Abstract

The objective of this study was to obtain relationships between plant LEAF AREA (cm2 plan-1) with main stem node number, leaf DRY WEIGHT (g plant -1), vegetative DRY WEIGHT (g plant -1) and PLANT HEIGHT (cm). An experimental design was conducted in the field at Agricultural Science Research Farm of the Gorgan University. Experimental design was a factorial arrangement of treatments based on randomized complete block design with four replications. The treatments were combinations of three sowing dates and four plant densities. Sowing dates were 6 Dec. 2003, 20 Jan. 2004 and 21 Mar. 2004. Plant densities were 15, 30, 45 and 60 plants m-2, Sampling was carried out to first pod (50% of plants with 0.5 cm pod at one of the 4 upper nodes with unfolded leaf, R3). At each sampling LEAF AREA, main stem node number, leaf DRY WEIGHT, vegetative DRY WEIGHT and PLANT HEIGHTs were measured. The power equation in linear form {ln(y) = ln (a)+bxln (x)} was used to describe the relationship between LEAF AREA and the mentioned characteristics. This equation was used for all combinations of sowing dates and planting densities. Significant relations were found between LEAF AREA and main stem node number (R2=0.94), leaf DRY WEIGHT (R2=0.94), vegetative DRY WEIGHT (R2=0.93) and PLANT HEIGHT (R2=0.83). It was concluded that the equations could be used for estimation of LEAF AREA or can be used in crop simulation models of CHICKPEA.
