EFFECT OF NUTRIENT SOLUTION CONCENTRATIONS ON CUCUMBER TRANSPLANTS VEGETATIVE GROWTH AND EARLY YIELD

Growing conditions during cucumber transplant production can significantly affect plant growth. The aim of this study was to determine the effects of different concentrations of nutrient solution (NS) on vegetative growth of cucumber transplants and early yield. Cucumber transplants (cv. Dinero) were grown in rockwool cubes, fertigated with a NS containing (mg L-1): N 235 ; P 40 ; K 295 ; Mg 35 ; Ca 165 ; Fe 1 ; Mn 0.85 ; Zn 0.72 ; Mo 0.12 ; Cu 0, 09 and B 1.55 (electrical conductivity: EC 2 dSm-1). The NS was applied at three EC levels (EC 1, 2, or 3 dSm-1) during the first three weeks of transplant growing. EC of 2 or 3 dSm-1 was achieved by concentrating NS and increasing the EC values for1 dSm-1 daily, during 2 or 3 day. After transplanting in rockwool slabs, plants were grown in the NS of the same composition and EC at 2.2 dSm-1. The transplants were higher at EC 2 dSm-1 (23.9 cm) and 3 dSm-1(24.7 cm) than at 1 dS.m-1 (21.4 cm). This trend was kept following three weeks after transplanting. Transplants grown at EC 2 dS m-1 and 3 dSm-1 had higher number of leaves than transplants treated with EC 1 dS.m-1. The transplants grown at EC 3 dSm-1 had 32% higher dry weight than transplants treated with EC 1 dSm-1. Leaf area and specific leaf area were not affected by NS concentration. The leaf chlorophyll A and carotenoids content was increased with EC increasing from 1 to 2 dSm-1. Regarding early yield, plants treated with EC 3 dSm-1 had a 21% increase yield compared to plants treated with EC 1 dSm-1 at the transplants stage. Overall, the vegetative growth and early yield of cucumber transplants was enhanced when plants were grown with an EC of 3 dSm-1.
