“THE EFFECT OF "HUGAS-BIGAS” ON THE GROWTH OF PECHAY (BRASSICA PEKINENSIS) PLANTS”
THE EFFECT OF "HUGAS-BIGAS” ON THE GROWTH OF PECHAY (BRASSICA PEKINENSIS) PLANTS
A study on the different nutrients present in "hugas-bigas" was conducted. Pechay (Brassica pekinensis) plants were divided into five groups. The first group was watered with 100 percent concentration of the first washing, the second group with 50 percent concentration of the first washing, the third group with 100 percent concentration of the second washing, the fourth group with 50 percent concentration of the second washing, and the fifth with tap water. The "hugas-bigas" was also tested for the presence of nitrogen and phosphorus, as well as soil and water pH. Observations of plant growth showed that the 50% concentration of the second washing contributed to the highest growth of pechay plants. The first washing of "hugas-bigas" had a 31.9 percent Nitrogen concentration while the second washing had an 18.2 percent concentration.
Rice is the staple food of the Filipinos. It is a rich source of carbohydrates. Before cooking rice, "stone" and "husks" are picked out. Dust and mud are then washed away by water. However, some nutrients are also lost — dissolved in "wash water" or what Filipinos call "hugas-bigas." Watering plants using "hugas-bigas" is a practice observed by Filipinos in rural areas. Plants watered by "hugas-bigas" are observed to have considerable improvement in growth. This study aims to use "hugas-bigas" in watering pechay (Brassica pekinensis) plants and to scientifically determine its effect on growth. The nutritive content of "hugas-bigas", specifically its nitrogen, phophorus, and potassium content will also be noted and determined. C. Significance of this project
To be able to understand all there is to know about Pechay’s
D. SCOPE AND LIMITATION
The scope of the study will include the determination of the Nitrogen, Phosphorus, and Potassium (N, P, and K) content of the "hugas-bigas." The pH of the "hugas-bigas" and the soil samples will also be determined. The height of the plants will also be measured. However, environmental factors such as sunlight, rainfall, humidity, temperature, air pressure, wind velocity, and illumi¬nation cannot be kept constant for all set-ups.
E. Definition Terms
Pechay- Chinese cabbage can refer to two distinct varieties of Chinese leaf vegetables often used in Chinese cuisine. These vegetables are both variant cultivars and subspecies of the turnip and belong to the same genus as such Western staples as cabbage, broccoli, and cauliflower.
REVIEW OF RELATED LITERATURE
Pechay (Brassica Pekinensis) is also called Chinese cabbage, petsai, won Bok and nappa. It is a versatile garden vegetable that may be used in making salads, coleslaw, or added to other stir-fried vegetables. Its crisp, tender leaves have a milder and sweeter taste than true cabbage. It is a good source of vitamin A, folic acid and potassium (Van Syk, 1996). The average pechay has a cylindrical head of four inches thick and a length of up to 18 inches long. The predominant variety of the petchay has creamy yellow crinkly thickly veined inner leaves. It outer leaves are light green with a white midrib. The pechay is available all year round and best planted in
The summer. The heads of the mature Chinese cab-.' bage are normally harvested when it is fully developed. It takes 70 to 90 days from planting for the pechay to reach maturity.
Rice (Oryza sativum) is a principal food of almost half the world's population. Rice flourishes in Southeast Asia where there is warmth and moisture. It reaches an average height of around 1 metre. The fruit, a grain, is produced on the nodding panicle of spikelets at the apex of the...
