Pertumbuhan dan Hasil Jagung Hibrida pada Pola Tanam Tumpangsari dengan Kedelai di Arjasari Kabupaten Bandung

Abstract

Maize and soybean are important food after paddy in Indonesia. Maize and soybean consumption will continue to increase every year due to population growth. One of the ways to increase crop production can be done by intercropping. Intercropping is a planting system by growing two or more crops simultaneously on the same land in one year. The objective of this research was to determine appropriate maize hybrid genotype and soybean combinations in intercropping system. The experiment was carried out from March 2016 to August 2016 at Arjasari, Bandung Regency with altitude about 960 m above the sea level. The experiment used was Randomized Block Design (RBD) which consisted of twenty treatments and two replications. The treatment was eighteen genotypes and two check genotypes which consisted of F1B X 4.8.8, F1E X 1.1.3, F1D X 3.1.4, F1F X G203, F1A X 4.8.8,, F1E X 3.1.4, F1H X G-673, F1I X G203, F1B X 1.1.3, F1E X 3.1.4, F1C X G203-1, F1G X 16.5.15, F1D X 16.5.15, F1H X 1.1.3, F1A X 16.5.15, F1I X G673, F1G X 673, F1C X 4.8.8, Maros 1 x 2 and Maros 11 x 12. Each genotypes intercropped with soybean plants.The result of the experiment showed that the treatment of intercropping maize and soybean could affect the growth and the production of maize genotypes F1F x 3.1.4, Maros 1 x 2 ,and Maros 11 x 12. The treatment of maize hybrid genotypes F1B x 1.1.3, F1B x 4.8.8, F1I x G203-1, Maros 1 x 2 and Maros 11 x 12 intercropped with soybean gave the best effect on the dry seed grain weight per plot reaching 2,60-3,30 kg/m 2 equal to5,77-7,34 ton/ha.
