tailieunhanh - Productivity, storability and economics of Microsprinkler Fertigation for winter onion (Allium cepa L.) in semi-arid conditions

Onion has very shallow root system that is frequently irrigated and fertilized with high fertilizer dose rates to maximize yield. Converting from furrow-fertigated to microsprinkler fertigated onion production may reduce fertilizer needs. The influence of fertigation sources and their levels, applied through microsprinkler irrigation on winter onion (Allium cepa L.) was evaluated for the years 2009-2011 under semi-arid region of India. The experiment was laid out in factorial randomized block design with nine treatments replicated thrice under microsprinkler system comprising three fertigation sources in main plots with three fertigation levels in sub plots. |
