 ABSTRACT

Field experiments were conducted during kharif 2010 and 2011 at Zonal Agricultural Research Station, Mandya to study the effect of farmyard manure and bio-digester liquid manure on the performance of aerobic rice. Soil was red sandy loam in texture, low in organic carbon (0.38 %) and available nitrogen (215.5 kg ha-1), medium in available P2O5 (26.2 kg ha-1) and K2O (162.3 kg ha-1). Treatment consisted of three levels of FYM (7.5, 10 & 12.5 t ha-1) and four levels of bio-digester liquid manure equivalent (BDLME) to (75, 100, 125 & 150 kg N ha-1) and compared with recommended practice (FYM 10 t + 100:50:50 N:P2O5:K2O kg ha-1) and absolute control. It was laid out in Randomized Complete Block Design with three replications. Significantly higher total nitrogen, phosphorus and potassium (118.1, 27.9 and 92.0 kg ha-1, respectively) were taken up by the crop with the application of FYM 12.5 t + BDLME to 150 kg N ha-1. However, it was on par with FYM 12.5 t + BDLME to 125 kg N ha-1 (115.2, 26.9 and 90.8 kg ha-1, respectively) and recommended practice (FYM 10 t + 100:50:50 N:P2O5:K2O kg ha-1) (124.2, 29.4 and 96.9, respectively). Higher net returns and B:C ratio (Rs. 28,355 ha-1 and 2.35, respectively) was received from FYM 12.5 t + BDLME to 150 kg N ha-1 and it was followed by FYM 12.5 t + BDLME to 125 kg N ha-1 (Rs. 28,075 ha-1 and 2.37, respectively).
