SUMMARY
Field experiments were conducted at Agriculture Farm, A.R.S., Navgaon, Alwar during two consecutive seasons viz., Kharif 2019 and Rabi 2019-20 to evaluate the effect of biochar and fertilizer’s on cluster bean and it’s residual effect on wheat. The experiment was laid out in randomized block design with 7 treatments and three replications. The results revealed that the application of 100% RDF + 15q biochar in cluster bean recorded highest in all growth and yield parameters in both crops. In cluster bean, the maximum grain (14.72 q/ha) and straw yield (36.31 q/ha) were recorded under the treatment 100% RDF + 15q biochar, which were 17.26 & 11.67% higher over 100% NPK alone in grain and straw yield, respectively. The residual effect of treatments also observed significant in wheat, the maximum grain (42.60 q/ha) and straw (63.80 q/ha) were recorded where 100% RDF + 15q biochar
treatment applied in previous crop, which were 10.46 & 10.13% higher over 100% NPK alone in grain and straw yield, respectively. On the other hand the lowest values of grain and straw yield were obtained from control treatment. Similar trend was also recorded in plant height, 1000 grain weight in both crops. Similarly, the direct and residual effect of biochar on N,P,K content in grains and straw as well as total uptake were also recorded higher with the application of 100% RDF + 15q biochar in cluster bean.
