“…In the present study higher seed yield was recorded as compared to other reports in Ethiopia may be because of the reason that at kulumsa is conducive for onion seed production (cool climate) and the rainfall was uniform during bolting and flowering stage. The current result was in accordance with the findings of Hossain et al (2017) in that, the maximum seed yield per hectare (957.6 kg) was found from 114 kg N and 42 kg P ha -1 and the minimum (776.6 kg) was obtained from 57 kg N and 21 kg P ha -1 . Getachew (2014) reported the highest seed yields per plot and per hectare were obtained from plants that received 115kg P 2 O 5 and 114 kg N ha -1 .…”

“…This result was in line with Hossain et al (2017) who reported the maximum number of seeds per umbel (555.20), which was found from 114 kg N and 42 kg P ha -1 and the minimum (494.00) was from 57 kg N and 21 kg P ha -1 treatments. According to Kiros et al (2018), the highest numbers of seeds per umbel were recorded in plots which received 50, 75 and 100% of 69 kg N and 92 kg P 2 O 5 ha -1 fertilizer rates (825.3, 897 and 860 respectively) compared with unfertilized (675) plots and lower rates (714.2).…”

“…The seed yield result of the present study is in analogous with the findings of Hossain et al (2017) in that, the maximum seed yield per plant (4.21 g) was recorded from 114 kg N and 42 kg P ha -1 and 57 kg N and 21 kg P ha -1 produced the minimum seed yield per plant (3.20 g). Debashis et al (2017) indicated that, Nitrogen at 175 kg ha -1 recorded significantly highest seed yield per plant.…”

“…On the other hand, the current study results were in contrast to Tamrat (2006) and Ali et al (2007Ali et al ( , 2008 who reported that phosphorous fertilizers did not have significant effect on 1000 seed weight. The maximum weight (3.42 g) was gained from 114 kg N and 42 kg P ha -1 treatments and the minimum (3.18 g) was from 57 kg N and 21 kg P ha -1 treatments (Hossain et al, 2017).…”

Onion is an important vegetable crop commercially grown both by large and small scale farmers in Ethiopia. Its production is highly dependent on availability of high and good quality seed, which is constrained by a number of problems including declining soil fertility and inappropriate fertilizer application. A study was conducted to investigate the effects of nitrogen (N) and phosphorus (P) fertilizer rates on onion seed yield and quality. The experiment was conducted at Kulumsa, South East Ethiopia, using four levels of N (0, 50,100 and 150 kg N ha-1) and four levels of P (0, 35, 70 and 105 kg P 2 O 5 ha-1) fertilizers arranged in 4 × 4 factorial arrangements in randomized complete block design with three replications. The result of the study revealed that almost all of the yield and yield component parameters considered were significantly affected by the treatments. The crop phenology, growth and yield components were significantly influenced by the rate of N and P fertilizers and their interactions. More specifically, seed yield and seed quality were significantly (P<0.01) varied among treatment combinations. The combination of N at 100 kg N ha-1 and P at 70 kg P 2 O 5 ha-1 gave the highest seed yield (1858.82 kg ha-1) with yield increment of about 57.72% over the control (no fertilizer application). As main factors each of N and P fertilizers at rates of 100 kg N ha-1 and 105 kg P 2 O 5 ha-1 resulted in highest germination percentage of onion seed. Therefore, a combined application of N at 100 kg N ha-1 and P at 70 kg P 2 O 5 ha-1 rates can be recommended for onion seed producers in the study area and areas of similar agro-ecology.
