Abstract

AbstrakSalah satu strategi yang diterapkan pada pupuk hayati untuk menunjukkan efek positif pada tanaman yang diinokulasi adalah pemilihan teknik aplikasi dan dosis yang tepat, baik pada tanah, benih, atau kombinasi keduanya. Tujuan dari percobaan ini adalah mendapatkan teknik aplikasi dan dosis pupuk hayati pelarut K yang memberikan hasil terbaik terhadap penyerapan K dan pertumbuhan tanaman jagung (Zea mays L.) pada Inceptisols Jatinangor. Percobaan dilaksanakan pada November 2018-Januari 2019 di rumah kaca Fakultas Pertanian Universitas Padjadjaran. Percobaan menggunakan rancangan acak kelompok dengan 9 perlakuan dan 3 kali ulangan. Perlakuan terdiri dari tanpa perlakuan (kontrol), aplikasi pada benih 400 g.ha-1 dan 800 g.ha-1, aplikasi pada tanah 2 kg.ha-1 dan 4 kg.ha-1, dan kombinasi antara kedua teknik aplikasi dan dosis tersebut. Hasil percobaan menunjukkan aplikasi pupuk hayati pelarut K dengan dosis 4 kg.ha-1 dapat meningkatkan populasi BPK total 52,86% dibandingkan kontrol dan berkorelasi positif terhadap konsentrasi K2O (r=0,64**), serapan K (r=0,59**), dan diameter batang tanaman jagung (r=0,46*) yang dibudidayakan di tanah Inceptisols Jatinangor.Kata Kunci: Aplikasi pada tanah ∙ Aplikasi pada benih ∙ Bakteri pelarut kalium ∙ Dosis ∙ Jagung AbstractOne of the strategies applied to biofertilizers to show a positive effect on the inoculated plants is the selection of the appropriate application technique and dose in soil, seeds, or a combination of both. The purpose of this experiment was to obtain the application technique and dose of potassium (K) solubilizing biofertilizer that gave the best results on K uptake and growth of maize (Zea mays L.) on Inceptisols of Jatinangor. The experiment was performed in November 2018-January 2019 in the greenhouse of the Faculty of Agriculture, Universitas Padjadjaran. The experiment used a single factor randomized block design with 9 treatments and 3 replications. The treatments consisted of control, seed treatment at doses of 400 g.ha-1 and 800 g.ha-1, soil treatment at doses of 2 kg.ha-1 and 4 kg.ha-1, and a combination of the two techniques application and doses. The results showed that the application of K solubilizing biofertilizer at a dose of 4 kg.ha-1 could increase the total PSB population by 52.86% compared to control and it was positively correlated with concentration of K2O (r=0.64**), K uptake (r=0.59**), and maize stem diameter (r=0.46*) grown on Inceptisols of Jatinangor.Keywords: Soil treatment ∙ Seed treatment ∙ Potassium solubilizing bacteria ∙ Dose ∙ Maize

Abstract

. Water hyacinth (Eichhornia crassipes) is a source of organic matter that can be used as compost to improve the soil quality and productivity of shallots. Shallots are horticultural commodities that have various benefits. Inceptisol soils dominate Indonesia, with an area of 37.5% of Indonesia's land area but have low soil fertility. Soil fertility can be increased by optimal fertilization. This experiment aimed to determine the dose of water hyacinth compost and nitrogen (N), phosphor (P), potassium (K), sulfur (S) fertilizer which gave the best effect on increasing available S, S uptake, protein content, and yield of shallots. The experiment was conducted from July to October 2021 at the Experimental Garden of the Laboratory of Soil Chemistry and Plant Nutrition, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. The experiment used a Randomized Block Design, consisting of seven treatments repeated four times. The recommended fertilizer doses used are 200 kg Urea, 500 kg ZA, 300 kg SP-36, and 200 kg KCl. The compost used was water hyacinth compost at a 25 t/ha dose. The results of this experiment showed that the treatment of ¾ compost + ¾ doses of N, P, K, and S was the best in increasing available S (26.79 mg kg-1), S uptake (7.03 mg/plant), protein content (0.95%), colors and shallot yield (number of tubers, fresh weight, and dry weight) on Inceptisols from Jatinangor.

Abstract

Sustainable rice farming is increasingly threatened by declining soil fertility, excessive reliance on chemical fertilizers, and environmental degradation from intensive agricultural practices. There is an urgent need for innovative organic fertilizer products that combine organic materials with macro and micronutrient enhancements to restore soil health effectively. This research aimed to evaluate the effect of organic plus fertilizer (OPF) as a sustainable soil amendment to improve soil nutrient status, increase paddy productivity, and enhance overall soil health. The experiment was conducted using a Randomized Block Design (RBD) with nine treatments: one recommended OPF dose, six combinations of NPK (75 – 100%) and OPF (75 – 150%), one recommended conventional NPK dose, and one control. Variables observed included plant growth, yield, and yield components, total soil nitrogen, and plant uptake of N, P, and K. Results indicated that OPF combined with NPK significantly increased plant height (29.13 – 31.38%) and number of panicles (57.89%) compared to the control. Nutrient uptake improved for nitrogen (23.68%) and potassium (15.96 – 21.28%), although no significant improvement was observed for phosphorus. Yield parameters showed an 81.97%–118.50% increase over the control. The combinations of 75% NPK + 150% OPF, 100% NPK + 75% OPF, and 100% NPK + 100% OPF produced taller plants, higher yields, greater nutrient uptake, and lower residual nitrogen in the soil. For optimal rice yield and soil health, integrated application of OPF with either a full or 75% NPK dose is recommended.
