Abstract
Pig manure is a locally available source of manure which contains high nitrogen amounts and foliar applying it in rape increases growth and yield. The research was done with the objectives of determining leaf area index, plat height and dry weight of Brassica napus L. in relation to different application rates of pig liquid manure. All agronomic practices were merely done but not mentioned as they were not under the study. Lack of enough information on the application rate of liquid manure for a specific crop is still limited. So the main thrust of the project was to find the appropriate application rate of pig liquid manure on Brassica napus which will be used to supply the required nitrogen. Top dressing was done merely and recorded as it was done to determine application rate. It was done every fortnight every Monday with 40, 60 and 80mls used as application rates. Harvesting was done from the third week after transplanting to eighth week. The leaf area index, plant height and dry weight were significantly different (p<0.05) with the plants that received 80 mls having the highest recordings in all aspects. Rape plants respond very well in high nitrogen quantities so growth and yield were high. In a nutshell soil analysis should be a must before applying organic manure so as to know the nutrient status of the soil and thus helping farmers to make amends to reach the required quantities of nutrients needed by plants. So this project recommends farmers to undergo soil analysis test before applying organic matter.
