ABSTRACT
Rice productivity in Odisha, particularly in districts like Gajapati, remains low due to abiotic stresses
and inefficient fertilizer use. To address this, site-specific nutrient management (SSNM) and tools like
the Rice Crop Manager (RCM) have been introduced to optimize nutrient application based on field-
specific conditions. In the light of above facts, the present study was laid out in split plot design with
three main plot treatments (cultivars) viz., Bina Dhan 11, MTU 1010 and MTU 1156 as well as three
subplot treatments (target yield based nutrient management) viz., RDF, RCM-based nutrient management
for a target yield of 6 t/ha and RCM-based nutrient management for a target yield of 7 t/ha which were
replicated thrice. The results revealed that MTU 1156 recorded the highest tiller number, dry matter
accumulation, grain and straw yield, performing significantly better than Bina Dhan 11. RCM-based
nutrient management targeting 7 t/ha resulted in superior growth and yield attributes compared to
RDF, highlighting its effectiveness in enhancing productivity. Therefore, it can be concluded that the
MTU 1156 with RCM-based nutrient management for a target yield of 7 t/ha is recommended for
maximizing growth and productivity of rice.
