| dc.description.abstract | Field experiments were conducted to study the effect of fertilizer nitrogen and azolla on yield of rice in Tamil Nadu Agricultural University wetland farm, Coimbatore. Experiments were laid out in a randomised block design with four replications during kharif and rabi, 1984-85. Azolla as dual crop, green manure, different forms of urea like prilled urea (PU), urea super-granules (USG) and neem coated urea (NCU) and their combinations were tried. Azolla biomass production was more in rabi season than kharif. All the forms of urea applied at 75 kg N/ha with and without azolla produced more yield than the control. Plots treated with 25 kg N each as PU, USG and NCU besides azolla as dual crop in kharif and 75 kg N as NCU and azolla as dual crop in rabi recorded the highest grain yield. Dry matter production had the maximum direct effect on grain yield in both the seasons. | en_US |
