Off-Season Green Onion Production Technology.

      Аннотация: An experiment was conducted to assess the effect of nitrogen on commercial onion varieties for off season green production in sandy loam soils at Shukranagar Village Development Committee (V.D.C), Chitwan, Nepal, from July to November 2008. The field experiment was laid out in two factors factorial Randomized Complete Block Design (RCBD) with five levels of nitrogen (0, 40, 80, 120 and 160 kg ha-1) and two varieties (Agrifound Dark Red and Nasik-53) with 4 replications. Green onion yield was observed the highest (42.38 t ha-1) at 120 kg N ha-1 where as it was reduced to 40 t ha-1 at 160 kg N ha-1. The combination of 120 kg N ha-1 and Agrifound Dark Red produced the highest green yield (43.8 t ha-1). The highest post harvest loss (29.13 %) was recorded in the treatment of 160 kg N ha-1 after 6 days of harvest. Benefit cost ratio of AFDR at 120 kg N ha-1 (5.14) was the highest as compared to N-53 (4.46) at same level of N. Hence, off-season green onion could be a better source of income for Nepalese farmers.
