Abstract

Applying organic fertilizers can improve the physical and biological properties of the soil. One of the organic fertilizers that can be used is chicken manure with the addition of POC vegetable waste. This study aims to determine the effectiveness of applying organic chicken manure and POC vegetable waste on the growth and production of sweet corn (Zea mays Saccharata). This study used a factorial randomized block design (RBD) consisting of 2 factors with 16 combinations and 3 blocks. The first factor is the application of organic chicken manure (A), which consists of 4 levels. 0 g/plot, 700 g/plot, 1400 g/plot, 2100 g/plot. The second factor is the provision of POC of vegetable waste (S) which consists of 4 levels, namely, 0 ml/liter of water/plot, 300 ml/liter of water/plot, 500 ml/liter of water/plot, 700 ml/liter of water/plot.The parameters observed were plant height (cm), number of leaves (strands), cob length (cm), cob diameter (cm) and production weight using klobot per plot (g). The results showed that the application of organic chicken manure had a significant effect on Production weight parameters used husks per plot (g) and had no significant effect on plant height (cm), number of leaves (strands), cob length (cm) and cob diameter (cm).

Abstract

One of the most important stages in the process of transferring in vitro cultured seedlings to their natural environment is the acclimatization stage. The acclimatization stage is a critical period in plant propagation. The factors that most influence the growth of in vitro seedlings in the acclimatization process are suitable planting media and the administration of biostimulants. This study aimed to obtain the best planting medium and type of biostimulant for the growth of black orchid plantlets at the acclimatization stage. The study used a completely randomized design with a factorial pattern with two factors, namely first factor: type of growing media with 5 levels of treatment (wood sawdust, coconut coir, cocopeat, rice husk, sugarcane dregs) and second factor: type of biostimulant (without biostimulants; Moringa oleifera extract; Centella Asiatica extract; and Melastoma malabathricum extract). The results showed that the highest percentage of plantlet survival (100%) in the early stages of acclimatization was shown in plantlets grown on wood sawdust and coconut coir media. At the advanced acclimatization stage, the type of biostimulant significantly affected the parameters of survival percentage, tiller height, average number and width of leaves, and average number and length of roots. Optimal planting medium and biostimulant type for advanced acclimatization orchid growth is a single treatment of wood sawdust media with a tiller survival rate (100%), the highest number of leaves (4.65 strands), most roots (8.4 strands).

Abstract

Using plantation crop residues in the form of oil palm fronds and coconut shells has the potential as a soil ameliorant material such as Biochar. Using Biochar as an ameliorant can improve soil fertility, one of which is peaty soil with a very acidic pH. The research aims to analyze the basic characterization of Biochar palm fronds and coconut shells on the physical properties of peaty soil. Palm fronds and coconut shells were pyrolyzed using a simple combustion device in the form of a pyrolysis drum. Combustion with pyrolysis drums is carried out in a closed manner in the absence of oxygen for 2-5 hours. Parameters observed were lignocellulose of palm fronds and coconut shells, spectrographs, chemical properties of Biochar of palm fronds and coconut shells, and physical properties of peaty soil after applying Biochar of palm fronds and coconut shells. The pH, total C, total N, C/N, total P, available P, total K, total Na, and the volume and pore size of the coconut shell biochar showed higher results than the palm frond biochar. However, the results of the analysis of total Mg, total Ca, CEC and ash content and surface area on palm frond biochar showed higher results than coconut shell biochar. The moisture content and BD values of peaty soil in applying coconut shell Biochar showed the best results compared to palm frond biochar.

Abstract

Red onion is a strategic commodity because it is one of the horticultural products required for household consumption, the culinary industry, and medicinal purposes. The Kampar Regency is known for producing river fish, which the residents of Kampar and Pekanbaru consume. If this refuse is not correctly managed, it can pollute the environment. This refuse can be converted into liquid organic fertilizer (POC) due to its ability to improve soil fertility and shallot plant growth. This study aimed to determine the effect of interaction and the primary optimization of the growth and yield of shallots on ultisol soil by administering POC derived from the fish refuse of the Kampar River. The investigation was conducted in the experimental garden of the Riau Islamic University, Pekanbaru, Faculty of Agriculture. The research employed a wholly random design with two factors. The first factor consisted of four levels of concentration of river fish waste (0, 22,5, 45, 67.5, and 90 ml-1) and the second factor consisted of four levels of frequency of river fish waste (1, 2, 3, 4 times). The data were analyzed and the BNJ Advanced Test was administered at a 5% confidence level. The results indicated that the interaction and main effects were significant for plant height, number of leaves, age of tuber formation, number of tubers, wet tuber weight and dried tuber weight, with the optimal treatment consisting of 67.5 – 90 ml-1 applied three to four times.

Abstract

Sunflower (Helianthus annuus L) is one of the best sources of vegetable oil because of the high quality of the oil. This plant is a leading commodity that has the potential to be developed because, from an economic point of view, it has various benefits as a food ingredient, raw material industry, raw materials, and medicines raw materials for beauty products. Today's sunflower development is more diverted to marginal lands. One of them is the use of coastal areas, which have various economic and technical problems. For this reason, it is necessary to implement innovations that can support sunflower cultivation in coastal areas. One of them is by applying mycorrhiza and adding chicken manure. This study aims to determine the effect of mycorrhiza and chicken manure doses on sunflower yields in coastal areas. This research was conducted using a randomized block design consisting of two factors: mycorrhiza and chicken manure, which were repeated three times. The results showed that mycorrhiza and chicken manure could increase the components of several characteristics and sunflower yields in coastal areas.

Abstract

The decline in national soy output results from a decline in planted area. Optimizing ultisol land is one of the efforts undertaken to increase national soybean production. This study seeks to examine the effect of composting empty palm oil bunches on the growth and yield of soybeans using multivariate tests and principal component analysis during the compost's incubation period. The application of compost and empty palm fruit clusters was able to chelate Al-DD and increase the soil's available P and K. There is a positive Pearson correlation between pH, Ca, K, and Mg, as well as a positive Pearson correlation between all observed growth and development parameters of soybean plants. Pearson's correlation demonstrates the relationship between the characteristics of plant height, number of leaves, number of branches, number of pods, age of blossoming, age of harvest, and productivity. Positive correlations are observed for each parameter observed.
