Overview
- This week the Bolsa de Comercio de Rosario issued a first estimate of 23.8 million tonnes for the 2026/27 wheat crop and a national average yield of 35.3 qq/ha, placing the harvest as the second‑largest in the last 17 years.
- Persistent cloudiness and below‑normal temperatures have reduced solar radiation during the crop’s critical grain‑fill window and agronomic frosts on Oct. 18–19 have added material uncertainty about final yield and grain set.
- Regional and technical bulletins report early, localized losses of roughly 10–15% in some early‑seeded and short‑cycle lots in southern Santa Fe, Entre Ríos, Buenos Aires and La Pampa, though widespread damage has not been confirmed.
- The adverse October pattern is already affecting summer crops and field work, with maize sowing about 39.8% complete and emergence problems and delayed soybean planting reported in several zones.
- Final outcomes remain weather‑dependent: analysts point to the cociente fototermal (radiation relative to temperature) and disease pressure as key determinants, and any change in late‑October/November conditions will decide how much of the projected potential is realized.
