To examine the effects of plant density and weed control methods on vegetative and reproductive characteristics and yield of kidney beans, the Research Center of Agriculture in Khoy –W. Azarbaijan conducted a factorial experiment in the form of randomized complete block design (RCBD) with three replications from 2018 to 2019. In this study plant density at three levels of 20, 25 and 30 plants per square meter, and weed control methods at four levels of non-control, selective herbicide (bentazon ), manual control and application of general herbicide (paraquat) were chosen. The results showed that there was a significant relationship between plant density and weed control methods and lateral branches, number of pods per plant , grain yield, biological yield and protein yield; however there was no meaningful relationship between plant density and weed control methods and other characteristics such as plant height and the percentage of grain protein. The highest grain and biological yield were obtained at a planting density of 30 plants per square meter and manual weeding; afterwards, the manual weeding was followed at 3391 and 15275 kg/ha respectively and the highest percentage of grain protein at a density of 20 plants per square meter together with manual weeding was obtained at the level up to 24.8 %. The results also indicated that the manual control method was relatively effective and proved to be better than all other methods, with the consequence that herbicides by themselves were not effective in controlling weeds of kidney beans. Production of grain yield with a maximum density of 30 plants per square meter indicated that a positive response of kidney beans to the high density of the plants. Manuscript profile
