A field
experiment was conducted during cropping season of 2012-2013 in Angónia
District, central Mozambique, to evaluate the response of soybean [Glycine
max (L.) Merrill] to rates of Phosphorus fertilizers. The study was laid
out as randomized complete block design with four replications. The
treatments consisted of P rates of 0, 20, 40 and 60 kg P2O5 ha-1 as
Single super phosphate (SSP), with 16% P2O5 content. The results showed
that the plant height, the height to the 1st pod, number of pods,
biomass yield, weight of 100 seeds, grain yield, number of nodules and
weight of nodules were significantly affected by the treatments. The
highest plant height was observed at rate of 60kg P2O5 ha-1 (76.40 cm;
p=0.0015). The highest height to the insertion of 1st pod was observed
with application of 20kg P2O5 ha-1 (19.35 cm; p=0.0323). The treatment
of 40 kg P2O5 ha-1 presented significantly higher number of pods per
plant (44.68 pods plant-1; p=0.0101). The highest weight of 100 seeds
was observed with 60 kg P2O5 ha-1 (13.71 grams; p=0.0318). The highest
biomass and grain yields were observed with the rate of 60 kg ha-1 P2O5
(8.92 t ha-1; p=0.0078; and4.29 t ha-1; p=0.0089, respectively). The
highest number of nodules (41.35 nodules; p<0.0001) and the highest
nodule weight (521.70 grams nodules; p=0.0003) were observed with the
rate of 60 kg ha-1 P2O5. Thus, it should be recommended for soybean
fertilization in Ferralsols under Angónia’s agro-ecological conditions. How to cite this article: Matusso JMM, Cabo FGD (2015). Response of Soybean [Glycine max (L.) Merrill] to Phosphorus Fertilizer Rates in Ferralsols. Acad. Res. J. Agri. Sci. Res. 3(10): 281-288.
