The effect of row and planting spacing on yeild in the white bean cv. Danshkadeh

In order to study the effects of row and plant spacing on the grain yield of withe bean, cv. Daneshkadeh, a field experiment was camied-out in Khomein field Research station in 2002 cropping season. Four levels of row spacing, 30, 40, 50 and 60 cm and three levels of plant spacing on row, 5, 10 and 15 cm were studied in split plot arrangement using randomized complete block design with four replications. Four levels of row spacing were assigned to main plots and three levels of plant spacing to sub plots. The results showed that increasing row spacing and plant spacing, i. e. decreasing plant density, the grain yield significantly decreased. The highest grain yield (2605 kg/ha) was obtained from the combination of 30 * 5 cm, row and plant spacing, respectively.
