Due to the minimal total land area and population, the Philippines will not contribute significantly to climate damage. However, the country is at the forefront of bearing the brunt of the ill effects of climate change due to its geographical location. Statistical analysis of the simulated yield and of the actual yield in LTFE was performed to determine the degree of probability of yield predicted by DSSAT.
Using the LSD test at the 5% significance level, the probability that the simulated yield will occur under actual conditions is only 41% with a deviation of 4% from the actual yield value. This low probability prohibits the study to proceed with the analysis, because the yield performance of the varieties in LTFE cannot be fully verified that it was influenced by the weather parameters Rf, TO and SR, which were the input data in DSSAT. Since the actual LTFE yield and DSSAT-simulated yield of IR72 are not consistent, simulations were no longer performed for IR8 and IR36.
Identification of growing degree day (GDD) requirements at different phenological stages of public hybrid rice parents and other inbred cultivars AOV Capistrano, JJE Aungon and JEG Hernandez. Now that the earth is facing the onset of climate change, information on GDD requirements and its optimization is especially useful as surface temperatures become warmer and crop durations become shorter. Shorter physiological maturity also means shorter phenological phases, which could have serious consequences in terms of farm management activities, since the performance of most agricultural activities is based on the phenological phases of the crop.
Synchronization of flowering time may be the best use of information related to accurate phenological stages, because unsynchronized flowering between hybrid rice parents would spell disaster for hybrid rice seed production, so the phonological stages of rice yield must be accurately identified. The IGC is equipped with a microcontroller (Arduino MEGA2560) which automatically controls the switching on and off of other electrical/electronic components of the IGC by maintaining a certain range of the desired air temperature in the IGC. It is also equipped with a DHT22 temperature sensor and a liquid crystal display that shows the air temperature inside and outside the IGC in real time.
Analyzed the daily rainfall data and prepared graphs of the agro-climatic indices based on 39 years (1978 to 2014) of data from the PAGASA-MMSU Agromet station, which provided the recommended planting schedules for rainwater in Ilocos Norte. There was a very low probability of excessive rainfall in May and June, ranging from 12 to 33%, and the rest of the months is zero (Figure 8). Accurate planting calendars have been developed based on the analysis of the various agro-climatic indexes, where sowing of rice should begin immediately after the beginning of the rainy season and harvesting should fall during the period when the DWHR should not be lower than 70% , as follows: (1) For early rice varieties (≤110 DAS), sowing is recommended in the third to fourth week of June, with an average weekly rainfall of 78 to 74 mm, and harvested in the fourth week of September to the first week of June. October with DWHR of 76 and 81% respectively; (2) It is recommended to sow the medium-ripe varieties (111-126 DAS) from the first to the second week of June, with an average weekly rainfall of 62 and 49 mm respectively, and harvest in the third to second week of June. fourth week of October; and (3) it is recommended to sow the late-maturing varieties (≥127 DAS) in the fourth to fifth week of May with an average weekly rainfall of 62 and 79 mm respectively, and these will also be harvested in the fourth week of September until the first week of October.
The entire construction is dome-shaped, and is considered to be nature's most efficient form, as it covers, among other things, the largest floor area with the smallest total area of wall and roof. Unlike in drip irrigation systems, where there is still the possibility of under-watering (due to water-stressed plants) or over-watering (too much water applied due to oversaturated root zone) due to miscalculations on the part of the farmer, with capillarity, a stable supply of water is precisely located at the bottom of the root zone and distributed throughout the vicinity of the capillary action, thus always available and ready for collection by plants. The experimental setup used to evaluate the water-bearing capacity of the selected wick materials.
Initial field setup of the capillation system using cotton yarn as wick and green chilli as test crop.
Enhancing the Adaptive Capacity of Rice Farmers through Diversification of Household Sources of Food and
Improving the adaptive capacity of rice farmers by diversifying household food sources and. Among the more important working parts were the chimney, the steam generator and the ignition chamber cover, which needed to be replaced at most every six months for a weekly operation of the carbonizer. This was due to the fact that these parts are the ones exposed to extreme heat.
When designing the commercial prototype, these parts will be made of stainless steel to extend their lifespan. A new heat recovery attachment for the CtRH carbonizer was also designed and manufactured in response to the request of the municipal government of Laoac, Pangasinan, to develop a dryer for use in the production of dried tilapia (what they call. To suit the application to maximize it, the attachment is designed not only for drying fish, but also for other products (root vegetable chips, charcoal briquettes, etc.) and for other functions such as frying fish and chicken, but also for baking, due to the changing containers and placing them in the correct location relative to the heat source.
Rice duck production enables farmers to obtain higher yields while reducing the application of fertilizers, herbicides and insecticides. Azolla is a floating fern and belongs to the family of Azollaceae, which is responsible for the fixation and assimilation of atmospheric nitrogen. This study aims (1) to determine the effect of ducks and azolla on soil quality, methane emission, productivity and economics of rice production (2) to determine the effect of the release of two groups of ducks on weeds, snail and arthropod diversity, and determine diseases. occurrence (3) to determine the effect of azolla on duck growth and development.
The apparently higher yield obtained with 0-40-40 kg NPK/ha treatment was due to lower stem borer attack (18% damage). Income earned from rice production under DS was also generally low, ranging from -Php5,780.50 to Php19,828.00 due to low yields. Income from duck production was also generally low due to high mortality (approximately 30%) due to poor quality stock and transport stress in the ducklings (Table 4).
An additional income of about Php 19,500 was obtained from duck production with and without azole treatment (Table 5). Cumulative methane emission (718.7 kg CH4/ha) of rice plants integrated with duckweed and azole application was significantly higher compared to those with only NPK (129.9 kg CH4/ha, NPK+ azole (109.6 kg CH4/ha) and PK alone (90.2 kg CH4/ha) IPDTK - Insect Pest Diagnostic Toolkit IPM - Integrated Pest Management IRRI - International Rice Research Institute IVC - In Vitro Culture.
