Abstract

Studies were conducted to evaluate the effect of enriched farm yard manure and fertilizer levels on yield and economics of aerobic rice. Results showed that the application of 125:62.5:62.5 NPK kg ha-1 significantly enhance root weight (6.01 g) as compared to A2 i.e. 100:50:50 NPK kg ha-1 (5.45 g) however, it was at par with A3 i.e. 75:37.5:37.5 NPK kg ha-1 (5.15 g). In fertilizer level A1 i.e. 125:62.5:62.5 NPK kg ha-1 root length was significantly long (22.26 cm) however, it was at par with A2 i.e. 100:50:50 NPK kg ha-1 (20.80 cm) and A3 i.e. 75:37.5:37.5 NPK kg ha-1 (20.56 cm).

Efficiency to use water differ significantly due to fertilizer levels and method of application of manures. Higher water use efficiency (46.33 kg ha-cm-1) was noticed in A1 i.e. 125:62.5:62.5 NPK kg ha-1 which was at par with A2 i.e. 100:50:50 NPK kg ha- 1 (44.63 kg ha-cm-1) than A3 i.e. 75:37.5:37.5 NPK kg ha-1 (38.42 kg ha-cm-1). Spot application of enriched manure was significantly higher WUE (46.64 kg ha-cm-1) which was at par with enriched manure (44.02 ha-m-1), spot application of manures and fertilizer (42.00 ha-cm-1) and separate application of manures and fertilizer (39.57 ha-cm-1).
