Abstract:
A field experiment was carried out during rabi season of 2015-16 on vertisols of Navsari, Gujarat to study the “Nutrient management in Indian bean (Lablab purpureus L.) Under south Gujarat condition”. The soil of experimental field was clayey in texture, low in available nitrogen (197.26 kg/ha), medium in available phosphorus (30.93 kg/ha) and fairly rich in available potassium (369.80 kg/ha). Total twelve treatment combinations consisting of two levels of inorganic fertilizer viz., F1 (100% RDF) and F2 (125% RDF), three types of organic manure viz., O1 (2 t/ha FYM), O2 (2 t/ha Biocompost) and O3 (2 t/ha Vermicompost) and two levels of foliar spray viz., S1 (Without spray) and S2 (1% Banana pseudostem enrich sap spray at 30 and 60 DAS) were evaluated in randomized block design with factorial concept with three replications. The result showed that quality parameters like protein content (20.35%) and protein yield (149.06 kg/ha) as well as N, P and K content and uptake by seed, stover and their total and availability of N, P₂O₅ and K₂O in the soil after harvest of Indian bean were also recorded significantly higher with application of 125% RDF through inorganic fertilizer (F2) over 100% RDF (F1). The treatment O2 (2 t/ha biocompost) resulted in significantly higher protein content and protein yield (20.93% and 153.15 kg/ha, respectively). Almost similar trend was also found for N, P and K₂O content and their uptake by seed and stover as well as available N, P₂O₅ and K₂O status of soil after harvest of crop. Significantly higher content and uptake of N, P and K by seed and stover and their total as well as available N, P₂O₅ and K₂O status of soil after harvest of crop were also recorded under foliar application of 1% banana pseudostem enrich sap over control.
