Production potensial of sweet corn (Zea mays Linn. var. Saccharata Sturt ) 'Bonanza' to different planting pattern and phosphorus sources

Abstract

Planting pattern factors that regulate population density of plant greatly determine optimal plant growth and production. The "Jajar legowo" system adopted from rice plants was applied to corn plants to obtain the effect of marginal plants. The study wanted to know sweet corn ((Zea mays Linn. var. Saccharata Sturt) 'Bonanza' production based on planting patterns on various phosphorus sources. The study used factorial experiments which were arranged based on a randomized block design which was repeated three times with the planting pattern factor including conventional planting 70 cm × 20 cm, jajar legowo (2:1) with 20 cm × 50 cm × 100 cm and dense planting 105 cm × 12.5 cm. Source factor P consists of SP-36, mycorrhiza plus, and biofertilizer. The results showed that there was a significant interaction effect between the planting pattern and source of P on the dry weight of the plant, mostly in the combination treatment of the conventional system with SP 36 was 123.51 g. The weight cobs and corn cobs with cornhusk have the highest weight on the dense planting pattern which is no different significantly from conventional planting pattern.
