The lanzones scale insect, Unaspis mabilis Lit and Barbecho, is the most serious pest of lanzones nowadays. It has been known to be exclusively associated with this fruit crop since its first reported occurrence in 2009. In this paper, however, a new host record is reported for the first time, the high-valued cacao, Theobroma cacao L. Identification utilized the total evidence provided by both morphological details and molecular analyses (https://doi.org/10.62550/RI21061042)

This study involved 832 freshmen students enrolled in the course Introduction to Agriculture from 2009 to 2014 from the College of Agriculture and Food Science and the College of Human Ecology, University of the Philippines Los Baños, to determine the perception of youth towards the field of agriculture and its degree program. Using quantitative parameters and correlation analysis, the relationship between the demographic characteristics and the freshmen’s perception towards agriculture was determined. Students’ demographic characteristics (age and gender) are positively correlated with the student's perception of agriculture. Initially, the majority (58.3%) of the freshmen have a negativ...

The agroecological practice of intercropping, meaning farming of two or more crop simultaneously in the same field has recently reaped renewed interest for developing more sustainable cropping and food systems. This technology gained immense interest to marginal farmers of Bangladesh for better economic return from small parcel of their cultivable land. This study evaluated the variants of intercropping system of turmeric (Curcuma longa) + okra (Abelmoschus esculentus) having yield advantage and profitability. The study was conducted during the crop season of 2017 and 2018 at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh. Five intercropping combination, viz ...

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 of cotton cultivars. Crop growth rate, plant height, sympodial branches per plant,...

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 varying growing environments. NSIC Rc202H is the highest yielder among genotypes duri...

A clear understanding of genetic diversity in weedy rice is important in improving protocols for its conservation, ex situ. To this end, Asian collections of weedy rice together with accessions of the wild AA genome species Oryza nivara Sharma et Shastry and Oryza rufipogon Griffith, and the cultivated species, Oryza sativa L. were characterized using 16 qualitative morphological traits and 18 SSR markers. The Shannon-Weaver index (H’) revealed higher diversity in the weedy (mean H’ = 0.76) and wild O. nivara (mean H’ = 0.79) and O. rufipogon samples (mean H’ = 0.69) compared to the cultivated samples (mean H’ = 0.44). The weedy forms showed high preference (> 90%) for high grain shatt...
