Abstract

The element Si is a functional nutrient for rice plants. The loss of available Si from paddy fields every time of harvest is relatively high. The impact of reduced available Si content is a decrease in the efficiency of N, P, K fertilization, plant resistance to abiotic and biotic stresses. Si fertilization on paddy plants in Indonesia has not been implemented massively by farmers. Si fertilization by returning rice straw and husks to the paddy field in compost and biochar is a strategic and economical step to replenish the depleted Si reserves of paddy fields. The response of Si fertilization between one region will differ depending on the concentration of Si-available in the paddy soil. The development of the critical limit of Si available for paddy soil in Indonesia needs to be investigated further so that the critical limit of Si can be used as a standard in determining the need for Si fertilization.

Abstract

Pada sistem hidroponik, pemberian pupuk anorganik dan pupuk hayati dilakukan untuk meningkatkan hasil tanaman karena pupuk anorganik menyediakan unsur hara dan pupuk hayati menghasilkan fitohormon yang meningkatkan pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati yang dikombinasikan dengan pupuk anorganik terhadap populasi bakteri pelarut fosfat, kandungan fosfat (P) dan hasil tanaman tomat. Penelitian ini dilakukan menggunakan rancangan acak kelompok (RAK) dengan 7 perlakuan kombinasi pupuk anorganik (konsentrasi 100%, 75%, dan 50%), pupuk hayati (konsentrasi 100%, 75%, 50%, dan 25%) 4 ulangan. Data yang diperoleh dianalisis secara statistik untuk melihat pengaruh perlakuan. Hasil percobaan menunjukkan bahwa kombinasi pupuk anorganik dan pupuk hayati menunjukkan hasil yang tidak berbeda nyata terhadap populasi bakteri pelarut fosfat, kandungan P, dan hasil tanaman tomat pada sistem hidroponik.

Abstract

Tanaman padi (Oryza sativa L.) merupakan komoditas strategis dalam menjaga ketahanan pangan nasional. Berbagai upaya dilakukan agar hasil panen tanaman padi terus meningkat. Aplikasi silika (Si) pada tanaman padi masih jarang dilakukan oleh petani sebagai upaya untuk meningkatkan produktivitas tanaman padi. Penelitian ini bertujuan untuk menentukan konsentrasi terbaik aplikasi Si pada setiap status Si tanah sawah terhadap produktivitas tanaman padi. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan ulangan tidak sama. Terdiri dari sembilan perlakuan yang merupakan kombinasi antara status Si tersedia (rendah, sedang dan tinggi) dan aplikasi Si (tanpa pemupukan, ekstrak silika sekam padi 20 dan 40 mL L-1. Variabel penelitian yang diamati yaitu jumlah malai umur 84 dan 98 hari setelah tanam, berat kering biomassa jerami, berat gabah per 1000 butir, berat gabah per rumpun dan berat gabah konversi per hektar. Hasil penelitian menunjukkan bahwa konsentrasi optimum aplikasi Si berbeda-beda bergantung pada status Si dalam tanah. Level optimum aplikasi Si diperoleh konsentrasi 11 dan 28 mL L-1 untuk Si tersedia sedang dan tinggi. ABSTRACT Rice is a strategic commodity for maintaining national food security. Various efforts are being made to increase rice yields. Application of silica (Si) on rice plants is still rarely carried out by farmers as an effort to increase rice productivity. This study aims to determine the optimal concentration of Si application at each Si status of paddy soil for rice plant productivity. The method used in this study is an experimental method using a completely randomized design with unequal replications. Consisting of nine treatments, a combination of available Si status (low, medium and high) and Si application (no fertilization, rice husk silica extract 20 and 40 mL L-1). The research parameters observed were the number of panicles at 84 and 98 days after planting, dry weight of straw biomass, grain weight per 1000 grains, grain weight per clump and converted grain weight per hectare. The results indicated that the optimal Si application concentration varied according to the soil Si status. The optimum Si application was at concentration of 11 mL L-1 of 28 mL L-1 in paddy soil with a medium and high available Si status, respectively.

Abstract

The application of organic amendments is an important strategy to improve seedling quality in coffee nurseries. This study aimed to evaluate the effects of coffee husk compost and biochar, appliedsingly and in combination, on the growth of Arabica coffee seedlings. The experiment was conductedin a nursery using polybags filled with 5 kg of growing media and arranged in a randomized completeblock design with seven treatments and four replications. The treatments consisted of a control, coffeehusk compost alone, biochar alone, and combinations of compost and biochar at different rates.Growth parameters observed included plant height, stem diameter, and number of leaves. The resultsindicated that all amended treatments significantly improved seedling growth compared to thecontrol. The best growth performance was consistently obtained from the combined application ofcoffee husk compost at 300 g polybag⁻¹ and biochar at 200 g polybag⁻¹, which produced the highestplant height, stem diameter, and leaf number. This treatment demonstrated a synergistic effectbetween coffee husk compost as a nutrient source and biochar as a soil conditioner that improved thegrowing media environment. These findings suggest that the combined use of coffee husk compost andbiochar at appropriate rates is an effective approach to enhance vegetative growth and overall qualityof Arabica coffee seedlings in nursery systems.
