Mineral nutrient studies in papaya Carica papaya L cv Red Lady under alluvial soil of Bihar

Abstract

An experiment entitled Mineral nutrient studies in papaya (Carica papaya L) cv. Red Lady under alluvial soil of Bihar was conducted during 2016-18 at the experimental site of Department of Horticulture (Fruit and Fruit Technology), BAC, Sabour to the main objective of the study was to verified effect of different source of fertilizers and its various doses on the quantitative and qualitative characteristics along with mineral nutrient uptake pattern during different growth stages of papaya. Treatments comprising three levels each of neem coated urea (0, 100 and 200 g/plant), calcium nitrate (0, 100 and 200 g/plant) and murate of potash (0, 200 and 400 g/plant) alone and its combination were taken under Randomised Block Design (factorial) with two replication. In each replication four plants has been considered as an experimental unit. In another experiment, three harvesting time (7 A.M, 12 P.M and 5 P.M) under RBD were also chosen to evaluate the effect of harvesting time on postharvest shelf life of papaya fruits. newline
