Abstract
Green amaranth (Amaranthus tricolor L.) is a nutritious leafy vegetable widely cultivated in Indonesia. This study aimed to evaluate the effects of sunlight intensity and mycorrhizal biofertilizer dosage on the growth and yield of green amaranth. A Split Plot Design was used with three levels of sunlight intensity (50%, 75%, and 100%) as the main plots and four levels of mycorrhizal doses (0 g. 4 g. 6 g. and 8 g per polybag) as subplots, each replicated three times. Parameters observed included plant height, leaf width, number of leaves, leaf length, and root colonization. Data were analyzed using ANOVA followed by DMRT at a 5% significance level. The results showed that sunlight intensity significantly affected plant height at 3 weeks after planting (WAP) and leaf length at 4 WAP. Mycorrhizal dosage significantly affected plant height at 1 WAP, leaf width at 4 WAP, and leaf length at 4 WAP. A significant interaction between sunlight intensity and mycorrhizal dose was observed on leaf length at 4 WAP. No significant effect was found on the number of leaves. Plants grown under full sunlight tended to have greater height and leaf length. However, mycorrhizal treatment did not consistently improve growth, likely due to colonization failure as seen in microscopic observation. In conclusion, sunlight intensity had a greater influence on green amaranth growth than mycorrhizal application under the study's environmental conditions.

| Additional Information: | Bayam hijau (Amaranthus tricolor L.) merupakan sayuran daun bergizi yang banyak dibudidayakan di Indonesia. Penelitian ini bertujuan untuk mengevaluasi pengaruh intensitas cahaya matahari dan dosis pupuk hayati mikoriza terhadap pertumbuhan dan hasil bayam hijau. Penelitian menggunakan Rancangan Petak Terbagi (Split Plot Design) dengan tiga tingkat intensitas cahaya matahari (50%, 75%, dan 100%) sebagai petak utama dan empat tingkat dosis mikoriza (0 g, 4 g, 6 g, dan 8 g per polybag) sebagai anak petak, masing-masing diulang sebanyak tiga kali. Parameter yang diamati meliputi tinggi tanaman, lebar daun, jumlah daun, panjang daun, dan kolonisasi akar. Data dianalisis menggunakan ANOVA yang dilanjutkan dengan uji DMRT pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari berpengaruh nyata terhadap tinggi tanaman pada 3 minggu setelah tanam (MST) dan panjang daun pada 4 MST. Dosis mikoriza berpengaruh nyata terhadap tinggi tanaman pada 1 MST, lebar daun pada 4 MST, dan panjang daun pada 4 MST. Terdapat interaksi yang nyata antara intensitas cahaya matahari dan dosis mikoriza terhadap panjang daun pada 4 MST. Tidak ditemukan pengaruh yang signifikan terhadap jumlah daun. Tanaman yang tumbuh di bawah sinar matahari penuh cenderung memiliki tinggi dan panjang daun yang lebih besar. Namun, perlakuan mikoriza tidak secara konsisten meningkatkan pertumbuhan, kemungkinan disebabkan oleh kegagalan kolonisasi yang terlihat melalui pengamatan mikroskopis. Kesimpulannya, intensitas cahaya matahari memiliki pengaruh yang lebih besar terhadap pertumbuhan bayam hijau dibandingkan aplikasi mikoriza pada kondisi lingkungan penelitian ini. | |||||||||
