Abstract

The sudden outbreak of COVID-19 pandemic has resulted to disrupted food supply and value chain worldwide. Hence, there is a need to improve production management to meet the demand for food without neglecting its value to ensure profit. The farms and processing facilities should coordinate in the production of raw agricultural materials and in processing of food products to be sold to consumers. In the Philippines, goat raising is an important component of farm activities. Improving its value chain will likewise improve its economic value benefitting smallhold farmers. In Region 2, an initiative to enhance the goat food value chain was implemented through strengthening partnership with the network of stakeholders. The goat raisers were organized so that the capability building programs to improve goat production management and their entrepreneurial skills are honed. The organized farmers were registered as association or cooperative to make them qualified for government assistance programs. A private partner on food processing was also assisted under the technology business program and later invested in the establishment of food processing plant. For this particular initiative, 11 goat raising municipalities represented by 403 goat raisers were benefitted. With the organized system of production, an increase in the volume of raw materials by 57% was recorded, while 3.3 metric tons of different chevon products were sold to different consumers. Additional value-added products were also identified to further increase the value of the commodity. At present, this value-chain scheme was already presented to concerned government agencies for implementation in wider area of coverage.

Abstract

An agronomic evaluation of test entries of the Multi-environment Trail (MET) comprising new rice genotypes developed by the International Rice Research Institute was conducted during the 2022 Dry Season at the experimental area of the College of Agriculture, Isabela State University. The test entries were shared by the ASEAN Ricenet, a network of research institutions, universities and government research agencies in the ASEAN region where ISU - Echague is an active member. The Trial was laid out in a Randomized Complete Block Design (RCBD) with two replications. Agronomic data were statistically analyzed using the STAR software version 2.0.1 A total of 36 rice cultivars were evaluated for plant height, maturity, productive tillers and yield performance. Significant variations on plant height and yield performance were observed. On the other hand, there were no significant differences among test entries in the number of productive tillers and maturity. Based on yield performance, the best entries are 7, 2, 18, 23, 1, 15, and 8. These entries had a yield of at least 6 tons per hectare. Another season of performance test is now being conducted to validate these initial results.

Abstract

The study was conducted at the Central Experiment Station of the Department of Research and Development of the Isabela State University-Cabagan Campus in 2022. It aimed to determine the performance of Cross Bred Earthworm, African Night Crawler (Eudrilus eugeniae) and Native Earthworm (Perionyx excavatus) in vermicomposting. Treatments tested were the following; T1 - 100% Cross Bred Earthworm T2 - 100% African Night Crawler (ANC); T3 - 50% Cross Bred Earthworm (CBE) + 50 % African Night Crawler (ANC); T4 - 50% CBE + 50% NE; T5 - 70% ANC + 30% NE). Results of the study revealed that T2has the highest volume of converted vermicast with a mean weight of 17.9 kg, followed by T5 with 17.8 kg , T1 (17.5 kg), T3 (16.6 kg), and T4 has the lowest converted vermicast with a mean weight of 16.5 kg. Statistical analysis of the data revealed that there is a significant difference among the different treatments mean at 0.5 level of significance (F=3.64, F-prob=0.0366, P=0.0000). The result of the nutrient analysis revealed that T1 has the highest nitrogen content with 0.61%, followed by T4 with 0.60%, T5 (0.59%), T3 (0.51%), and T2 has the lowest content with 0.48%. In terms of Phosphorus, T2 has the highest content with 0.18%, followed by T4 with 0.17%, T3 (0.15%), T1 (0.13%), and T4 has the lowest content with 0.11%. In terms of Potassium, T5 has the highest percentage of potassium content with 0.43%, followed by T4 (0.42%), T1 (0.40%), T3 (0.37), and T2 has the lowest content with 0.36%. Among the five treatments, T1 has the highest ROI with 5.69%.

Abstract

This research focused on the determination of the substrate combination that will yield a higher amount
of compost and faster decomposition with the use of Trichoderma. The productivity of vegetable crops, namely, okra (Abelmoschus esculentus), pechay (Brassica rapa), and eggplant (Solanum melongena) using the produced tricho-compost was also assessed. In addition, tricho-compost was compared to other commercially available organic fertilizers in terms of the growth and yield performance of eggplant. For the production of tricho-compost, results showed that T1 (10% P, 75% N, 15% C) gave the highest nutrient content of 2.52% N, 0.19% P2O5 and 0.16% K2O. The addition of Trichoderma significantly increased the rate of decomposition of the agricultural wastes. The higher the quantity of N-containing substrates used, the higher the nitrogen content of the compost produced. The effect of varying combinations of tricho-compost and inorganic fertilizers on the growth and yield performance of okra, pechay, and eggplant was also determined. Results showed that T5 (20 tons/ha tricho-compost + ½ inorganic fertilizer) obtained the highest plant height and fastest to produce flowers for okra. On the other hand, T4 (10 tons/ha trich-compost + ½ inorganic fertilizer) obtained the highest plant height and highest yield for pechay. Furthermore, T6 (full inorganic fertilizer) produced the tallest plants and highest marketable yield for eggplant. A comparative assessment of the effect of varying amounts of tricho-compost and commercial organic fertilizers on the growth and yield of eggplant was also conducted. Results revealed that the application of 40 tons/ha tricho-compost gave the highest plant height, fastest rate to produce flowers and highest yield. Moreover, increasing the amount of tricho-compost resulted in increased yield. The results suggest that the use of tricho-compost as an organic amendment is comparable to those commercially available organic fertilizers in the market.

