“…The whole experimental field area was prepared dry by plowing once, rotavating 2-3 times, and leveling once using a four-wheel tractor with an attached rotavator and leveler to achieve well-pulverized soil. After 2 wk, a drought-resistant inbred variety (NSIC Rc 222) was dryseeded using a hand-tractor-drawn multipurpose-seeder at a 60 kg ha -1 seeding rate (Bautista et al 2019). Compacted bunds and canals spaced at 0.5 m between plots as buffer zones were constructed to reduce seepage between plots during irrigation.…”

The use of herbicides in combination with hand weeding has been shown to be effective against a variety of weeds in irrigated and rainfed wet direct-seeded rice in the Philippines. In the case of dry direct-seeded-drip-irrigated rice; however, these aspects are not known. A study was conducted to determine the influence of two weed control techniques on weeds, yield, and economics of dry direct-seeded-drip-irrigated rice under Philippine conditions. Four treatments – [T1] unweeded; [T2] application of pre-emergence herbicide using pretilachlor, followed by two times hand weeding; [T3] application of post-emergence herbicide using bispyribac-sodium, followed by two times hand weeding; and [T4] weed-free using the sequential application of pre- and post- emergence herbicides followed by six times hand weeding – were tested and arranged in RCBD with three repetitions. T1 has the highest weed density and biomass with lower grain yield (901.8 kg ha–1) but no net income. T2 and T3 had lower weed biomass than T1 but could not be compared with T4, where no weed density and biomass were recorded at 15, 30, and 45 DAS (days after seeding) in both dry and wet seasons. Grain yields at T2 (3,794.4 kg ha–1) were not significantly different from T3 (4,341.3 kg ha–1) except when compared with T4 (5,7245 kg ha–1). Net income in T2 was higher by PHP 20,575.1 over T1 and T3 by PHP 9,831.4 over T2. T4 had the highest grain yield among all treatments and achieved an advantage of PHP 45,272.1, 24,697.0, and 14,865.7 over T1, T2, and T3, respectively, in terms of net income. Herbicide application followed by hand weeding reduced weed growth and improved rice yield and net income. The combination of pre- and post-emergence herbicides followed by six times hand weeding was much more effective at suppressing weeds and achieving higher grain yield and net income.

“…Analysis of differences in seed damage by the two seed metering devices using one-way ANOVA (Table 3) showed statically significant differences (p < 0.05) with the right hand seed metering device damaging more seed (5.2%) than that on the left hand side (3.7%). The relatively high seed damage may be attributed to flaws in the fabrication of the metering devices; for example, [26] attributed high percentage of damaged seeds to inadequate clearance in the seed metering device. According to [10], seed damage increased with increasing metering device speed and this was attributed to shearing and jumping of seeds against the wall of the hopper at high speeds and the magnitude of damage depended on the strength of the seeds.…”

About 62% of the maize produced in developing countries is cultivated manually owing to limited access to appropriate technology. Available technologies perform a single operation, necessitating farmers to buy multiple implements, which is expensive. In this study, an ox-drawn tool integrating a plough, planter and cultivator for small-scale maize farming was developed and its performance evaluated. Planting and cultivating units were designed and fabricated for assembly onto an existing standard ox-plough beam. The integrated tool was tested in the field to assess the effectiveness and efficiency of cultivation and planting of maize. Results showed that the planting unit had an average seed rate of 35.4 kg/ha with a seed damage of 4% and an effective field capacity of 0.15 ha/h at a field efficiency of 87.3%. The cultivating unit had an effective field capacity of 0.1 ha/h and a weeding efficiency of 86%. The efficiency, effectiveness and reliability for field operations are superior to manual operations currently used by farmers and are comparable to single-unit prototypes developed in other countries. This demonstrates the technical feasibility of integrating planting and cultivation units onto an existing mould board plough instead of buying multiple tools.

“…A multi-purpose seeder (MPS) was developed for DDSR, coupled with cultural packages such as improved crop establishment, appropriate variety, and nutrient management (Bautista et al 2019). It was concluded based on a 3 yr (2018 − 2020) on-farm trials (136 farms) in selected rice growing areas in the Philippines covering 16 provinces that the current seeding rate of 240 kg ha -1 can be reduced to 60 kg ha -1 without sacrificing the yield level (Bautista et al 2022). Moreover, DDSR resulted to a reduction in crop establishment (seed rate, labor cost, etc.)…”

“…Moreover, DDSR resulted to a reduction in crop establishment (seed rate, labor cost, etc.) by 20 − 47% (Bueno et al 2022), reduction in the cost of producing per kg of rice grain yield by 15 − 25% (Bautista et al 2022;Bueno et al 2022), an increase in grain yield by 15 − 25% (increment of 0.6 − 0.8 t ha -1 ) attributed to the uniform crop establishment by mechanized seeding and imposed best DDSR management practices (Bueno et al 2022), and an increase in the Return on Investment on a per hectare basis, ranging from PhP 8050 to as high as PhP 14150 (Banayo et al 2022).…”

This study was conducted to evaluate the variability of net income and return on investment (ROI) as affected by grain yield, cost of production, and gross income across provinces wherein the mechanized dry direct seeding technology was being deployed. The study was conducted during 2019 wet season involving 54 sites from 14 provinces with farmers practicing mechanized dry direct seeding technology under rainfed lowland condition. Grain yield varied (0.72 – 6.73 t ha-1) across provinces and within each province. Total cost of production varied (PhP 23032 – 43421 ha-1) across provinces. Most sites in Cagayan had high cost of production while low in Negros Occidental. Fertilizer cost was the major expense of more than 50% of rice farmers across provinces. Gross income ranged from PhP 32939 ha-1 (South Cotabato) to PhP 73873 ha-1 (Abra). Highest net income was obtained in Sultan Kudarat due to high yields. Net income was less variable in Ilocos Sur while highly variable in South Cotabato. The return on investment (ROI) of different provinces varied (71.61 ± 62.63%). Low ROI and less variability were noted in Ilocos Norte, Ilocos Sur, and La Union. Across provinces, 60.7% of total variation was explained by variations in grain yield. About 50% of variations in ROI was associated with cost due to land preparation and pesticide application. Fertilizer cost accounted for the high ROI in Abra and Antique. The cost of harvesting significantly affected ROI in Albay, Antique, Cagayan, Camarines Sur, Ilocos Norte, Ilocos Sur, and South Cotabato. In general, variability in ROI across provinces were affected by grain yield levels, or the total or the specific items in the cost of production, which is site or province specific. From the information generated, interventions can be formulated based on identified limiting factors specific to site or province.
