Agronomic application effects of organic wastes on a squash crop production

Purpose The objective of the study was to evaluate the application effects of different doses of onion residue mixed with bovine manure compost as an organic fertilizer on a hybrid Tetsukabuto squash crop cultivated in a field. Method The experimental design required randomly dividing blocks with three replicates. The experiments were designed with different dose combinations in experimental units (4 m wide x 8 m long deep). There were three treatments: organic fertilization (two compost doses 6 and 8 kg m-2); mineral fertilization (45 kg N ha-1 urea), unfertilized control. The number of leaves, main guide length per plant and dry matter were determined. Results The results obtained during the first 15-day sampling showed significant differences (p
