Abstract
ABSTRACT
A field trial entitled “Effect of foliar application of seaweed extract on the growth and yield of yard-long bean (Vigna unguiculata subsp. sesquipedalis)” was carried out at experimental field of Agricultural Research Station, Harichand Charsadda during spring 2022. The experiment was organized in Randomized Complete Block Design with factorial arrangements having three replications. Two factors were studied in the trail, varieties of yard long bean (Charsadda Bean and Local White), and levels of seaweed extract (control, 3 ml L-1, 6 ml L-1 and 9 ml L-1). The varieties of yard-long bean received three rounds of foliar spray, each application occurring at 10-day intervals after seedling emergence. The results showed that growth and yield of yard-long bean was significantly affected by varieties and foliar application of seaweed extract, while their interaction was not significant. In case of varieties, Charsadda Bean showed maximum vine length (376.02 cm), number of leaves per plant (112.17), number of branches per plant (13.72), pods per plant (52.37), pod length (53.56 cm), pod diameter (7.84 cm), seeds per pod (16.025), number of pickings (9.92), pod yield per plant (1.33 kg), pod yield (43.567 tons ha−1) seed yield (785.69 kg ha−1) and minimal days to first picking (57.75) as compared to Local White. Data concerning the application of seaweed extract divulged that maximal vine length (386.41 cm), number of branches per plant (14.67), number of leaves per plant (119.89), pods per plant (45.52), pod length (50.82 cm), pod diameter (8.21cm), seeds per pod (15.81), number of pickings (10.50), pod yield per plant (1.34 kg), pod yield (44.03 tons ha-1), seed yield (738.71 kg ha−1) and minimum days to first picking (57.33) were recorded when yard-long bean plants were treated with 9 ml L-1 of seaweed extract. Most of the parameters at 9 ml L-1 were statistical similar to those noted at 6 ml L-1of seaweed extract. Based on the results, it is concluded that the Charsadda Bean variety of yard long bean and a foliar application of seaweed extract at a concentration of 6 ml L-1, showed greater significance across all growth and yield parameters compared to the Local White variety and other seaweed extract levels. These findings are applicable to the agro-climatic conditions of Harichand, Charsadda and similar areas with the same agro-climatic conditions.
