Abstract

Soil mesofauna plays a role in fertilizing the soil and plants. Soil mesofauna is one of the soil organisms that can provide information about soil quality and fertility. This study aims to analyze the population density of soil mesofauna in secondary forests, oil palm agroforestry with agarwood and community rubber plantations in Kampar Regency. Soil sampling using purposive sampling method and soil mesofauna sorting using a barless tullgreen tool. The results showed that the total population density of soil mesofauna in oil palm agroforestry with agarwood was 102.67 indv/m2, rubber plantations were 96.00 indv/m2, and the secondary forest was 85.33 indv/m2. The soil mesofauna family that was primarily obtained in the secondary forest was the Hahniidae family (21 individuals), the oil palm agroforestry with agarwood was the Formicidae family (35 individuals) and in the rubber plantations, the Formicidae family (20 individuals). Information on the population density of soil mesofauna in secondary forests, oil palm agroforestry with agarwood and rubber plantations in Kampar Regency becomes data for better environmental management.

Abstract

Peat as agricultural land has various obstacles, one of the problems is the decrease in groundwater level. This can have an impact on the availability of nutrients in the soil. Therefore, water management is an absolute necessity for agricultural activities on peatlands. Another effort that can be made to increase the fertility of peatlands as agricultural land is to use organic mulch. This study aims to analyze the effect of peat water level and application of organic mulch on the chemical properties of peat soil planted with corn. This research was conducted in Air Terbit Village, Riau Province and the Soil Laboratory, Faculty of Agriculture, University of Riau, from February to July 2021. This research used a factorial complete randomized design (CRD) method consisting of 2 factors. The first factor was the various heights of the groundwater level which consisted of 3 levels (30 cm, 40 cm and 50 cm), while the second factor was various types of organic mulch (without mulch, mulch of empty oil palm bunches, mulch of rice straw and mulch of corn stover). The results showed that the GWL 30 cm treatment and rice straw mulch increased the pH, Ca and Mg values ​​better than the other treatments, the N element also increased at GWL 30 cm. In general, the two treatment factors also increased the values ​​of P, CEC and Na in some experimental units. C-organic and K values ​​decreased after the treatment compared to the criteria of the soil before treatment.

Abstract

Peanut (Arachis hypogaea L.) is an important food commodity in Indonesia. The low production of peanuts in Riau Province has not been able to meet the people's need for peanuts. According to the Riau Province Food Crops Service (2022) the need for peanuts in Riau Province in 2019 is 8,516 tons, in 2020 the need for peanuts is 7,390 tons, and in 2021 the need for peanuts is 6,474 tons. This study aims to determine the effect and interaction between tillage and the application of fish waste liquid organic fertilizer (POC) and the single factor of both the growth and production of peanut plants and to get the best combination. The research was conducted using a split-plot design. The first factor as the main plot is tillage consisting of three levels, namely without tillage, minimum tillage, and maximum tillage. The second factor as a subplot was POC concentration consisting of four levels, without POC fish waste, 25% POC fish waste (250 ml POC + 750 ml water), 50% POC fish waste (500 ml POC + 500 ml water), and 50 % POC waste fish 75% (POC 750 ml + water 250 ml). Parameters observed included plant height, number of primary branches, flowering age, harvest age, number of pods, number of filled pods, seed production per plant, and weight of 100 seeds. The data obtained were analyzed statistically using analysis of variance and continued with Duncan's multiple range test at the 5% level using the SAS application. The results showed that the interaction of tillage and POC fish waste affected increasing plant height, number of primary branches, number of pods, number of filled pods, seed production per plant, and weight of 100 seeds.

Abstract

This research was conducted to determine the relationship between seed developmental characteristics and yield components in a population of maize (Zea mays L.) grown at different potassium fertilizer rates. The information could be utilized as alternative selection criteria for maize genotypes with high-yielding potential. This research was conducted at the Experimental field of the Horticulture Seed Agency, Pekanbaru. Seven maize genotypes with four potassium fertilizer rates were grown in a 350 cm x 200 cm experimental plot with three replications. The genotypes used were Bisi 228. Pertiwi 3. Bisi 2. Decoral, Bisi 18. Betras 4. and Srikandi. Potassium fertilizer rates included 30 kg, 50 kg, 70 kg, and 90 kg per ha, respectively. Traits observed were plant height, tesseling flowering date, silking date, seed dry accumulation rate, effective seed filling period, cob length, cob weight, number of seed rows, number of seeds per cob, seed weight per cob, the weight of 100 seeds and seed yield per m2. Analysis of variance was performed to the data using SAS and further tested by honesty significant difference at 5% level. Variance component, heritability, genetic correlation coefficient, and selection response were calculated for all characters and effective seed filling duration. The results indicated that the genetic variance component was significant for all characters except for the dry matter accumulation rate. All characters' heritability values were quite high except for effective seed-filling duration and the number of seeds per cob. Phenotypic correlation coefficients were positively significant between seed yield per m2 and plant height, seed development rate, cob length, ear weight, number of seeds per ear, seed weight per ear, and weight of 100 seeds. The genetic correlations was significant between seed yield per m2 and plant height, seed development rate, number of seeds per ear, and seed weight per ear. All characters' direct selection response value is higher than the indirect selection response value.

Abstract

Moringa is a superior plant that has been widely developed in Indonesia. One of the obstacles found in the moringa nursery is the attack of snail pests (Achatina fulica Fer.). Pest control which is currently mostly carried out using synthetic chemical pesticides can have a negative impact on the environment. Therefore, an alternative pest control is needed, namely using vegetable pesticides from forest betel nut (Piper aduncum Linn.). This study aims to obtain the effective concentration of betel nut extract in controlling snails. The research was conducted at the Experimental Garden Technical Implementation Unit, Faculty of Agriculture, University of Riau. The research was conducted in January 2023 - May 2023. Testing the frequency of spraying forest betel leaf extract against snail pests, used a completely randomized design (CRD) with 4 treatments and 4 replications to obtain 16 experimental units. The treatment was without spraying forest betel extract, spraying intervals of forest betel extract 1 × 1 week, 1 × 2 weeks and 1 × 3 weeks. Based on the observations, spraying forest betel leaf extract once a week is the best frequency because it can cause 100% mortality with an initial death time of 18.75 hours after application, Lethal Time 50 191.25 hours after application, and an attack intensity of 4.35%.
