Abstract

Dendrobium orchids are popular plants with high economical value and high demands among the society. The poor quality of orchids is something that can be detected from the cultivation method, including its fertilization. This research aims to discover the impact of the AB mix combination and various types of POC, determine the best type of AB mix combination and POC, and examine the comparison of the AB mix fertilizer combination and types of POC with control fertilizer (AB mix). This research used a Completely Randomized Design (CRD) with a single factor consisting of 5 treatments + 1 control, which are 3 mL/L AB mix plus 150 mL/L POC rice washing excess water, coconut water, kepok banana peel, rabbit urine, cow urine. and control (AB mix). Observation parameters include plant height, stem diameter, number of leaves, number of tillers, length of tillers, and number of roots. Observations were analyzed using Variety Printing at the level of 5% and tested further with the Orthogonal Contrast Test and DMRT at the 5% level. From this research was obtained that the AB mix and POC combination had a significant effect on leaf number parameters. The combination of AB mix and POC rabbit urine was best for the growth of Dendrobium orchids in terms of plant height, number of leaves, leaf length, number of tillers, length of tillers and number of roots. The combination of AB mix and POC was better in terms of leaf number parameters than the control (AB mix)

Abstract

Biofortified rice has emerged as one of the most promising strategies to enhance the micronutrient content of staple crops, offering a practical pathway to reduce stunting and improve nutritional security. In response to the challenges posed by climate change, water scarcity, and the need for more efficient production systems, this study examined the effects of water- and crop- management technologies on the physiological performance and yield of biofortified rice. A factorial randomized complete block design compared continuous flooding and alternate wetting and drying (AWD) irrigation with two crop management systems: conventional and a new technology. The AWD system enhanced photosynthesis without significantly affecting transpiration or stomatal conductance, indicating improved carbon assimilation and more efficient water use. Both AWD and the new technology individually increased dry grain yield per clump, while their combination produced heavier grains, higher productivity, greater 1000-grain weight, and improved water-use efficiency compared with other treatments. Although yield differences were not statistically significant, the consistent upward trends indicate synergistic potential when nutrient management is optimized. Overall, integrating AWD irrigation with new technology crop management can enhance resource efficiency in biofortified rice cultivation while maintaining yield stability under water- limited conditions.
