Results of previous research have proven that soil organic matter (humic and biochar compounds) can increase and maintain soil fertility and protect environmental resilience. The purpose of this study was to increase the abundance of microorganisms in young soil (regosol) with biopelet fertilizer composed of a combination of biochar, chicken manure, and shrimp waste to improve soil fertility. The experimental design used was a randomized block design with two factors, namely the composition and dosage of biopelets. The compositions of biopelet were 70% biochar, 15% chicken manure and 15% fish waste (B1); 50% biochar, 25% chicken manure and 25 % fish waste (B2): and 20% biochar, 40% chicken manure and 40% fish waste (B3). The dosage used was four levels (0, 2.5, 5, and 10 t/ha).The results showed that the application of biopelet fertilizer to the regosol soil reduced soil pH from slightly alkaline to near neutral, and the addition of up to 10 t biopelet/ha increased soil organic C content from 1.17% to 1.72%, as well as increasing the availability of N, P, and K nutrients. Improvement in pH, organic-C, and soil macronutrients was followed by an increase in the abundance of soil microorganisms, especially bacteria.

Abstract This study aims to determine the effect of drought stress and mycorrhizal dose on the growth and yield of maize (Zea mays L.). The research was done in the BPTP Banten Screen House and the Soil and Climate Laboratory of the Faculty of Agriculture, Sultan Ageng Tirtayasa University starts from November 2020 until February 2021. This study used a factorial randomized block design (RBD) consisting of two factors. First factor was drought stress with four levels, namely k1 (100% FC), k2 (80% FC), k3 (60% FC), and k4 (40% FC) and second was the mycorrhizal dose with 3 levels, called m0 (0 g/pot), m1 (10 g/pot), and m2 (20 g/pot). There were 12 treatment combinations that were repeated 3 times in order to obtain 36 experimental units. The results showed that the drought stress treatment had a significant effect on maize plant height at 7 WAP of 174.22 cm, plant dry weight of 86.67 g, root dry weight of 21.67 g, and seed dry weight of 37 g. Drought stress of 40% FC can reduce the growth and yield of maize. The mycorrhizal dose treatment had no significant effect on the growth and yield of maize. The application of mycorrhizal dose of 20 g/pot tends to increase the growth and yield of maize. There was no interaction between drought stress treatment and mycorrhizal dose on growth and yield of maize.

This study was carried out to evaluate the effects of increasing levels of digestible methionine+cystine on performance and carcass composition of high genetic potential barrows for lean deposition. Sixty-four barrows with initial weight of 95.46 ± 1.09 kg were allotted to a completely randomized block design, with four levels of digestible methionine+cystine (0.427, 0.466, 0.504, and 0.545%, corresponding to the digestible methionine+cystine:digestible lysine ratios of 57.0, 62.0, 67.0 and 73.0%, respectively), with eight replicates, and two animals per experimental unit. Experimental diets and water were provided ad libitum until the end of the experimental period when pigs reached 125.21 ± 2.49 kg. Levels of digestible methionine+cystine did not affect daily intake, daily weight gain and feed conversion of the animals, but they affected daily intake of digestible methionine+cystine which increased linearly. Levels of digestible methionine+cystine did not affect carcass weight, meat amount, backfat thickness at P2, and daily meat deposition. The digestible methionine+cystine level of 0.427%, corresponding to the digestible methionine+cystine:lysine ratio of 57.0% and to a daily digestible methionine+cystine intake of 14.20 g/d, provides the best performance and carcass traits for high genetic potential barrows in the phase of 95 to 125 kg.
