Hf. Schnier et al., YIELD RESPONSE OF WETLAND RICE TO BAND PLACEMENT OF UREA SOLUTION IN VARIOUS SOILS IN THE TROPICS, Fertilizer research, 36(3), 1993, pp. 221-227
Alternative N-fertilizer management practices are needed to increase p
roductivity and the N-use efficiency of flooded rice (Oryza sativa L.)
. Seven field experiments were conducted at various sites in Banglades
h and Indonesia to evaluate the effect of time and method of fertilize
r-N application on grain yield in transplanted rice. Conventional fert
ilizer application was compared with band placement of liquid urea usi
ng a mechanical push-type injector and point placement of urea supergr
anules. With band placement, grain yields were up to 38 and 55% higher
than with researchers' and farmers' practices, respectively, and simi
lar to those with point placement of urea supergranules.
