The experiment was conducted to study the response of summer onion to N2and Naphthalene Acetic Acid (NAA). The experiment consisted of two factors. Factor A: 4 levels of Nitrogen viz. N0-0kg (control), N1-90kg ha-1, N2-110kg ha-1and N3-130kg ha-1and Factor B: 4 levels of NAA viz. H0-0ppm, H1- 50ppm, H2-100ppm and H3-150ppm. The experiment was laid out in Randomized Complete Block Design with three replications. Results revealed that in terms of nitrogen, the highest bulb diameter (4.90cm), bulb weight plant-1(51.48g) and bulb yield ha-1(17.78t) were found from N2(110kg N ha-1). In case of application of NAA, the highest bulb length (3.22cm), bulb diameter (4.38cm), bulb weight plant-1(45.18g) and bulb yield ha-1(15.49t) were recorded from H2(100ppm NAA). Regarding combined effect of nitrogen and NAA the highest bulb length (3.76cm), highest bulb diameter (5.26cm), highest bulb weight plant-1(55.50g) and highest bulb yield ha-1(19.60t) were recorded from the treatment combination of N2H2. Considering economic analysis, the highest BCR (2.39) was also obtained from N2H2(110kg N ha-1with 100ppm NAA) treatment combination. |
