Penambahan Unsur Hara Makro-Mikro untuk Meningkatkan Efektivitas Provibio terhadap Pertumbuhan Vegetatif Padi

Abstract

Pengembangan pupuk hayati Provibio bertujuan meningkatkan pertanian berkelanjutan dan mengurangi ketergantungan pada pupuk kimia dengan memanfaatkan mikroorganisme untuk meningkatkan produktivitas tanah dan tanaman padi. Kombinasi Provibio dengan unsur hara makro dan mikro, seperti nitrogen, kalium, zinc, dan tembaga, memiliki potensi dalam memperbaiki kesuburan tanah, dan mendukung pertumbuhan vegetatif tanaman padi. Rancangan acak kelompok digunakan dengan 8 perlakuan dan 120 tanaman. Pengamatan vegetatif dinilai pada 15, 30, dan 45 HST, serta saat panen, dengan analisis laboratorium untuk sifat biologi, kimia, dan biokimia tanah. Data dianalisis menggunakan ANOVA dan DMRT untuk perbandingan perlakuan. Perlakuan F0 menunjukkan tinggi tanaman tertinggi 30 HST dan 45 HST, jumlah anakan terbanyak, dan populasi pelarut P tertinggi (124,976×106). F0 juga meningkatkan pH tanah (6,3), C-organik (2,620%), dan aktivitas selulase. Penambahan KNO3 108,2 g/L (F6) menghasilkan N-total tertinggi. Ketidakseimbangan hara dapat menurunkan pertumbuhan tanaman. Kombinasi unsur hara makro-mikro dan pupuk hayati Provibio berpengaruh nyata pada pertumbuhan padi. Provibio meningkatkan tinggi tanaman dan jumlah anakan melalui peran mikrob. Meskipun efektif sendiri, kombinasi dosis tepat unsur hara memengaruhi respons pertumbuhan, aktivitas mikrob, ketersediaan hara, dan aktivitas enzim tanah selama fase vegetatif secara signifikan.

The development of Provibio biofertilizer aims to enhance sustainable agriculture and reduce reliance on chemical fertilizers by utilizing microorganism to improve soil productivity and rice crop yields. The combination of Provibio with macro and micro nutrients, such as nitrogen, potassium, zinc, and copper, has the potential to improve soil fertility and support the vegetative growth of rice plants. A randomized block design was used with 8 treatments and 120 plants. Vegetative observations were assessed at 15, 30, and 45 days after sowing (DAS), as well as at harvest, with laboratory analysis for soil biological, chemical, and biochemical properties. Data were analyzed using ANOVA and DMRT for treatment comparisons. Treatment F0 showed the highest plant height at 30 and 45 HST, the highest number of tillers, and the highest P solubilizer population (124,976×106). F0 also increased soil pH (6.3), organic carbon (2.620%), and cellulase activity. The addition of KNO3 at 108.2 g/L (F6) resulted in the highest total nitrogen content. Nutrient imbalance can reduce plant growth. The combination of macroand micro-nutrients and Provibio biofertilizer significantly influenced rice growth. Provibio enhances plant height and tiller number through microbs activity. Although effective individually, the combination of optimal nutrient doses significantly influences growth response, microbs activity, nutrient availability, and soil enzyme activity during the vegetative phase.
