Harvest index of lowland rice grown in mine-contaminated soil supplemented with coconut shell and cattle manure biochar. Yield parameters of lowland rice grown in mine-contaminated soil supplemented with coconut shell and cattle manure biochar.
Conclusion and Recommendation
However, application of coconut biochar increased manganese concentration in lowland rice grains. This study showed beneficial effects of biochar on the growth of lowland rice even when grown in mine-contaminated soil.

MORTALITY OF Corcyra cephalonica (STAINTON) LARVAE TREATED WITH Anamirta
Abstract
Introduction
In a study conducted by Dioquino (2002 as cited in Tirado et al., 2008), almost 88% of the 273 cases of insecticide poisoning reported to the National Poison Control and Information Service (NPCIS) were due to intentional exposure. Contamination usually leads to eye, dermatological and respiratory problems (UNEP, 1996 as cited in Tirado et al., 2008).
Materials and Methods
The rice bags were then folded and placed inside a 5.08 x 12.7 x 17.78 cm plastic container. The number of dead larvae was recorded to determine the mortality of rice moth larvae and the effectiveness of A.cocculus seeds through the use of statistical analysis and hypothesis testing.
Results and Discussion
The specimens were in the early larval stage ranging from one to seven days old. Carbaryl inhibits the activity of the enzyme that breaks down acetylcholine, leading to overstimulation of the nervous system, which causes the insects' respiratory muscles to contract (Bond et al., 2016).
Conclusion
Qadir and Muffazer (2012) and Jothivel and Paul (2008) also found that increased exposure leads to higher mortality rates of Mystus vittatus and Clarias batrachus. The comparable effect of the different concentrations of the Lagtang extract and Sevin can be attributed to the picothroxin present in Lagtang and the active ingredient carbaryl of Sevin, which also has similar activity in the nervous system.

EFFECTS OF Hydrolea zeylanica (L.) VAHL AND Pistia Stratiotes (L.) ON RICE
GROWTH AND YIELD
In addition, no reduction was observed in height per plant, number of grains per panicle, percentage of spikelets filled, and 1000-grain weight of DSR at 15 densities. However, there were significant differences in the number of rosettes and leaves per plant (Table 4).
IDENTIFICATION OF POTENTIAL BACTERIAL AND FUNGAL BIOREMEDIATORS IN RICE ECOSYSTEM
CONTAMINATED WITH MINE TAILINGS
Isolated and identified fungi and bacteria can determine the presence of heavy metals such as cadmium and lead in the soil. A large number of microorganisms are able to grow in the presence of high concentrations of heavy metals (Anderson and Cook, 2004).
GROWTH PERFORMANCE AND YIELD OF RICE VARIETY MIXTURES (VARMIX) UNDER SOIL
MOISTURE FLUCTUATION STRESS DURING REPRODUCTIVE STAGE
Among areas challenged by climate change, such as rainfed conditions, the incidence of major pests and diseases is also increased (Haq et al., 2010). The allelopathic effects of different genotypes in VarMix inhibit the pathogen (diseases) and pests' expansion (Finckh et al., 2000).
Results
Scanned images were analyzed for total root length (TRL) and total lateral root length (TLRL) using WinRhizo v. Total root nodal length (TNRL) was calculated as the difference between TRL and TLRL. Mean total root length (TRL), total lateral root length (TLRL), total root nodule length (TNRL), mean root nodule length (MNRL) and branching index (BI) of mono or VarMix cultures under constant water (CWL) and continuous cycles alternating watering and drought (CAWD).
Discussion
Most irrigated lowland cultivars are bred for their high yield potential, pest and disease resistance, and grain quality (Peng and Khush, 2003). This was partially attributed to its plasticity in TLRL under condition indicating a key role of the stage in lateral root branching as a key response to water stress conditions (Suralta et al., 2018). In this study, the presence of NSIC Rc 298 in some VarMixes triggered an increase in mean root plasticity.
CHANGES IN THE TOTAL PHENOLIC CONTENT OF RICE AS INFLUENCED BY YELLOW STEMBORER
Schirpophaga incertulas WALKER) INFESTATION
Phenolic compounds are secondary metabolites that constitute one of the most abundant and widespread groups of substances in plants (Amsagowri et al., 2018). This finding can be attributed to the induced response of the plants when YSB larvae were introduced (Sanchez et al., 2018; Spiteller, 2008) into the leaf sheath where biosynthesis begins and unknown molecules are released. Similar observations were found by Gutbrodt et al. 2011) who noted increased resistance of the plant used as a resistance control after 3-4 days.
Conclusions and Recommendation
Higher amounts of p-coumarin in the kernel could contribute to the overall resistance to stem attack.

BOOSTING THE ENTREPRENEURIAL SKILLS OF FARMERS FOR A SUSTAINABLE COMMUNITY
ENTERPRISE

Acceptability index based on the overall acceptability of the different brews between female (n=13) and male panelists (n=17). During the test marketing of the rice and mung bean concoctions, all packaged products were sold out (Figure 5).
Conclusions and Recommendations
However, their enthusiasm for this community enterprise and the joy brought by the success of the product launch is a manifestation of their latent need for self-actualization and identity recognition in society. 2012) note that among the drivers of women's success in entrepreneurship are social identity, achieving excellence and self-confidence. A study in Malaysia on women-led micro-enterprises found that the most important attribute that positively affects business performance is entrepreneurial alertness, or the ability to spot and take advantage of opportunities in the environment (Mamun and Ekpe, 2016). In addition, involved women can actively inform, encourage and involve other women in the community for opportunities offered by institutions (eg skills training, development projects).
ROOT AND SHOOT GROWTH OF RICE IS ENHANCED BY NITROGEN APPLICATION
FLUCTUATIONS
Nutrient status in the soil is critical for the process of root development (Lopez-Bucio et al., 2003). The SMC in each pot was calculated as the ratio of the water weight (the difference between the wet weights of the soil excluding the bucket on a given day) to the dry weight of the soil (Suralta et al., 2015). Several QTL associated with root plasticity response to limited N have been mapped (Manangkil et al., 2019).
Conclusions

Japan began using combines in the 1970s (Pingali, 2007), which were introduced in the Philippines with modifications (De Padua et al., 2004).

MORPHO-AGRONOMIC CHARACTERIZATION OF SELECT PHILIPPINE TRADITIONAL RICE VARIETIES
A total of 199 traditional rice varieties were collected from different provinces of the Philippines and used in the study. In terms of qualitative traits, some of the traditional Philippine varieties have bare leaves (Table 5). The 199 traditional rice varieties showed variability for most traits, especially for the quantitative traits.
