Integration of organic as well as inorganic fertilizers for building nutrient balancing in rice based cropping pattern at AEZ 9 of Bangladesh

Intensification of agricultural land use along with cultivation of new cultivars has substantially expanded in Bangladesh. This has consequently led to a decline in soil fertility and the establishment of both macro and micronutrient deficiencies in crops. In light of this, a study was conducted to determine the best combination of organic and inorganic fertilizers to supplement micronutrient application for maximizing yield for the      T. Aman – Boro cropping pattern in AEZ 9. The study also aimed to assess the effects of organic and inorganic fertilizers on the growth, yield, and yield attributes of T. Aman and Boro rice. The findings indicate that, for Aman rice, 100% NPKS with Zn @ 2 kg ha^-1 and B application @ 1 kg ha^-1, and again 100% NPKS with Zn @ 4 kg ha^-1 and B application @ 2 kg ha^-1 to the Boro rice ensured the maximum grain yield in rice based cropping pattern. Regarding Aman- Boro rice cropping pattern, applying 100% NPKS+1t ha^-1 Vermicompost to the Aman rice and 75% NPKS + 2 t ha^-1 vermicompost to the Boro rice ensured the good rice yield in AEZ 9 of Bangladesh
