16 Nov Recommendation of phosphorus fertilizers based on P availability in potato growing regions of India
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...
