|Abstract:||An i n v e s t i g a t i o n e n t i t l e d , " E v a l u a t i o n of tnanurial v a l u e of biogas p l a n t s l u r r y with maize as a t e s t c r o p on medium b l a c k s o i l " was l a i d out in a f a c t o r i a l randomized b l o c k design with t h r e e r e p l i c a t i o n s at t h e A g r i c u l t u r al C o l l e g e Farm, Pane during Kharlf, 1987. There were four l e v e l s of biogas p l a n t s l u r r y v i z . , 0, 5, 7.5 and 10 t o n n e s / ha and t h r e e l e v e l s of n i t r o g e n v i z . , 0, 50 and 100 kg N/ha under study. The maize g r a i n y i e l d was s i g n i f i c a n t l y i n c r e a s ed w i t h i n c r e a s e d l e v e l s of s l u r r y a p p l i c a t i o n . The s t o v er yield showed significant improvement due to different levels of slurry application as compared to control. N, P and K content of maize grain and stover, crude protein content of maize grain and N, P and K uptake by maize grain and stover and total uptake of these nutrients was significantly increased with the increased levels of slurry application. Important physlcoijchemical and biological properties of the soil showed significant improvement with increased levels of applied slurry. Grain yield of maize was significantly increased with increased levels of nitrogen application. The application of 50 and 100 kg N/ha were on par but increased the stover yield significantly over control. The N, P and K content of grain and stover, crude protein content of grain and uptake of N, P and K was significantly more with increased levels of nitrogen application. Nitrogen application showed the favourable influence on physico-chemical and biological properties of the soil. The grain and stover yield of maize obtained at 7,5 tonnes/ha of slurry was equivalent to that of 100 kg N/ha application. Therefore, it would be advisable to use 7.5 tonnes/ha of slurry instead of applying 100 kg N/ha through urea. pages .. 83|
