Yield of peas under short-term crop rotation depending on the intensity of natural moistening of podzolized chernozem
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 100, Issue 2
Abstract
The results of the research on the yield of peas in short-term crop rotations after various predecessors during a long period of time are given in order to establish certain relationships between the weather and the crop harvest. It has been established that peas, like any other culture, strongly responds to the weather and climatic conditions. During the years characterized by optimal humidity, the productivity level reaches up to 31.9 dt/ha, and when the amount of precipitation decreases to normal, the yield level in most years varies from 21.3 to 26.8 dt/ha, depending on predecessors. Under significant deterioration of the natural moistening conditions the yield of legume crops reduced to 12.1–15.6 dt/ha, and under especially critical conditions, as it was in 2007, peas may not produce a grain yield at all. Sugar beet and corn are the best predecessors for peas and only in some years it may be spring barley. Failure to meet the term date of peas cultivation return to the previous place leads to a reduction in the yield of leguminous crops despite the condition of natural moistening of chernozem soil.
