EVALUATION OF THREE NUTRIENT COMPOSITIONS FOR LETTUCECULTIVERS IN TWO HYDROPONIC SYSTEMSP.P. Jagtap, S. R. Bhakar, S.S. Lakhawat , P.K. Singh and M. KothariAbstract A greenhouse field experiment was conducted at Plasticulture Farm in MPUAT, Udaipur Rajasthan in 2021to examine the effects of different EC levels on the growth and weight of two lettuce cultivars grown in twohydroponic systems. Two lettuce cultivars, Ice Berg (V1) and Green Rapid (V2), were subjected to threelevels of EC i.e. 0.75 dS/m, 1.0 dS/m and 1.25 dS/m and two hydroponic systems (DWC and NFT). TheGreen Rapid cultivar with 1.0 dS/m and NFT treatment combination proved significantly more productivethan the other cultivar/treatment combinations. Based on the results, for all parameters, i.e. plant height,number of leaves, fresh weight, plant spread and dry matter were found more effective in Green rapid with1.0 dS/m EC and NFT treatment combination. It is expected that the development of a good and easy-tousehydroponic system will help growers produce high-quality vegetables including lettuce. |
