“…Water consumption by a labour was estimated at 0.1761 m 3 per day (Santosa et al, 2018b), considering the working time as 8 hours per day. In cases where the working hour was less than a day, the amount of water consumption was accumulated and converted into the working day (WD).…”

“…WFblue estimates water consumption from groundwater, while WFgrey estimates the water required for diluting pollutants, including fertilizers, pesticides, and other waste materials. Thus, efforts to reduce water usage in agricultural production for irrigation, minimize the use of pollutants, and improve tree productivity will contribute to WF reduction (Santosa et al, 2018b). This study evaluates the WF of different propagation methods by considering the total water used for a hectare of established trees with the objective of developing a sustainable cocoa nursery production protocol.…”

The nursery phase plays a crucial role in rejuvenating cocoa plantations as it significantly impacts the quality and productivity of the mature trees in the field. However, despite its significance, there remains a lack of understanding regarding its contribution to the water footprint (WF) in cocoa production. This study aims to assess the WF of various propagation techniques to promote sustainable nursery practices. Data on nurseries were collected at the Indonesian Coffee and Cocoa Research Institute in Jember, East Java, Indonesia, from June 2017 to January 2018. The results revealed that propagation accounted for a total WF ranging from 74.28 to 319.41 m3.ha-1 of established cocoa trees, with an average of 186.68 m3. This total WF consisted of 9.02 to 12.89 m3 (7.69%) attributed to seed production and 61.39 to 283.34 m3 (92.30%) attributed to the nursery phase. Among the different nursery techniques studied, the production of true seedlings exhibited the lowest WF, followed by side grafting. To optimize cocoa rejuvenation and minimize WF, it is crucial to carefully select the appropriate nursery technique. Further evaluation is necessary to explore the potential benefits of implementing precision irrigation techniques to reduce WF during the nursery phase. By focusing on sustainable nursery practices, we can enhance the overall sustainability of cocoa production.

“…The study was conducted on three plots of upland rice and three plots of paddy fields, with five sample points taken for each rice plot to represent the number of samples from the observed plot area. Observation of weed propagules is carried out by taking soil samples as much as 2 kg using PVC pipe 11 cm in diameter at a depth of 15 cm because weed propagules on agricultural land are generally 12-16 cm below the soil surface [30]. Soil sampling was carried out in a regular random manner.…”

Weeds can reduce rice yields by 20-89%, mainly due to competition for nutrients, water, sunlight, and growing space. Weeds that grow in rice fields come from propagules previously in the soil. Seedlings are formed from the previous season, so the cultivation system greatly affects them. This study aims to determine the diversity and population of weed propagules in upland rice and lowland rice. This research was conducted by survey method in Semanu District, Gunungkidul Regency, Special Region of Yogyakarta, by taking soil samples from three plots of upland rice and lowland rice paddy. Soil sampling was conducted four times before tillage, 3, 6, and 9 weeks after planting. The results showed that the diversity of weed propagules in upland rice was higher than in lowland rice fields with more weed propagule species. Annual terrestrial weed propagules dominate in upland rice, while in lowland rice fields, it is dominated by annual aquatic weed propagules. The diversity index of weed propagules in upland rice and rice paddy is included in the medium criteria. The number of species and individual propagule weeds in upland rice is more than in the upland rice fields. The results of this study can be used as a basis for proper weed management so that it does not disturb and harm rice plants.

ABSTRACT Cover crops have the same role as biomulches to maintain soil moisture and reduce the evaporation of soil water. The objective of research was to compare Arachis pintoi versus other cover crops as biomulch in immature oil palm plantations. The study was conducted in the Field of Education and Research Palm IPB-Cargill, Jonggol, Bogor starting in December 2014 until May 2015. The experiment was designed according to a randomized block design with four replications. The treatments were cover crop species (biomulch) i.e. no biomulch/natural vegetation, Arachis pintoi Karp. & Greg., Centrosema pubescens Benth., Calopogonium mucunoides L. and Pueraria javanica Benth. Planting materials used were cutings of A. pintoi and seed of C. pubescens, C. mucunoides and P. javanica. The planting material were planted in plots 9 m x 3 m and plot for biomass 1 m x 1 m. The results showed that the A. pintoi was not significantly different from other biomulches for ground covering and capability to hold water. Soil water content in the treatment of A. pintoi biomulch was not different from other biomulch treatments. Keywords: biomass production, cover ground, soil depth, soil water content
