The objective was to develop and test a procedure for applying variable rates of fertilizers and evaluate yield response in coffee (Coffea arabica L.) with regard to the application of phosphorus and potassium. The work ...

Carrot (Daucus carota L.) is a cool-season vegetable normally classified as a biennial species, requiring vernalization to induce flowering. Nevertheless, some cultivars adapted to warmer climates require less vernalization ...

A molecular characterization of tubulin and microtubule-associated proteins (MAPs) along with their intracellular pool distributions in both unfertilized and fertilized oocytes of the trout Oncorhynchus mykiss was carried ...

This research aim to evaluate the efficiency of variable fertilizer rate in croplands under precision agriculture (PA) in Rio Grande do Sul State with different level of technologies adoption. In the first chapter was ...

Spike fertility index (SF) is a trait easily measured at maturity andstrongly associated with the number of grains per unit area. In order to identifygenomic regions involved in SF control, a biparental (Baguette 10 × Klein ...
