Silicon Nutrition Effects on Growth, Yield and Metal Accumulation in Radish (Raphanus sativus L.) Grown with Municipal Wastewater

Radish (raphanus sativus L) is a vegetable very rich in vitamin C and fiber, this plant belonging to the family Brassicacae characterized by their great capacity to accumulate heavy metals such as Chromium. The aim of our work is the study of the effect of Chromium VI on the morpho-physiological parameters of radish and the assessment of health risk related to the bioaccumulation of Cr in the edible parts. The plantation of radish was made on a soil artificially contaminated by 4 concentrations of Cr(VI) (10, 20, 40 and 60ppm). After comparing the results obtained with the results of non-contaminated soil, it is observed that the Cr affects negatively the growth, yield and the content of chlorophyll, On the other hand, it is noticed that there is a slight increase of sugars, proteins and Proline content with the increase of CrVI concentration in the soil, we can explain this increase by the development of defense mechanisms by the radish plant against the stress caused by CrVI. Regarding the bioaccumulation of Cr we found that the concentration of Cr in different parts of radish is too high compared to the recommended daily dose (120µg), so it is not recommended to consume radish grown in areas contaminated by Cr.

This experiment was carried out in a shade net house at the horticultural research farm of Agriculture and Forestry University, Chitwan, Nepal during spring 2018 to identify the suitable radish (Raphanus sativus L.) variety having high yield potential with better quality roots for off season. The experiment was laid out in Randomized Complete Block Design (RCBD) with eight treatments, i.e. five improved (Vedetar Local, Miyasinge, Tokinasi, Pusa Chetki and All Season) and three hybrid varieties (Mino Early Long White F1, Ivory White F1 and MAHY 22 F1) of radish with four replications. Radish seeds were seeded in the third week of February. Miyasinge variety showed the highest plant height (43.91 cm), biomass yield (73.22 t ha-1) and fresh shoot weight per plant (127.15 g) whereas the highest number of leaves per plant (20.54) was recorded in MAHY 22 F1. Ivory White F1 variety showed the highest root length (19.51 cm), root circumference (9.31 cm), root to shoot ratio per plant (1.29) and fresh root yield (30.87 t ha-1). The highest root skin thickness (0.27 cm) was found in Miyasinge, the highest TSS (6.20 ºBrix) was observed in Mino Early Long White F1. Ivory White F1 showed the highest ascorbic acid content (19.51 mg 100 g-1), dry matter of root (7.62 %) and score (8.36) from the consumers’ acceptability test for pungency. Ivory White F1 showed superior growth, yield and quality attributes under shed net conditions.
