Socioeconomic survey with gender perspective for AWD in Colombia
https://hdl.handle.net/10568/90413
Abstract
Alternate Wetting and Drying (AWD) is a water saving technique thus helping farmers adapt to less water availability, it reduces the methane gas emission in rice production, and it increases/maintains productivity levels. The International Center for Tropical Agriculture (CIAT) and partners, are doing several studies to evaluate the feasibility of implementing this technology in Colombia. This necessitates an understanding of…

Pests and diseases of Brachiaria species
https://hdl.handle.net/10568/82027
Abstract
The main insect pests and diseases associated with Brachiaria pastures are considered, with emphasis on spittlebugs, the most damaging pests in tropical America. Outbreaks of the polyphagous burrowing bugs of the genus Scaptocoris, both in Brazil and Colombia, are of concern. Other pests discussed include leafcutting ants; the mound-building termites, Cornitermes cumulans and Syntermes sp.; the lepidopterans, Spodoptera frugiperda and Mocis latipes;…

Reproductive physiology, seed production, and seed quality of Brachiaria
https://hdl.handle.net/10568/82030
Abstract
Seed of six commercial Brachiaria species is extensively produced for pasture sowing. Production is restricted geographically and seasonally by photoperiodic flowering reactions. It also requires a prior control of vegetative tiller production, and therefore a reliable dry season. The necessary conditions are most readily found at high tropical latitudes. Seed crop management is mostly conventional. Vigorous…

Regional experience with Brachiaria: Asia, the South Pacific, and Australia
https://hdl.handle.net/10568/82039
Abstract
Brachiaria species occupy about 300,000 hectares in Asia, the South Pacific, and Australia. In Asia and the South Pacific, they are the most widely grown pasture grasses in the humid and subhumid tropics; in Australia, the area to which they are adapted is relatively small, but within it, Brachiaria occupies more than half the area of improved pastures. Brachiaria mutica, the first species introduced into the region…

Beyond taro leaf blight: A participatory approach for plant breeding and selection for taro improvement in Samoa

Abstract
The 1993 outbreak of leaf blight in Samoa resulted in the devastation of the staple taro crop and farmer's incomes from local and overseas markets. The preferred cultivars were all susceptible to the disease, and attempts to solve the problem through fungicides and changed cultural practices have had little impact Efforts to evaluate exotic cultivars and breed taro with…

The impact of participatory plant breeding (PPB) on landrace diversity: A case study for high-altitude rice in Nepal
https://hdl.handle.net/10568/81905
Abstract
Participatory plant-breeding (PPB) methods were used to develop two acceptable, cold-tolerant rice varieties in Nepal: Maehhapuchhre-3 (M-3) and Machhapuchhre-9 (M-9). Both were derived from the cross Fuji 102 Chhomrong Dhan. Following the introduction of these varieties from 1993 to 1998,the changes in the rice landraces and varieties that fanners grew were studied in 10…

Abstract
During 1984, intensive on-farm trials were conducted in northern, southern, and central Narino, Colombia, and emphasis was given to the continuation of var. trials and their expansion to determine economic levels and to verification trials. In northern and central Narino, a limited no. of verification trials were planted using the most promising components from 1982B. In both sets of trials, the new agronomic practices offered no yield advantage over farmers' practices…

Abstract
In Leyte, the long-term fertility trial under coconut showed significant responses to fertilizers after the second cropping cycle. Highest yields were obtained in treatments with 90 kg/ha of P O and 60 kg/ha of N and K O, while lowest yields were obtained in treatments without P application. In another trial there was a significant interaction between time-of planting and age-at-harvest. When intercropping maize within cassava…

Recent progress in cassava varietal improvement in the Philippines
https://hdl.handle.net/10568/82404
Abstract
The report covers varietal improvement for the period 1990-1993. Not much progress was made in the 1990/91 season due to the occurence of a super typhoon that damaged standing field trials. In recent years, however, progress in selection was made in terms of high yield and dry matter content and good plant type.
The cassava germplasm bank of PRCRTC has currently a total of 270 accessions, includeing 30 varieties introduced…
