A region’s agricultural sector plays a strategic role in fulfilling its food needs with ideal nutrition. The potential of cereal commodities, specifically rice and corn, was identified based on the production level and competitiveness by district in Buleleng Regency, Indonesia. The regency’s potential to provide and support food security was also determined through a quantitative descriptive analysis of the Location Quotient (LQ), Shift Share Analysis (SSA), Localization Coefficients, and Levels of Food Availability by utilizing secondary data on cereal commodity production and population numbers over the course of 10 yr (2012–2021). Results showed that Sawan, Seririt, and Sukasada districts were …
Disease-Reducing Effect Of Calcium Salts Against Postharvest Diseases Of Mango (Mangifera Indica L. Cv. Carabao) Fruits, Melissa P. Montecalvo, Mary Joy C. Mendoza, Teresita U. Dalisay
Disease-Reducing Effect Of Calcium Salts Against Postharvest Diseases Of Mango (Mangifera Indica L. Cv. Carabao) Fruits, Melissa P. Montecalvo, Mary Joy C. Mendoza, Teresita U. Dalisay
The Philippine Agricultural Scientist
Mango fruits (Mangifera indica L. cv. Carabao) are susceptible to fungal infection, resulting in postharvest diseases. Chemical pesticides are used for disease management but may have a health impact and are costly. Therefore, alternatives to chemical control are necessary to minimize health risks and losses due to postharvest diseases. This research presented the disease-reducing effect of calcium salts, calcium chloride (CaCl2) and calcium carbonate (CaCO3), against mango stem end rot (SER) (sometimes caused by Lasiodiplodia theobromae) and anthracnose (caused by Colletotrichum gloeosporioides sensu lato). In in vitro assays, mycelial growth of both pathogens …

Problems facing farmers practicing conservation agriculture in the semi-arid zone of Tunisia include appropriate cover crop selection, management of allelopathic effects affecting subsequent crop performance, and influence of seasonal variation on allelopathy expression. Allelopathy expressed by faba bean (Vicia faba L.) toward durum wheat [Triticum turgidum ssp. durum (Desf.) Husn.] was studied using bioassays during three growing seasons. The role of phenols in the expression of such potential was also investigated. Analyses of plant samples at three phenological stages (flowering, fruiting, senescence) revealed that leaves were most inhibitory. Allelopathic potential differed among plant components and phenological stages, with …

Accelerated coleoptile elongation in flooded soils allowed seedling shoots to reach the water surface to maintain gas exchange and CO2 fixation. Rice genotypes with tolerance of flooding during germination (anaerobic germination, AG) exhibited fast coleoptile elongation as an escape mechanism. On the other hand, tolerance of complete submergence during the vegetative stage, conferred by SUB1A, involved growth retardation to conserve energy for maintenance metabolism, with resumption of growth upon de-submergence. Combining genes controlling flood tolerance at these two stages with contrasting mechanisms was necessary in flood-prone areas for protection during germination under direct seeding and during vegetative stage. …

Sustainability of the transplanted and flooded rice system is threatened by water and labor availability in many Asian countries including the Philippines. Dry direct seeding instead of transplanting is evolving as a viable crop establishment option to deal with labor and water shortages. Two experiments from July 2020 to June 2021 were conducted to determine the effect of different seeding rates [20 kg ha-1 (SR20), 40 kg ha-1 (SR40), 60 kg ha-1 (SR60), and 120 kg ha-1 (SR120)] on the growth, grain yield, and yield components of 2 rice varieties that were established through direct seeding …

This paper evaluated the effects of different polishing times and regular cooking on the phytochemical properties and antioxidant activities of black rice Brillante, red rice Minaangan, and white rice NSIC Rc 160. Rice samples were polished for 0, 15, 30, and 45 s, and were cooked using their optimum cooking water ratio. The samples were then characterized for their phytochemical properties [total anthocyanin content (TAC), total phenolic content (TPC), and total flavonoid content (TFC)] and antioxidant activities [DPPH-radical scavenging activity (DPPH-RSA) and ferric reducing antioxidant power (FRAP)]. Pearson’s correlation analysis (PCA) was employed to determine the strength of …

