VAZQUEZ-CASARRUBIAS, Gabino et al. Age at transplant and its effect on growth and yield of chili apaxtleco. Rev. Chapingo Ser.Hortic [online]. 2011, vol.17, n.1, pp.61-65. ISSN 2007-4034.

Transplanting in intensive horticultural systems, such as chili, has permitted better planning of crops with preformed structures and growth uniformity, efficient use of seed, and early production. The objective of this study was to determine the effect of plantlet age at transplant on phenology, growth and yield of apaxtleco chili (Capsicum annuum L.) from Apaxtla, Guerrero, Mexico, grown in a greenhouse. Treatments were three ages at transplant: 15, 30 and 45 days after emergence (T1, T2 and T3, respectively) distributed in a randomized block design with eight replications. Plant density was 26 plants·m^-2. The results indicate that with T3 a larger number of fruits, leaf area and plant height were obtained. In biomass, plants in T1 accumulated more in the stem (57 %), followed by leaves and fruit (29 and 14 %, respectively). With T3, more biomass was accumulated in the fruit, and consequently, yield was higher (44.3 g·plant^-1) 1.15 kg·m^-2.
