Penampilan Sepuluh Varietas Kedelai Yang Ditumpangsarikan Dengan Tebu

Abstract

[PERFORMANCES OF TEN SOYBEAN VARIETIES AS INTERCROPPED WITH SUGARCANE]. An intercropping system between soybean and sugarcane may be an alternative to increase soybean production in Indonesia, but not all soybean varieties are suitable for intercropping system as different soybean varieties may perform differently under intercropping system and monoculture system. Therefore, suitable soybean varieties for intercropping should be identified to warrant the higher crop productivity. This study was conducted to to compare the growth and yield performances of ten soybean varieties in monoculture and soybean-sugarcane intercropping systems. The experiment was laid in a Split Plot Design with three replications. The cropping systems (monoculture and intercrop) were allotted in the main plots, while the soybean varieties (Gepak Kuning, Kaba, Wilis, Tanggamus, Burarang, Sinabung, Anjasmoro, Agromulyo, Ring-1, and Gema) were assigned as the sub plots and allotted randomly in each main plot. On overall, the intercropping system had significantly reduced the soybean pod number, seed number, wight of 100 seed, and, seed yield/plant, but increased plant height as compared to the monoculture system. The exceptions were observed for seed number and weight of 100 seed. The reduction of seed number was not significant on Agromulyo and Dering-1.On the other hand, Anjasmoro and Dering-1were the only varieties showed significant reduction in weight of 100 seed. Kaba, Willis, Tanggamus, Burarang, Sinabung, and Dering-1 showed their consistant performormances across the cropping systems. However, the higher seed yield/plant in both systems was observed on Gepak Kuning, Willis, Burarang, Agromulyo, Dering-1, and Gema.

Pemanfaatan Sistem Tanam Tumpangsari terhadap Pertumbuhan Vegetatif Dua Kultivar Tanaman Kedelai Hitam (Gylcine Max L)

“…Berdasarkan Tabel 1 menunjukkan bahwa pengukuran tinggi tanaman pada perlakuan kultivar kedelai berpengaruh nyata, tetapi pada perlakuan jarak tanam tidam memberikan pengaruh nyata. Hal ini disebabkan karena adaptasi tanaman kedelai terhadap lingkungan yang penuh tekanan melibatkan pertumbuhan tinggi batang dalam kondisi ternaungi sehingga cahaya dapat masuk ke kanopi tanaman (Umarie et al, 2019). Dalam sistem tumpang sari, salah satu penghambat pertumbuhan dan hasil tanaman yang paling utama adalah persaingan intensitas cahaya dalam fotosintesis.…”

“…Hasil penelitian Umarie et al (2018) menunjukkan bahwa secara umum, kedelai yang ditumpangsarikan dengan tebu secara nyata mengalami penurunan jumlah polong, jumlah biji, bobot 100 biji. dan hasil biji/tanaman tetapi tanamannya menjadi lebih tinggi dibanding kedelai yang ditanam secara monokultur.…”

Effect Of Weeding and Pest Control on Root Dynamics of Soybean (Glycine max (L.) Merril) on Sugarcane-Soybean Intercropping System

“…Soybean (Glycine max (L.) Merill) is one of the important commodities in the provision of food, feed, and industrial materials, so it has become a major commodity in international trade [1], [2], [3] [4], [5]. Total world production for soybeans in 2016 reached 334,894,085 metric ton.…”
