Influence of land configuration and fertilization techniques on soybean (Glycine max (L.) Merrill.) productivity, soil moisture and fertility

The effect of five fertilizers; NPK (15-15-15), organo-chemical hormone mixed formula 1 (HO-1), Formula 2 (HO-2), Formula 3 (HO-3) and granular organic fertilizer (GOF) were investigated on maize yield and soil properties in a Randomized Complete Block Design with 4 replications. The new hybrid maize (GT 822) was sown at 75 x 25 cm² spacing. The fertilizer rate was 300 kg ha-1. Initial soil analysis showed that the soil had a lower rate of nutrients but after the second season of trial a significant (p ≤ 0.05) improvement was observed in soil properties, the highest residual NPK of 0.875 %, 0.0275 %, and 0.0267 % were recorded in HO-3 plots. Vegetative data showed that maize height, dry matter, leaf area, and leaf chlorophyll of 270.85 cm, 282.66 g, 156.02 dm², and 56.70, respectively were also highest in HO-3 fertilizer. Plant growth indices; RGR, LAI, and dry matter use efficiency of 0.132 g g-1day-1, 5.90 and 34.4 %, respectively were best in HO-3. Grain yield and crude protein of 8276.68 kg ha-1 and 8.99 % were recorded in HO-3, followed by HO-2 and NPK. Lower yields were obtained from the control and GOF. Our finding revealed that the integration of nutrient sources in a balanced ratio produced the greatest yield output, improved soil properties, and is therefore the future approach to planning an effective fertilizer strategy. Reliance on GOF as a sole fertility package for maize production may result in significant yield losses compared to the integrated approach or use of NPK fertilizer.

Sesame is an erect herbaceous annual plant with both single-stemmed and branched growth habits. Sesame seed yield is easily affected by soil moisture stress in semi-arid climate. Good vertisol management options that conserve moisture during dry spell period and drain excess moisture during wet periods is vital. Study area has limited rainfall therefore evidences on effect of land configuration ways on soil moisture and sesame yield is critical. A field investigation was conducted at Humera Agricultural Research Center (HuARC) during 2016 growing season in vertisol soil type. The experiment was laid out by randomized complete block design (RCBD) with three replication that consists of three land configuration ways or methods namely flat, ridge and furrow, and bed furrow. Sesame variety, Setit-1, was sown with 40 cm and 10 cm spacing between rows and plants respectively. The analysis revealed that land configuration methods had a significant effect on soil moisture and agronomic parameter. The highest sesame seed yield (558 kg ha-1) was recorded at ridge and furrow, while the lowest (400 kg ha-1) was found at the flat land configuration method. The ridge and furrow methods conserved best soil moisture for highest plant and seed yield performance.
