For the best growing condition, plow and harrow the field 2-3 times to remove the weeds and achieve the desirable soil structure. Plant one shelled peanut seed per hill at a distance of 5-10 cm during the dry season and 10-15 cm during the wet season. Weeding must be done regularly because peanuts are slow growers and cannot compete with weeds. Even though peanuts are relatively drought tolerant, it needs sufficient water during their pod-developing stage. It is recommended to water lightly but frequently. Peanuts are harvested 90-140 days after transplanting. Harvesting is done by passing a plow on the field before completely uprooting the plants. The visual signs of peanut maturity include gradual withering and yellowing of leaves, hardness of most pods, having 70-80% prominent pod veins, and the seed kernels being plump and full. Kankong, also called swamp cabbage, is a leafy vegetable known for being easy to plant and propagate. The young kangkong tops are commonly added to the dish sinigang. There are two classifications of kangkong depending on its preferred growing environment. The aquatic kangkong prefers to grow in swampy or flooded conditions. It grows about 10 meters in length, and its leaves are broad and dullpointed. In comparison, the upland kangkong grows in dry or moist soil. It is usually planted during the dry season of the year. Upland kangkong leaves are narrow and pointed. Kangkong, given that there is an abundant source of water, can be grown in any season and anywhere. It is propagated either by cuttings or seeds. Kangkong seeds or stems are planted at a distance of 30 cm between rows and 30 cm between hills. To boost the growth, 100 grams of complete fertilizer (14-1414) can be broadcasted seven days, sowing every 2 meters of the planting bed, followed by 50g of the same fertilizer on the 14th day after sowing. Regular weeding and irrigation are necessary for it to grow optimally. Kangkong tops or shoots can be harvested three to four weeks after transplanting.
