USE OF LOW COST HYDROPONICS TECHNIQUE FOR GROWINGCORIANDER AT LABORATORY CONDITIONS

Shreya Mondol and Ankan Das

Abstract

The experiment on low cost hydroponics for growing coriander at laboratory conditions for increasingproduction per unit area economically. Low cost hydroponics system is the new scientific techniques ofgrowing plants passively without providing mechanical circulations and artificial aerations around thezone of roots. The type of passive technique followed here is modified Kartky system. To illustrate, theexperiment was laid down in Completely Randomized Design with five different types of hydroponicnutrient solutions namely: T1 (NPK- 15:15:15 + 1% Calcium Nitrate + 1% Magnesium Sulfate), T2 (NPK –15:15:15 + 0.5% Calcium Nitrate + 0.5% Magnesium Sulfate), T3 (NPK- 20:20:20 +1% Calcium Nitrate +1%Magnesium Sulfate), T4 (NPK- 20:20:20 + 0.5% Calcium Nitrate + 0.5% Magnesium Sulfate), T5 (Water).These five independent treatments had 4 replications each. Furthermore, 30% buffered and sterilized cocopeat was filled along with seeds on each hydroponics cup. Accordingly, the major observations were takenon 10, 20 & 30 Days after sowing on the basis of specific parameters such as: number of leaves, length ofleaves, number of rootlets, length of rootlets, total length of the seedlings and chlorophyll content. Tosummarize in the end, it was concluded that T2 (NPK- 15:15:15+ 0.5% calcium nitrate + 0.5 % magnesiumsulfate) reported to be the best nutrient treatment solutions with higher germination rate, good rootarchitecture, higher chlorophyll content and other parameters.
