We studied the effect of four methods and two frequencies of irrigation on yieId components; in addition we determined the effect on the salt concentration of the soil solution and its relationship with these factors.
The treatments corresponding to furrow method on every row, furrow methods on alternate rows, furrow rnethod on off-set rows and furrow method every two rows. The frequencies of irrigation were 0.4 and 0.75 atm. The yield components were number of pods per· plant, numbers of seed per pod, and seed weight. Correlation coefficients and regression equations were used to relate with dry matter, vegetative period, yield, and electrical conductivity of soil solution.
Methods and frequencies of irrigation had no effects on number of pods per plant and number of seed per podo The seed weight increased significantly with the 0.4 atm frequency.
The yield components were affected significantly but in different magnitude by the vegetative periodo The number of pods per plant was affected by the soil salt contento It was determined that yield is correlated with seed weight and number of pods per planto
