Abstract/Description: | Azolla intercropped with rice transplanted in a rectangular (10× 40 cm) spacing produced greater biomass and accumulated more N than with rice in a square (20× 20 cm) spacing. The differences in biomass and N accumulation were greater in the 2nd crop of Azolla at 50 d after transplanting (DAT) of the rice crop than in the 1st crop of Azolla at 30 DAT. Azolla produced greater biomass and fixed more N with rice rows in the rectangular spacing in an EW direction than with rice rows running NS. Growing and incorporating Azolla once before transplanting and twice after transplanting produced the highest grain and straw yields, number and wt of panicles, and N uptake by rice. Azolla application also significantly increased soil total N, organic C and available P contents. |
