Determination of the plant quality in cortadillo (Nolina cespitifera Trel.) Under chemical and biological fertilization in nursery
Abstract: Plant quality is the ability of plants to adapt and develop under climatic and edaphic conditions of plantation sites. It depends on the genetic characteristics of germplasm and techniques used for its reproduction in nursery. Nursery management practices influence directly on plant quality, which is determinated by indexes generated from morphological and physiological variables. The aim of this study was to determine the plant quality cortadillo (Nolina cespitifera Trel.) under chemical and biological fertilization. Nine treatments were designed: Three chemical fertilizers (Urea, 18-18-18, 17-17-17), four biological (Trichoderma sp., Bacillus sp., Mycorrhiza INIFAP and mixture of mineral coal and Trichoderma spp. and Bacillus spp.), covered with gravel and a control. The experimental unit was a plant. A completely randomized experimental design with 12 repetitions were used. The plant quality ranges were determined in each variable and a quality plant index was performed using the total data. The results indicate that it is possible to obtain high quality plant using a mixture of activated charcoal and microorganisms, such as Trichoderma sp. It is recommended the use of containers with large dimensions (5 x 15 cm), in order to plants had greater growth area. Also, it is prescribed to adjust the doses of chemical fertilization and / or combined with the treatments of biological fertilization, to obtain plants of N. cespitifera of higher quality, and therefore, greater survival in plantation sites.
