Increasing broccoli yield and quality is essential to meet consumer expectations for nutrient-rich vegetables. Implementing a balanced mix of chemical fertilizers and biofertilizers may support this goal. A greenhouse experiment was conducted to examine the effect of Bacillus-coated NPK combined fertilizer (BCN) on the growth, nutrient uptake, yield, and vitamin content of broccoli heads. The experiment was arranged in a Randomized Block Design with seven treatments and four replications. These treatments included different combinations of BCN type and dose, two levels of NPK, and a control without fertilizer. Results showed that BCN did not affect plant growth or N, P, and K content in the soil, but it increased the chlorophyll content index, nutrient uptake, and the shoot-to-root ratio. Although BCN did not influence yield, it enhanced Vitamin B-complex and K levels in the broccoli heads. The study concluded that in this short-term experiment, BCN improved N, P, and K levels in the shoots and increased the nutritional value of broccoli heads.
ABSTRAK
Peningkatan hasil dan kualitas brokoli merupakan salah satu cara untuk memenuhi harapan konsumen akan sayuran bernilai gizi tinggi. Penerapan pupuk berimbang antara pupuk kimia dan pupuk hayati dapat mendukung harapan tersebut. Percobaan di rumah kaca dilakukan untuk mengamati pengaruh pupuk kombinasi NPK berlapis Bacillus (NBB) terhadap pertumbuhan, penyerapan hara, hasil, dan kandungan vitamin pada bonggol brokoli. Percobaan disusun dalam Rancangan Acak Kelompok, terdiri dari tujuh perlakuan dan empat ulangan. Perlakuan tersebut terdiri dari kombinasi jenis dan dosis NBB, dua dosis NPK, dan satu perlakuan kontrol tanpa

Peningkatan hasil dan kualitas brokoli merupakan salah satu cara untuk memenuhi harapan konsumen akan sayuran bernilai gizi tinggi. Penerapan pupuk berimbang antara pupuk kimia dan pupuk hayati dapat mendukung harapan tersebut. Percobaan di rumah kaca dilakukan untuk mengamati pengaruh pupuk kombinasi NPK berlapis Bacillus (NBB) terhadap pertumbuhan, penyerapan hara, hasil, dan kandungan vitamin pada bonggol brokoli. Percobaan disusun dalam Rancangan Acak Kelompok, terdiri dari tujuh perlakuan dan empat ulangan. Perlakuan tersebut terdiri dari kombinasi jenis dan dosis NBB, dua dosis NPK, dan satu perlakuan kontrol tanpa pupuk. Hasil penelitian menunjukkan bahwa NBB tidak memengaruhi pertumbuhan tanaman dan kandungan N, P, dan K dalam tanah, tetapi meningkatkan indeks kandungan klorofil, penyerapan hara, dan rasio pucuk terhadap akar. Meskipun tidak mempengaruhi hasil panen, NBB meningkatkan vitamin B kompleks dan K di bunga brokoli. Penelitian ini menyimpulkan bahwa dalam percobaan jangka pendek, NBB meningkatkan nutrisi N, P, dan K pada tajuk serta nilai gizi bunga brokoli.
