Year: 2019
Type: article
Abstract: A field experiment was conducted at Agricultural College and Research Institute, TNAU, Killikulam (TamilNadu) during Rabi season (2018 -2019) to study the effect of organic and inorganic nutrients on growth, yield and soil fertility of groundnut variety TMV 13 in an Alfisolof Tamiraparani tract.The experiment was laid out in randomized block design (RBD) replicated thrice with ten treatments.Application of 75% STCR + Rhizobium @ 3 kg ha -1 + Humic acid @ 20 kg ha -1 + Poultry manure @ 3 t ha -1 (T 8 )produced significantly tallest plant (66.56 cm), number of branches plant -1 (7.94), days to 50% flowering (30.50), number of pods plant -1 (66.08), weight of pods plant -1 (70.95 g ), hundred kernel weight (36.02 g), pod yield (2938.17 kg ha -1 ) and haulm yield (8936.50 kg ha -1 ).Significant built up of organic carbon (0.69 % ), available N (278.32 kg ha -1 ), available P (16.53 kg ha -1 ) and available K (298.63 kg ha -1 ) were also registered with the application of 75% STCR + Rhizobium @ 3 kg ha -1 + Humic acid @ 20 kg ha -1 + Poultry manure @ 3 t ha -1 (T 8 ).
