Haricot Bean (Phaseolus vulgaris L.) Varieties Growth Analysis at Hawassa University, Ethiopia

Shimelis Mohammed


A field experiment was conducted with haricot bean varieties and were planted for growth analysis in 2018 before cropping season at Hawassa University, It geographically  located at 0703'N and 38028'E, and at 1708 masl. Maximum and minimum daily temperature was 27 and 13oc respectively. This experiment used RCB design with 4 replications and 3 Haricot bean varieties Ibado, Omo-95 and Red Wolayita. The plot area was 2m×2 m and was planted with 5 rows. The primary data for growth analysis were collected twice; such as leaf area, stem weight, leaf weight and total weight.  SLA, LAR, NAR and RGR were analyzed. Ibado and Omo-95 varieties are the highest and least in leaf area ratio accounts 200.98 (cm2g-1), 171.57 (cm2g-1) respectively at 1st sampling but at second sampling Ibado becomes the least, Red Wolayita scores higher in leaf area ratio 162.17(cm2g-1). On the other hand from first sampling Ibado take the pick position in specific leaf area 312.46 (cm2g-1) and the least was Red Wolayita. But from second sampling Omo- 95 takes the higher position with 340.65(cm2g-1) and Ibado was the least with 300.85(cm2g-1) in specific leaf area. Red Wolayita relatively grows higher 72.81 (mgg-1day-1) than Omo-95 and Ibado varieties. And also by their net assimilation rate (NAR) go similarly like that of relative growth rate (RGR) Red Wolayita  43.55(mgdm-2day-1) was higher in sink from sources. All tested parameters from ANOVA tables are not significantly different.
