Diagnosis Visual Masalah Unsur Hara Esensial Pada Berbagai Jenis Tanaman

Abstract: Unsur hara esensial merupakan unsur kimia yang dibutuhkan oleh tanaman untuk menunjang pertumbuhan dan perkembangannya. Unsur hara esensial berdasarkan tingkat kebutuhan tanaman dibedakan menjadi tiga yaitu unsur hara dasar (basic nutrient), unsur hara makro (makronutrien), dan unsur hara mikro (mikronutrien). Tanaman berpotensi untuk mengalami masalah unsur hara, baik itu defisiensi maupun toksisitas. Defisiensi dan toksisitas unsur hara yang dialami oleh tanaman dapat diketahui dengan melakukan diagnosis vis… Show more

“…The mechanism of the process is that WRKY33 will trigger the regulation of genes that are responsive to auxin hormones to increase plant root growth and be able to retrieve nitrogen more efficiently [27]. On the other hand, the expression on day 28 has decreased; supposedly, nitrogen and phosphorus nutrients in plants have been sufficient, so plants reduce the level of nutrient use to avoid nutrient toxicity [28].…”

“…Table 3 shows that the 100% peat treatment did not show significant growth in the diameter of geronggang seedlings, due to insufficient nutrient content. According to Armita et al (2022), nutrients in the planting media if the availability is less or excessive, it can affect plant growth. According to Shafira et la.…”

“…Sehingga kebutuhan tanaman akan molybdenum penjadi sangat penting. Tetapi keberadaan molybdenum sebagai elemen yang jarang menyebabkan perlunya pertimbangan keberadaan molybdenum dalam pertumbuhan tanaman (Armita et al, 2022). Pemberian konsentrasi Mo lebih dari 0,36 gram per tanaman atau 15,12 gram per tanaman selama periode tanam dapat meningkatkan pertumbuhan dan produksi tanaman melon (Islami et al, 2014).…”
