Influence of organic and inorganic sources of nutrients on soil health and quality parameters of pop corn

Abstract

The field experiment was conducted at crop research farm of Division of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Wadura during kharif 2017. The experiment was laid in RCBD having twelve treatments and three replications. The treatments where T1(Control),T2 (RDF) (120:60:40 kg N, P2O5 and K2O ha-1 respectively), T3 (FYM @ 15t ha-1), T4 (Vermi-compost @ 5t ha-1),T5 (Poultry manure @ 5t ha-1), T6 (75% RDF + FYM @ 10t ha-1), T7 (75% RDF + FYM @ 10t ha-1 + Azospirillum + PSB + KSB) T8 (FYM @ 10t ha-1 + Azospirillum), T9 (FYM @ 10t ha-1 + Azospirillum + PSB), T10 (FYM @ 10t ha-1 + Azospirillum + PSB + KSB), T11 (Vermi-compost @ 5t ha-1 + Azospirillum + PSB + KSB), T12 (Poultry manure @ 5t ha-1 + Azospirillum + PSB + KSB).The results of the study showed that the treatment (T2) recorded highest quality parameters viz. popping percentage (83.5%), popping expansion volume (13.2 ml), flake size (2.7 cm), protein content (8.8%), total nitrogen, phosphorous and potassium uptake were (127.44, 36.72 and 159.33 kg ha-1), respectively but was at par with 75% RDF + FYM @ 10t ha-1 + AZO + PSB + KSB (T7) while significantly lowest quality parameters viz. popping percentage (73.1%), popping expansion volume (11.6 ml), flake size (1.8 cm), Protein content, total nitrogen, phosphorous and potassium uptake were 49.80, 12.86 and 69.118) kg ha-1, respectively were recorded for the treatment (T1).
