| dc.description.abstract | Jambu biji (Psidium guajava L.) var. Kristal merupakan salah satu buah yang banyak diminati masyarakat Indonesia dengan ciri khasnya berupa kandungan vitamin C yang tinggi, tekstur buah renyah, serta persentase biji kurang dari 3%. Diperlukan upaya untuk memenuhi permintaan kebutuhan jambu kristal melalui perbaikan pembungaan dan pembuahan. Penelitian ini bertujuan menguji efektivitas pupuk hayati dalam meningkatkan penyerapan hara selama proses pembungaan dan pembuahan. Penelitian dilaksanakan di Kebun Percobaan Cikabayan Bawah, Departemen Agronomi dan Hortikultura, Fakultas Pertanian,
Institut Pertanian Bogor, pada bulan Juni 2023 hingga Januari 2024. Rancangan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) satu faktor dengan empat taraf dosis pupuk hayati cair per-tanaman: 0, 36, 45, dan 54 ml. Pupuk hayati yang digunakan merupakan pupuk hayati cair dengan kandungan mikroba Azotobacter sp, Azospirillum sp, Bacillus sp, Pseudomonas sp, Rhizobium sp, dan Trichoderma sp. Setiap perlakuan terdiri atas enam ulangan sehingga terdapat 24 satuan percobaan. Hasil penelitian menunjukkan bahwa
pemberian pupuk hayati berpengaruh nyata terhadap jumlah tunas vegetatif, generatif, dan jumlah bunga, tetapi tidak berpengaruh terhadap kualitas fisik maupun internal buah. Dosis 54 ml tanaman-1 menghasilkan rata-rata jumlah bunga dan rata-rata bobot total buah per tanaman tertinggi masing-masing 128,25 bunga dan 983,10 g tanaman-1. Peningkatan dosis pupuk hayati mampu memperbaiki pertumbuhan vegetatif dan generatif tanaman jambu kristal. | |
| dc.description.abstract | ‘Crystal’ guava (Psidium guajava L.) is one of the fruits that widely preferred by Indonesians, characterized by its high vitamin C content, crisp texture, and seed content of less than 3%. Efforts are needed to meet the demand for crystal guava through improved flowering and fruiting. This study aims to test the effectiveness of biofertilizers in increasing nutrient absorption during the flowering and fruiting process. The study was conducted at the Cikabayan Experimental Garden, Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University, from June 2023 to January 2024. The design used was a one-factor Randomized Complete Block Design (RCBD) with four levels of liquid biofertilizer dosage per plant: 0, 36, 45, and 54 ml. The biofertilizer used was a liquid biofertilizer containing microbes Azotobacter sp, Azospirillum sp, Bacillus sp, Pseudomonas sp, Rhizobium sp, and Trichoderma sp. Each treatment consisted of six replications, resulting in 24 experimental units. The results showed that the application of biofertilizer significantly affected the number of vegetative and generative shoots, and the number of flowers, but did not affect the physical or internal quality of the fruit. A dose of 54 ml plant-1 produced the highest average number of flowers and total
fruit weight at 118,25 flowers and 983,10 g plant-1, respectively. Increasing the dose of biofertilizer improved the vegetative and generative growth of crystal guava plants. | |
