Study of “ Turiman Jale 2-7” system production in acid dry agroecosystem in Lampung Region

Abstract Acid dry land is characterized as suboptimal land with low productivity. The “Turiman Jale 2-7” corn-soybean intercropping technology innovation has the potential to provide additional yields on acid dry land.

Description
Summary:Abstract Acid dry land is characterized as suboptimal land with low productivity. The “Turiman Jale 2-7” corn-soybean intercropping technology innovation has the potential to provide additional yields on acid dry land. The purpose of this study was to examine the yields of corn and soybeans grown using the “Turiman Jale 2-7” system on acid dry land. The assessment was carried out at the Tegineneng Experimental Garden, Mandah Village, Natar District, South Lampung Regency, Lampung Province. Methods with demonstration plots in the field of 0.75 ha, with 2 treatments using corn and soybean varieties. The research period was January to June 2020. The soybean varieties planted were Dega, Dena, Detam, Detap, Devon, and local Tanggamus. Corn varieties planted were Balitbangtan JH-37 and existing hybrid corn (Bisi-18, DK-771, NK-22. P-27). The corn-soybean intercropping system used a pattern of alternating 2 rows of corn and 7 rows of soybeans. Corn crop rows used a zigzag cropping pattern. The data observed were components of plant vegetative and generative growth. Data analysis using factorial analysis of variance. The results showed the “Turiman Jale 2-7” system produced an average corn productivity of 14,110 kg/ha and an average soybean productivity of 2,370 kg/ha. The “Turiman Jale 2-7” system is able to optimize the productivity of acid dry land which relies on rainwater. The innovation “Turiman Jale 2-7” contributed to increasing the Cropping Index (CI) from CI = 100 to CI = 150-200.
