Foliar application of micro cattle bone ash in increasing growth and yield of sweet corn (Zea mays saccharata Sturt.)

Abstract

Cattle bone ash contains high calcium and phosphor that can be used as foliar fertilizer. The foliar application requires particles whose size must be smaller than the stomatal size. The study is expected to increase the growth and the production of sweet corn by applying cattle bone ash to sweet corn through foliar application. The experiment was conducted in a complete randomized design with five treatments; without cattle bone ash application, 0.1 %, 0.2 %, 0.3%, and 0.4% of cattle bone ash concentration. Cattle bone ash dominated with particles smaller than stomatal size and contained high calcium, oxygen and phosphor with little of sodium and magnesium. The result showed that 0.3% application of micro cattle bone ash could enhance leaves area, root dry weight, net assimilation rate, ear weight, and 100 kernels weight of sweet corn.

Effectiveness of Cattle Bone Ash Nano Particle as a Source of P to Replace SP 36 Fertilizer in Sweet Corn Cultivation in Entisol soil

“…Based on Electron Diverse X-rays Spectroscopy (EDXS), cattle bone ash that through nanofication using wet method contain calcium (26.06%), phosphor (13,27%), oxygen (58.8%), photassium (1.15%) and magnesium (0.71%). Generally, cattle bones ash have formula of Ca5(OH)(PO4)3 (6). Oxygen becomes dominant element because major compound in the form of oxides [9].…”

“…Ikumapayi and Akinlabi [9] mentioned that cow bones powder contain 18.3% calcium, 7.5% phosphor, 0.4% natrium, and 0.3% magnesium. Mulyono [6] mentioned that cattle bones ash contain 42.8% calcium, 38.8% oxygen, 16.85% phosphor, 1.08% sodium and 0.71% magnesium.…”

“…The bone was placed in muffin furnace with 800°C for two hours to and then placed on hammer mill to created white ash powder. The method for nanofication was using modified technique use by Mulyono et al [6]. with the difference occurs in time for running time.…”

“…Another function is as a raw material to form several certain proteins, help assimilation, respiration, in addition to accelerating flowering, ripening of seeds and fruits [5] Cattle bones is containing macro nutrients in the form of Phosphorus (P). cattle bones contain 42.8% calcium, 16.85% phosphor, 1.08% sodium and 0.71% magnesium [6]. Based on the content contained in cow bones, cow bones can be used as a source of Phosphorus for plants if the size is reduced to ash or nano to facilitate absorption by plant roots, so as to reduce the use of inorganic fertilizers in plant cultivation, besides that it can also reduce household waste.…”

Physiological Response, Growth, and Yield of Edamame Soybean (Glycine Max L. Merr.) Under Foliar Application of Nano Cattle Bone Ash in Entisol

“…To make a smaller size of cattle bone ash, a milling process was carried out for 4 hours with a ball mill tool that produces particles with a size of 118-300 nm. Foliar application through the leaves with a concentration of 0.3% on corn plants can increase leaf area, root dry weight, NAR, the weight of one hundred seeds, and the weight of cobs (Mulyono & Hidayat, 2020). The results of milling still produce a particle size above 100 nm, so we need to study the process of milling to obtain particle sizes below 100 nm by increasing the duration of milling to 6 hours.…”
