Agronomic traits, chemical composition and silage quality of elephant grass fertilized with poultry litter

The high generation of organic residues from the intensive farming of chickens has induced their use as fertilizer for forage crop production. This aimed to evaluate the effect of poultry litter application on agronomic traits and quality of silage of elephant grass. The experiment was conducted in the experimental field of Boa Vista Farm, in district of Cachoeira de Santa Cruz, Viçosa, State of Minas Gerais, in...

Evaluation of different sweet potato varieties for growth, quality and yield traits under chemical fertilizer and organic amendments in sandy ferralitic soils

Growth, quality and yield components of sweet potato ((Ipomoea batatas (L.) Lam. Var. Tib1, IRA1112 and Red tuber coat) were investigated under three fertilizer sources (inorganic-NPK (100 kg/ha), green manure (Eichhornia crassipes) or poultry manure at 12 t/ha, singly or in combination) with three replications. Application of E. crassipes and poultry manure fertilizers in combination significantly (P < 0.05)...

Selectivity of herbicides to erva mate (Ilex paraguariensis) plants

Herbicides can cause negative effects on the morphophysiological characteristics of agricultural crops when proper knowledge about their selectivity is not available. For erva-mate plantations, herbicides which are registered and recommended are scarce. In this sense, this study was carried out to evaluate the selectivity of herbicides applied in different doses to erva-mate. The experiment was installed in a greenhouse...
