| Popis: | Fertilizer placement was studied in an extensive series of experiments on sweet corn (Zea mays L.), snapbeans (Phaseolus vulgaris L.), tomatoes (Lycopersicon esculentum Mill) and cabbage (Brassica oleracea L., Capitata group), each at 4–9 production sites in Pennsylvania during 1981–3. Treatments were 1 increment banded or broadcast, 2 increments banded, broadcast, banded/ broadcast or banded/sidedressed, 4 increments broadcast, and a check. Fertilizer increments applied were NP, each at 28 kg/ha (sweet corn and snapbeans) or NPK, each at 56 kg/ha (transplants of tomato and cabbage) as urea, triple superphosphate and muriate of potash. Banding involved a single band 5 cm to the side of seed and 5 cm deep (sweet corn and snapbeans) or double bands 10 cm to each side of plants and 10 cm deep (tomatoes and cabbage). Yields were similar when single increments were banded or broadcast except with cabbage where banded yielded higher. With double increments, banding or combinations involving banding yie... |
