Abstract

A study for 2 consecutive years was carried out at SKUAST-K to produce high quality onions and havinglong storage under temperate conditions. The study revealed that application of boron in combinationwith zinc produce onions having better quality and storage. Sixteen treatments were applied in threereplications in RCBD (randomized complete block design). Conjugation of 7.500 kg Zn ha-1 +1.500 kg B ha-1 recorded maximum values of quality traits like protein content (13.21 percent), vitamin C content (14.79mg 100-1g), T.S.S (13.89 oBrix), pyruvic acid (8.52 ìmol g-1), dry matter content (15.78 percent) and significantlylower values for physiological weight loss (11.01 percent), sprouting (6.32 percent) and rotting (7.22 percent)followed by Z3B2 treatment.
