Abstract

Sorgum (Sorghum bicolor L.) merupakan tanaman pangan fungsional dan alternatif sebagai pengganti beras dan gandum karena mengandung gizi unik dan bebas gluten. Penelitian ini bertujuan untuk mengetahui keragaan hasil dan tingkat keparahan serta kriteria ketahanan penyakit karat daun pada galur F6 sorgum. Penelitian menggunakan Rancangan Augmented yang terdiri dari 20 galur F6 sorgum tanpa ulangan dan 5 varietas pembanding sebagai kontrol dengan 3 ulangan sehingga diperolah 35 satuan percobaan. Data dianalisis dengan uji F dan dilanjutkan dengan Uji BNT pada taraf 5%, kemudian dilanjutkan dengan perhitungan nilai heritabilitas dan korelasi pearson. Hasil penelitian menunjukkan bahwa nilai heritabilitas setiap karakter yang diamati tergolonng tinggi. Tingkat keparahan penyakit karat daun berkorelasi negatif terhadap bobot malai dan bobot biji malai-1  yang menunjukkan adanya tingkat penyakit rendah dengan bobot hasil yang tinggi. Terdapat 7 galur diantaranya A-19-18-3, A-21-14-3, A-21-14-2, A-16-21-5, B-15-25-3, B-1-24-2 dan B-4-6-7 yang memiliki bobot hasil yang baik dan tahan terhadap penyakit karat daun.

Abstract

This study was conducted to determine the effect of Zinnia elegans plant spacing as a refugiaplant on the abundance of natural enemies and the level of pest attacks on soybean (Glycinemax). The study used a non-factorial Randomized Block Design (RBD) with five treatments:no refugia (J0), and plant spacing of 40 cm (J1), 60 cm (J2), 80 cm (J3), and 100 cm (J4),each with four replications. The parameters observed included the identification andpopulation of natural enemy insects, the abundance of natural enemy insects, the area andintensity of pest attacks. Data analysis was carried out using analysis of variance andcontinued with the LSD test at the 5% level. The results showed that the 40 cm plant spacing(J1) was the most effective treatment, resulting in the highest abundance of natural enemies(31 individuals from 4 families) and the lowest pest population (2 individuals). Treatment J1also showed the lowest pest attack area (5.47%) and very light attack intensity (3.62%),while the control (J0) showed an attack area of 23.47% and an attack intensity of 19.42%,which is classified as moderate. The high abundance of natural enemies at a plantingdistance of 40 cm indicates the effectiveness of refugia in creating microhabitats that supportnatural predators in the soybean planting ecosystem. These data indicate that the use ofZinnia elegans refugia at optimal planting distances can suppress pest attacks whileincreasing soybean plant productivity. Therefore, the integration of refugia plants withappropriate planting distances can be an effective, environmentally friendly biologicalcontrol strategy and support sustainable agriculture.
