• Abstract

  Intercropping Arabica coffee (Coffea arabica L.) with trees species that generate an economic return, such as macadamia (Macadamia integrifolia Maiden & Betche), has been suggested as an alternative for diversifying and maximizing income. However, there is no information on how macadamia cultivars affect the performance of coffee plants, system mechanization, and profitability. An 8-yr ex…

• Abstract

  There has been increasing interest in management practices that aim the sustainability in coffee plantation, among them the use of organic fertilizers, the intercrop cultivation of cover crops, and the use of phosphogypsum to deepen the root system. However, there is still little information on the interaction of these practices. Thus, the objective of this study is to evaluate the effect…

• Abstract

  Among the nutrients required by common bean (Phaseolus vulgaris L.), nitrogen (N) is the most taken up. Nitrogen fertilizers, a major source of N for crop, have high economic and energetic costs, low efficiency of use by plants and environmental risk. Thus, there is a great interest in strategies that aimed at reducing the use of fertilizers and consequently improvements in sustainability…

• Abstract

  Several carioca-grain cultivars of common bean with early cycle and determinated growth were recently released. For this type of cultivar can express its productive potential, among other factors, it is necessary to adapting management of nitrogen (N) fertilization. The objective of this work is to study the N uptake rate and the topdressing N management in early cycle common bean cultiv…

• Abstract

  Nitrogen (N) is required in large quantities by the potato crop and the potato response to N fertilization is dependent on several factors. The application of insufficient or too high rates of N can reduce the yield and quality of produced tubers and represent losses to farmers and risks to the environment, which makes the N management complicated. The combined use of in-season measuremen…
