The book will serve as a reference document for the researchers working in cropping systems particularly cereal based cropping systems. The experiment consisting of seven treatments was laid out in randomized block Design with five replications. Seed, straw and biological yield of mungbean increased with progressive increase in fertilizer dose. The pooled grain yield was recorded highest in T5 (1291 kg per ha). Highest grain, straw as well as biological yield of wheat was recorded in T5 during both the years. Pooled grain yield was recorded highest in T5 (2950 kg per ha), at par with T7 (2906 kg per ha) and T4 (2896 kg per ha) and significantly superior over rest of the treatments. Protein content was found highest in treatment T7 (100% RDF) with the value of 11.7% during both the years of experimentation. Maximum net returns were obtained in T7 during first and second year, respectively. The available N and K in soil increased due to the application of T2+75% RDF (T5), during both the years of study.
