Improving the Growth and Productivity of Two Varieties of Mung Bean (Vigna radiata L.) by using Different Cultivation Methods and Dates

Abstract

Background: Mung bean is characterized by its ability to withstand water scarcity due to its short life span, so it can be introduced into agricultural rotation systems and despite especially when there is a lack of humidity and contemporary environmental changes. Despite the importance of this crop, its productivity rate in Iraq is still low compared to global production. The dates and methods of cultivation of the mungbean crop must be determined accurately to suit the specifications of local varieties adapted to the changing environmental conditions. Methods: The field study was applied in two fields: the first in Nineveh Governorate and the second in Erbil Governorate / Republic of Iraq. Three factors included, first: two varieties of local mung bean (black and green), second: different cultivation methods (furrow and lines) and the third: planting dates (May 15, June 15 and July 15). The study was designed as a factor experiment a design (R.C.B.D) with three replicates. Result: The first variety superior significantly in the two sites with the qualities of (plant height, leaf area, leaf area index, seed yield, Biological yield and harvest index. From the results of the dates, we note a significant superiority of the first date number of seeds.pod-1 while the third date significantly outperformed the germination percentage for the two sites. First planting method significant superiority in most of the studied characterists and for the two research sites. Significant superiority was recorded for the interactions of research factors and their levels.
