Abstract

A field experiment was conducted at National Rice and Bean Research Center, EMBRAPA, Goiânia, to study the effects of different technologies used by farmers as compared with that recommended by research on growth, yield and pattern of nutrients uptake of upland rice (Oryza sativa L.). Relative growth rate and relative plant height reduced with advancing age of the plant in both technology levels tested. Accumulation of P, K, Ca, Mg and Zn increased with increasing plant age. Application of fertilizer based on soil analysis increased yield significantly. Similar effect was obtained with respect to weed control with two hand weedings.
