Abstract:
An experiment during rabi season of 2016-17 to 2018-19. The experiment was laid out in a split plot design with four replication. The results revealed that significantly maximum bulb yield and stalk yield was recorded when fertilized the crop with 100% RDF (F₃) through fertigation during individual years and on pooled data basis, which was found statistically at par with F₂ (75% RDF) during individual years as well as in pooled results. Fertilizing the crop with 100% RDF through fertigation recorded significantly maximum plant height, equatorial diameter and polar diameter. On pooled data basis minimum doubles per plot was noted when crop was fertilized with 50% RDF (F₁). Fertigation at 10 days interval (T₃- 6 splits) produced significantly maximum bulb yield which was closely followed by fertigation at 8 days interval (8 splits) (T₂) and it was found statistically on same bar during 2016-17 and 2018-19. Similarly, significantly higher stalk yield, maximum no. of leaves plant^-1 and maximum polar diameter were recorded when onion was fertilized through fertigation in six equal splits at 10 days interval (T₃) during 2016-17 and 2018-19, respectively.
