R3 development stages and grain weight was weighted after harvest and drying. Data on mean
plant height, cob length, leaf length, and yield were collected, recorded and analyzed using a oneway ANOVA. Results showed that fertilizer rates significantly increased the growth and yield of
maize variety SC513. An application rate of 400kg/ha produced the highest stem height (32.1cm),
leaf length (48.93 cm) in the 5th week, cob length (25.17cm) in R3 development stage and grain
weight (30.89kgs/9m2
). An application rate of 300kg/ha of fertilizer was recommended for SC513
in this study. - Date
