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.

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.

The study was conducted at the Central Philippine University College of Medical Science Laboratory, Jaro, Iloilo City from January 16 to February 1, 2018. The study aimed to evaluate the efficacy of different weed extracts as alternative to synthetic fungicide against sweet pepper anthracnose (Glomerella cingulata Stonem.). The study used fresh aqueous and dried ethanolic extracts that were performed separately and each was composed of six experimental treatments. The experimental treatments were laid out in a completely randomized design (CRD) with three replications. The results showed highly significant differences in the zone of inhibition between the plant extracts and the fungicide. In fresh aqueous extracts, all plant extracts showed no zone of inhibition while synthetic fungicide has the highest record of 34.22mm inhibition. Dried ethanolic extract shows that out of 4 plant extracts tested, only Boerhaavia diffusa showed antifungal activity with 14.66 mm zone of inhibition. The remaining plant extracts and water, which served as negative control, produced no zones of inhibition. On the other hand, synthetic fungicide, which was used as a standard chemical check, demonstrated by far the highest inhibition zone of 30.22 mm diameter.

Claveria, Roel Christian B.
The study was conducted at LEB 105, CARES Building, Central Philippine University, Jaro, Iloilo City from July 23, 2017 to September 16, 2017. The experimental treatments were consisted of four different growing media such as pure cocopeat, wood shavings, mixture of garden soil and sand, and no medium that served as the control. These were laid out in a completely randomized design (CRD) with four replications. The study was conducted to assess the different growing media on the growth and reproduction of Turkestan cockroach. Specifically, this study aimed to determine the body length gain, growth percentage, survival percentage and hatching percentage of the Turkestan cockroaches cultured in different growing media. Results of the study revealed that the four growing media had no significant influence on the body length gain and survival percentage. In growth percentage, the data showed that Turkestan cockroach grown in wood shavings had significantly the highest growth. In addition, cockroaches in the control treatment, sand and soil and cocopeat media had significantly gave the highest hatching percentage. From these results, it can be concluded that B. lateralis can be mass propagated even without medium.
