“…In contrast to our findings, a study from Mexico [28] reported significantly lower values of okra fruit weight (7.3-15.3 g). A lower AW was similarly reached in studies conducted in Pakistan [29] using 5 okra cultivars (8.2-10.1 g), India [30] using 7 cultivars (11.3-17.2 g), Egypt [31] using 5 cultivars (5.7-11 g) and Bangladesh [32] using 14 cultivars (14.0-17.8 g). In a study [33] in Nigeria using two cultivars, a higher AW of okra fruits was shown compared to previous studies (20.4-22.6 g).…”

Climate change, linked with an increase in temperature, contributes to the possibility growing of non-typical and lesser-known vegetable species in the Slovak Republic, including okra. Seven okra cultivars were tested as part of this study, which focused on the basic yield parameters, antioxidant activity and total polyphenol content in okra fruits. The statistical analysis of obtained results revealed significant differences in all monitored parameters of okra. The selection of “plastic” crop cultivars that can produce a steadier yield in each growing year is required due to the significant climate variations between growing seasons. In this regard, the okra cultivar ‘Baby Bubba’ can be recommended. The results also showed the high antioxidant activity and polyphenol content of okra pulp and seeds. Okra has a higher nutritional quality than other vegetable species frequently grown in the Slovak Republic. Okra cultivars ‘Burgundy’, ‘Pure Luck F1’ and ‘Jing Orange’ can be suggested from a nutritional perspective. Finally, it is possible to state that okra cultivars showed good yield potential and nutritional quality compared to the studies realized in countries in which okra is known and commonly used by the human population.

“…Various studies with okra showed lower Y/P. In a study [29] in Pakistan, Y/P varied from 99.2 to 156.8 g, dependent on the okra cultivar. The Y/P (seven cultivars) ranged from 144.6 to 238.8 g in a study in India [30].…”

In order to improve carrot quality and soil nutrition and reduce the environmental pollution caused by intensive carrot production, more comprehensive combined water–fertilizer management strategies are necessary. This study hypothesizes that optimal management of water and fertilizer can improve carrot yield and quality and reduce greenhouse gas emissions and soil nutrient residues. Thus, coordinated water–fertilizer management strategies were tested for carrot production on the North China Plain over two consecutive growing seasons. Four treatments were tested: local standard fertilization and irrigation practices (FNP); optimized irrigation and chemical nitrogen, phosphorus, and potassium fertilizer (OPT); OPT treatment with partial replacement of chemical fertilizer with peanut shell (PS); and OPT treatment with partial replacement of chemical fertilizer with mushroom residue (M). Compared to the FNP treatment, there were statistically significant increases in soluble sugars (12–27%) and free amino acids (14–26%), and decreases in the nitrate content (7–17%) of fleshy root in the OPT, PS, and M treatments. In autumn carrots, the OPT and M treatments decreased yield, whereas PS increased yield; spring carrot yield was significantly decreased in the OPT, PS, and M groups compared to the FNP group. There were no significant effects of the treatment group on carrot growth rates, nutrient accumulation, or nutrient distribution. However, the OPT, PS, and M treatments were associated with significantly increased partial productivity of phosphate fertilizer (233–363%), reduced residual levels of nitrate and available phosphorus in the top 80 cm of soil, and decreased greenhouse gas emissions by 8–18% compared to the FNP treatment. These results highlight the effectiveness of partial organic fertilizer substitution and integrated water–fertilizer management to produce high-quality carrots with minimal environmental damage.

This research aimed to assess the influence of various chemical and organic fertilizers on the vegetative and reproductive characteristics of the New Kuroda variety of carrots (Dacus Carota). The study included the recommended NPK dose (80:60:60 kg/ha), individual components of N (80 kg/ha), P (60 kg/ha), K (60 kg/ha), as well as organic sources such as goat manure (15 t/ha), FYM (20 t/ha), and a control group without any fertilizer. Measurements of growth and reproductive traits were taken at 45, 55, 65, 75, and 85 days post-sowing. Results indicated that the recommended NPK dose consistently outperformed other fertilizer sources in enhancing both vegetative and reproductive parameters. The highest yield of 10.94 tons/ha was achieved with NPK fertilizer, while organic sources like goat manure demonstrated the second-highest growth and development traits. The control group exhibited the lowest growth and development parameters. These results show that these fertiliser sources have a considerable favourable influence on the vegetative and reproductive development of the New Kuroda carrot variety. The outcomes indicate how various fertiliser sources may significantly improve the vegetative and reproductive development of the New Kuroda carrot; the recommended dosage of NPK in conjunction with the supply of goat manure fertilizer stands out as very appropriate techniques for producing carrots. This illustrates how applying a balanced dosage of these fertilisers may lead to increased carrot yield.
