Abstract

Population growth rates cause an increase in food demand, but the planting area is decreasing due to land-use change. The land available to be utilized by farmers is mostly suboptimal land. The disadvantages of suboptimal land are low pH values ​​(4.7) and a small number of nutrients (Nitrogen = 0.11%, Phosphorus = 0.45 ppm, very low Carbon, very high Aluminum, and medium Cation exchange capacity) and for increasing the value of suboptimal land can be given organic fertilizer such as cattle manure and kieserite. This study aims to determine the effect of cattle manure and kieserite on rice growth with the SRI planting system in suboptimal land. The study was carried out in farmers' paddy fields at Ambacang Market, Kuranji District, Padang from June to October 2019. This experiment uses a completely randomized design (CRD). Data were analyzed by the F test at a 5% significance level. If it is significantly different, it is continued with the Honestly Significant Difference test (HSD) at the 5% significance level. The results showed that the application of cattle manure and kieserite can increase the height of rice plants and the number of tillers.

Abstract

The advancement of agriculture sector in one region cannot be separated from the role of agricultural extension in the region. To cover the deficiency of agricultural extension agents, self-supporting extension agents are recruited from farmers or private parties. This study aims to analyze the role of self-supporting instructors in improving farmer institutions and analyze factors related to the role of self-supporting extension agents in improving farmer institutions. This research was a qualitative descriptive study, and it was conducted in West Pasaman and Sijunjung Regency with a sample of 38 people. The results showed that self-supporting instructors play a significant role in improving farmer institutions; this is seen from 78% of self-supporting extension agents have a role in increasing farmer institutions. Factors related to the role of self-supporting extension agents in improving farmer institutions are (1) the age of agents, (2) the number of partners from farmer groups, and (3) the frequency of training attended by self-supporting extension agents. To increase the role of self-extension extension agents in the institutional development of farmers, it is recommended that institutions who manage the agricultural extension recruit self-supporting extension agents from the millennial generation and facilitate self-supporting extension agents to be able to participate in training related to farming in the agent's area of work.

Abstract

Empowerment activities to improve the ability of coffee farmers in Kerinci Regency are very important to be implemented. The purposes of this study are to describe the empowerment activities undertaken by coffee perfume agroindustry practitioners towards coffee farmers in Kerinci Regency and to explain the empowerment potentials of coffee farmers performed by coffee perfume agroindustry practitioners in Kerinci Regency. This research was designed qualitatively with descriptive methods. Data was collected using a focus group discussion (FGD) method with the informants selected in this study as many as 16 coffee farmers and Kerinci Coffee Perfume entrepreneurs themselves. Data analysis was performed using the Miles and Huberman method. The results showed that the empowerment activities carried out by coffee perfume agroindustry practitioners for coffee farmers in Kerinci Regency were still not available, because kerinci coffee perfume agroindustry practitioners only provided training to coffee farmers working in coffee farms owned by the agroindustry entrepreneurs. Meanwhile, the potential for empowerment of coffee farmers by coffee perfume agro-industry prractitioners in Kerinci Regency is very high, because the characteristics of coffee farmers that have a sense to develop and easily receive information to improve their abilities and skills in producing high quality coffee beans. Based on this, henceforth, this research can be directed at the strategy of empowering coffee farmers in Kerinci Regency by kerinci coffee perfume agro-industry practitioners and the impact of empowerment that has been done.

Abstract

This study was conducted to assess the biocontrol efficacy of arbuscular mycorrhizae fungi (AM Fungi) against stem rot disease caused by Sclerotium rolfsii Sacc. in peanut. The AM Fungi can be associated with almost all types of plants. The purpose of this study was to obtain isolates of arbuscular mycorrhiza fungi (AMF) as a potential biofungisida against Sclerotium rolfsii and can characterize the mechanism of the FMA in controlling S.rolfsii (salicylic acid) on peanut plants. The AM Fungi inoculant (40 spores g-1 in concentration) was introduced to peanut seedling (25 g plant-1 ) at planting time where as Sclerotium rolfsii inoculated 30 days after planting time. The experiment was arranged in the completely randomized design (CRD), which is 7 treatment sand repeated 10 times in the greenhouse experiment. The data were analyzed using analysis of variance (ANOVA) using STAT program 8 and the Tukey test at 5% significance level. The AM Fungi treatments showed significantly redused the percentage of disease severity in infected peanut plants around 34.28% - 57.15% and longer incubation period, respectively. They increased root colonization (20,00 - 46.67%) with a middle to high category. The AM Fungi C isolate (isolated from Solok county), and the A isolate (isolated from Payakumbuh city) were the best as a biocontrol against S rolfsii (57.15%), followed by isolate D (isolated from Padang Pariaman county) 54,30 %. They also increased Salicylic acid content 1,4 times (70.72 ppm) compared to control (49,59 ppm). It can be concluded that the application of AM Fungi as a biocontrol agent played an important role in plant resistance and exhibit greater potential to protect peanut plants against S. rolfsii.

Abstract

This study aims to estimate genetic parameters including genetic diversity coefficient, phenotypic diversity coefficient, heritability value, and the correlation between the character of plants from eight soybean varieties. The research was conducted from August to December 2017, in the Wasafi Village of Prafi District, Manokwari Regency. The study was designed using Randomized Block Design (RBD) with 8 treatments of soybean varieties. Each treatment was repeated 4 times, to obtain 32 experimental units. The data obtained were analyzed using ANOVA and if it had a significant effect, it was further tested using the Duncan Multiple Range Test (DMRT) at the 95% level, through the Costat program. The results of ANOVA analysis were used to obtain Variable Partition values, Genetic Diversity Coefficient (GDC), Phenotype Diversity Coefficient (PDC), and Heritability. Correlations between characters were also analyzed using the Costat program. Estimation results of genetic parameters indicate that the characters selected for selection criteria are based on the value of GDC, PDC, and high heritability are number of branches, number of fertile books, number of filled pods, and number of total pods. The characters that show a positive correlation with the character of the results are plant height, number of trifoliate leaves, harvest age, number of filled pods, number of empty pods, total pods, and number of seeds per plant, while characters that show a negative correlation to a seed weight character are flowering age.

Abstract

The limiting factor affecting the production of sorghum in Indonesia is the rapid decline of sorghum seed vigor and viability. One way of restoring vigor and viability is hydration-dehydration. This study aimed to know that invigoration with the hydration-dehydration method can improve the quality of physiological sorghum seed and to determine the most appropriate conditions to use. This experiment used a completely randomized design (CRD) with 3 treatments and 4 replicates and was conducted at the Laboratory of Seed Science and Technology, Andalas University from January until March 2019. The treatment in these trials are: A = not hydrated-dehydrated seeds (control), B = Hydration for 1 hour and dehydration for 6 hours at the temperature 400C, C = high-quality seeds. The data were analyzed using the F test at the 5% significance level. Significant differences were further analyzed using an Honestly Significant Difference (HSD) test also at the 5% level. The results showed that hydration-dehydration can increase the vigor and viability of sorghum seeds from 56% to 70,5% and 55% to 75%.
