The parameters, such as plant height, number of tillers per meter square, number of leaf per tiller, leaf area index, dry matter yield, yield attributes and yield of upland rice were observed highest in chemically fertilized treatment. The highest grain yield (2.337 Mg ha-1) from chemical fertilizer application was at par with fresh and decomposed biogas effluent, yielding 2.189 Mg ha-1 and 2.050 Mg ha-1 grain respectively. The gross return (Rs. 47.43 thousand ha-1) and net return (Rs. 25.00 thousand ha-1) were highest in chemical fertilizer. The benefit-cost ratio (BCR) was the highest (2.28)...

The gross return (Rs. 47.43 thousand ha-1) and net return (Rs. 25.00 thousand ha-1) were highest in chemical fertilizer. The benefit-cost ratio (BCR) was the highest (2.28) in fresh biogas effluent, which was almost similar to decomposed biogas effluent (2.18) and chemical fertilizer (2.11). The organic matter content (2.716 %), available phosphorus (42.86 kg ha-1), and available potassium (46.49 kg ha-1) were significantly higher in fresh biogas effluent than the other and that were at par with decomposed biogas effluent. The total nitrogen content was the highest (0.1353 %) in decomposed biogas effluent and was statistically at par with the rest of the treatments.
