Abstract
The present investigation was carried out to standardize best growing media for Indian palak. The transplanting for winter season was done in October while that for the summer season was done in March and February using Nutrient Film Technique (NFT) and UV-stabilized growth bags containing coco peat and soil media. The experiment was laid out in completely randomized design (CRD) with six treatments in which plants were raised with NFT, soilless media in growth bags and in soil with and without 5% spray of jeevamrit. The NFT system consisted of PVC channels in which nutrients were recirculated at definite intervals, but for cocopeat and soil, the nutrient and water requirements were supplied as per recommended dose. Among treatments, T2 (5 per cent spray of Jeevamrit + Plants raised in Nutrient Film Technique) had largest leaf area, NPK content in leaves, total nutrient uptake, higher dry matter of above and below ground mass as well as yield. It also showed the highest BC ratio (2.50:1) making it the most profitable and cost effective growing media for Indian palak. This hydroponic medium has the added advantage of being easily replicable in urban and peri-urban areas with little or no space for commercial agriculture.
