Upland Rice Growth And Yield Response To Weed Management Practices Under Rainfed Conditions

ABSTRACT

Field experiments were conducted in two seasons at Sokoine University of Agriculture farm in Morogoro, Tanzania (6.850 S; 37.640 E and 568 m.a.s.l.) during the short rain (November 2014 to January 2015) and the long rain (March to June 2015). The experiment was a split plot in a randomized complete block design (RCBD) with 4 replications. Weed management practices (pre-emergence (ULTRA 2, 4-D), postemergence (Hansunil), hoe weeding (3x) and weedy) were the main plot treatments and four rice genotypes (NERICA-1, NERICA-4, NERICA-7 and Mwangaza) were the subplots. Significant differences (P pre-emergence (3323.8kg/ha) and weedy plots (0.78kg/ha) 2015 experiment. The highest net return (3 352 846 Tshs) was obtained on NERICA-1 in post-emergence plots, this was also iii similar (P
