Effect of Different Rates of NPS Fertilizer on the Yield Components of Cabbage (Brassica oleraceavar. capitates.)

Abstract

is known for its nutritional importance and it is rich in minerals and vitamins like A, B1, B2, and C. Among different factors application of fertilizer in different rata was affecting the productivity of cabbage. Therefore, field experiment was conducted in 2011 at Wolkite University at demonstration site with the objective of to evaluate the effect of different rate of NPS on yield and yield component of head cabbage. Filed experiment was conducted by RCBD design with three replication of the following treatment 0kg,60kg,120kg,180kg,240kgand 300 kg/ha|) of .Copen Hagen market variety of cabbage was used for the experiment. To analysis the effect of NPS rate the following data’s were taken and analiyised by manual scientific calculate. Application of different rate of NPS was a significant (p<0.05) on the yield component of cabbage. From the result the higher plant height (25.6 & 30.53, days of 50% headinitiation( 54 and 56.33), Days of 90% head maturity( 65 and 67.33), head height(12.8 and 14.47) , head weight( 0.933 and 1.06kg/ha), head circumference( 30.15 and 30.18) and head diameter( 12.16 and 12.06) was recorded at the rate of 300kg/ha and 180kg/ha respectively and intermediate result was recorded at the rate of 60kg/ha 120kg/ha and 240kg/ha whereas the lower yield attributer was recorded sole cropping.. From the result increasing the rate of NPS fertilizer was increase the yield attribute of cabbage and recommended to the local farmer to use 180kg/ha. However further investigation may be suggested to carried out on different soil types ,different location to come up with precise and comprehensive recommendation
