Effect of Different Micronutrients on Plant Growth, Yield and Flower Bud Quality of Broccoli (Brassica Oleracea Var. Italica)

Abstract

A field experiment was conducted to study the “Effect of different micronutrients on plant growth, yield and flower bud quality of broccoli (Brassica oleracea Var. Italica) cv. – Green Bud” during rabi season of 2014-15 Research field, Department of Horticulture, Allahabad School of Agriculture, Sam Higginbottom Institute of Agriculture, Technology and Sciences Allahabad. The experiment consists of 10 treatment viz, T0 (control), T1 (B), T2 (Mo), T3 (Mn), T4 (B + Mo), T5 (B+ Mn +Zn), T6 (Mo +Mn), T7 (B +Mo +Mn +Zn), T8 (B +Zn), T9 (Zn) laid out in Randomized Block Design (RBD) with three replications. The micronutrients (B, Mo, Mn and Zn) were applied at the rate of 2 kg (B), 0.5 kg (Mo), 2.5 kg (Mn), 3 kg (Zn) per hectare significantly increased the plant height (51.30 cm), number of leaves(22.92), Plant spread (52.83 cm), diameter of bud or head (16.90 cm), average bud weight of per plant (303.69 gm), yield ha-1(121.48q), vitamin ‘C’ (93.92 mg), TSS (0Brix) (8.37) content, Plant fresh weight (908.28 gm), dry plant matter(95.61 gm), root weight (45.02 gm) and dry weight(11.65 gm) were maximum in treatment T5 and lowest in T0 (control) under Allahabad agro climatic condition.

Effect of foliar feeding of micronutrients on growth and yield of cauliflower (Brassica oleraceae var. botrytis L.) cv. Ragini under net tunnel

“…T7RDF +Boric acid (B)@0.2%+ Ammonium molybdate (Mo)@0.Similar result was also observed bySingh et al (2017) …”

“…Observations were recorded on plant height, number of leaves per plant, days to curd initiation, days to 50% curd maturity, curd diameter, curd depth, curd yield. [13] and Sitapara et al (2011) [14] in cauliflower.…”

Cauliflower Growth, Yield and Quality Response to Nitrogen Fertilization and Micronutrients Foliar Application in Newly Reclaimed Areas

“…Interestingly, neither nitrogen levels nor micronutrient application had altered the trait of number days to maturity (Table 2) over the two growing seasons. Contrary, Singh et al (2017) reported that soil application of Borax (20 kg/ha) combined with Sodium molybdate (2 kg/ha) as sources of B and Mo, respectively, accelerated the early mature yield of cauliflower. However, insignificant effects of nitrogen, micronutrient application and their interaction on number of days to maturity might be due to its high heritability, whereas, it was reported that number of days to budding is a highly heritable trait (86 and 94%), which indicates that this trait is stable and not strongly affected by environmental factors (Yousef et al, 2015;Thorwarth et al, 2018).…”

Effect of different micronutrients and stage of their application on yield and quality of cauliflower (Brassica oleracea var. botrytis)

“…As a result the leaf blade fails to develop properly and only the midrib portions develop resulting sword like appearance of leaves giving whiptail symptom. (Singh et al 2017) [12] .…”
