The present investigation entitled “Effect of integrated nutrient management on growth, leaf yield and economics 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 plant height, number of leaves plant-1, fresh and dry weight ofleaves plant-1 and leaves yield hectare-1at first year, second year and pooledas compared to control. The net return of Rs 1,79,592 ha-1 and cost benefit ratio 1: 3.88 was found maximum with the application of 75% RDF + 7.5 t Poultry Manure ha-1 + 5kg PSB ha-1 + 5 kg Azotobacter ha-1(T12) it also gave the leafyield 241.93 q ha-1(Rank third and at par with T8) but the significantly maximum leaf yield of 253.57 q ha-1 was obtained in the treatment T8 (75% RDF + 10 t Vermicompost ha-1 + 5 kg PSB ha-1 + 5 kg Azotobacter ha-1)it was gave net return of Rs 1,50,232 ha-1 and cost benefit ratio 1: 2.45 as compared to treatment T14 (50% RDF + 10 t VC ha-1 + 5 kg Azo. ha-1 + 5kgPSBha-1).Due to high price of vermicompost, the net returns and cost: benefit ratio of the treatments with vermicompost were relatively low in spite of high green yield and gross return when compared with that of Poultry Manure.Applicationof75% RDF + 7.5 t Poultry Manure ha-1 + 5kg PSB ha-1 + 5 kg Azotobacter ha-1 was economically viable treatment.
