Effect of integrated nutrient management on leaf nutrient status, yield and quality of spinach (Beta vulgaris L.) var. Pusa Jyoti

The present investigation entitled “Effect of integrated nutrient management on leaf nutrient status, yield and quality of spinach (Beta vulgaris L.) var. Pusa Jyoti” was carried out during kharif 2016 – 17 (first year), 2017 – 18 (second year) and pooled at the Experimental field, Krishi Vigyan Kendra, RVSKVV, Datia (M.P.) with 16 treatment combinations of three levels of inorganic fertilizers i.e. 50% RDF (75:40:50 kg NPK ha-1), 75% RDF (112.5:60:75 kg NPK ha-1) and 100% RDF control (150:80:100 kg NPK ha-1), three organic manure i.e. 20 t FYM ha-1, 10 t vermicompost (VC) ha-1 and 7.5 t poultry manure (PM) ha-1 and two bio-fertilizers viz,. 5 kg Azotobacter (Azo) ha-1 and 5 kg PSB ha-1. Experiments were laid out in Randomized Complete Block Design with three replications. Results revealed that the application of 75% RDF + 10 t Vermicompost ha-1 + 5 kg PSB ha-1 + 5 kg Azotobacter ha-1 (T8) was recorded significantly maximum leaf nitrogen (51.30, 52.30 and 51.80 g kg-1), phosphorus (7.30, 8.30 and 7.80 g kg-1), potash (57.30, 58.30 and 57.80 g kg-1), vitamin ‘C’ (49.6, 51.0 and 50.30 mg 100 g-1), chlorophyll index (140.20, 141.20 and 140.70 mg 100 g-1) and leaves yield hectare-1 (252.27, 254.87 and 253.57 q ha-1) at first year, second year and pooled, respectively as compared to control.
