| Abstract:
This work was done in the company “Vegetales de Oaxaca SPR de RL” Trinidad Zaachila, Oaxaca (South Mexico) during spring-summer 2011. We have evaluated nine growing media, volume mixes of different local materials composted: pine bark + peat (70:30); maguey bagasse + peat (70:30), Morelos coconut fiber + peat (70:30), pine bark + maguey bagasse (50:50), coconut fiber Rio Grande (100%) Morelos coconut fiber (100%), peanut hulls (100%) and maguey bagasse (100%). All these mixtures had been used during a previous crop cycle. Pine sawdust that had not been used before, served as control substrate. Bagasse mixtures maguey + peat (70:30), pine bark + peat (70:30), coconut fiber Rio Grande (100%) Morelos coconut fiber (100%) and maguey bagasse + bark pine (50:50 v: v), showed better yields 6.592 kg.plant-1, 5.950 kg.plant-1, 5.602 kg.plant-1, 5.271 kg.plant-1 and 5.154 kg plant-1, respectively. The height and width variables showed no significant differences. The treatment showing best performance, best height, fresh weight of leaves, stems and roots was agave bagasse + peat (70:30). | |
