Adherents evaluation for seeds coating (Zea mays L.) with vegetable meal from stubble and their effect on germination

Abstract

Objective: To evaluate the adhesion capacity of different materials in   seeds coating with vegetable meal from broccoli stubble as biostimulant extracts.

Design/methodology/approach: The percentage of seed coverage was evaluated for seeds treated with different binders: commercial, polyterpene, carboxymethyl, starch, and casein, previously standardized for application in doses of 1 ml per 100 seeds. Treatments with binder with and without vegetable meal, with 1.5 g applied to 100 seeds, were evaluated for seedling germination percentage, as well as growth and biochemical variables.

Results: The adherents with the highest coverage were commercial and polyterpene, with coverage percentages greater than 98%. Germination was not modified by the treatments, unlike the application of HV which reduced plumule length by 7% and fresh weight by 12%. There were no statistical differences in the other variables concerning treatments without HV. Regarding the effect of adherents, similar results are presented for most variables, where there are no statistical differences between adherents. In biochemical variables, the application of adherent and vegetable flours favored the content of phenols, total proteins and pigments.

Findings/conclusions: The information from this study can serve as a model for applying plant flours as biostimulant extracts to seeds or plants, with a sustainable approach
