THE EFFECT OF PHOSPHORUS ON YIELD AND YIELD COMPONENTS OF GREEN BEAN (Pages : 9 - 13)

An experiment was carried out in Shaft, north of Iran, in 2013 to study the effects of phosphorus fertilizer on yield and yield components of green bean (Sunray genotype). The experiment was laid out in a randomized complete block design with three replications. The rate of phosphorus fertilizer was 0, 20, 50, 75 and 100 kg ha-1. Analysis of variance indicated that phosphorus fertilizer had a significant effect on plant height, pod length, number of pods per plant, green pod yield, biological yield and harvest index. Correlation analysis indicated pod yield positively correlated with plant height, number of pods per plant and harvest index. The result of regression analysis indicated that there was a significant positive and quadratic relationship between P application and pod yield. Application of 50 kg P ha¬-1 lead to maximum values of plant height, pod length, number of pods per plant and pod yield. Phosphorus fertilizers increased also dry matter accumulation. Phosphorus supply beyond 50 kg P ha-1 generally resulted in decline of pod yield and yield components. Thus, application of 50 kg P ha-1 is recommended for better production of green bean at Guilan province, Iran. Download
