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

Abstract

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.

Integrated effect of nitrogen and vermicompost levels on yield and yield components of carrot (Daucus carota L.) at Woreta, Northwestern Ethiopia

“…Sylvestre et al (2015) in their study on effect of poultry manure and NPK (17-17-17) on growth and yield of carrot stated that maximum carrot harvest index was found by integrating 5 tha -1 poultry manure with 150 kg ha -1 NPK which was similar with sole application of 10t ha -1 poultry manure. The current study is also in line with the work of Yagoub et al (2012).…”

Réponse du soja (<i>Glycine max</i> L.) à des doses croissantes du DAP et Urée au Sud-Kivu, RD Congo

“…Le phosphore étant l'un des éléments nutritifs majeurs affectant le rendement du soja dont sa déficience réduit significativement son rendement, sa présence dans le DAP expliquerait le rendement plus élevé comparativement aux traitements en urée (Matusso & Cabo, 2015). En effet, plusieurs autres auteurs ont déjà mis en évidence la variation du rendement du soja due aux différentes sources des nutriments utilisées dans la fertilisation (Yagoub et al, 2012 ;Kasongo et al, 2013et Verde et al, 2013. Effet des doses d'engrais sur le rendement du soja et ses composantes : Le rendement du soja et ses composantes ont varié significativement et proportionnellement avec les doses d'engrais appliquées, la dose de 150 kg ha -1 permettait d'obtenir des rendements plus élevés quelle que soit la source d'engrais utilisée.…”

Organic fertilizers improve the growth, seed quality and yield of newly released soybean (Glycine max (L.) Merrill) varieties in the tropics

“…Enhanced growth could be attributed to provision of macro and micro nutrients required for vegetative growth by the manure. Significant growth response to applied manure and compost had been reported by Yagoub et al ( 2012) and Sutrisno (2017). On average, organic fertilizer application also significantly (P<0.05; F-test) increased pod number and weight, and weight of seeds per plant in both years, except pod weight in 2016.…”
