MINERAL CONTENT OF MELON FRUIT (CUCUMIS MELO L.)
Melons are highly demanding, thermophilous plants, which is why they are unpopular among fruit growers. Melon cultivation requires special treatment methods for the improvement of microclimatic conditions. Seven Polish melon cultivars are presently grown on the domestic market. They are well adapted to the local climate. The growth rate, vigor, fruit shape, fruit size, rind color and flesh thickness of those cultivars vary. The objective of this study was to determine the mineral content of edible parts of four field-grown melon cultivars in the Warmia region (NE Poland). This study discusses the mineral content of melon fruit subject to the investigated cultivar and cultivation method. In Poland, melon production is difficult and unreliable. The main problem is the selection of an appropriate cultivar and cultivation method. The analyzed material consisted of four Polish melon cultivars: Malaga F1, Melba, Oliwin, Seledyn F1, grown in a field experiment without protective cover, under polyethylene (PE) sheet cover, under non-woven polypropylene (PP) cover, with soil mulching, as well as with soil mulching under PE sheet cover or nonwoven PP cover. The highest concentrations of total N, K, Ca and Cu were determined in melon fruit of cv. Oliwin. Significant variations in total nitrogen and phosphorus levels in the edible parts of melon plants were noted subject to the applied cultivation method. Cucumis melo L. grown in the control treatment without protective cover was marked by significantly higher levels of total nitrogen and phosphorus in the fruit, compared with fruit grown with the use of other cultivation methods. The results of this study indicate that the fruit of melon plants cv. Seledyn grown in mulched soil under non-woven PP cover was characterized by the most favorable Ca:Mg and Ca:P ratios in comparison with fruit from the remaining treatments.
Content of Basic Nutrients and Minerals in Heads of Selected Varieties of Red Cabbage (Brasicca oleracea var. capitata f. rubra)
The presented results concern three varieties of red cabbage: koda, kissendrup SwE and haco POl. during a field experiment conducted in 2003-05, the three varieties were analyzed for their organic and mineral content which is responsible for the nutritive value of cabbage. Significant differences were found between the studied varieties. The reported changes accounted for organic and mineral nutrients. The best results were reported in respect of var. haco POl, whose edible parts were the richest in dry matter, vitamin C, sugars and organic acids. haco POl was also characterized by the highest copper content and the lowest iron content among the analyzed varieties.
Quality changes in curds of white, green, and romanesco cauliflower during storage
The work contains a short characterisation of customers' behaviour on the market of selected dairy products. An attempt was made at an identification of the factors shaping the conduct of purchasers. It has been shown that customer satisfaction should become one of the main objectives of the enterprise. Customer satisfaction, including its measurement, constitutes part of an overall evaluation of the firm's effectiveness and productivity. The study of satisfaction shows whether the enterprise has planned and realised its calculably defined objectives pertaining to the customer. The correlation between the customer satisfaction and the volume of sales is an argument strongly supporting the policy of turning in the direction of using customer satisfaction, and to be more precise, the information obtained by analysing its measurement in planning, supervision and innovation of the firm's systems. An adequate determination of the value expected by the customer will be decisive in achieving success by the firm. The value should be understood in terms of consequences (customer's hierarchy of values) and not in terms of the product's attributes. Getting to know the customer will allow the enterprise to influence their conduct via suitable strategies, in particular product strategies, prices, distribution and promotion.
