Penambahan Unsur Hara Makro-Mikro untuk Meningkatkan Efektivitas Provibio terhadap Produksi Tanaman Padi

Abstract

Penurunan produktivitas lahan sawah akibat penggunaan intensif pupuk sintetik mendorong perlunya alternatif yang ramah lingkungan seperti pupuk hayati. Penelitian ini bertujuan mengetahui pengaruh pemberian variasi dosis pupuk makro-mikro yang dikombinasikan dengan pupuk hayati Provibio terhadap produktivitas tanaman padi (Oryza sativa L.) varietas IF20. Penelitian dilaksanakan di lahan ICBB Situgede, Bogor menggunakan Rancangan Acak Kelompok (RAK) dengan delapan perlakuan dan tiga ulangan. Hasil penelitian menunjukkan bahwa pemberian Provibio tanpa tambahan unsur hara makro-mikro (perlakuan F0) memberikan hasil yang cenderung lebih baik dalam hal produktivitas gabah, bobot 1000 bulir, dan biomassa tanaman, tanpa perbedaan signifikan secara statistik dibanding perlakuan kombinasi. Penambahan unsur hara makro-mikro tidak meningkatkan hasil produksi dan cenderung menurunkan aktivitas mikrob tanah. Provibio terbukti efektif meningkatkan hasil pertumbuhan generatif padi melalui aktivitas mikrob fungsional yang dikandungnya. Penggunaan Provibio tanpa penambahan hara makro mikro mampu meningkatkan produksi padi hampir 1 ton GKP/ha dibanding hanya menggunakan pupuk sintetik saja.

The decline in productivity of rice fields due to the intensive use of inorganic fertilizers encourages the need for environmentally friendly alternatives such as bio-fertilizers. This research aims to determine the effect of the combination of macro-micro and Provibio bio-fertilizer on rice productions variety IF20. The study was conducted in the ICBB Situgede area, Bogor, using a Randomized Block Design (RBD) with eight treatments and three replications. The results showed that the application of Provibio without the addition of macro micro nutrients (treatment F0) provided better results in terms of grain productivity, weight of 1000 grains, and plant biomass, with no statistically significant difference compared to the combination treatment. The addition of macro-micro nutrients did not increase production yields and tended to reduce soil microbial activity. Provibio has been proven to effectively increase the generative growth results of rice through the functional microbial activity it contains. The use of Provibio without the addition of macro-micro nutrients can increase rice production by nearly 1 ton of dry grain per hectare compared to just using synthetic fertilizers.
