 भारत के आलू उगाने वाले क्षेत्रों में पी उपलब्धता के आधार पर फॉस्फोरस उर्वरकों की सिफारिश Phosphorus is one of the key nutrients required for higher and sustained productivity of potato and its influence on tuber yield is very well established. Maximum potato yield occurs when sufficient P is available during early vegetative development and the entire period of tuber growth. Total plant P uptake increases rapidly during tuber initiation, levels off to a constant rate during tuber bulking, and ceases with plant maturation occurs primarily through the transfer of P reserves from the vine and roots. Phosphorus uptake by potatoes is relatively low compared with uptake of potassium or nitrogen but similar to...

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.