Abstract

This research aimed to determine the properties and nutrient status of major soil series grown to corn in Isabela, Philippines to analyze the ability of the major soil series grown to corn to give a more lucrative and environmentally friendly farming choice for corn growers. The soil series analyzed were San Manuel Lower River Terrace, San Manuel Upper River Terrace, and Cauayan series. San Manuel Lower River Terrace has a moderately acidic pH (5.89) with medium organic matter (1.56%), low nitrogen (0.08%) low phosphorus (3.95 ppm), and low potassium (116.25 ppm). San Manuel upper river terrace has a strongly acidic pH (5.43), medium organic matter (1.69%), low nitrogen (0.09%), low phosphorus (4.64 ppm), and medium potassium (169.36 ppm), both of which were highly suitable to corn production. The Cauayan series has a strongly acidic pH (4.75) with low organic matter (1.30%), low nitrogen (0.07%), low phosphorus (2.48 ppm), and low potassium (52.66 ppm), and a clayey soil texture which constrains its ability to grow most crops. The results of this research recommend improving the technical know-how of farmer-respondents on appropriate fertilizer and pesticide use to improve soil conditions.

Abstract

In the Philippines, strawberries are known to be grown only in the highlands with favorable climates like Benguet and Baguio City where modern agriculture practices are common to achieve high yield. However, more consumers are becoming more health conscious due to the negative impact of chemicals and thus demand organic produce. This study titled “Development of organic production technology in low elevation areas in Cabagan, Isabela” was conducted to evaluate the different organic ameliorants, weed management, and naturally fermented solutions application, as well as determine the profitability of growing sustainable organic strawberries. Among the two varieties tested, the study revealed that the application of vermicompost with humus (T6) gave the highest yield (18,817 kg/ha) using the Sweet Charlie variety. Moreover, it is suggested to use plastic mulch (T2) as it lessens the weed incidence (120kg/ha) and attains more yield (13,093 kg/ha). Further, the Japanese shoga variety performs well with the application of combined KAA and vermitea (T2). In terms of fruit quality, Japanese Shoga was found sweeter using the vermicompost with humus (10.47%), when applied with vermitea (10.06%) and mulch with Hagonoy (8.66%). With respect to the ROI, it was found that growing strawberry is profitable using low-cost inputs. Considering the results, growing strawberries can be considered a new investment and a new avenue for an agri-preneur business venture as it was proven adaptive yet a challenging plant species to grow under Isabela's condition.

Abstract

The study aimed to test and evaluate the efficacy of Himbabao Crude Leaves Extract (HCLE) against gastro-intestinal parasites of native chicken as compared to the commercial dewormer. Specifically, it aimed to identify the species of parasites and parasitic loads of native chicken, determine the effects of different doses of HCLE on parasitic larvae and parasitic ova in native chickens, determine the hematological values of native chicken, and determine how economical is HCLE as anthelmintic. The treatments used were as follows: Treatment 1 Positive Control - Commercial Dewormer; Treatment 2 Negative Control; Treatment 3 (2.5 mL of HCLE); Treatment 4 (5 mL of HCLE); Treatment 5 (7.5 mL of HCLE); Treatment 6 (10 mL of HCLE). The data collected include species of gastro-intestinal parasites, parasitic loads, efficacy of HCLE, hatchability of parasitic eggs, and dewormer production cost. Data were analyzed using the Analysis of Variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) was used to find out whether there is a significant difference among the treatment means. The most detected specie of parasite is Capillaria spp. followed by Ascaridia galli, Raillientina spp, Heterakis gallinarum, and lastly, Strongyloides spp. All the experimental animals were heavily parasitized and required treatment. HCLE and commercial dewormers have the same effect in terms of egg output. Oral administration of HCLE and commercial dewormers have no ovicidal and larvicidal effects. Spraying HCLE and commercial dewormer in animal feces has no ovicidal and larvicidal effects.

Abstract

The study sought to identify the species of parasites and parasitic loads of sheep; determine the ideal concentration of Himbabao Crude Leaves Extract (HCLE), and the effects of different concentrations of Himbabao Crude Leaves Extract (HCLE) on parasitic larva and ova in sheep. A total of 24 matured sheep that are heavily parasitized were used in the study. Treatments used include: T1 - 25% Himbabao Crude Leaves Extract (HCLE) and 75% Distilled Water; T2 - 50% HCLE and 50% Distilled Water; T3 - 75% HCLE and 25% Distilled Water; T4 - 100% HCLE; T5 - 100% Distilled Water; and T6 - Commercial anthelminthic. The experimental animals were set up in a Complete Randomized Design (CRD) with six (6) treatments and four (4) replications. Matured himbabao leaves were used in the study. Himbabao leaves were washed properly and ground using a blender. Distilled water was added during grinding. The ratio of leaves to water is 1:1 or equivalent to 100 ml is to 100 grams of leaves. The Himbabao crude leaves extract was given orally, once a day in the morning. The commercial anthelminthic were given as per recommendation. The study used in-vivo and in-vitro tests to determine the effectiveness of the test extracts on parasitic ova and larvae. The following data were collected: species of parasites, parasitic loads, parasitic egg output efficacy (PEOE), hatchability of parasitic eggs in-vivo and in-vitro, efficacy rate of HCLE on the parasitic larva, and hematological values of sheep. Data were statistically analyzed using IBM SPSS Statistics for Windows by IBM, New York. Analysis of variance (ANOVA) was used to determine the level of significance (p < 0.05) of the effect of the different concentrations of Himbabao Crude Leaves Extract on parasitic larva and ova. Strongyloides and Haemonchus were identified in the experimental animals. All the experimental animals are heavily parasitized and need treatment. Himbabao leaves extract (HCLE) has no effect on parasitic egg output. Himbabao leaves extract (HCLE) negatively affect the hatchability of parasitic eggs in both in-vivo and in-vivo tests and greater concentrations of HCLE kill parasitic larva.
