ONION YIELD, QUALITY AND STORABILITY AS AFFECTED WITH DIFFERENT SOIL MOISTURE AND NITROGEN REGIMES

摘要: Onion (Allium cepa L.) is one of the most important vegetable crops grown in world. It valued for its distinctive pungent flavor and an essential ingredient cuisine many regions Hence, present studies were undertaken with objective to evaluate differential water nitrogen regimes quality onion production better shelf life. Studies conducted observe effect different soil moisture micro- sprinkler irrigation system under temperate climate condition 2 years (2009-2010). Soil regime levels consisted four treatments based on cumulative pan evaporation replenishment (0.50, 0.80, 1.10 1. 40 PE). Similarly three (50,100 150 kg/ha).Irrigation had marked yield onion. Irrigation at 1.40 PE kg/ha produced higher bulbs dry matter yield. Mean bulb size weight, which decreased decrease amount nitrogen. The percentage marketable bulbs, considered commercially important, been considerably 100 Total soluble solids increased up 0.80 then declined slightly, where as it varied A decreasing trend protein content was recorded increase from 0.50 PE, however resulted minimum physiological loss weight (%) during 60 days storage. But extended storage
