Comparative Performance of Mint in Different Hydroponics Systems

Abstract

This study aimed to compare the performance of mint in two modified Nutrient film technique (NFT) hydroponic systems viz., Horizontal ( S1 ) and Vertical A types (S2 ) along with three nutrient combinations viz.,T1-NPK@ 40:65:40/hectare,T2-NPK @ 50:75:50/hectare,T3-NPK @ 60:85:60/hectare. The trail was laid out in Factorial Randomized Block Design (FRBD) with three replication at the Department of Vegetable Science in Tamil Nadu Agricultural University. The nutrient quantities were computed for 100 litre of water and were given through fertigation. The pH of 6.5-6.8 and EC around 2Ds/m was continuously maintained throughout the experimental period. The observations viz., plant height(cm), the number of leaves, the number of branches, shoot length (cm), root length (cm), fresh weight of leaves (g), fresh and dry weight of shoot and root (g) , total plant dry weight(g) were determined. It was inferred that (S1T1) vertical A type with nutrient combination of NPK @ 40:65:40/hectare have given maximum yield when compared to other treatments.
