Effect of planting density on the growth of radish (Raphanus sativus L.) plants under greenhouse conditions

Abstract:

The plant growth analysis has been developed over the decades as a discipline related to the ecophysiology and agronomy, with their own concepts, terms and calculation tools. In the Bogota Plateau and under greenhouse conditions this study was carried out in order to analyze the effect of different densities (1, 2, 3 or 4 plants per 201 cm2 pot) of sowing on growth and yield of plants of radish. The measurements were carried out starting from 12 days alter planting and every four days in order to analyze the dynamics in growth of leaf area, diameter of roots, fresh weight of roots, leaf area index, net assimilation rate, crop growth rate, relative growth rate, and yield/area. The planting densities affected rate dynamics of growth of radish plants, increasing to 24 days after transplanting, at which time its speed was reduced, indicating the onset of maturity. In addition, low densities increased the leaf area and yield per plant but reduced the yield/area. The highest production (28 g/pot) was achieved with the highest densities (3 and 4 plants/pot).Additional key words: growth analysis, leaf area, yield.
