Abstract

Tea nursery that commonly uses planting media that consist of 30% of subsoil and 70% of topsoil needs more additional planting media to improve growth. It has been reported that black tea factory waste (tea fluff) can be used as compost for planting medium of tea nursery. This research was conducted to apply tea fluff as an alternative planting medium for tea seedling at the tea nursery of Research Institute for Tea and Chincona. GMB7 clone was used as a tea plant. Ten treatments, i.e. 100% topsoil (negative control), subsoil and topsoil with a combination of 30:70% (positive control), 40:60% and 50:50%, and subsoil or topsoil mixed with tea fluff compost with a combination of 70:30%, 60:40% and 50:50%, were arranged in a randomized block design with three replications. The results showed that plant height and root dry weight increased with the application of 30-40% tea fluff compost on topsoil. The number of leaves increased in all treatments, the length of the roots increased with 30-50% tea fluff compost on the subsoil, and the percentage of live seeds decreased compared to positive controls. Therefore, tea fluff compost can be used as an alternative medium for tea seedlings by mixing it up to 40% on topsoil, and up to 50% on subsoil in a combination of 70% of topsoil and 30% of subsoil without mixing.

Abstract

Fertilizers and pesticides application in the agricultural sector provide a significant benefit in agricultural production. However, the use of fertilizers and pesticides continuously can be a harmful effect on the condition of the agricultural environment and the living things around it. Heavy metal pollution from the use of fertilizers and pesticides can cause health problems in humans, animals, and soil. Nickel is a dangerous heavy metal. The purpose of this study was to obtain the value of nickel-metal quality standards in two types of soil texture with rice as an indicator plant. This nickel quality standard testing activity was carried out in 2018 at the Indonesian Agricultural Environment Research Institute. Light textured soil was obtained from Bantul and heavy textured soil from Lamongan and Ngawi. Soil samples were tested for the adsorption of heavy metals using the Langmuir approach. A pot experiment was conducted at the screen house for heavy metals calibration in the soil. The results of the regression of the nickel content in the soil and rice can be seen as the quality standard value. Estimated quality standards in light-textured soils (Bantul) was 1.388 mg kg-1, heavy-textured soils (Lamongan and Ngawi) was 1.855 mg kg-1 and 1.697 mg kg-1, respectively. The value of nickel-metal quality standards in the clayey soils are higher than those in the light-textured soils

Abstract

The increasing of Indonesian population has led to a decrease in the area of rice fields in Indonesia. Therefore, it is needed to increase the fertility and the productivity of paddy soil. Since 1984, several attempts have been made to increase the productivity of paddy soils through the green revolution program, but this has had a negative effect on the fertility of paddy soils. The exploitation of paddy soil layers which has been increasing for years has decreased paddy soil. Other aspects of paddy soil management need to be done; one of them is a mixture of top soil layer with plow pan layer. The mixture of top soil layer with the plow pan layer is expected to improve the soil fertility. This research was conducted with the aim to study the effect of the top soil layer and plow pan layer on the chemical properties of paddy soil. This study used a completely randomized design with five treatments of mixing paddy soil layers and three replications. The treatments were A1 = 100% top soil layer, A2 = 75% top soil layer + 25% plow pan layer, A3 = 50% top soil layer + 50% plow pan layer, A4 = 25% top soil layer + 75% plow pan layer, and A5 = 100% plow pan layer. The results showed that the A2 treatment gave changes in optimal soil chemical properties. The A2 treatment decreased EH value to 133 mV, increased pH to 6.08, organic-C 2.22%, total N 0.30%, available P 27.94%, CEC 38.50%, exchangeable Ca 0.88 me 100g-1, exchangeable Mg 0.37%, exchangeable K 0.94% and exchangeable Nadd 0.17%.

Abstract

Purwodadi Botanical Garden is a botanical garden that specifically designated to ex situ plant conservation with typical habitats of low lands and dry areas. In an effort to protect and maintain the collection of plants, one of the things that must be carried out is the monitoring of plant pests and diseases. The research aimed to find out the plant pests and diseases that infect in plant collections at Vak I-V in Purwodadi Botanical Gardens. The method used was a descriptive observation and literature study, while the secondary data were books and environmental maps. There were nine types of pests and nine types of diseases. Pests and diseases are dominated by Leaf Spot Disease, Black Ants, Red Ants, and Lawana candida. They attack some plants, such as from family of Sapotaceae, Sterculiaceae, Mimosaceae, Moraceae, etc. The results of this study can be used as a material consideration in efforts to prevent and increase ex-situ conservation in the Purwodadi Botanical Garden.

Abstract

The availability of nutrients plays a role in increasing crop productivity, especially primary macronutrients (nitrogen, phosphorus and potassium). This research aimed to measure the content of macronutrients and crop productivity in the rice field and to map the nutrients status. The study was conducted from July to October 2019 in Turen District. The survey method based on the boundary of the land mapping unit was used to collect field data in this study. The mapping of nutrient status created using IDW, which was interpolated data based on the assumption that values of unsampled points can be predicted as the weighted average of known values within the neighbourhood. The results showed that the nitrogen status are very low to low status (0.08% - 0.18%), the phosphorus status are very low to low status (4.5 mg kg-1 – 12.37 mg kg-1) and the potassium status are at low, moderate to high status (0.25 cmol kg-1 – 0.71 cmol kg-1). The availability of nitrogen nutrient is classified as S2, the availability of phosphorus nutrient is classified as S3, and the availability of potassium nutrient is classified as S1. The availability of nitrogen, phosphorus and potassium can be increased through fertilization in accordance with the needs and recommendations. The effect of the status of nitrogen, phosphorus and potassium at the end of planting on crop productivity was indicated by the regression coefficient of R2 = 0.0826.
