This study is the first Polish agrotechnical instruction concerning the white mulberry since the 1980s. The article presents methods of vegetative and generative reproduction, soil and climatic requirements of mulberry, as well as agrotechnical treatment that limit financial and time expenditure in biomass production while obtaining a high yield of good quality biomass. Many years of experimental work enabled the development of a method of fast utilization of cut mulberry shoots through the use of agricultural machinery and revised the use of mineral fertilizers.

The aim of the study was to present: a) the distribution, properties and role of legumes in agriculture, b) changes in crop area, harvest and yields of leguminous plants in the years 1949-2013, c) self-sufficiency of legume seeds in the years 2001/02-2013/14. Development is based on research literature of the topic both compact and continuous and statistical materials of GUS using the comparative method in the form of vertical and balance sheet and statistics. Despite many advantages of legumes they are grown in small quantities, although the first years of the second decade of the twenty-first century are characterized by the growth of their crops. One reason for the small amount of cultivation of legumes are low yields and little progress in changing them. It was found changing trends in the cultivation, harvesting and crop of legumes. In the years 1950-1955 and 2006-2010 yields of edible seeds of legumes increased from 9.9 dt / ha to 19.7 dt/ha, i.e. by 98.0%, while the fodder from 9.2 to 20.8 dt/ ha, i.e. by 126.1%. Pulses are the subject of trade with foreign countries, and despite the low turnover Poland has a negative trage balance.
