Growth and yield on four varieties of corn on different ameliorant combination and application system under culture of saturated soil on tidal swamp

Abstract

There was research at Karya Bhakti Village. Rantau Rasau Sub District. Tanjung Jabung Timur District. Jambi Province from March until July 2022. This research used a randomized complete block design with three factors and three replications. The factor I is variety consisted of 1) Pioneer-27. 2) Bisi-18. 3) Bima-20-URI. and 4) NK-Sumo. Factor II is an ameliorant combination consisting of 1) without ameliorant. 2) oil palm empty fruit bunches compost. 3) oil palm empty fruit bunches compost + cow dung fertilizer. 4) oil palm empty fruit bunches compost + cow dung fertilizer + dolomite). 5) Compost from oil palm fruit bunches that have been removed, cow manure fertilizer, dolomite, and rice husk ash. The application system for factor III consists of 1) disseminating to the bed surface. and 2) seed cover in the planting hole. The research result has shown that the ameliorant application did not affect the growth of corn. The corn grown in the complete ameliorant was better than without the ameliorant. The interaction between ameliorant combinations. ameliorant application . And variety affected on seed dry weight cob-1. The highest yield of corn was obtained on NK-Sumo and Bima-20-URI in the complete ameliorant with seed cover application.
