    Indonesia's population is increasing and conscious of the nutritional requirements lead to increase the demand for the vegetables including lettuce, it make lettuce decent to cultivate more in order to supply high consumer demand and larger market opportunity. Actions that need to be considered in the planting of lettuce is attention to the factors that affect the growth and production such as soil fertility and irrigation. In doing fertilization to note a few things that will be fertilized plants, the type of fertilizer used as organic fertilizer and inorganic fertilizer and provisions. In addition to nutrient availability factors affecting plant growth is unfulfilled needs water for crops. Water requirements can be met by the plant through the soil to the mechanism of water absorption by roots. From the results of this study concluded that the growth of lettuce plants affected by factors of chicken manure and water provision as well as variations in the interaction between the two factors, the growth of lettuce plants, the better to increase the use of fertilizers in the chicken coop but lettuce plants tend to decrease with soil moisture content 100 % field capacity and the interaction treatment of chicken manure 25 tonnes / ha with soil moisture content 75% field capacity seem to be more likely to affect this kind of plant growth on plant height and leaf area of lettuce plants, whereas combination treatment of chicken manure 25 tonnes / ha with a water content 50% soil field capacity showed a better effect on the parameters number of leaves and plant fresh weight

    Soybean plant development can be implemented through the utilization of palm oil plantations. Peat soils have many constraints such as low pH, and poor-nutrient. On peat soil nutrient deficiencies can be overcome by the provision of organic and inorganic fertilizers, such as TKKS compost. These organic materials affect plants indirectly through the changes in physical, chemical and biological soil. Study aims to determine the best fertilizer composition for growth and production of soybean palm oil plantations on peatland. The study was conducted in Rimbo Panjang, Tambang District, Kampar regency, in October 2011 to February 2012. Research used Completely Randomized Design (CRD), 5 treatments and 4 replications. Treatment A (without fertilizer), B (TKKS 0 tons/ha and Urea, TSP, KCl 100% recommended dose, 2 tons/ha ash bunch and 1 week of incubation), C (TKKS 5 tons/ha and urea, TSP, KCl 75% of the dose, 5 tons/ha ash bunch and 4 weeks of incubation), D (TKKS 10 tons/ha and Urea, TSP, KCl 50% of the dose, 4 ton/ha ash bunch and 3 weeks of incubation), E (TKKS 15 tons/ha and Urea, TSP, KCl 25% of the dose, 3 tons/ha ash bunch and 2 weeks of incubation). The results showed treatment E, (TKKS 15 tons/ha and Urea, TSP, KCl 25% of the dose, 3 tons/ha bunch of ash and 2 weeks of incubation, a composition of the best treatments for crop growth rate (0.37 g), the number of pithy pods per plant (71.15 units), production per plot (603.04 g) and production efficiency (1466.22%).
