Study the effect of biofertilizers on productivity of some local cultivated varieties of rice from Gaurela-Pendra-Marwahi district of Chhattisgarh

The present experiment entitled “Study the effect of Biofertilizers on productivity of some local cultivated varieties of rice from Gaurela-Pendra-Marwahi district of Chhattisgarh” was conducted during Kharif season in year 2022-23 and 2023-24 at the village Parasi, block Marwahi, district (Gaurela Pendra Marwahi) under Govt. D.B. Girls P.G. College, Raipur, Chhattisgarh. The field experiment evaluated the impact of biofertilizers on the morphology, grain quality, and yield of two local rice varieties, Vishnubhog (V1) and Jeeraphool (V2), from the Gaurela-Pendra-Marwahi district. Employing a Factorial Randomized Block Design (FRBD) with 12 treatments and three replications, the experiment included two varieties (Factor A) and six organic treatments (Factor B): T₁ (FYM @10 t ha⁻¹ + BGA @1250 ml ha⁻¹), T₂ (FYM @10 t ha⁻¹ + Azotobacter @1250 ml ha⁻¹ + PSB @1250 ml ha⁻¹ + KSB @1250 ml ha⁻¹), T₃ (FYM @10 t ha⁻¹ + BGA @1250 ml ha⁻¹ + Biofertilizer consortia @1250 ml ha⁻¹), T₄ (FYM @10 t ha⁻¹ + Azospirillum @1250 ml ha⁻¹), T₅ (FYM @10 t ha⁻¹ + BGA @1250 ml ha⁻¹ + Azospirillum @1250 ml ha⁻¹), and T₆ (Control). Results indicated that Vishnubhog (V1) significantly outperformed Jeeraphool (V2) in panicle length, seed count per panicle, test weight, grain yield, and harvest index. Among organic treatments, T₂ exhibited the highest values for these parameters, closely followed by T₃, while the control (T₆) consistently recorded the lowest. These findings highlight the efficacy of integrated biofertilizer application, particularly T₂, in enhancing rice productivity and quality, supporting sustainable agriculture in Chhattisgarh.
