Jain. M.P | Sharma, A.K.
The field experiment entitled "Conjunctive use of fertilizers and manures in soybean-wheat sequence" was conducted during 2003-04 and 2004-05 in RED comprising of 16 treatments (8 treatments only chemical fertilizers and 8 conjunction of fertilizers and manures), each treatments replicated thrice. The studies on growth and yield attributing characters, grain and stover / straw yields and economics as affected by different treatments were conducted. The uptake of nutrient (NPK) by soybean under various treatments was also detennined. Grain yield data revealed that maximum yield in soybean (1823 kg ha-I in 2003 and 1952 kg ha-I in 2004) was attained in case of 50 % RDF through fertilizer+ 5 t FYM ha-I applied to each crop and in wheat (6113 kg ha-I in 2003-04 and 6049 kg ha-I in 2004-05) was recorded in treatment 75% RDF in soybean and 100% RDF in wheat trough chemical fertilizers. The minimum grain and straw yield in both the crops was noted in control. The net realization ha-I and C:B ratio in different treatments indicate that 50% of RDF through fertilizer along with 5 t FYM ha-I given to each crop provided good monetary return (Rs.40899) and C: B ratio (2.90). In situation of availability of only chemical fertilizers, 75% ofRDF to soybean crop and 100% RDF to following wheat crop which provided net return of Rs. 40922 ha-I. The minimum net returns (Rs. 27174 ha-I) and C:B ratio (2.45) was noted in control.
