Evaluation of the Growth and Yield Response of White Radish (Raphanus Raphanistrum Subsp. Sativus (L.) Domin) Subjected to Different Tillage Method in Mubi, Adamawa State, Nigeria.

Abstract:

This study was mainly aimed at evaluating the growth and yield response of white radish (Raphanus sativus L.) subjected to the common tillage methods in Mubi, Nigeria. A field experiment was carried out during the planting season of 2021 and 2022 in the research farm of Adamawa State University, Mubi. The experimental treatments consisted of Zero tillage (ZT), Ploughed, Harrowed and Ridged (P+H+R) and Ploughed plus Harrowed (P+H). The seed of the radish plant was planted at an inter and intra-row spacing of 20 and 30 cm respectively. The study revealed that, the three tillage methods had significant difference in their effect against the growth characteristics of the radish plant with the ZT having the significantly highest plant height, leaf fresh weight and shoot dry weight. The lowest values for most of the white radish growth characteristics were due to the P+H+R treatment. Again, it was indicated that, the different tillage methods had significant effect on the yield characteristics of the radish plant. The P+H+R treatment resulted to the significantly highest root length (20.93 cm), root diameter (6.40 cm) and root yield (200.82 kg/ha) than ZT and P+H treatments. Similarly, ZT and P+H treatment resulted to the significantly highest root weight (69.39 g) and root biomass (8.23 g) respectively than other tillage treatment. However, the P+H resulted to the significantly lowest root yield (29.95 kg/ha) of the radish plant. It was concluded that, for better root yield response of white radish plant in Mubi, farmers should adopt P+H+R tillage method.
