The effect of améliorant kind and its application time on soybean growth in tidal land soil
Authors: Sagala D , Suzanna E , Prihanani  
Published: July 2021

Abstract
Tidal swampland is one type of suboptimal land that can be developed to increase food crop production in Indonesia. However, tidal land contains a lot of Al3+ because it has acid soil reactions. Previous research found that the critical period for soybean plants against Al3+ stress was at the beginning of growth until 20 days after planting. This study aims to obtain the appropriate ameliorant to overcome Al3+ stress during the critical period of soybean growth. An experiment on the types of ameliorant and the application time was arranged in a randomized block design repeated three times. The kinds of ameliorant tested were no ameliorant, dolomite, husk charcoal, husk ash, and straw. Each ameliorant was given 2 tonnes ha−1 before planting in dry cultivation (DC), before planting in saturated soil culture (SSC), 10 days after planting (DAP) on DC, 10 DAP for SSC, 20 DAP on DC, and 20 DAP on SSC. The experiment results are consistent with studies of saturated soil culture, which show that soybean in water-saturated culture has better growth than dry cultivation. In all kinds of ameliorant and at all times, saturated soil culture had more effect on the growth and production of soybeans. The kind of ameliorant only affected the number of branches, and the highest number of branches was obtained in soybean treated with dolomite ameliorant. However, it was not significantly different from other ameliorants.

Abstract
One of the technological innovations to increase rice productivity is the Jajar Legowo (double row) planting method. The research aimed to examine the technology of planting Jajar Legowo rice in two ways: manual and transplanter machines in freshwater rice fields. The research was conducted on 6 ha of freshwater rice fields in Martapura Barat, Banjar Regency and involved six cooperator farmers. The superior varieties used were Inpari-30 and Inpari-32. The results show that the average grain yield was higher with transplanter (8.10 t ha−1 GKP), compared to manual planting (6.90 t ha−1). Grain yields planted with transplanter + manure increased grain yields by 1.2 t ha−1 (increased by 17.4%). The transplanter treatment provided an income of IDR20,401,500.- and R C−1 = 2.70 higher than manual row planting (income IDR16,959,500.- R C−1 = 2.59). Transplanters also reduce labour costs for planting (IDR750, 000.- per hectare), and reduce planting times.

Abstract
Livestock is an agricultural sub-sector that contributes sufficiently to the needs of protein. One of the bio reproduction technologies to support livestock productivity is sexing technology. The purpose of this study was to measure the viability and abnormality of sexed spermatozoa from sexing with albumin with the treatment of diluents and antioxidants. The material used in this study was fresh semen of 5 PO bulls with progressive motility >70%. The sexing methodology used is 5%, 10%, and 15% albumin (egg white) gradients. The diluent treatment used was CEP-2 and andromed, with the addition or without the 1mM antioxidant (glutation). The sexed semen was made in liquid semen and stored at 3-5 ° C. Sample preparation was done by making a smear of spermatozoa on glass objects and colored with eosin negrosin. Viability and abnormality analysis was performed on days 0 (H0) and 5 (H5). Viability and abnormality analysis of spermatozoa using SCA v.2.1. Parameters measured included: spermatozoa viability and abnormality. The design of the experiment used a 2×2 factorial pattern. Data analyzed with SPSS 24. The viability of spermatozoa from sexing using egg white albumin in andromed diluents is better than CEP-2 on storage days 0-2. Abnormalities of spermatozoa of sexing during cold storage were not influenced by diluents (CEP-2 and andromed) or the use of glutathione. The viability of spermatozoa during cold storage (>80%) and abnormalities (<20%) indicate the quality of liquid semen results from sex is still good.

Abstract
Rhizhosphere and phyllosphere serve as habitat for many kinds of plant-associated mikrobial. This study aims to determine the effect of application of microbial consortium in the rhizosphere and phyllosphere of clove seedlings on the plant physiological parameters. The study was conducted as a factorial experiment with two factors based on the randomized blocked design. Application of microbial consortium of Azotobacter sp., Lactobacillus sp., Bacillus subtilis, and Trichoderma sp. in the rhizosphere was set as the first factor, consisted of four levels, namely control (0 mL), 4, 6, and 8 mL. The second factor was the application of the microbial consortium of Gliocladium sp. and Beauveria bassiana in the phyllosphere consisted of four levels, namely control (0 mL), 2, 4, and 6 mL. The physiological parameters observed included observations on the components of leaf stomata, light intensity, and leaf chlorophyll. The resuls show that the best microbial consortium treatment that gave better physiological response of the clove seedlings was 8mL/plant in the plant rhizosphere, and 6mL/plant in the plant phyllosphere. However, there were no significant difference on the effect of the application of these microbial consortiums in the rhizosphere and the phyllosphere applied simultaneously compared to controls, meaning that the treatment application was 8mL/plant or 6mL/plants. Some influence directly and indirectly from the microbial consortium both in the rhizosphere and the phyllosphere was on the physiological parameters of the light and leaf chlorophyll components, but not significant for the stomata component.

Published: July 2021

Abstract
Mineral ash fertilizer resulting from a burning process of plant wastes has the potential to replace or reduce the use of anorganic potassium fertilizers. Hence it can increase the availability of potassium for plants. This study aimed to determine the effect of ashing temperature on potassium nutrient content from kapok peels, banana stems, and coconut husks. The combustion temperature treatments were 300° C and 600°C for 3 hours into the muffle furnace and without ashing. Analysis of potassium content was conducted using the Atomic Absorption Spectrophotometer (AAS) method. The results showed that the temperature of 600°C gave the highest content of potassium from kapok peel (9.59%), the temperature of 300°C for banana stem (9.82%), while without ashing, the highest content of potassium was from the banana stem (8.20%). The organic matter that produces the highest potassium content was banana stem at an ashing temperature of 300°C, and the lowest was coconut husk at an ashing temperature of 600 °C.

Abstract
The development of drought rice screening is one of the keys to increase selection effectiveness. This development can be done by developing the analytical method. In general, identification of tolerant rice can be conducted with the cluster analysis. However, the common cluster analysis just was focused on genotype clusters so that the reason for the clustering does not can explain. Therefore, the other analysis approach needs to be done, such as cluster heatmap analysis. The objective of this study is to identify the effectiveness of cluster heatmap used in rice tolerance screening under drought stress. This study was designed with a nested randomized complete group design, where replications were nested in PEG 6000 concentration as a screening environment. The concentration of PEG used in this study was 0% PEG and 20% PEG. The genotype used consisted of 8 genotypes repeated three times. Hydroponic culture used ABmix in culture solution. As for, the number of characters observed was seven morphology characters and three physiological characters. The results of this study showed that cluster heatmap analysis could distinguish between the rice tolerant group drought-tolerant variety control (Salumpikit, Pokkali, and Inpari 29), and sensitive variety control (IR 20). Besides that, the good selection characters in hydroponic drought screening were shoot length, the number of tillers, shoot fresh weight, root fresh weight, and total biomass fresh weight. Based on this study, the cluster heatmap can be recommended as one of the analytical methods in hydroponic drought screening.
