DRY MATTER ACCUMULATION OF THE GREENHOUSE CUCUMBER CROP

Horticultural cultivations growth physiology under the greenhouse intensive protected agriculture modality study is important in the generation of information on some aspects that allow to improve the agronomic handling, for example mineral nutrition regarding. For the importance of the cucumber crop in this context, it was cultivated in greenhouse at the Universidad Autonoma Chapingo (Mexico) the hybrid cucumber "Saber" with four concentrations of the Steiner's universal nutritious solution (25, 75, 125 and 175%), under the random blocks experimental design, with three repetitions, between April and August 2006. During 135 days after the transplant, every 15 days, it was quantified the dry matter of stems, leaves, trendrils, flowers fruits, whole dry matter and yield. With the nutritious solution to 175% it was obtained highest expression of crop growth through bigger accumulation of dry matter and yield of 8.20 kg by plant, that overcame in 59, 22 and 15% to the yield obtained with the concentrations of the 25, 75 and 125%, respectively, this shows the cucumber cultivation response to the differential nutrients supply handling, because with the nutrient solution to 25% lower values of yield, whole dry matter and organs accumulation were obtained.
