Abstract :

An experiment was carried out to determine the effcet of climatic parameters on the yield of three pear tree varieties: Wiliams Bartlett, Clapp's Favorite and Conference in 1987-01 in Pozorty near Olsztyn (Poland). It have been found that the climatic conditions during the vegetation period have a significant effect on the yield. The effect of the analysed climatic factors depended on the vari ...

Abstract :

The studies on the weight of after-harvest remains were carried out on permanent and alternate meadows in 2000. Twenty samples were taken from every three objects up to 150 mm depth. Studies revealed that 12.84 - 21.55 t dry matter of after-harvest remains are left per one hectare of grasslands. About 50 percent of grass roots reached only 5 cm depth and the stubble was 30-40 percent of the to ...

Abstract :

It was found that low in erucic acid variety of winter rape produced about 15% less of nectar in comparison with standard varieties. They produced pollen as high erucic acid varieties of rape and they were also extensively visited by pollinating insects, among whose almost 98% were honey bees. Besides that low in erucic acid varieties of rape especially Quints and Primor were almost equal in y ...

Abstract :

It was found that one flower of tetraploid buckwheat cultivar Emka secreted 30 per cent more nectar and produced 38 per cent more pollen than one flower the standard diploid cv. of Hruszowska. This cultivar also yielded 16 per cent more sugar from 1 ha and 20 per cent more pollen. When the plants were protected from insect pollination, cv. Emka yielded 50 per cent and cv. Hruszowska 65 per cent.

Abstract :

The nectar secretion was investigated on gooseberry White Triumph, Lady Delamere, Resistenta and Shanon cvs. The highest quantity of sugar was produced by flowers of White Triumph (1.5 mg/24 h), the lowest by Lady Delamere cv. It was discovered that Shanon cv. reached the highest honey productivity, whereas Lady Delamere cv. the lowest. The pollen mass produced by one flower of White Triumph r ...

Abstract :

The differences in the flowering course, intensity of nectar secretion, amount of pollen and productivity between the studied cultivars were stated. The mean yield of the honey from 1 ha of raspberry plantations varied from 115 to 240 kg. The yield of pollen of the studied plantation was 3-13 kg from one ha. The flowers of cultivars Norna, Canby and Malling Seedling were visited by honey bees ...

Abstract :

Investigations were carried out on influence of pollinating insects on yielding of 6 varietes of strawberry and estimation of nectar secretion and production of pollen. For proper pollination of 1 ha plantation of strawberries, 1-2 bee colonies of medium strength are needed. The highest crop of strawberries from 1 ha was produced by Senga Sengana, next Kola-82, Surpise des Halles, Felina, Redg ...
