Flowering Behaviour and Seed Yield of French Bean as Affected by Variety

Abstract

The effect of flowering pattern and floral abscission on the yield and yield attributed characters of French bean varieties were studied in a field of Bangladesh Agricultural Research Institute, Gazipur. There nine varieties were treated- (1) BARI Jharsheem-1 (2) BARI Jharsheem-2 (3) Sylhet local-1 (4) Sylhet local-2 (5) Sylhet local-3 (6) Sylhet local-4 (7) Sylhet local-5 (8) Sylhet local-6 and (9) Sylhet local-7. Among the treatments, the highest number of flower was recorded within 5 to 8 days in BARI Jharsheem-2 although, the maximum flower opened within 5 to 8 days and following ceased within 15 to 20 days after first flowering. The total number of flowers per plant varied between 19.36 to 45.06 and 22.0 to 47.20 in two consecutive years while percentage of pod abscission varied between 70.53 to 82.26 and 73.46 to 80.75 in two consecutive years. The maximum yield of French bean was obtained from BARI Jharsheem-1, however identical yield was obtained from BARI Jharsheem-2 treatment. The flowering pattern and percent abscission as well greater number of pod were found to be the influential character for the highest yield of French bean. In addition, seed yield was strongly correlated to the number of opened flowers as well as number of mature pods. Int J Appl Sci Biotechnol, Vol 3(3): 483-489

Growth and Yield Comparison of French Bean as Influenced by Three Varieties and Nutrients

“…[16] reported that days required to first flowering showed little differences among the various cultivars of French bean. The result is similar to the findings of [17]. The data on days required to first flowering was found to be significant in terms of different levels of nutrients on French bean (…”

“…The number of flowers per plant of French bean was significantly influenced by the three varieties [17] observed that BARI French bean-2 produced the highest number of flowers per plant while BARI French bean-1 produced the lowest number. The number of flowers per plant showed significant differences due to the application of different levels of nutrients flowers per plant (32.02) was recorded from the treatment combination of V 2 N 2 (BARI French bean-2 and cowdung @ 5 t/ha + N 90 P 30 K 45 kg/ha) while the minimum number of flower per plant (13.33) was recorded from a combination treatment of V 3 N 1 (BARI French bean-3 and cowdung @ 5 t/ha + vermicompost @ 2 t/ha) .…”

Response of BARI Bush Bean-2 at Different Levels of Nitrogen Fertilization

“…Fresh green beans are sweeter than canned. This crop is also valuable in Bangladesh mostly for exporting tender beans to the European market [11]. In recent years, the Hortex Foundation, Vegetable Export Center of BRAC and some other organizations facilitated the export of this vegetable of Bangladesh.…”

Effect of Different Levels of Potassium Fertilizer on the Yield Components of BARI Bush Bean-2

“…Additionally, the crop has a well-known export quality which has attracted the attention of the Agriculture industry and exporters [3]. This crop is also valuable in Bangladesh mostly for exporting tender beans to the European market [10]. In this context, the yield of Bush bean has become an important component of vegetable production and cash income.…”
