Effects of Zinc Foliar Nutrition on ‘Gala’ Apple (Malus Domestica Borkh) Fruit Quality
To improve fruit color features research has focused on the use of foliar nutrition with zinc. There is a lack of know about apples. The aim of this trial was to evaluate the effects of foliar zinc treatment on the qualitative characteristics of ‘Gala’ apple. Apple trees Cv ‘Gala’ were submitted to a foliar spray application of Zn in the form of aqueous solution of 0.2% and 0.4% zinc sulfate (ZnSO4) for three times. Fruit was harvested at commercial ripening and physicochemical parameters, yield, crop load, yield effi ciency and zinc leaf content were measured. Results revealed that yield, crop load, fruit weight, cover color index and cover color percentage of the observed trees was infl u…
Advantages of quinoa-legume intercrops for the nitrogen availability and the biological regulation of weed species
Few scientific and technical knowledges exist on nitrogen fertilization modalities and weeding practices of Quinoa in France. Legumes as intercrops could provide ecosystem services for nitrogen fixation and for competition against weed species. This study aims at revealing that legumes can compet with weed species, and that N-rhizodeposition, N-transfer between plants can occurs. The study was a factorial experiment in greenhouse, in trays and rhizotrons, with Quinoa (crop, sown at 48 pl/m²), Trifolium repens (legume, sown at 97 pl/m²) and Ambrosia artemisiifolia (weed, sown at 21 pl/m²). The results showed that intercropping clover reduced the biomass of Quinoa without decreasing its yield…
