“…However, the uptake of plant nutrients depends on several factors, such as cultivar, crop environment, soil fertility, fertilization methods ( Zink 1966;Salo et al 2002;Lee et al 2009a;Yoldas et al 2011). According to Fink et al (1999) and Lee and Lee (2014), production of bulbs as much as 60 t/ha takes up 108 kg/ha of N, 21 kg/ha of P, 120 kg/ha of K and 9 kg/ha of Mg, while 5 t of harvest residues remove 15 kg/ha of N, 1 kg/ha of P, 9 kg/ha of K and 1 kg/ha of Mg. In southern Italy (Caruso et al 2014), yield of onion bulbs as much as 50 t/ha can be achieved supplying 70 kg/ha of N as ammonium sulphate, 80 kg/ha of P 2 O 5 as superphosphate and 130 kg/ha of K 2 O as potassium sulphate before transplanting; 130 kg/ha of N and 140 kg/ha of K 2 O as calcium nitrate and potassium nitrate on dressing.…”

Sekara A., Pokluda R., Del Vacchio L., Somma S., Caruso G. (2017) The aim of this review is a wide description of the relationships between growing conditions and bulb yield and quality of onion (Allium cepa L.), focused particularly on long-day cultivars suitable for storage. Marketable yield decreases according to the reduction of crop length caused by the increase of growth temperature. The nutritive requirements of storage onion are highest during the vegetative growth. The application of humic substances and the inoculation of mycorrhizae may enhance bulb growth and quality, mainly under stress conditions. Onion is a slow-growth, shallowrooted crop with non-shading habitus and therefore its productivity is highly dependent on water availability in the soil, proper fertilization and weed control. The shelf-life of onion bulbs is a genetic trait, improvable by efficient crop and post-harvest management, and adequate conditions of bulb storage. The quality of storage onion bulbs is ascribed to several indicators, such as thiosulfonates, pyruvic acid, soluble solids, sugars, and many other biological compounds. This review is also focused on onion quality as affected by the interactions among genotype, environment, farming practices and post-harvest management.

“…From an experiment performed on 22 kinds of vegetables by Fink et al . (), we calculated the average amounts of nutrient removal, which were N 202 kg/ha/crop, P 32.2 kg/ha/crop and K 274 kg/ha/crop. Wichmann () reported that winter wheat in a rice/wheat cropping system produced 13.7 t/ha total dry matter (grain 6.7 t/ha) and removed 187 kg N, 24.0 kg P and 210 kg K from the soil, while the rice crop produced a grain yield of 8.8 t/ha and removed 235 kg N, 40.2 kg P and 280 kg K. We used the average nutrient removal by these two crops of 211 kg N/crop, 32.1 kg P/crop and 245 kg K/crop as the standard for the rice/wheat cropping system in this study.…”

Intensive vegetable cultivation has developed very rapidly in China, and investigation of current soil nutrient problems in vegetable fields and their potential environmental risk is important for local soil nutrient management strategies. Three hundred and sixty-six soil samples were collected from greenhouse vegetable fields, open vegetable fields and rice/wheat rotation fields in southern Jiangsu Province, the most intensive vegetable-producing areas in Yangtze River Delta, China, for the analysis of their soil fertility status. Soil acidification and P enrichment were the main problems identified in this area of vegetable production, with about 20 and 17% of the open and greenhouse vegetable field soils, respectively, being extremely acid with soil pH values below 5.0. In contrast, no soils under rice/wheat rotation fields were as acidic. Percentages of sites with Olsen-P concentrations < 90 mg/kg were 61, 85 and 0% for soils growing greenhouse vegetable, field vegetable and rice/ wheat, respectively. The nitrogen (N) surplus for vegetable fields exceeded 170 kg/ha/crop, and the phosphorus (P) surplus exceeded 40 kg/ha/crop. Thus, current vegetable production leads to potential environmental risks of N and P pollution of nearby aquatic bodies. Insufficient supplementation with potassium fertilizers was found in some vegetable fields. Several ameliorative measures are proposed.

“…Magnesium is an important component of chlorophyll and a great impact factor for green plant's photosynthesis, thereby green pant's photosynthesis would be held back and crop's yield and quality would be decreased while soil's magnesium is deficient [1][2][3][4]. Many studies have pointed out that magnesium deficient is a common item in red-soil vegetable field in South China for its individual climate and soil property [5][6][7].…”

Magnesium deficiency is a common item in red-soil vegetable field in the south of China, and it has few studies about effects of applying magnesium fertilizers on vegetable's growth this region. So, a field trial, with applying different rates of magnesium fertilizers on the basis of farmer routine fertilization, was conducted to test the effects on vegetable's yield, nutrient elements' uptake and soil's basic fertility in a red-soil vegetable field. Results showed that, with the application of magnesium fertilizer (magnesium sulfate, 112.5~450 kg/hm 2 ), Chinese cabbage's yield, and the amount of nitrogen, phosphorus, potassium and magnesium absorbed by vegetable were increased obviously. Moreover, the contents of total magnesium and exchange magnesium in vegetable-field soil after harvest were enhanced greatly.
