Value of broccoli inflorescences is high due to the rich content in carbohydrates, vitamins and minerals. Broccoli culture is practiced in open field and in protected areas. Transylvania climatic conditions are favorable for the cultivation of this species. Broccoli cultures are started with seedlings and this is leading to additional costs for their production. Experience was conducted in 2010-2011, in Reghin, Mures County. Experimental factors were time of planting and the culture method. Experimental culture was established at different times (April, May, June) by two methods (by planting seedlings and direct sowing).

Given that in most cases, mushrooms are grown on different substrates of solid consistency, and most supplements containing mycelium from the Cordyceps militaris mushroom are obtained by drying and shredding the mycelium, which has been grown on a solid substrate consisting of brown rice flour or other cereals, so that they very often contain more starch than active ingredients. In this paper we looked at the influence of temperature and pH level on the growth of the mycelium of this mushroom in liquid culture media. The development of liquid mycelium cultures was tested at temperatures between 20-30 °C and at a pH level between 5-7. The highest amount of mycelium was obtained from samples raised at 26 °C and a pH level of 5.5.

Saccharate (Sturt.) and can be distinguished from normal corn by presence of one or more mutant genes that affect carbohydrate metabolism in endosperm. Purpose of this research is to compare behavior of sweet corn hybrids created at SCDA Turda, but also foreign hybrids, in terms of quality elements and chemical composition, in conditions of Transylvania plateau, in two localities: Turda and Viişoara. As biological material following domestic sweet corn hybrids were chosen: 'Prima', 'Estival', 'Deliciul verii', 'Dulcin', 'Delicios', 'Estival M' and foreign hybrid 'Jubilee'. These hybrids were also analyzed in terms of chemical composition. Weight of 'Estival' hybrid has the best behavior in both localities; as regards to cobs length, 'Delicios' hybrid has registered increases very significant positive, differences between plant height in the two localities confirm significant influence of environment on formation of this important typical qualitative characteristics, highest performances in terms of β-cryptoxanthin and zeaxanthin content, are recorded by 'Jubilee' in both localities, 'Deliciul Verii' hybrid records significant value for lutein content, also recording an important addition of carbohydrates in Turda, 'Prima' and 'Estival' hybrids recorded highest values of sucrose in both localities.

Addressing some issues regarding the behavior of agronomic characters of production in a set of hybrids may lead to recommendations on the choice of the most suitable hybrids for growing in Transylvanian Plateau. Thus, in 2016, we set up an experience in two locations of Cluj county, Turda and Viişoara, on the lower terrace of Arieş river. Biological material chosen for this study was represented by seven hybrids, of which six indigenous Prima, Estival, Estival M, Dulcin, Deliciul Verii (released by SCDA Turda), Delicios (INCDA Fundulea) and foreign hybrid Jubilee (produced by Syngenta). The earliest hybrids Prima and Estival, have the lowest average number of grains/row, with very significant differences compared to control (experience average). Estival, Estival M and Jubilee hybrids show the highest number of rows of grains/cobs, with very significant differences over the average.

The highest value concerning the medium number of leaves was obtained at the tomato hybrid Shannon F1 (28.55). The blossoming and fruit link of the first 3 clusters on the tomato plants recorded the highest percent at the Menhir F1 (80/40 cm) tomato hybrid (90.79 %). The same experimental variant has the highest percent in blossoming and fruit link from the cluster number 4 till 8. (54.84 %) and the total one. The early production is influenced by the plant density 80/30 cm-41.700 plants/ha, with a medium yield of 2.47 kg/m 2. The same plant density in interaction with the tomato hybrids obtained a significant difference (3.18 kg/m 2 medium early yield-(interaction between plant density 80/30 cm and Cronos F1 tomato hybrid). The interaction between tomato hybrids and adopted plant density lead to no statistical differences. The total yield was influenced by the plant density adopted with a medium yield of 19.26 kg/m 2 at the plant density of 80/30 cm. The interactions between densities and tomato hybrids lead to statistical significance in case of Cronos F1 tomato hybrid planted at a density of 80/30 cm-41.700 plants/ha (20.46 kg/m 2 total yield), and at the same density but a different tomato hybrid, Shannon F1 (19.23 kg/m 2 total yield).

From the Brassicaceae group, kale is the most valuable in terms of nutrition. The therapeutic qualities of kale are recognized since antiquity by Hippocrates, Pliny the Elder, Cato the Elder, Galen. Kale was considered a panacea by the romans. The main purpose of this paper was to establish an optimal sowing date that ensures the highest yield, adapted to the specific environmental factors of Transylvania.The organized experience was trifactorial, with factor A-planting period, factor B-hybrid and factor C-seedling type. All factors had two graduations, thus resulted 8 experimental variants. The first planting period was the second decade of May and the second period was the third decade of June. The hybrids used were F1 Winterbor and F1 Redbor and the seedlings, one part were transplanted and the other part were not transplanted.The crops from the first planting period achieved the best results. The conducted study concluded that kale is sensitive in the immediate period after planting in terms of environmental conditions, especially regarding the humidity and temperature. Thus, in regards to the environmental conditions of the Transylvanian Plateau, optimal planting period for kale is the third decade of April.

In this paperwork it is underlined the fact that vegetables are not used only in alimentary purposes, but can also be used for decoration. So, for diversifying the area of utility for vegetables plants, the so-called "edible landscaping" system is practiced. Root vegetables can be used in the purpose of creating carpets and beds made from vegetation. The kale is used in borders, squares, flower stands and can also be combined with other ornamental plants. The vegetables that are cultivated for pods, beans and capsules can be used in decorating pergolas and towers. For creating a colorful view or a contrast of colors, it is preferred to use green vegetables. To arrange beautiful garden using ornamental vegetables some basic landscape architecture principles need to be followed and the plants that are going to be used, chosen carefully.

One of the most important aspects on mushroom culture is represented by substrate disinfection. The yield can be compromised if the competitive microorganisms are not removed from the cellulosic materials. The aim of these researches was to determine the most efficient method of disinfection. We have chosen five different methods of disinfection: material boiled for one hour, material boiled for 10 minutes, material scalded with boiled water (100 degree), material disinfected with a fungicide (Derosal 0.01%) and material soaked in water for 24 hours with no disinfection. It has been noticed that method of disinfection affects the mycelium development, date of fructification and yield. The best yields have been obtained for variants with material scalded with boiled water (100 degree), material disinfected with a fungicide (Derosal 0.01%) and material boiled for o...
