The effects of various rates of nitrogen, phosphorus, and potassium on the boron concentration of leaf tissue of cauliflower (Brassica oleracea var. botrytis L. ’Snowball Y’), Brussels sprouts (Brassica oleracea var. gemmifera Zenker ’Jade Cross’) and peas (Pisum sativum L. ’Dark Skin Perfection’) were investigated at several locations in Prince Edward Island. Except for N on cauliflower, B concentrations of leaf tissues of these crops were not greatly affected by the N, P, or K treatments. Applied N increased the B concentration of cauliflower leaf tissue at eight of the nine locations investigated.

Brussels sprouts (Brassica oleracea var. gemmifera DC., Jade Cross) require no potassium fertilizer on Prince Edward Island soils if exchangeable soil K as determined by neutral 1 N ammonium acetate exceeds 100 ppm. Below 75 ppm exchangeable soil K, 186 kg K/ha must be applied for maximum yields. Potassium treatments increased yields at only three of 12 locations studied. Leaf tissue potassium concentration was significantly increased at all locations by the fertilizer treatments. Neutral 1 N ammonium acetate for determining exchangeable K was the best soil analysis extract among those tested for measuring available potassium. Tissue analysis gave no information beyond soil analysis for predicting potassium fertilizer requirements on any soil studied.

To reduce nitrogen (N) losses from vegetable fields, fertilizer recommendations should be adjusted according to the large range in yield and thus in N uptake of vegetable crops. Therefore, a model was used to predict total N uptake based on expected yield. The model has been validated successfully in a series of studies for Brussels sprouts (Brassica oleracea L. var. gemmifera), white cabbage (Brassica oleracea L. var. capitata) and kohlrabi (Brassica oleracea L. var. gongylodes). The objective of this study was to validate the model for table beet (Beta vulgaris L. var. conditiva), a crop with a considerable variability in N uptake, which is caused by a large potential range of selecting sowing dates, plant densities and cultivars. Field experiments were carried out over two years. Fifty-five combinations of N fertilizer levels, plant densities, cultivars and sowing dates were tested. Plants were sampled at 2- or 3-week intervals, and fresh matter, dry matter and N content of leaves and roots were measured. Crop specific model parameters for table beets were determined from independent data. The model wverestimated N uptake for N-limiting conditions, but for optimally fertilized table beets measured and estimated N uptake showed a close correlation (R2 = 0.93) when total yield was used as an input parameter for the model. Although the error of estimation (35 kg·ha-1) was considerable, studies with other vegetable crops using the model found the error even higher if other tools, such as look-up tables, were used for predicting N uptake.

The effects of nitrogen, phosphorus, and potassium on the yield and maturity of cauliflower (Brassica oleracea L. ssp. botrytis cv. Snowball Y) were investigated at a total of nine locations during three successive cropping seasons. Yields were substantially increased at most locations by applications of nitrogen and phosphorus but were only slightly affected by applied potassium. Maturity was slightly delayed by a lack of phosphorus. Maximum yields were generally obtained where N was applied at 112–224 kg/ha, P at 49–98 kg/ha, and K at 93 kg/ha.

Vegetable growing is one of the most important and, at the same time, the most complex plant growing branches of agriculture in Ukraine. Firstly, this is due to the value and irreplaceability of vegetable products for human nutrition, which determines the spread of vegetable crops in all regions of the country and the allocation of large areas of agricultural land for their cultivation. On the other hand, a feature of the industry is low transportability and high labor intensity of vegetable production, a large set of cultivated vegetable crops and the mechanization of individual production processes of their cultivation, in particular harvesting, is complicated. Therefore, it is very important to expand better than the cultivation of new vegetable crops, the cultivation areas of which are currently relatively small. One of these crops is Brussels sprouts, which is characterized by excellent nutritional and medicinal properties, but whose cultivation areas are insignificant, due to insufficient study of the characteristics of crop cultivation. Brussels sprouts (Brassica oleracea var. Gemmifera) - vegetable crop. Traditionally regarded as a variety of the species Cabbage (Brassica oleracea) of the genus Cabbage (Brassica) of the Cabbage family (Brassicaceae), some modern sources do not consider Brussels sprouts as an independent species, but consider it a group of varieties of the species Brassica oleracea L., with this approach, the correct name of this group considered Brassica oleracea Gemmifera Group.

