Effect of Organic and Synthetic Fertilizer Management on the Yield and Growth Components of Basmati Rice in Western U.P., India

Abstract

The present investigation was conducted during kharif 2022 at the CRC of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) to studies the Effect of organic and Synthetic Fertilizer management on the yield and growth components of Basmati Rice in Western U.P. (India). The soil of experimental site was clay- loamy in texture, slightly alkaline, non-saline, low in organic carbon, N, P, and high in available K. DTPA extractable micronutrient were in high amount. Eleven treatments, viz., T1 (Absolutely Control), T2 (100:75:0 kg NPK ha-1), T3 (100:75:60 kg NPK ha-1), T4 (Only FYM @ 20 t ha-1), T5 (Only VC @ 20 t ha-1), T6 (50:37.5:30 kg NPK ha-1 + FYM @ 20 t ha-1), T7 (50:37.5:30 kg NPK ha-1 +VC @ 20 t ha-1 ), T8 (100:75:60 kg NPK ha-1 + FYM @ 10 t ha-1), T9 (100:75:60 kg NPK ha-1 + VC@ 10 t ha-1), T10 (50:37.5:30 kg NPK ha-1 + FYM @ 10 t ha-1) and T11 (50:37.5:30 kg NPK ha-1 + VC @ 10 t ha-1) were tested in RBD with three replication. The study revealed that application of T9 significantly improved the growth and yield attributes thus increasing the yield of rice over control with a corresponding increase of 61.2 and 34.5 percent in grain and straw yield of rice, respectively, although this treatment was found to be on par with T7 and T11. Thus, the inclusion of inorganic with organic sources of plant nutrients together helps to maintain yield stability, increasing the effectiveness of supplied nutrients, and creating favorable soil physical conditions.
