कुफरी गौरव - भारत के उत्तरी-पश्चिमी मैदानी क्षेत्रों के लिए आलू की सर्वाधि‍क नाइट्रोजन दक्ष्‍ा कि‍‍‍‍स्‍म Potato is highly capital and labour intensive crop. Presently, India is the second largest potato producer in the world. For achieving higher productivity, fertilizer inputs particularly of nitrogen are increasing, which not only enhance the cost of production, but also is a major environmental concern.  Therefore, nutrient efficient varieties which produce higher yields per unit of nutrient applied or absorbed than other varieties under similar agro- ecological conditions play an important role in present day agriculture as the nutrient efficient cultivars would enable farmers to produce at a lower fertility level of the soil. Central Potato Research Institute, Shimla has developed a number of varieties for different agro-climatic conditions, these varieties vary in their response to nitrogen. It is possible to harvest these cultivars at varying rate of N application. So, yield of potato tuber of different varieties will determine not only N dose but also the extent of their nutrient use efficiency. Keeping these points in view, an experiment was conducted at Central Potato Research Station, Jalandhar, to find out nitrogen requirement of the popular and new potato varieties and to work out their agronomic use efficiency (AUE) under Indo Gangetic plains of India. An experiment was conducted for...
