Field experiments were carried out to study the effect of different sources of organic manures and inorganic fertilizers on yield attributes and yield of groundnut at Krishi Vigyan Kendra, Tamil Nadu Veterinary and Animal Sciences University, Kattupakkam during Rabi 2014 and 2015. The experiments were laid out in split-plot design consisting of twelve treatments with 3 replications. The main plot consisted of Farm yard manure @ 12.5 t ha-1 (M1), Vermicompost @ 5.0 t ha-1 (M2), Fish pond silt @ 5.0 t ha-1 (M3) and Composted poultry manure @ 5.0 t ha-1 (M4) and sub plot consisted of 100 per cent recommended dose of fertilizers NPK (S1), 75 per cent recommended dose of NPK (S2) and 50 per cent of recommended dose of NPK (S3). Data on yield parameters viz., Number of pods plant-1, Number of kernels pod-1, 100 kernel weight (g), pod yield and haulm yield of groundnut (kg ha-1) were collected for different treatments. Results revealed that application of vermicompost @ 5.0 t ha-1 (M2) recorded significantly higher number of pods plant-1 (24 and 25 nos.), higher groundnut pod yield (2488 and 2549 kg ha-1) and higher haulm yield (4170 and 4279 kg ha-1) as compared to other organic manure treatment in both the season. Similar trend was observed in the case of number of kernel pod-1 also, whereas, the 100 kernel weight was not significant due to the application of different organic manure. In addition, application of recommended dose of 100 per cent NPK (S1) significantly recorded higher number of pods plant-1 (22.9 and 24 nos.), higher groundnut pod yield (2436 and 2490 kg ha-1) and higher haulm yield (4092 and 4190 kg ha-1) over 75 and 50 per cent of NPK levels in both the years. However, the interaction between organic manures and fertilizer levels were not significant on number of kernel pod-1, 100 kernel weight, pod yield and haulm yield of groundnut but highly significant on number of pods plant-1. The study showed that groundnut crop responded well in terms of yield attributes, pod yield and haulm yield by the application of vermicompost @ 5.0 t ha-1 and 75 per cent recommended dose of NPK fertilizers.
