Effect of Fertigation Intervals on Plant Growth and Flower Yield of Multiflora Chrysanthemum (Chrysanthemum morifolium) cv. Branfountain Purple

This study was conducted in the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology and Sciences, Prayagraj (UP) from October 2021- March 2022 to investigate Effect Fertigation Intervals on Plant Growth Flower Yield Multiflora Chrysanthemum (Chrysanthemum morifolium) cv. Branfountain Purple. The experiment laid out RBD with nine treatments which were replicated thrice. results revealed that treatment T9 (19:19:19 NPK/m2(4.6 g) @ 8 days interval)) + foliage spray 0.2% EDTA Chelated micronutrient mixture) – performed best terms plant height(cm) (21), number branches (53), spread (cm) (27), Number leaves (403), flowers per (75), chlorophyll content (SPAD value) (31.9), first flowering (days) (130), 50% (143), duration (185), flower diameter (4.0), individual weight (g) (10), yield (g/plant) (0.78). Therefore, (T5+ when compared other treatments. Overall application fertilizer through fertigation as NPK/m2 (4.6 proved be better for different growth multiflora chrysanthemum.
