In this sense, the present work aimed to evaluate the effects of soil protection against water loss and the use of bovine biofertilizer on fruit production and chlorophyll content in bell pepper plants. Greater water-use efficiency (WUE) can be obtained with the use of crop management techniques that minimize the water loss by evapotranspiration and by lateral movement, which reduce the water content of the root environment of plants. Biofertilizer production The chemically enriched biofertilizer was obtained by anaerobic fermentation of a mixture of equal volumes of fresh manure and water (not saline or chlorinated), 1% MB-4 rock powder (17.82% of Mg2+), 1% ash (13.61 cmolc dm-3 of K+), 1% brown sugar and 1% milk in a polyethylene biodigester with a capacity of 240 L. This container was kept in the shade and hermetically sealed for 30 days. Irrigation was provided daily by the drip-irrigation method using drip tape with drippers spaced 20 CM apart at a flow rate of 4.75 L h-1, which was based on the evaporation of water in a class "A" tank installed at the location of the experiment.
