Effect of Integrated Application of Vermicompost and Inorganic Fertilizers on Yield and Yield Components of Bread Wheat in Adami Tulu Jido Kombolcha District of East Showa Zone, Ethiopia

A field experiment was conducted at Adami Tulu Agricultural Research Center during 2022 cropping season to evaluate the responses of vermin compost and inorganic fertilizers on bread wheat (Triticum aestivum). The experiment consists of eight treatments: T1= Control (without fertilizer), T2=50% RNP+4t/ha VC, T3= 50% RNP+ 8t/ha VC, T4=100% RNP, T5= 4t/ha VC, T6= 8t/ha VC, T7= 100% RNP+ 4t/ha VC, T8=100% RNP+8t/ha VC. The result revealed that grain yield affected by combined application of these two fertilizes. There are gradual changes in some major soil parameters have statistically affected by combined application of vermin compost and inorganic fertilizer. Accordingly maximum grain yield (4596.3kg/ha) was recorded from T2 where 50% recommended NP+4t/ha VC where as the lowest grain yield (2109.3kg/ka) was from control plot. Lastly partial budget analysis was also calculated to determine best treatment combination for future farther use. Accordingly maximum net benefit (155,870.50ETB) was obtained from T2 where 50% recommended NP+4t/ha VC was combined. Therefore this treatment was used as best treatment combination for this area, for this crop, it needed for large scale soil fertility management and increasing land productivity.
