Abstract
An experiment was conducted to standardize of seed enhancement techniques for healthy production of radish and sunflower microgreens during 2021-22 at AICRP on Seed (Crops), UAS, GKVK, Bengaluru. Among 16 different seed enhancement techniques selected for healthy production of radish and sunflower microgreens, hydropriming for 6 hours shown significantly higher microgreen quality parameters viz., tray emergence (90.0 and 94.8 %, respectively), speed of emergence (34.0 and 35.0, respectively), seedling height (21.6 and 26.1 cm, respectively), shoot mass (368.3 and 600.2 mg, respectively), seedling mass (412.2 and 635.2 mg, respectively) and microgreen yield (162.0 and 175.6 g/tray, respectively), followed by H2O2 (0.3 %) for 12 hours and Beejamrutha for 6 hours. Among 12 different growing media for healthy production of radish and sunflower microgreens, combination of coco peat (90 %) + vermicompost (10 %) has shown significantly higher microgreen quality parameters viz., water holding capacity (65.49 %), tray emergence (86.7 and 87.4 %,respectively) and microgreen yield (158.3 and 163.8 g/tray, respectively), followed by coco peat (90 %) + red soil (10 %) and coco peat (100 %). Hence, seed enhancement with hydropriming for 6 hours and growing in coco peat (90 %) + vermicompost (10 %) combination media could be used for commercial growing of healthy microgreens of radish and sunflower.
