Sumario:Swine production under the deep-litter system generates high volumes of waste. The management of this waste through composting allows recycling it after an environmentally appropriate treatment. An alternative for subsequent use is the application of swine deep-litter compost (SDC) to soils used for horticultural production, which are generally degraded. The objective of this work was to evaluate the effect of different doses of SDC on productive and quality parameters of field-grown lettuce (Lactuca sativa L.). The study was carried out at the College of Agricultural Sciences, UNR, using SDC produced in the Swine Production Module of the College experimental field. The SDC doses evaluated were: 0 (T0), 6 (T1), 9 (T2) and 12 kg.m-2 (T3) in three cultivation cycles: C1 (transplant on 31st May 2017), C2 (transplant on 23rd Oct 2017), and C3 (transplant on 19th March 2018). The variables were: yield expressed as fresh weight (YFW) and dry weight (YDW), number of leaves per plant (NL), leaf area (LA), color index (CI*) and above- and belowground dry matter (DM). Data were analyzed by ANAVA. In general, the application of SDC to the soil increased YFW, NL, LA and YDW of the lettuce crop, decreasing the CI* and the DM percentage in the first two cycles. The use of SDC in horticultural systems is a viable alternative, which allows taking advantage of the waste generated by swine deep-litter production system, thus reducing environmental risks.
