Acids which are selected for the study were DS-99, Nitric acid, sulfuric acid, Hydrochloric acid and phosphoric acid. No acid treatment was taken as a control. For selected two polyhouse total twelve treatments (six treatments for online type emitter and six treatments for inline type emitter) were given. Further it was also planned to inject the acid at fixed interval (15 days).The biometric observations of plants such as plant height (cm) and girth (cm) of these plants were noted periodically to see the effects of unclog emitters discharge due to application of different acids treatment.
