Arandela, Timothy Nelson D.
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.
The purpose of this study was to know the physiological characteristics of Peta rice variety as influenced by the time of nitrogen fertilization. The importance of this study was to help the farmers know the proper time of applying nitrogen fertilizer to their rice crop.
A Randomized Complete Block Design was used in this study. There were nine treatments replicated five times.
The treatments consisted of the following time of nitrogen applications from seeding: A—three and six weeks, B—three and seven weeks, C—three and eight weeks, D—three and nine weeks, E—three and ten weeks, F—three and eleven weeks, G—three and twelve weeks, H—three and thirteen weeks, and I—control (no fertilization).
The rice plants were planted in pots and were observed from seeding to maturity. The significant findings were as follows:
1. That the first nitrogen application increased tillering.
2. That two weeks after first nitrogen application height of plants increased.
3. That the panicle emergence and maturity of plants were greatly affected by the second nitrogen application.
4. That number of panicles was highest when nitrogen was applied three and nine weeks from seeding.
5. That grain yield in plants fertilized three and nine weeks from seeding gave the highest yield among all treatments.

Sargado, Juan Patrick D.
D’KAKAK Farm is a sugarcane plantation owned and operated by Mr. Jose P. Sargado. It started in 1965 with a one-hectare farm. Mr. Jose P. Sargado, 57 years of age with 5 children, earned his degree of BS in Agriculture major in Agronomy at Central Philippine University. He then worked as a teacher in a public school in Anilao, Iloilo and was later promoted as Disbursing Officer of the same school until his retirement on 1998. The land was inherited by Mr. Sargado from his parents. Since the land has not been used or planted before he decided to plant it with sugarcane for additional income aside from his compensation. After a couple of years, the land cultivated increased gradually through rental or purchase. At present, the farm has a total land area of twenty hectares, of which ten hectares is being rented.
For the past seven years to the present, the farm is being managed by his eldest son, June Sargado. He also finished his studies at Central Philippine University with a degree of BS in Mechanical Engineering. Being the eldest son, he was urged to help in the farm while still at school. Because of that experience and advices from his father, he was able to manage the farm effectively.
The farm is located eight kilometers from the town proper and twenty kilometers from the nearest sugar mill (Exhibit 1). It has a total land area of twenty hectares situated in three locations. Every area is assigned with a leadman called “encargado”. Decisions on the work to be done by the laborers are made by the manager through the leadman.

Lao, Mark Levi
The study was conducted at Brgy. Ma. Cristina, Jaro, Iloilo City from February 12 to March 19, 2011. The experiment was done to evaluate the general performance of laying quails as influenced by intermittent feeding. The experimental treatments included once a day, twice a day, thrice a day, and ad libitum feeding. The results revealed that quails in the ad libitum treatment had significantly (0.05) the highest feed consumption (2.21kg), laid the most eggs (105), had the highest average laying percentage (97.21%), the most productive (laying 0.97 egg per day per hen) and had the highest net profit of Php. 162.98. On the other hand, birds fed only once a day had significantly the lowest feed consumption (0.680kg), laid the least eggs (0), had lowest average laying percentage (7.23%), were the least productive (did not produce any eggs in the 2nd to 5th week) and had a net loss of Php. 130.32.
