Effect of different dripper discharge, spacing and lateral spacing on drip irri-gated green bean yield and quality parameters

Abstract


Experiments were conducted to assess the effects of different dripper discharges, dripper spacings and lateral spacings on yield and physical quality attributes of drip-irrigated green beans. Three different drip irrigation system were arranges as: DS1: dripper discharge is 2 L h‒1, dripper spacings is 33 cm and lateral spacings is 50 cm (a lateral line for each plant row); DS2: dripper discharge is 2 L h‒1, dripper spacings is 33 cm and lateral spacings is 100 cm (a lateral line for two plant rows); DS3: dripper discharge is 4 L h‒1, dripper spacings is 50 cm and lateral spacings is 100 cm (a lateral line for two plant rows). In irrigations, wetted area percentage was taken as 75%. Present findings revealed that different drip irrigation treatments did not have significant effects on yield and physical quality attributes of green beans. Therefore, it was concluded that lateral spacing in drip irrigation of greenbeans could be selected as 100 cm (a lateral line for two plant rows). This will bring at least 50% saving in lateral pipe costs of drip irrigation systems.
