Combined effect of nitrogen and NAA on the yield of Sesame (Sesamum indicum L.)
Journal Title: Scientia Agriculturae - Year 2016, Vol 13, Issue 1
Abstract
The experiment was undertaken in the Farm of Sher-e-Bangla Agricultural University, Dhaka, during Kharif 1 season, April to July 2013 to examine the response of different levels of nitrogen and foliar application of 1-napthaleneacitic acid (NAA) on morphology, yield contributing attributes and seed yield of sesame (Sesamumindicum L.) variety BARI Til 4. The experiment was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. The total treatment combinations were 12 (3x4). Results of the experiment showed a significant variation among the treatments in respect of the majority of the observed parameters. The N significantly increased yield contributing characters- number of pod plant-1, pod diameter, pod length, seed weight plant-1, seed weight plot-1,thousand seed weight compared to control. The maximum seed yield (1.26 t/ha) was obtained from 60 kg N/ha and suggesting that N can contribute to promote vegetative growth and yield of sesame. The seed weight per plant and seed yield (1.22 t/ha) significantly increased with 50 ppm NAA. These results indicate that NAA has positive effect on reproductive attributes of sesame. The interaction between different levels of N and NAA was significantly influenced on almost yield contributing characters and seed yield of sesame. Separately, The maximum value of yield contributing characters, seed yield of sesame was observed with the combined dose of N1A2 (60 kg N/ha along with 50 ppm NAA) whereas the lowest values were obtained from control, N0A0 (0 kg N/ha and 0 ppm NAA) treatment combination. The maximum seed yield (1.49 t/ha) was obtained from 60 kg N/ha with 50 ppm NAA treatment combination. Based on the present results, it can be suggested that the combined use of 60 kg N/ha with 50 ppm NAA have increased seed yield of sesame.