AbstractQuantitative X-ray microanalysis for nine elements has been carried out on frozen, fully hydrated fracture faces of upper and lower epidermis, palisade and spongy mesophyll cells in leaf tissue of Nicotianatabacum L. cv. Coker 319 taken from plants at five different stages of growth. Although concentrations of aluminium, silicon and chlorine generally fell below the minimum-detection limit, the values for sodium, magnesium, phosphorus, sulphur, potassium and calcium were consistently higher and showed differences among tissue types and stages of growth. The general trend was for elemental concentrations to increase up to the mature and ripe stages of growth and then to decrease as the leaf ages further. The sodium values were highest at the beginning and end of the five stages of growth, with higher amounts in the epidermal tissues. As the leaves age, the levels of magnesium fell in the photosynthetic tissues but increased in the epidermal tissues. Such changes could be correlated with higher concentrations of potassium at the early stages of growth and with much lower values at the late stages. The sulphur levels showed only small differences between tissue types at all stages of growth. The calcium levels increased with age and there were consistently higher concentrations in the photosynthetic tissues than in the two epidermal layers. The levels of phosphorus were low in all tissue types and decreased with age. There is an increasing positive correlation between phosphorus and magnesium and a decreasing positive correlation between phosphorus and potassium during growth and senescence.

The effects on succeeding crops of nitrogen in residues returned to the soil of brassica vegetable crops (Brassica oleracea) were studied on a nitrogen-retentive silt loam soil at Horticulture Research International, Kirton, Lincolnshire, UK. A sequence of four crops was started in 1988 and again in 1989. In the first sequence, two successive cauliflower crops (Brassica oleracea cv. botrytis L.), crops 1 and 2 in the first year, were followed by Brussels sprouts (Brassica oleracea cv. Gemmifera D.C.), crop 3, in the second and spring barley (Hordeum vulgare), crop 4, in the third year. The second sequence, started in spring 1989, was on an area adjacent to the first, but with spring wheat (Triticum aestivum) as crop 4. The sites followed an unfertilized, 1-year grass ley (1987) or spring barley (1988) with 73 and 107 kg N/ha soil mineral nitrogen (SMN, NH4+NO3) in the 0–90 cm soil profile at the start of each sequence. The marketable yield of the first cauliflowers in both sequences increased with fertilizer nitrogen up to 240 or 300 kg/ha. The response of the second cauliflower crop to fresh N declined with increasing amounts of SMN (0–90 cm) at planting, with no response when SMN exceeded c. 270 kg N/ha. Crop 3 apparently responded to fresh N in sequence 1 but not in sequence 2 even though SMN at planting ranged up to c. 400 kg N/ha. This difference in response was largely explained by the amount and distribution of SMN in the 0–30 and 30–60 cm layers when the sprouts were planted. Soil mineral N to 90 cm when the cereals were sown was only c. 100 kg N/ha, which did not reflect the large amounts of N applied to the previous crops. In spite of this, barley yield without any fresh fertilizer N did vary with the amounts of N applied to the previous crops. The results showed that SMN was a useful predictor of fertilizer response in some, but not all, situations. To use SMN more generally requires interpretation using dynamic simulation models.

Trellis graphics (Becker, Cleveland, and Shyu, 1996) is a very effective method for visualizing multidimensional data sets. The basic idea behind trellis graphics is to display any of a large variety of 1-D, 2-D or 3-D statistical plot types in trellis layout of panels, where each panel displays a subset of the data for different values of one or more additional discrete or continuous conditioning variables. The data that we use for the illustration of different applications of trellis graphics are the results of a field experiment conducted at the Institute for Field and Vegetable Crops in Novi Sad in the period 1994–1998 (Čobanović et al., 2001) with three fertilizers (nitrogen, phosphorus and potassium) in three repetitions with nine variants of wheat. In the experiment, four quantities of each fertilizer were applied (0, 50, 100, 150 kg/ha) at plots of the same size in 20 from 64 possible combinations, whereby the yield of wheat (t/ha) was the measured outcome.
