Effect of Different Types of Lights on Growth, Yield and Quality of Kale (Brassica oleracea var. Acephala)

A research project was conducted to investigate the impact of different types of lighting on the growth, yield, and quality of Kale (Brassica oleracea var Acephala), under the Prayagraj Agro Climatic conditions. The experiment comprised of treatments T0 (Outdoor under sunlight), T1 (LED bulb white), T2 (LED tube white), T3 (General bulb), T4 (LED bulb full spectrum), T5 (LED white bulb + LED bulb full spectrum), T6 (LED tube white + LED bulb full spectrum), T7 (General bulb + LED bulb full spectrum), T8 (LED bulb full spectrum). To the study's findings, among the various treatment levels, treatment T2(LED tube white) showed the highest values in growth parameters such as plant height (30.01 cm), petiole length (15.07 cm), and number of leaves per plant (14.33 leaves). It also demonstrated the highest yield parameters, fresh weight of leaves (24.40 gms), leaves yield/bag (50.54 g). Additionally, T2 exhibited better quality parameters such as total soluble solids (3.23 °Brix), shelf-life (4.67 days), and chlorophyll content (56.40 nmol cm2), while the lowest values were observed in T4 (LED Full spectrum).
