- Abstract
A field experiment on the effect of different type of treated wastewater with variable doses of fertilizer in fodder maize was carried out during summer 2021 at agroforestry unit, GKVK, Bengaluru, consisting of twelve treatments replicated thrice, assigning three sources of irrigation (Borewell water, secondary and tertiary treated wastewater) as the main plot treatment with four subplots of variable doses of fertilizer (0, 25, 50 and 100% of RDF) was laid out in a split-plot design. The results revealed that irrigation by secondary treated wastewater with 100 per cent RDF application recorded significantly higher plant height (255.7 cm), leaf area (5961 cm² plant-1), SPAD reading (42.13), green seeker values (0.72), stem girth (19.36 mm) and green fodder yield (623.1 q ha-1) at harvest as compared to borewell water irrigation with 100 per cent RDF (240.6 cm, 5432 cm² plant-1, 39.80, 0.71, 18.22 mm and 573.3 q ha-1, respectively) and was on par with tertiary treated wastewater irrigation along with 100 per cent RDF application (249.6 cm, 5831 cm² plant-1, 39.98, 0.72, 19.07 mm, 605.0 q ha-1, respectively). Irrigation with borewell water without fertilizer application recorded significantly lower plant height (153.3 cm), leaf area (2553 cm² plant-1) and green fodder yield (320.9 q ha-1) as compared to other treatments. The higher growth and yield in treated wastewater irrigation were primarily attributed to higher nutrient content as compared to borewell water irrigation.
