Integration of Fertilizer and Manure: Its Performance Under the System of Rice Intensification Md. Abdur Rahman Sarkar

The experiment was to observe the effect of integration of fertilizer and manure on the performance of Boro rice under the SRI method. The experiment included ten treatments of rice production method viz. conventional method (CM) with recommended dose of fertilizer (RDF); CM with cowdung (CD) @15t/ha; CM with CD @5 t/ ha+RDF; SRI+CD @15 t/ha; SRI+CD @10 t/ha; SRI+CD @ 10 t/ha+50% RDF; SRI+CD @ 5 t/ha+100% RDF; SRI+100% RDF; SRI+150% RDF; SRI+100% RDF+ biofertilizer. The results indicated that all crop characters except number of non-bearing tillers/hill, sterile spikelets/panicle and harvest index were significantly influenced due to integration of fertilizer and manure. The SRI method performed better than conventional method. Among the SRI, integration of fertilizer and manure and fertilizer more than 100% of the recommended rate produced the highest grain yield. The results showed that the best option for the cultivation of Surjomoni rice variety under SRI method during the Boro season was 10 t ha-1 cowdung with 50% of the RDF obtain the highest grain yield . This integration not only reduced the production cost but also had a long term impact on improvement of soil properties.
