Abstract

 

Coastal land is a suboptimal land which is potentially developed for supporting food availability in the future. Indonesian Coastal land area covers 20.1 million hectares, 6 million ha of which are potential for crops. The high salinity that constrains agricultural development can be minimized by applying the appropriate technology such as varieties that tolerance to salinity, and application of manure and bio-fertilizer that containing the potential microbes to improve plant resistance to environmental stress. This study aimed to obtain information of maize adaptable varieties and fertilization to improve maize productivity in coastal land. The study was conducted at Meranti Coastal Land in 2017 using the randomized block design with 4 treatments and 5 replications. Varieties of maize used were Bisma, Bima 9, Bima 19 URI and Bisi 2. To increase the land productivity, cow manure and cow manure + biological fertilizer with containing nitrogen fixing and phosphate solubilizing microbe were applied. The results showed that the enrichment of biological fertilizer can improve the performance and yield of maize in coastal land that exposed to salt. Variety of Bisi 2 showed high adaptation to environmental stress followed by Bima 19 URI, Bisma and Bima 9.
