Effect of tank silt, organic and inorganic fertilizers on growth, nutrients uptake yield and yield attributes of chilli (Capsicum annum L.) under Inceptisol

The experiment was laid out in a randomized block design with three replications and ten treatments. T1- Absolute control, T2- 100% RDF, T3- 125% RDF, T4 -150% RDF, T5- 100% RDF +20 kg ha-1 FeSO4, T6- 100% RDF + 20 kg ha-1 ZnSO4, T7 – 100% RDF + FYM @ 5 t ha-1, T8- 75% RDF + Vermicompost @ 2.5 t ha-1, T9- 100% RDF + Neemcake @ 2.5 t ha-1 and T10 – 100% RDF + Tank silt @ 5 t ha-1 +FYM @ 2.5 t ha-1. The Jwala variety of chilli was used for study. The effect of organic manures in combination with inorganic fertilizer was noticed on important growth parameters viz., plant height, number of branches, at different growth stages 40, 60 and 80 DAT of chilli crop. The application of 100% RDF+ Tank silt @ 5 t ha-1 + FYM @ 2.5 t ha-1 (T10) recorded highest plant height at 40 DAT (26.77cm), 60 DAT (41.52cm) and 80 DAT (72.37cm). Similarly, maximum result regarding to the number of branches at 40 DAT (6.63), 60 DAT (18.50) and 80 DAT (21.25cm) increased positively up to 80 days and which was significantly superior over rest of the treatment. The increase in yield and nutrients uptake with application of organic manure in combination with inorganic fertilizers. The maximum yield of chilli at treatment receiving 100% RDF +Tank silt @ 5t ha-1 + FYM @ 2.5 t ha-1 and recorded higher values of all the nutrient uptake N (95.26 kg ha-1), P (36.28 kg ha-1) and K (181.34 kg ha-1) and micronutrients recorded highest Fe (704.64 g ha-1) at 100% RDF +20 kg FeSO4 ha-1 (T5) and Zn (1387.18 g ha-1) at 100% RDF + 20 kg ha-1 + ZnSO4 (T6) as compared with organic or inorganic fertilizer alone.
