Abstract

The farm practice was conducted at Brgy. Mamala I, Sariaya, Quezon from July 2011 to February 2012. The study was intended to 1) Document the different farm practices done by a farmer-cooperator from the area 2) Collect weed samples infesting vegetable farms, take pictures of these samples and make an herbarium; and 3) Survey farmer’s demographic information. Farm practices documentation was conducted to be able to make a full report regarding the practices and procedures done by farmers in Brgy. Mamala I, Sariaya, Quezon. Activities of Mr. and Mrs. Jumawan, farmer-cooperator, were recorded, from land preparation to harvesting. Samples that were collected through farm visits were photographed and compiled with brief but sufficient information. Identification of weed samples was made possible with the help of the mini booklet entitled Major Weeds of the Philippines (Moody et al., 1984) and through personal consultation from Dr. William SM. Gruezo. Samples were cleaned, sun dried and pressed using manual presser and old newspapers. Results on the interview of 100 farmers in the area showed that most of the farmers used the conventional way of farming. Age bracket who works in the farm is 16-75 years old, mostly married male individuals. All of the farmers were from that locality. The bigger fraction of farmers owns the house while the rest rents. Their primary source of income is farming. On the actual farm activity, most of them do the plowing thrice and twice for harrowing, depending on the crops that they want to grow. Mechanical tools that the farmers use in the field are native plows, harrows, spade and shovel. Most of them owned the equipments while some rents from other farmers. Vegetable crops planted for this season were radish (RaphanussativusLinn.), pechay (Brassica rapa L.), green sili (Capsicum annuum L.), carrots (Daucuscarota Linn.), sweet potato (Ipomoea batatasL.) and cabbage (Brassica oleraceaLinn.). Majority of them acquire their seeds from Parungao Agricultural Store and Sariaya Agricultural Center, both were located at the town proper. Some gets their seeds from Mamala I Cooperative. For farmers who planted sweet potato, planting materials were from the previous season. Their source of irrigation is from the river and rainfall. Some provide canals for efficient water distribution and for the wet season. Fertilizers that they usually rely on are urea (46-0-0), complete (14-14-14), ammonium sulfate (21-0-0) and solophos (0-20-0). There were 23 weed species identified during this season. Among these species, 15 were seen thriving in association with different vegetable crops. These include Amaranthusspinosus (L).,Ageratum conyzoides (L.), Crassocephalumcrepidioides (Benth.) S. Moore., Galinsogaparviflora Cav., Drymariacordata (L.) Willd.Ex R. & S., Commelinabenghalensis (L.), CommelinadiffusaBurm.f., Cyperusrotundus (L.), Euphorbia hirta(L.), Cynodondactylon (L.) Pers., Polygonumbarbatum (L.), Portulacaoleracea (L).,Borrerialaevis (Lam.) Griseb., Borreriaocymoides (Burm.f.) DC. and Stachytarpetajamaicensis (L.) Vahl.Most farmers control these weeds mechanically through hand weeding while some used synthetic herbicides like Sharpshooter Plus (isoprophyl amine salt of glyphosate), 2,4-D (2, 4-dichlorophenoxy acetic acid), Roundup (isopropyl amine salt of glyphosate), Gramoxone [paraquat dichloride (1,1’-dimethyl- 4,4’-bipyridinium)]. A hyper-stik was used to hold and retain the applied herbicides on the leaf surfaces during an event of rainfall and irrigation. Average total cost for weed control for 1-ha land was ₱1,200.00-₱1,700.00.
