Effect of drip-fertigated and soil-drenched liquid organic manures on growth and yield of maize intercropped with vegetable amaranth

Afield experiment was carried out at the Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu to assess the effect of irrigation methods on growth and yield of maize in comparison to drip irrigation and surface irrigation systems during 2016–17. The treatment comprised two irrigation methods with seven fertilization methods viz humic acid 3 kg/ha, fulvic acid 3 kg/ha, vermiwash 5 per cent, Jeevamiritham 5 per cent and their combinations and inorganic fertilizers were the fertilization treatments. The drip irrigation showed superiority in growth characters and yield of the crop. Among fertilization methods inorganic fertilizers registered significant influence on the crop yield ie 7298 and 7384 kggrainyield/ha thatwas comparable with humic acid 3kg/ha+ fulvic acid 3kg/ha treatment ie 6250 and 6184 kg/ha during first and second year respectively. In case of amaranth higher fresh green yield was due to the inorganic fertilizer application treatment followed by Jeevamiritham.
