Abstract:
To validate the effect of organic manures on growth and yield of green chilli (Capsicum annuum L.) a field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during December 2021- June 2022. The experiment was laid out in randomized block design with thirteen treatments and replicated thrice. The treatments include basal application of organic inputs viz. FYM (25 t ha^-1), Vermicompost (5 t ha^-1), Ganajeevamrutha (200 kg ha^‑1), Humic acid (25 kg ha^-1), Ganajeevamrutha (200 kg ha^‑1) + Jeevamrutha (500 l ha^-1) along with standard check (recommended dose of NPK fertilizers with micronutrient spray). Foliar spray of Panchagavya (3%) and banana pseudostem sap (2%) at 45, 60 and 75 days after transplanting was done in all the treatments as separate sets. Growth and yield parameters were observed in randomly selected 5 plants from each treatment plot. Application of recommended dose of NPK fertilizers + Panchagavya @ 3% foliar spary (T₁₁) recorded highest plant height (34.33 cm, 55.33 cm, 61.00 cm), number of branches plant^-1 (6.53, 9.50, 11.00) on 30, 60, 90 DAT respectively. Number of flowers plant^-1 (59.33, 80.00, 76.33) on 60, 75 and 90 DAT. Fruit length (8.41cm), fruit weight (3.82 g), number of fruit plant^-1 (158.8) and yield plant^‑1 (511.3 g) than all other approaches. Followed by organic treatment viz. application of FYM @ 25 t ha^-1 + Panchagavya @ 3% FS (T₁) recorded highest plant height (27.67 cm, 46.67 cm, 51.50 cm), number of branches plant^-1 (5.53, 7.10, 8.97) on 30, 60, 90 DAT respectively. Number of flowers plant^-1 (49.00, 71.27, 65.60) on 60, 75 and 90 DAT. Fruit length (7.66 cm), fruit weight (3.50 g), number of fruit plant^-1 (133.0) and yield plant^‑1(419.9 g plant^-1) than control (T₁₃). Hence these organic strategies can be adopted in organic chilli cultivation.
