On-Farm single strip treatment trials

Abstract

The dataset comprises data collected from six unreplicated on-farm experiments (OFE) conducted in Córdoba, central Argentina. These experiments included three field trials of corn (Zea mays L.), designated as F1, F2, and F3, and three field trials of soybean (Glycine max (L.) Merr.), designated as F4, F5, and F6. Trials F1 and F6 were conducted under irrigated conditions, while the others were rainfed. In F1, the effects of a starter fertilizer on corn were assessed using two single strips: Treated, with a fertilizer application rate of 100 kg ha–1 [21-17-3 + 1% MgO + 5% S + 0.1% Zn], and Control, with no fertilizer (0 kg ha–1). Each strip was 1.1 ha in area, totaling 34 ha. In F2, the impact of broadcast phosphorus (P) fertilization was evaluated. The treatment strip received superphosphate at rates ranging from 250 to 500 kg ha–1 [0-21-0], while the control strip received no P fertilizer (0 kg ha–1). Each strip was 2.2 ha in area, totaling 100 ha. In F3, the OFE focused on the effect of foliar zinc application at the V4 growth stage. The treated strip received a dose of 2 L ha-1 (700 g L-1), while the control strip received no zinc (0 L ha-1). Each individual strip was 2 ha in area (500 m long × 40 m wide), totaling 68 ha. In F4 and F6, the effectiveness of foliar boron (B) fertilization at the R3 growth stage was evaluated. For F4, the treated strip, which covered an area of 2 ha (680 x 30 m), received 1 L ha–1 (150 g L-1), while the control strip received no boron (0 L ha–1), and was 1.8 ha in area (640 m x 30 m) on a 42-ha field. For F6, the treated strip received 2 L ha–1 (150 g L-1) and covered an area of 4.9 ha, while the control strip (0 L ha–1) covered 7.5 ha on a 59-ha field. In F5, the OFE assessed the impact of broadcast phosphorus (P) fertilization on soybean. The treated strip received triple superphosphate containing calcium at rates ranging from 250 to 500 kg ha–1 [0-46-0 + 15% Ca], while the control strip received no P fertilizer (0 kg ha–1). The plot covered 61 ha, with strip dimensions of 450 x 50 m, resulting in areas of 2.3 ha for the treatment and control.
