The use of organic compost in agriculture is a practice that brings many advantages, avoiding environmental contamination and nutrients immobilization, besides being a source of
organic matter in soil. Thus, this study addresses the production of organic compost through the association of wastes in different intervals of tilling. These practices are undertaken to better understand the influence that these procedures, association of waste and different tilling intervals, have on the final product and its influence on the cultivation of sorghum (Sorghum bicolor). The experiments were conducted on the Universidade Federal de Lavras? campus, one in field and another in greenhouse. Two different mixtures of residues for compost were made, only coffee husk and coffee husk associated with cattle manure, wich suffered four different tillage intervals and after obtained the compost they were tested in agricultural crop. Larger tilling intervals reduce nitrogen loss and decrease the need of labor. Organic composts obtained with shorter tilling intervals present a lower electrolytic conductivity. The addition of manure to the coffee husk provides a decrease in the C / N ratio. Composts from the mix of coffee husk and manure provide better results for fresh and
dry biomass. |

In desalination process, besides the potable water, highly salty and pollutant water (brine) is generated, which can be used for producing crops since it is carefully monitored. In order to test this hypothesis, bell pepper plants, cv. 'Margarita', were grown in coconut fiber substrate under greenhouse and were irrigated with nutrient solutions prepared with tap water, brine from desalination plant, and its dilution with tap water at 75, 50 and 25%, giving a range of electrical conductivities of the nutrient solution (ECs) of 2.6, 3.1, 6.6, 10.0 and 12.2 dS m-1 after the dilutions and fertilizers addition. Completely randomized blocks design was used with 5 treatments (salinity levels of the nutrient solutions) and six replications. Leaf area, number of marketable fruit, total and marketable yield were reduced with ECs increase. The marketable yield of bell pepper 'Margarita' reduced 6.3% for each unitary increase of ECs above 2.6 dS m-1 (threshold salinity) and the results suggest that in hydroponic system, the reduction of marketable yield with increasing ECs is promoted by reduction of the number of fruits per plant instead of a reduction of fruit mean weight. |
