07 Oct Role of Leaf Colour Chart in Nitrogen Fertilizer Management in Paddy
धान फसल में नाइट्रोजन उर्वरक प्रबंधन में लीफ कलर चार्ट की भूमिका Paddy is the most staple and nutritive food crop for world human population and other animals.It requires nutrient elements for their establishment and survival. Among those nutrient elements, nitrogen (N) is the most important nutrient which is essential for photosynthesis and thereby increases the yield. Unlike other crops, N can be managed effectively at real time all the stages of crop growth by using Leaf Colour Chart (LCC). Even this technique is being in use for several years, most of the formers are not aware of this technique. But this is simple, inexpensive and easy technique to manage the N in paddy by formers without any others helps. N management in paddy: Application of N fertilizer to the crop is based on type of varieties, spacing, nitrogen requirement, number of splits of nitrogen doses, etc., Check the overflow of water or runoff immediate after the fertilizer application to check the nitrogen loss through runoff water. In the same time denitrification losses arealso be checked. Large application of nitrogen should be avoided for low nitrogen response varieties such as white Ponni. If nitrogen deficiency is observed, 25% of recommended dose nitrogen fertilizer should be applied excessively to overcome the deficiency. It means 125% of recommended dose...
