Productivity and grain size of coffee grown in different weed management systems

Intensive weed management is one of the most common practices in coffee cultivation areas. Consequently, some problems, such as soil degradation and selection herbicide resistant weed, have increased over time, but, if properly managed, weeds at planting inter-rows can offer benefits erosion control, nutrient recycling crop sustainability. The aim this study to evaluate effect different strategies on productivity grain size, i.e., quality. experiment installed onto a resprouting Coffea arabica L. site, four years after it was established. Treatments are implanted inter-row Urochloa ruziziensis, Pueraria phaseoloides, spontaneous vegetation maintained by mowing, herbicides, weeding. To measure dry matter accumulation, samples taken with 0.25 m2 square template plots mowing application. yield granulometry, fruits harvested, processed classified set 14 sieves (grouped flat or “moca” shapes). methods controlling weeding show significance relation production, production grains having higher market value standing out, when compared other treatments. accumulation above soil, treatments herbicides positively influenced early (2018), U. ruziziensis vegetation, late harvest (2019). tends be linked productivity, especially periods there shortage rain region under study; however, cannot stated that influence relationship (causality) has direct positive between mass future plantations.
