“…Fertilizers increased the number of pods per plant. Similar results were reported by [22,23,26,27]. In contrast, [19,21] observed that increasing the levels of nitrogen fertilization had no effect on the mean number of pods per plant.…”

“…In contrast, [19,21] observed that increasing the levels of nitrogen fertilization had no effect on the mean number of pods per plant. The number of seeds per pod was slightly affected by nitrogen fertilization as noticed by [22,23,27]. The effect of fertilizers on the weight of seeds per plant and 100 seeds weight of soybean is presented in Table 7.…”

Effect of Urea, NPK and Compost on Growth and Yield of Soybean (Glycine max L.), in Semi-Arid Region of Sudan

2012

A field experiment was conducted for two consecutive seasons (2009/2010 and 2010/2011) on the Demonstration Farm of the College of Agricultural Studies, Sudan University of Science and Technology at Shambat, to study the effect of some fertilizers on growth and yield of soybean (Glycine max L. merril). The experiment was laid out in a randomized complete block design (RCBD) with four replicates. The fertilizers treatments consisted of three types of fertilizers: urea (180 kg/ha), NPK (361 kg/ha), compost (%) and the control. The results showed that fertilizers treatments in first season had significant difference on number of pods/plant, economic yield, harvest index. Mean while, highly significant difference on green, biological and straw yield. In second season fertilizers treatments had significant difference on plant height at 30 days, leaf area at 45 and 60 days, green yield, biological yield and straw yield.

“…This in turn, accelerated the vegetative growth, enhances the photosynthetic activity which eventually form the carbohydrate pools, yield and yield components were subsequently increased. The results are also in good agreement with those obtained by Mohamed and Ezzat (1996), Agha et al (2004), Hoda (2009 and Janssens et al (2010). It can be seen in Tables (7&8) that all herbicides significantly increased growth characteristics and yield of soybean except plant height, pods number in the first season and plant height, pods weight per plant -1 and seed weight per plant -1 in the second one.…”

“…The same trend was observed in the second season which were 41.1 and 27.0, respectively, with FYM and 36.4 and 13.6 %, respectively, with NPK fertilizers. Similar results were obtained by Soliman et al (1995), Mohamed and Ezzat (1996), Zayed (2003) and Agha et al (2004).…”

“…Barabasz et al (2002) showed that mineral fertilization of arable land increased the biological productivity of various ecosystems as well as the microbial activity in the soil. Agha et al (2004) stated that 50 kg N/ha + inoculation of Rizobia japonicum increased nodule numbers, number of pods per plant, number of seeds per pod, seed weight per plant, seed index, number of nodules per plant and seed yield. Lv et al (2005) indicated that in addition to providing necessary nutrients for crops and improving soil physico-chemical properties, organic fertilizer is able to enhance soil microbial activity of soil, such as improving the activity of soil enzymes and increasing soil microbial biomass.…”

The present work was conducted to investigate the effect of fertilizers {mineral fertilizers (NPK) and organic fertilizer (FYM) and some herbicides (Pendimethalin at the rate of 1.7 l/fed, Prometryn at the rate of 1.0 l/ fed, Metolachlor at the rate of 1.0 l/ fed, Metribuzin at the rate of 300 g/ fed and untreated) on weeds, bacterial nodulation and soil microorganisms associated soybean crop during 2012 and 2013 summer seasons.The results showed that FYM fertilizer significantly increased the dry weight of grassy and broadleaved weeds (g/ m 2 ) after 30 days from sowing. Also, it increased the number and dry weight of nodules/plant, the number of soil microorganisms, pod number /plant, pod weight /plant (g), seeds weight / plant (g), seed yield (ton/ fed.) and NPK seed contents % compared to no fertilizer. This was true in both seasons. All the studied herbicides significantly decreased the dry weight of grassy, broad-leaved weeds and decreased number and dry weight of nodules / plant, number of soil microorganisms and increased pods number /plant, pods weight /plant (g), seeds weight /plant (g), seed yield (ton/fed.) and NPK seed contents % compared to untreated treatment.It can be concluded from this study that application of Pendimethalin at the rate of 1.7 l/ fed and Metribuzin at the rate of 300 g/ fed. with FYM fertilizer were the best for weed control and gave the highest soybean yield.
