Effects of Appropriate Composition of Sugarcane Bagasse Compost and Nitrogen Fertilizer on the Growth and Yield of Soybean (Glycine max L. Merill)

Abstract

The increase of annual soybean import in Indonesia is attributed to the increase of national consumption and low production of soybean. This is mainly due to the decrease in soil fertility as a result of excessive use of synthetic fertilizer leading to the low soybean productivity and production. One of the attempts to increase soil fertility and soybean productivity is by reducing the use of synthetic fertilizer N and optimizing the use of organic fertilizer such as sugar cane bagasse compost rich of Nitrogen. On this account, this research aims to determine the appropriate mixture of sugar cane bagasse compost and ertilizer N on the growth and yield of soybean. This research applies single factor experiment method arranged in Complete Random Design (CRD) consisting of five treatments, namely 100% N from urea (control), 25% N (sugar cane bagasse compost) + 75% N (from urea), 50% N (from sugar cane bagasse compost) + 50 % N (from urea), 75% N (from sugar cane bagasse compost) + 25% N (from urea), 100% N (from sugar cane bagasse compost). It is revealed that the mixture of 75% sugar cane bagasse compost and 25% fertilizer N from urea is the most appropriate composition for the 8.76 ton/ha soybean yield.

Effect of formulated biochar on nodule production, dry matter and grain yield of black soybean (Glycine max (L.) Merr) in Indonesia

“…The combination of phosphate and other fertilizer give a significant effect on the number of pods per polybag and the number of filled pods of soybean, with TSP + dolomite giving the best result compared to control [23]. The application of sugar cane compost + N fertilizer, in various doses were given the same impact as those given with sugarcane compost only or N fertilizer only on the growth of soybean plants (plant height, number of leaves, flower to pod percentage) and component yield (number of pods/plant, filled pod percentage, dry pod weight/plant, number of seeds/plant) [24]. This finding concludes that formulated biochar as soil conditioner and soil boosters could be used to improve the growth and grain yield of black soybean to improve food and nutrition security both on a local and global scale.…”

Optimasi Kondisi Ektraksi Vanillin Hasil Degradasi Lignoselulosa Bagas Tebu Menggunakan Response Surface Method (Rsm)

“…Pada industri gula, bagas tebu merupakan salah satu produk samping yang tersisa setelah batang tebu diekstrak untuk menghasilkan gula (Chandel et al 2011;Solomon 2011). Bagas tebu yang dihasilkan sekitar 35-40% dari setiap tebu yang diproses (Yusuf et al 2018). Sekitar 60% dari total bagas tebu yang dihasilkan dimanfaatkan sebagai bahan bakar pada pabrik gula, bahan baku untuk kertas, bahan baku industri kampas rem, industri jamur, dan lain-lain.…”

Cost Assessment of Utilizing Bagasse to Grow Sugarcane Based on Nutrient Availability

“…The use of inorganic fertilizers that aim to boost productivity dates to the latter half of the 20th century, whereas traditional (mostly organic) fertilizer practices have been used for many millennia (Hergert, Nielsen, and Margheim 2015). The continuous use of inorganic fertilizers is expensive, and it can reduce land productivity (Yusuf et al 2018). Research has shown that not all the fertilizer (mostly inorganic) applied to the soil is taken up by the crop.…”

“…The interactions in soil between organic amendments and inorganic fertilizers are complex. Organic amendments such as bagasse and compost will offset at least a portion of the cost of inorganic fertilizers and are documented to reduce nutrient loss and increase fertilizer use efficiency (Yusuf et al 2018;Vanlauwe et al 2011).…”
