Quality Parameters of Snap Bean Plant as affected by Compost Town Refuse, K-Levels and Bacillus cerculans

A field experiment was conducted in 1996 and 1997 to determine snap bean tolerance to halosulfuron based on crop injury, height, and yield. Halosulfuron was applied preemergence (PRE), postemergence (POST), and sequentially PRE followed by (fb) POST at 35, 53, and 70 g ai/ha, respectively. For comparison, a hand-weeded check was included. When data were averaged across years and halosulfuron rates, halosulfuron PRE, POST, and PRE fb POST provided similar yellow nutsedge control (74 to 82%) at snap bean harvest. Halosulfuron PRE resulted in 4% snap bean injury at harvest. Similarly, halosulfuron PRE fb POST resulted in 5% injury, while halosulfuron POST caused the most damage at 8%. Snap bean height at harvest was reduced 14% with halosulfuron POST compared to the weed-free check, with only 5 and 6% reduction caused by halosulfuron PRE and PRE fb POST, respectively. Halosulfuron POST reduced yield 39% compared to the weed-free check, while the PRE and PRE fb POST application timings produced yield similar to the check. When averaged across years and halosulfuron application timings, an increase in halosulfuron rate had no effect on yellow nutsedge control or snap bean yield. A linear trend was found for snap bean injury and plant height at harvest with snap bean injury increasing with an increase in halosulfuron rate while snap bean plant height decreased with an increase in halosulfuron rate. Application of halosulfuron PRE is the safest means to control yellow nutsedge in snap bean in North Carolina.

Snap bean is a warm-season crop harvested for its immature seed pods. In Ethiopia its production increased from time to time for both export and local markets. A field experiment was conducted at the research field of JUCAVM, during 2017 cropping season using irrigation aiming to improve the quality of snap bean. Five levels of N (0, 41, 82, 123, and 164 kg ha−1) and four levels of P (0, 46, 92 and 138 kg ha−1) were laid down in a randomized complete block design with three replications. N was applied in two equal splits (50% at planting and 50% during flowering) as Urea and the entire dose of P was applied basal as triple super phosphate at sowing. In this experiment pod length, pod diameter, pod protein concentration, pod straightness and marketable pod yield were measured as quality parameters. The results revealed that the main effects of N and P fertilizer rates showed significant differences (P ≤ 0.05) for all quality parameters except for percentage of pod protein concentration and straightness of pod. Accordingly, the interaction effects of N and P were significant for percent of pod protein concentration and straightness of pod. Considering the major quality parameters and marketable pod yield applying 82 kg N ha −1 and 46 kg P2O5 ha−1 gave better result to increase the quality of snap bean in Jimma area. However, repeating the experiment for more seasons and similar location would help us draw sound conclusion and recommendations.
