This study was conducted from September 19, 1985 to January 11, 1986 at the experimental field of the Crops Research Laboratory, College of Agriculture, Central Philippine University, Jaro, Iloilo City, to determine the best time of applying chicken manure and to determine the effect of chicken manure on the growth and yield of transplanted IR64 rice.
A total land area of 130.35 square meters was divided into three blocks, each block representing a replication. Each replication was further divided into four plots, each one having a. dimension of 2 x 4 meters. Each plot was fertilized with inorganic fertiliser in combination with chicken manure. The chicken manure were applied 4, 3, 2 and. one week before transplanting to supply 30 kg of nitrogen per hectare. The plots were fertilized with inorganic fertilizer materials using ammonium sulfate end muriate of potash one day before transplanting. Last application of inorganic fertilizer using ammonium sulfate was done 42 days after transplanting. All plots received an equivalent of 60-0-45 kg N, P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O per hectare, respectively, coming from "both organic and, inorganic sources. The experimental treatments were arranged in a, randomized complete block design replicated three times.
The results showed that the different timing of chicken manure application did not significantly affect plant height in all growth stages of the rice plant. Similarly, tiller count in all stages of growth except at 2 weeks after transplanting were not also affected.
Furthermore, the different timing of chicken manure application did not significantly affect the number of days from transplanting to flowering, weight of grains per panicle end weight of unfilled grains per hill. On the contrary, however, the weight of filled grains per hill was significantly affected by the different timing of chicken manure application at the 5 percent level of probability. Accordingly, the heaviest weight of filled grains was obtained from plants applied with chicken manure 4 weeks before transplanting, which was comparable to that obtained from plants applied with chicken manure 2 weeks before transplanting. These were significantly higher to the weight of filled grains obtained from plants applied with chicken manure 3 weeks before transplanting. The lowest was obtained from rice plants supplied with organic fertilizer one week before transplanting.
Yield of 90.03 cavans per hectare was observed from plots fertilized with chicken manure 2 weeks before transplanting. This yield was significantly more over the yield of plots fertilized 4, 3 and a week before transplanting which were 78.45, 75.76 and 71.94 cav/ha, respectively.
The return on investment analysis of the results revealed that for every peso invested a corresponding 4.63, 3.75, 3.28 and 3.50 return was obtained by applying chicken manure 2, 3, 4 and a week before transplanting, respectively.
Based on the results, the researcher recommends the application of chicken manure at two weeks before transplanting for maximum returns.

Palada, Manuel C.
Recently, three medicinal plants (herbs) attracted the attention of the population globally because of the medicinal value and health benefits these plants provide when use following recommended and suggested information. These plants are Ashitaba (<em>Angelica keiskei</em>), Insulin plant (<em>Costus igneus</em>), and Serpentina (<em>Rauvolfia serpentina</em>).

Cabarles, Jaime C. Jr.
The farming of today is faced with numbers of issues. These are about availability and cost of land, finding the farm hand, higher cost of production inputs, changes in climatic conditions, fluctuating prices of agricultural commodities, the category of packages of technology to be adopted, and age of agripreneur. The term agripreneur refer to the person who invested in agriculture with the goal of producing animals, crops, or both intended for market. These are the farmers who are investing their money and aiming for a profit in return. They are not a typical farmer who considers their undertaking more on the “way of life rather than integrating business on it.”
The Philippine market is confronted with the availability and price of rice. A suggested retail price is implemented to control the prevailing rate in the market. Aside from the so-called hoarding of rice grain, the other issues can be pointed out into the economic development. The rapid development in the city is expanding towards nearby municipalities. This development can be classified into commercial, residential, and industrial. However, the first-two classes dominated that converted more extensive areas of prime land into subdivisions and later on emerges the malls in the proximity. With such development, these lands producing hundreds of sack of rice were all gone with the snap of fingers. It led to the movement of farming from highly productive to idle and somewhat low productivity lands which significantly affect the supply of rice in the market.

Palada, Manuel C.; Vergara, Benito S.
The survival of rice seedlings (<em>Oryza sativa L.</em>) after complete Submergence in water decreased with increased duration of submergence; with increased depth, temperature, and turbidity of water; and with increased rates of N fertilization. Survival increased with high light intensity and plant carbohydrate content. Factors that influence the survival of submerged plants also determine the amounts of N and carbohydrate in the plant.
