Abstract:

A study was conducted in the Instructional Farm of PFDC, Tavanur, Kerala, during the period from November 2018 to February 2019 to Standardization of irrigation and fertigation requirement for amaranthus under polyhouse. Amaranthus variety CO1 was used for the study. Fertilizers were applied through drip irrigation system using venturi assembly. There were three levels of irrigations i.e., I1-100% of ETc (crop evapotranspiration), I2-80% of ETc and I3-60% of ETc and three levels of fertigation viz: F1-100% of Recommended Dose of Fertilizer (RDF), F2-125% of RDF and F3-150% of RDF. Crop parameters such as plant height, number of leaves and yield were noted during various crop growth stages for all the treatments. The treatment I2F3 (Irrigation 80% of ETc and Fertigation 150% of RDF) showed comparatively better performance in yield characteristics as compared to the other treatments.
