Evaluation of the Effect of Charcoal and Seeding Depth on the Agronomic Performance of Zucchini (Curcubita pepo) in Korhogo

In order to improve zucchini production, the combined effect of charcoal amendment and seeding depth was tested at botanical garden Peleforo Gon Coulibaly University in Korhogo. To this end, six (6 kg) activated were buried elementary plots one month before sowing assess its on soil fertility. The experimental design that completely randomized two-factor blocks which are depth. Sowing carried out after application due three seeds per hill different depths. Namely 0 inch, 1.5 inch 3 inch. These same depths repeated control compare their agronomic performance zucchini. results obtained show a campaign use biochar, chemical parameters (pH, CEC, K+, exchangeable Ca2+ Mg2+) experienced significant increases. porosity has also been reduced. Zucchini fruit yields increased by 100-250% with compared control. Therefore, can be popularized as sustainable alternative conventional fertilization yield sandy loam soils.
