Agronomic Response of Pole Beans (Phaseolus vulgaris L.) to Drip Fertigation

Background: Fertigation with water soluble fertilizers, unlike traditional fertilizer application in bulk quantity in few splits, improves quality and quantity of produce in pole beans. Methods: The experiment was laid out in Randomized Block Design consisting of ten treatments and replicated thrice. The treatments consisted of different levels of nutrient doses applied at varying frequencies through fertigation using water soluble fertilizers compared with soil application of nutrients through traditional fertilizers. Result: The higher values for yield attributes viz; fresh weight of 5 pods (73.05 g), pod length (23.17 cm), pod girth (3.26 cm) and pod yield (34.67 t ha-1) were recorded with application of 100% nutrient dose through fertigation on bi-weekly basis. However, fertilizer use efficiency (179.60 kg kg-1) and benefit cost ratio (1.74) were higher with 75% of the nutrient dose of fertilizer through water soluble fertilizers at bi-weekly intervals.
