Fertilizer recommendations for optimal soybean production in North and Center Benin

چکیده
In the traditional cropping systems of Benin Republic, soybean is mostly cultivated with no mineral fertilizer supply, despite decrease soil fertility. Furthermore, there specific available for crop, in spite its cash crop character. This leads to weak yield farmers’ fields. The present study aims determine optimal doses each N, P, K, Mg and Zn nutrient improve production Sudano-Guinean Sudanian zones Republic. Two years (2018 2019) experiment has been carried out Ouessè district (Sudano-Guinean zone) Bembèrèkè (Sudanian zone). Box Behnken rotating design was used define dose combinations leading 46 combinations. A completely randomized block set up considering farmers as replication. total four fields are selected. one-way analysis variance made on data, using linear mixed-effect model. Response surface analyses Zn. supply macronutrients combined Zn, significantly (p = 0.001) improved grain above biomass yields well harvest index. quadratic models were efficient (R² > 0.7) estimate variation. 15.46, 23.20, 28.6, 16.8 6.9 kg.ha-1, respectively (for 14.02, 23.89, 17.82, 11.45 4.26 lead an seed 2 t.ha-1 (that is, almost 2.2 times field). development formulas these determined would constitute a suitable technology helping increase both areas. Key words: Soil fertility, biofortication, design, model, leguminous, response surface, micronutrient.

How Fertilizer Recommendations Are Made
Recommendation, as we use the word here, means advice from a soil or crop specialist to those deciding how much of, what form of, and when to apply a fertilizer to a soil to benefit growth of a plant or crop. Recommendations of fertilizers and soil amendments must consider the interactions of all the factors discussed in this manual, including the soil, the crop, the climate, the beneficial eff...
متن کاملTillage and Fertilizer Placement for the Corn-soybean Rotation
The information presented is part of ongoing research to identify effective conservation tillage systems and phosphorus (P) and potassium (K) fertilizer placements for corn and soybeans. The rate of adoption of the no-till system by Iowa producers has decreased after a marked increase during the late 80s and early 90s. Actually, the area of no-till corn has decreased slightly since 1994. Severa...
