Abstract

To overcome insufficient sweet corn production in Indonesia, various strategies have been developed to improve its production. This study was conducted to evaluate the effect of organic fertilizer (i.e. cow manure) and inorganic fertilizer application on nutrient uptake and yield of sweet corn (Zea mays saccharata Sturt). Inceptisol possess low soil fertility and relatively low to moderate level of organic matter content. Application of organic fertilizer in combination with inorganic fertilizers is expected to increase N, P and K uptake and yield of sweet corn. This study was conducted from October 2016 to February 2017 at the Field Experimental Station of Agriculture Faculty, Universitas Padjadjaran in Jatinangor, West Java. The study was performed in a Randomized Block Design consisting of 10 treatments and 3 replications. The treatments were as follow: A = Control, B = Standard NPK, C = 0 NPK + 1 organic fertilizer, D = ¼ NPK + 1 organic fertilizer, E = ½ NPK + 1 organic fertilizer,  F = ¾ NPK + 1 organic fertilizer, G = 1 NPK + 1 organic fertilizer, H = ¾ NPK + ¼ organic fertilizer, I = ¾ NPK + ½ organic fertilizer and J = ¾ NPK + ¾ organic fertilizer. The results showed that the treatment I (¾ NPK + ½ organic fertilizer) resulted in the highest N, P and K uptake, i.e. 54.31 mg plant-1; 82.85 mg plant-1 and 56.40 mg plant-1, respectively and the heaviest weight of sweet corn, i.e. 407.33 g.

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.

Abstract

Nitrogen is an essential soil nutrient that is often a limiting factor in agricultural practices due to its tendency to be easily lost from the soil through various natural processes. Maintaining and increasing nitrogen availability in the soil is a primary focus in efforts to increase agricultural productivity. The purpose of this article is to provide information on the potential of various compost and biochar materials as soil amendments. The method used was a literature review to collect data related to compost and biochar. Various sources of compost and biochar contain varying nutrient contents, which have the potential to increase nitrogen availability in the soil. Compost application to the soil contributes to the nitrogen cycle through mineralization and immobilization processes, and nitrogen adsorption by biochar can reduce nitrogen leaching. The application of various types of compost or a combination with biochar is recommended to maintain nutrient balance and improve soil quality. Future research can explore further to determine optimal strategies for compost and biochar application to support more productive and sustainable agriculture.

Abstract

The inefficiency of chemical fertilizers in crop production has encouraged the development of more sustainable and environmentally friendly alternatives. One of the approaches is through the useof organic fertilizers enriched with beneficial microorganisms. This study aimed to evaluate the effectof N, P, K fertilizers combination with kasgot (vermicompost derived from sewage sludge) enrichedwith biofertilizers on the yield of sweet corn (Zea mays L.) grown on Inceptisols. The experiment wasconducted from February to September 2024 at the Experimental Field of the Faculty of Agriculture,Universitas Padjadjaran, Jatinangor. A Randomized Complete Block Design was used, consisted ofeight treatments: one control (no fertilizer), one treatment with the recommended N, P, K dose, onetreatment with ¾ of the recommended dose of inorganic fertilizer, and and five treatments withvarious doses of kasgot enriched with biofertilizers and NPK fertilizers. Each treatment was replicatedthree times. The results showed that the combination of ¾ NPK dose and 1½ dose of enriched withbiofertilizers resulted in the best growth and yield performance. This treatment produced the highestear weight with husk (495.95 g), ear length (20.56 cm), and ear diameter (56.00 mm) compared toother treatments. The result suggested that the integrated application of biofertilizers and reduceddoses of chemical fertilizers can improve sweet corn yield while minimize the dependence on syntheticinputs, which promotes more sustainable and efficient agricultural practices.

Abstract

Pertumbuhan dan produksi tanaman dipengaruhi oleh berbagai karakteristik tanah terutama kesuburan tanah yang berkaitan dengan ketersediaan unsur hara. Pengelolaan kesuburan  tanah harus diperhatikan agar tanah dapat menyokong pertumbuhan dan hasil tanaman yang tinggi dalam jangka waktu yang lama. Percobaan ini bertujuan untuk mencari dosis pupuk Si terbaik terhadap perubahan kandungan unsur hara tanah, pertumbuhan tanaman dan hasil panen tanaman jagung manis. Percobaan ini dilaksanakan di Kebun Percobaan Laboratorium Kimia Tanah dan Nutrisi Tanaman Fakultas Pertanian, Universitas Padjadjaran, Jatinangor, Sumedang pada bulan Mei sampai Agustus 2021. Rancangan penelitian yang digunakan yaitu Rancangan Acak Kelompok (RAK) yang terdiri dari sembilan perlakuan dan diulang tiga kali, yaitu: kontrol; N, P, K rekomendasi; ¼ dosis pupuk Si + 1 dosis N, P, K rekomendasi; ½ dosis pupuk Si + 1 dosis N, P, K rekomendasi; ¾ dosis pupuk Si + 1 dosis pupuk N, P, K; 1 dosis pupuk Si + 1 dosis pupuk N, P, K; 1 ¼ dosis pupuk Si + 1 dosis pupuk N, P, K; 1 ½ dosis pupuk Si + 1 dosis pupuk N, P, K; dan 1 ¾ dosis pupuk Si + 1 dosis pupuk N, P, K. Hasil percobaan menunjukkan bahwa perlakuan 1 ½ dosis pupuk Si + 1 dosis pupuk N, P, K mampu memberikan pengaruh terbaik dalam meningkatkan kandungan Si tanah dan meningkatkan hasil panen tanaman jagung manis.
