EVALUATION OF DIFFERENT PLANTING SPACINGS IN CASSAVA CROP AND ITS RELATIONSHIPS WITH WEED INCIDENCE AND PRODUCTIVITY

| Sumario: | One of the main factors for low productivity, as well as for the increase in production cost in cassava crops, is related to inadequate weed control. This study analyzed different planting spacings using two cassava cultivars: “Arapiraca” and “Saracura”, in the municipality of Itapicuru, State of Bahia, in order to perform the cultural control of weeds, as well as to evaluate the productivity of both cultivars. The experimental area was set up as follows: C 01 (“Arapiraca”) and C 02 (“Saracura”), and four planting spacings E 01 (1.0 m X 1.0 m); E 02 (1.0 m X 0.8 m); E 03 (1.0 m X 0.6 m) and E 04 (1.0 m X 0.5 m), in a 2 x 4 factorial scheme, totaling 8 treatments, adopting a randomized block design, with 3 replicates. Treatments were as follows: T1: C01E01; T2: C01E02; T3: C01E03; T4: C01E04; T5: C02E01; T6: C02E02; T7: C02E03; T8: C02E04. Periodic observations of weed incidence in all treatments and the crop behavior as a function of these planting spacings were performed. The average root production and the average commercial root production per plant occurred in treatments T1 and T2; however, the highest total root yields occurred in planting spacings T3 and T4, due to the greater number of plants per area. Therefore, it could be concluded that, for the production of table cassava, even requiring a third weeding, less dense planting spacings are the most suitable, due to their better quality, as well as the greater amount of roots produced; however, for root production destined for industry, denser planting spacings are recommended, as greater productivity is achieved, in addition to better control of the negative effects of weed infestations, reducing production costs. |
