Title
Optimum Spacing of Preplant Bands of N and P Fertilizer for Winter Wheat1
T. M. Maxwell; D. E. Kissel; M. G. Wagger; et al. Agronomy Journal 1984. doi:10.2134/agronj1984.00021962007600020017x
Other claims from this paper (10)
- Intervention effect Early season growth of winter wheat increased with increasing P rate.
- Intervention effect Early season growth of winter wheat increased with decreasing distance between preplant bands.
- Intervention effect P rate influenced final grain yield of winter wheat.
- Association Phosphorus uptake from the fertilizer band was influenced by the lateral distance from the wheat row to the P band at 33 days after planting.
- Intervention effect Fertilizer P uptake was the same from bands placed 0, 10 and 20 cm from the wheat row at 40 days after planting.
- Intervention effect P uptake was significantly less from the band placed 30 cm from the wheat row than from closer bands at 40 days after planting.
- Mechanism Lower P uptake from the 30 cm band is apparently due to another wheat row shielding the fertilizer P.
- Association Samples over and between bands differed in dry matter production, P uptake and spike density due to P rate and band spacing.
- Intervention effect More uniform growth resulted from the closer band spacing of 38 and 25 cm.
- Intervention effect The closer band spacing of 38 and 25 cm could result in higher grain yields under optimum production conditions.