Rice is one of the most valuable staple food crops in the world. However, several challenges greatly affect production, one of which is the threat imposed by heat stress. To address this, researchers are developing varieties that are heat stress tolerant with genetic markers aid. In this study, eight rice genotypes, namely Dular, Nagina 22, NSIC Rc 222, Milyang 23, EL15, EL92, EL85, and IR52 were observed for agromorphic data, which included plant height, panicle length, filled and unfilled grains, and grain yield. Flower samples were collected to determine the effect of heat stress on pollen fertility. Molecular markers were …

Cotton (Gossypium hirsutum L.) is as famous as “White Gold” due to its high quality fiber. Boron (B) is one of essential micronutrients involved directly or indirectly in many plant processes. Cotton growth, yield and quality are intensely influenced with B application. A 2 years field based study was conducted to explore the impact of foliar applied B (0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 kg ha-1) on productivity and quality of cotton cultivars (FH-113, MNH-786, and CIM-496). Outcomes of the experiment reflected that application of various levels of B significantly influences the growth and quality attributes …

Grain yield variations in PSB Rc18, NSIC Rc222 (inbreds) and NSIC Rc202H (hybrid) were determined across growing environments as a function of cropping seasons and locations in rice producing areas in the Philippines. Contribution of location to variation in grain yield is 61.0%, while 12.7% for the season, and 6.1% for the genotype and this must be due location by season by genotype interactions. Dry season cropping in Nueva Ecija produced the highest mean grain yield. On the other hand, wet season cropping in Davao del Sur produced the least mean grain yield. The genotypes differed in their response to …

One of the new strategies to increase the effectiveness of chemical fertilizers, prevent the waste of chemical fertilizers, and increase the yield of agricultural products, is the use of natural compound such as zeolite. This study was conducted to investigate the effects of zeolite (0, 5, 10, and 15 t ha-1) on agronomic and biochemical responses as well as yield components of maize (cv. Simon) under normal (90% field capacity), moderate (75% FC), and severe (60% FC) drought stress conditions during 2017-2019. The results showed that moderate and severe drought stress significantly decreased plant height (10.9% and 19.7%, …
The Role Of Α-Tocopherol In Mitigating The Effect Of Elevated Co2 Concentrations Emitted From The Al-Hunay Power Plant Main Station On Glycine Max L. Plants, Mohammed Abdulrahman Almuwayhi
The Role Of Α-Tocopherol In Mitigating The Effect Of Elevated Co2 Concentrations Emitted From The Al-Hunay Power Plant Main Station On Glycine Max L. Plants, Mohammed Abdulrahman Almuwayhi
The Philippine Agricultural Scientist
Soybean (Glycine max L.), belonging to Leguminosae, is an essential food in Asian countries. It has become a necessity to study the long-term effects of elevated concentrations of CO2 on plant growth and development. Climate change may be affected by the increment of CO2 and higher temperatures on crops. Elevated concentrations of atmospheric CO2 can negatively affect the yield as well as the quality of the field crops. Alpha-tocopherol is the major vitamin E compound found in leaf chloroplasts. This antioxidant deactivates photosynthesis-derived reactive oxygen species and prevents the propagation of lipid peroxidation by scavenging lipid …

The physiological quality of seeds decreases during their storage under unfavourable conditions. These deteriorated seeds exhibit a poorer performance, especially under stress conditions. A factorial experiment was conducted to investigate the effects of H2O2 on the germination of aged pumpkin seeds under drought stress. Hydroprimed seeds and also the seeds pre-treated with 100, 200, and 400 μM H2O2 were exposed to drought (0, -0.2, -0.4, and -0.6 MPa applied using PEG). Under drought conditions, seeds primed with H2O2 showed improved germination percentages and rates, higher vigour index, greater plumule and radicle …
