Evaluation of integrated application of organic and inorganic nutrient sources on growth and nutrient uptake by cucumber (Cucumis sativus L.)

The present study was carried out on cucumber cv. K-75 during kharif, 2018 and 2019. The experiment comprised of nine treatments of different nutrient sources including organic manures and inorganic fertilizers. The effects of organic manures (farmyard manure, vermicompost and jeevamrut) alone and in conjugation with inorganic fertilizers on growth, nutrient uptake of cucumber were observed. Integrated use of inorganic fertilizers and organic manure significantly influenced plant growth, yield and nutrient uptake by crop. The highest leaf area (394.3 cm²), vine length (3.1 m), fruit weight (273.5 g) and NPK uptake (143.6, 31.2 and 153.4 kg ha⁻¹, respectively) was in RDF + FYM @ 100 q ha⁻¹. Increment in NPK uptake under FYM @ 100 q ha⁻¹ + Jeevamrut @ 5% was 52.7, 53.2 and 46.7% over control. The currentstudy conclude that the better understanding of importance of integrated nutrient management could be a sustainable module in maintaining soil fertility thus enhancing nutrient uptake and enhanced soil health as evident by soil fertility status of soil after crop harvest.
