Abstract In Europe, Spain is the
principal chickpea
(Cicer
arietinum) producer. Traditionally, the chickpea crop is
predominately
a spring crop and is rain-fed. However, a little of the crop is
irrigated. The sowing density used depends principally on soil water
availability. This work was carried out in 2001 and 2002 in the
province of León, Spain, under irrigated conditions to
determine the influence of sowing densities of 8, 16, 25, and 36
plants/m2 on the yield and yield components of a kabuli type of
chickpea. There was a reduction in the number of pods/plant (mean, from
56.0 at 8 plants/m2 to 14.3 at 36 plants/m2) and the 1000-seed weight
(mean, from 406 g at 8 plants/m2 to 383 g at 36 plants/m2) as plant
density was increased. The highest yields of 222 and 208 g/m2 were
obtained at the highest density (36 plants/m2) and the lowest density
(8 plants/m2), respectively. With the exception of 8 plants/m2,
increases in yield were caused by an increase in plant density.
