Comparative effect of organic manures and inorganic fertilizers on vegetative growth, yield and quality of ber (Zizyphus mauritiana) cv. Gola under semi-arid conditions

An experiment was conducted at SKN College of Agriculture, Jobner (Jaipur) Rajasthan, to find out the comparative effect of organic manures and inorganic fertilizers on growth parameters of three year-old ber (Zizyphus mauritiana Lamk.) cv. Gola during 2015–16. Four levels of organic manures (control, FYM @ 20 kg/plant, vermicompost @ 6 kg/plant and poultry manure @ 8 kg/plant) and five levels of RDF (control, 50% RDF, 75% RDF, 100% RDF and 125% RDF) were used in a randomized block design with three replications to balance fertilizer requirement under semi-arid region of northern India. The application of vermicompost @ 6 kg/plant and 125% recommended dose of fertilizers significantly influenceal growth parameters (plant height, plant spread (E-W and N-S), number of primary branches, average length of primary branches, number of secondary branches/primary branche and leaf area), fruit yield (kg/plant and q/ha) and fruit quality (TSS and acidity content.
