Use of Low Cost Hydroponics Technique for Growing Coriander at Laboratory Conditions

Abstract

The experiment on low cost hydroponics for growing coriander at laboratory conditions for increasing production per unit area economically. Low cost hydroponics system is the new scientific techniques of growing plants passively without providing mechanical circulations and artificial aerations around the zone of roots. The type of passive technique followed here is modified Kartky system. To illustrate, the experiment was laid down in Completely Randomized Design with five different types of hydroponic nutrient 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 coco peat was filled along with seeds on each hydroponics cup. Accordingly, the major observations were taken on 10, 20 & 30 Days after sowing on the basis of specific parameters such as: number of leaves, length of leaves, number of rootlets, length of rootlets, total length of the seedlings and chlorophyll content. To summarize in the end, it was concluded that T2 (NPK- 15:15:15+ 0.5% calcium nitrate + 0.5 % magnesium sulfate) reported to be the best nutrient treatment solutions with higher germination rate, good root architecture, higher chlorophyll content and other parameters.
