Resumo: | The realization of optimal recommendations for the nutrient balance of upland rice is an excellent strategy to increase the productivity and sustainability of the production system, especially in soils with limiting conditions for cultivation. The objective of the study was to evaluate the behavior of upland rice cultivars (ANa 9005CL, ANa 8001, AN Cambará and BRS A502), by foliar fertilization (MaxiZinc®, Booster® and Broadacre®) in the first year under dryland conditions in Vilhena-RO. The experimental design adopted was a randomized block design (BCT), with four cultivars and two levels of micronutrients and four repetitions, in a 4 × 2 factorial scheme. The production components evaluated showed statistically non-significant means for the foliar fertilizer factor, except for the number of spikes per panicle, for which there was a significant difference with an 8% increase in the cultivar ANA 8001 in relation to the other cultivars evaluated. Although the cultivar BRS A502 had fewer spikelets per panicle, the number of panicles per m2 compensated for this and ensured statistical equality in yield. The cultivar ANa 8001 produced the best results in terms of productivity and physical quality of the grains, under the edaphoclimatic conditions of the region. |

The experimental design adopted was a randomized block design (BCT), with four cultivars and two levels of micronutrients and four repetitions, in a 4 × 2 factorial scheme. The production components evaluated showed statistically non-significant means for the foliar fertilizer factor, except for the number of spikes per panicle, for which there was a significant difference with an 8% increase in the cultivar ANA 8001 in relation to the other cultivars evaluated. Although the cultivar BRS A502 had fewer spikelets per panicle, the number of panicles per m2 compensated for this and ensured statistical equality in yield. The cultivar ANa 8001 produced the best results in terms of productivity and physical quality of the grains, under the edaphoclimatic conditions of the region. |
