Opis:: An attempt has been made in this paper to analyse the spatio-temporal variations of cropping intensity and irrigation intensity, and their relationship, in North Twenty Four Parganas district in West Bengal, India from 1996/97 to 2015/16. The relationship between cropping intensity and irrigation intensity has been assessed using partial correlation, residual mapping and hierarchical cluster analysis. One-way ANOVA has been conducted for testing the equality of cluster means. Temporal analysis from 1996/97 to 2015/16 has shown a low positive correlation between cropping intensity and irrigation intensity for the entire district. Analysis at Agricultural Block level has revealed that cropping intensity decreased in many cases even after an increase in irrigation intensity. In general, cropping intensity has increased with the increase in irrigation intensity in the Coastal Saline Region and the Ichhamati Basin, whereas cropping intensity has increased even after a decrease in irrigation intensity in the Gangetic Plains Region in the district.

Opis:: The study was conducted in 2001–2012 next to Wrocław (south-western Poland). The purpose of this research was to assess the influence of type of nursery trees of pear cvs ‘Carola’ and ‘Dicolor’ budded on quince S1 rootstock on growth and cropping, as well as fruit quality of two pear cultivars. The trees were planted in the spring of 2001 in 4 replications with 5 trees per plot. Trees were planted in rows with spacing 1.2 × 3.5 m (2381 trees per hectare). Three types of nursery trees, all without feathers, were planted: twoyear-old (3 years in a nursery), one-year-old maidens (2 years in a nursery) and annual grafts (only 1 year in a nursery). Tree canopies were formed as a spindle and were trained in the Güttingen-V system. Until the twelfth year after planting, growth and yield were significantly affected by the type of nursery trees. One-year-old maidens were characterized by the strongest vigor in orchard, while pears planted as twoyear-old trees grew rather weak (especially with ‘Dicolor’ cv.). Planting two-year-old trees didn’t have any clear positive influence on tree cropping in the orchard. The final results of the study proved that trees planted as annual grafts, irrespective of cultivar, yielded significantly worse. The type of nursery trees had no clear influence on mean fruit weight.
