The application of balanced fertilizers is essential to produce highquality broccoli. A field experiment was conducted to find an appropriate fertilizer management practice for broccoli (Brassica oleracea L. var. ‘Italica’) that can generate higher yield and quality. The experiment comprised 24 treatment combinations with six fertilizer management practices, i.e., T1: control. T2: cow dung at 10 t ha-1. T3: chicken manure at 10 t ha-1. T4: recommended NPK dose. T5: cow dung at 5 t ha-1 + 50% of the recommended NPK dose. T6: chicken manure at 5 t ha-1 + 50% of the recommended NPK dose. The highest plant height (60.00 cm) occurred in response to T6, the highest stem length (22.25 cm) in T4, and the maximum number of leaves per plant (22.00) in T4 and T6 treatments. Maximum fresh leaf weight per plant (609 g), stem diameter (3.98 cm), curd diameter (16.63 cm), and individual curd weight (494.50 g) occurred in response to the T5 treatment. The optimum yield (25.78 t ha-1) of broccoli can be obtained by application of cow dung (5 t ha-1) with a recommended dose of 50% inorganic fertilizer NPK (T5). Maximum TSS value (10.54%) occurred in response to T3, which was statistically similar to the effect of T6 (10.52%). Vitamin C content (80.77 mg 100 g-1) became significantly high in response to the T4 treatment (100% recommended dose of NPK). Minimum vitamin C content (53.84 mg 100 g-1) occurred in the control treatment (T1). Applying cow dung at 5 t ha-1 in addition to the 50% recommended dose of NPK fertilizers (T5) led to superior yield values in broccoli.

The study was conducted in Polashi, Manirampur Upazila, Jashore, Bangladesh, during Rabi seasons of 2020-2021 and 2021-2022 to evaluate the effects of organic nutrient sources on yield and shelf life of broccoli. The experimental layout was a Randomized Complete Block Design (RCBD) with three replications and six treatments which were: T1= Vermicompost 3 t ha-1, T2 = Vermicompost 4 t ha-1, T3 = Trichocompost 3 t ha-1, T4 = Trichocompost 4 t ha-1, T5 = FYM 12 t ha-1, T6 = (control). A Completely Randomized Design (CRD) was designed to determine the shelf life of broccoli with three replications, considering three factors, (i) the effects of organic sources of nutrient, (ii) storage materials at room temperature and (iii) storage materials at cold storage condition. The findings revealed that the effects of organic nutrient sources significantly influenced the yield and shelf life of broccoli. The treatment T2 (vermicompost 4 t ha-1) produced significant (p≤0.05) amounts of marketable curd yield of broccoli (22.33 t ha-1 and 21.27 t ha-1), followed by T4 (Trichocompost 4 t ha-1) with marketable curd yield (19.76 t ha-1, 18.78 t ha-1). In contrast, the minimum marketable curd yield (7.76 t ha-1 and 7.29 t ha-1) occurred in T6 (control) in the respective years. The treatment of T2 led to the highest shelf life (7.33 and 7.55 days) at room temperature (14-220C with RH 60-65%). At cold storage (40C with RH 90-95%), using High-Density Polyethylene (HDP;15 micron) vacuum pack, the shelf life was also significant (24.75 & 25.19 days) during the years of 2020-2021 and 2021-2022, respectively.
