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 Rice Genotypes Under Different Growing Environments In The Philippines, Kim Nyka C. Perdiguerra, Shiro Mitsuya, Akira Yamauchi, Felino P. Lansigan, Maria Victoria O. Espaldon, Jose E. Hernandez, Pompe C. Sta. Cruz Jun 2021

Grain Yield Variations In Rice Genotypes Under Different Growing Environments In The Philippines, Kim Nyka C. Perdiguerra, Shiro Mitsuya, Akira Yamauchi, Felino P. Lansigan, Maria Victoria O. Espaldon, Jose E. Hernandez, Pompe C. Sta. Cruz

The Philippine Agricultural Scientist

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 …


Effects Of Zeolite On Agronomic And Biochemical Traits And Yield Components Of Zea Mays L. Cv Simone Under Drought Stress Condition, Mehri Salehi, Mahdi Zare, Forood Bazrafshan, Ahmad Aien, Bahram Amiri Jun 2021

Effects Of Zeolite On Agronomic And Biochemical Traits And Yield Components Of Zea Mays L. Cv Simone Under Drought Stress Condition, Mehri Salehi, Mahdi Zare, Forood Bazrafshan, Ahmad Aien, Bahram Amiri

The Philippine Agricultural Scientist

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 Mar 2021

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 …


Effect Of Hydrogen Peroxide On Physiological Quality And Germination Of Aged Pumpkin Seeds Under Drought Stress Condition [Research Note], Hossein Reza Rouhi, Mohammad Hasan Vafaei, Maryam Saman, Ali Abbasi Surki Mar 2021

Effect Of Hydrogen Peroxide On Physiological Quality And Germination Of Aged Pumpkin Seeds Under Drought Stress Condition [Research Note], Hossein Reza Rouhi, Mohammad Hasan Vafaei, Maryam Saman, Ali Abbasi Surki

The Philippine Agricultural Scientist

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 …
