Performance Studies on Storage of White Onion for Good Keeping Quality Onion Varieties under Ordinary Condition

Abstract

Onion is commercially cultivated and widely consumed as a vegetable and as spices in India. Post-harvest factors like curing, sorting, grading, packing, storage and transportation are, however, the main factors affecting the quality. The experiment conducted at Nashik and Karnal during Rabi seasons, revealed that at Nashik the lowest PLW (19.17 %) and total loss (29.69 %) were recorded in advance line-865 and 799, respectively, which was at par with advance lines-784, 810, 827, 885 and 857 in respect of PLW and advance lines-827, 865 and 857 regarding total loss. However, at Karnal the lowest PLW (32.24 %) and total loss (48.40 %) were recorded in advance line-793 and was at par with advance lines-784, 810, 827, 830, 832, 836 and 869 in respect of PLW and advance lines-562, 784, 810, 827, 830, 832 and 836 regarding total loss at five month after storage. It is concluded that the onion genotypes, which has recorded minimum total losses after five months of storage, can be utilized for developing a good keeping quality onion variety for the different agroclimatic condition.
