Introduction Agriculture is the backbone of the Indian economy, employing nearly half of the population and contributing significantly to GDP. However, conventional farming faces persistent challenges such as land degradation, over-dependence on monsoons, dwindling groundwater resources, and climate change. Against this backdrop, hydroponic cultivation —a soilless farming technique where plants are grown in nutrient-rich water solutions—emerges as a transformative practice with the potential to revolutionize Indian agriculture and bolster the economy. Why Hydroponics is Relevant for India Efficient Use of Resources Hydroponics consumes up to 90% less water compared to traditional farming, crucial for a country like India where water scarcity is intensifying. It requires less land area, allowing cultivation even in urban and peri-urban spaces. Higher Yields and Year-Round Production Controlled environment farming ensures consistent yield...
Foliar spray is a vital technique in modern agriculture, used across a wide range of crops including vegetables, fruits, and field crops. It involves applying liquid fertilizers, micronutrients, growth regulators, or pesticides directly to the leaves of plants. This method provides rapid nutrient absorption and plays an essential role in enhancing crop yield, correcting nutrient deficiencies, and protecting against pests and diseases. 1. What Is Foliar Spray? Foliar spray is the process of spraying nutrient solutions or agrochemicals onto the foliage (leaves) of plants. Unlike soil fertilization, where nutrients are absorbed through the roots, foliar application allows nutrients to be absorbed directly through the stomata and epidermis of the leaf surface. This method is particularly effective when root uptake is hindered due to poor soil conditions, drought, or root damage. 2. Importance and Benefits Rapid Nutrient Uptake : Nutrients sprayed on leaves can ...
