Dracaena ‘Sun Beam’ (NSIC 2014 Or 85) is a chlorophyll mutant of D. braunii developed by gamma irradiation (Cobalt-60 source) of 15-cm stem cuttings and registered by the DOST-PNRI with the National Seed Industry Council of the Bureau of Plant Industry, Department of Agriculture (DA-BPI-NSIC) and to the Mutant Variety Database of the Joint Food and Agriculture Organization of the United Nations / International Atomic Energy Agency (FAO/IAEA) Program. In all aspects, D. ‘Sun Beam’ is similar to the parent material except for the shorter leaf and its broad bar. The propagation of the mutant is true-to-type by cutting (top cutting, stem cutting, and nodal cutting) and separation of suckers. D. ‘Sun Beam’ is very attractive and shoots or top cuttings may be used as cut foliage in flower arrangements or grown individually or in a group as containerized plants, materials for terrariums, dish gardens, and landscaping.

In May 2021, we have serendipitously recollected the species in Gingoog City, Misamis Oriental, extending its distributional range northward of Mindanao island. Here, we provide a detailed description of H. josetteae based on our recent collection, comparison with its allied species, color photographs to aid easy identification, updated geographical distribution information, ecology, phenology, and an IUCN conservation assessment.

During the wet season (Sep–Dec 2017), the combination of RMKC and inoculant gave the highest yield advantage of 33.5% and 99.7% over the Farmer’s Practice for Ilocos Pink (3,113.33 kg/ha) and Namnama 2 (2,176.70 kg/ha), respectively. For the dry season (Jan–Apr 2018), a similar trend was observed. The combination of RMKC and inoculant resulted in a yield increase of 41.9% and 55.6% for Ilocos Pink (1,790 kg/ha) and Namnama 2 (1,690 kg/ha), respectively. The increase in weight of pods per plot and 100-seed weight, which contributed to higher yield could be attributed to the plant growth-promoting effect of RMKC that has been analyzed to contain significant amounts of micro-nutrients and gibberellic acid (GA3). Thus, Carrageenan PGP as RMKC should ...

The statistical design of the field trial was a Randomized Complete Block Design (RCBD) with four replicates per treatment per experiment. The CLS and rust infections were significantly reduced with the application of 150ppm PGP by 15.2% and 36.2%, respectively. The BPI Pn 9 peanut variety applied with PGP consistently and significantly had higher pod yield up to 2.14 t/ha and seed yield of 1.63 t/ha with a corresponding 37.6% and 34.5% increase, respectively. At least Php45,771 per hectare additional income was realized from the application of PGP with a maximum MBCR of 12.3%. For Farmer’s peanut variety, significant increase of 23.6% on pod yield and 36.5% on seed yield were obtained resulting to an additional income of Php 18,400/ha up to 37,800/ha with an MBC...
