Effect of integrated nutrient management on kalmegh (Andrographis Paniculata)

Abstract

Data revealed pooled mean of plant height and No. of Branches per plant was significantly influenced by various treatments of manures and fertilizers. Significantly higher plant height was recorded at Vermicompost @ 7.5 t ha-1 followed by FYM 15 t ha-1 organic manure treatment. Similarly significantly higher numbers of branches were noticed with Vermicompost @ 7.5 t ha-1 followed by FYM 15 t ha-1 in organic manure treatment. At same time application of chemical fertilizer with 80:30:50 Kg/ha NPK (Half N with full P & K as basal and remaining half N in three equal splits at 25, 40 & 60 DAS) (T7) recoded significantly higher plant height (62.07 cm) and No. of branches (33.85). From the pooled data, it is revealed that the higher Fresh herbage and dry herbage yield and highest GMR was observed significantly highest with application of with Vermicompost @ 5 t/ha which is at par with application of with Vermicompost @ 7.5 t/ha (M5), and application of castor cake 2.5 t /ha. Herbage yield, GMR, was significantly highest with application of (T6) 80:30:50 Kg/ha NPK (Half N with full P & K as basal).
