In this study, a simulation experiment by farm warming with infrared ray radiator was carried out, and results showed that the broad bean (Vicia faba L.) growing days were shortened by increased temperature. The seedling, ramifying, budding, blooming, podding, and maturing stages were shortened by 1–4, 1–2, 1, 2–3, 1–2, and 2–4 days, respectively, and the whole growing period was shortened by 7–16 days when the temperature increased by 0.5–2.0°C. The broad bean yield increased by 10.1–16.6% when the temperature increased by 0.5–1.0°C, and significantly decreased by 38.1–90.1% when the temperature increased by 1.5–2.0°C. Increased temperature significantly improved the fat, carbohydrate, ash and energy contents.

Gibberellic acid (GA4+7) was applied to cauliflower crops of the cultivars Delira and Elgon, grown in spring and summer of the years 1984, 1985 and 1986. Observations were made on the timing of the end of the juvenile phase and of curd initiation, the final number of leaves and the total length of growing period. In most crops the period between transplanting and harvest was shortened when GA4+7 was applied twice after the end of juvenility at a concentration of 80 mg/litre. The extent of shortening of the growing period increased with increasing difference between the number of leaves initiated at the time of application and the final number of leaves of the untreated crop. GA4+7 reduced the final number of leaves. Quality of the curds was unaffected by the treatment in most harvests, but the bracting incidence was reduced. In crops of cv. Delira with a low final number of leaves, size and quality of the curds was reduced. The results are discussed in relation to harvest planning of cauliflower.

Abstract The effect of foliar feeding with two fluid multicomponent fertilizers was investigated: Florovit and Ekolist Warzywa + Urea on the yield and quality of three medium-fruit-size melon cultivars (‘Charentais F1’, ‘Melba’, ‘Fiesta’). Weather conditions in the consecutive years of the study had a significant influence on the yield level and quality of fruit. A higher yield of better quality was achieved in the years 2005 and 2007. That period was characterised by relatively high air temperature and low rainfall towards the end of the growing period of melon. The fertilizers applied in the experiment significantly influenced melon yielding. The plants fertilized with Ekolist Warzywa + Urea provided a higher marketable yield of melon fruit than the plants fertilized with Florovit. When applied, this fertilizer also caused an increase in flesh thickness and fruit flavour as compared with Florovit feeding. Foliar feeding with both studied patterns increased the average fruit weight and number of marketable fruit as compared to the non-fertilized treatment. Among the studied cultivars, ‘Fiesta’ gave the highest marketable yield and the best quality fruit.

Yield And Quality

Owing to overexploitation, wild resources of Astragalus mongolica, a Chinese herbal plant that is widely distributed in the arid and semi-arid areas of Northern China, have gradually become exhausted, and therefore, commercial cultivation is increasingly important to meet the growing demand for astragalus and reduce the pressure on wild populations. Nitrogen level is an important factor that affects the yield and quality of A. mongolica. However, uniform standards for fertilization among production areas have not yet been determined. In this study, the effect of nitrogen fertilizer treatment on the yield and quality of A. mongolica in the Qinghai-Tibet Plateau was explored using a control treatment (no added nitrogen, N0) and five different nutrient levels: 37.5 kg/ha (N1), 75 kg/ha (N2), 112.5 kg/ha (N3), 150 kg/ha (N4), and 187.5 kg/ha (N5). According to grey relational analysis, the optimal nitrogen fertilizer treatment was the N4 level followed by the N5 and N2 levels. Nitrogen fertilizer significantly increased the root biomass, plant height, root length, and root diameter. However, nitrogen fertilization had no significant effect on the content of Astragaloside IV and mullein isoflavone glucoside. The content of ononin and calycosin continually accumulated throughout the growing period. The results showed that the ononin and calycosin content under N4 and N2 is higher than other levels and there is not significantly different between different nitrogen fertilizer levels about them. The content of formononetin decreased gradually with the progression of the growing season. The optimal nitrogen fertilizer treatment for A. mongolica is recommended to be 150 kg/ha and the content of active compounds and yield were observed to reach the maximum in October.
