Response of broccoli to sulphur application at topdressing in the presence or absence of organic compost at planting

Abstract

The literature has confirmed the efficacy of sulphur (S) when growing Brassicaceae. However, there are no studies with this nutrient on broccoli. Therefore, the aim of this study was to evaluate the response of broccoli (hybrid Avenger) to sulphur rates applied at top dressing in the presence or absence of organic compost at planting. The experimental design was a randomized complete block, with ten treatments (5 x 2 factorial design) and four repetitions. Treatments consisted of five S (ammonium sulphate) rates (0, 31, 62, 93 and 124 kg ha

Comparative effect of different irrigation levels and soil amendments on cabbage productivity in semi‐arid Central Namibia

“…In Experiment 2, a different variety (Menzania) was used due to the unavailability of the Star 3301 F1 hybrid variety on the market. Cabbage was selected as test crop due to its high nutritional requirement and responsiveness to different soil treatments (Carla et al, 2016).…”

“…Therefore, in this experiment, the HH meal served as the N source, while the B meal served as the P source in the HHB meal treatment. In addition, biochar, zeolite, HHB meal and compost were applied at 20 (Hossain et al, 2020; Toková et al, 2020), 14 (Chen et al, 2017; Zheng et al, 2018), 2 (Wang et al, 2017) and 97 t ha −1 (Carla et al, 2016; Papafilippaki et al, 2015), respectively. The Be‐Grow boost (L) hydrogel was applied at 44 kg ha −1 (1 g per planting hole) (Yang et al, 2019) at a depth of 20 cm.…”

“…Different soil amendments, such as compost and biochar, have been suggested for optimal vegetable production by various researchers (Abdrabbo et al, 2015; Cataldo et al, 2021; Laghari et al, 2016; Şeker & Manirakiza, 2020; Widowati et al, 2020). Organic fertilizers such as compost and hoof and horn (HH) meal serve as sources of soil nutrients for plants (Carla et al, 2016; da Silva et al, 2019; Oluwafisayo & Olusegun, 2023; Papafilippaki et al, 2015). In addition, soil conditioners such as zeolite, biochar and hydrogel polymers can improve nutrient retention and holding capacities and cation exchange capacity (CEC) (Aainaa et al, 2018; Agegnehu et al, 2016; Chen et al, 2017; McDonald et al, 2019; Mondal et al, 2021; Oladosu et al, 2022; Zheng et al, 2018) and regulate the pH of sandy soils (Faloye et al, 2019; Hossain et al, 2020), leading to improved crop production (Akolgo et al, 2020; Nurhidayati et al, 2016; Šimansky et al, 2021).…”

Production of Chives Using Organic Fertilizers before Planting and in Top Dressing

“…Interest in organic fertilizers and research demonstrating gains in productivity and better soil characteristics with their use has increased in recent years [4,5,6,7,8]. However, most of this research has been done with fertilizer applied before planting, and researches about organic fertilizers in top dressing are scarce, but most of them has shown the importance of organic top dressing fertilization [8,9].…”
