Abstract:
This article 'Stem Borers (Sb) in Dryland and Wetland Rice' appeared in the International Rice Research Newsletter series, created by the International Rice Research Institute (IRRI). The primary objective of this publication was to expedite communication among scientists concerned with the development of improved technology for rice and for rice based cropping systems. This publication will report what scientists are doing to increase the production of rice in as much as this crop feeds the most densely populated and land scarce nations in the world.

Abstract:
The furrow-ridge system was designed to allow the cultivation of dryland crop species in lowlands, enabling rotation with rice. After harvesting the dryland species, farmers usually return with rice in the following cropping season, with costs associated with dismantling ridges before sowing rice. The possibility of sowing rice directly on residual ridges should be investigated to avoid these costs. The objective was to verify the ecophysiological adaptability of rice sown on residual ridges from the previous dryland crop in lowlands, and to identify possible factors impacting the physiologica

Abstract:
The information on rice genetic material is needed to create new high-yielding varieties adaptive to dryland. Local rice genetic resources have been tested to be tolerant under conditions affected by global climate change (increased temperature, pest/disease attacks, droughts). This study aims to identify and characterize the agronomic character of local rice in Musi Rawas (MURA) and North MURA Regencies, South Sumatra. The results of identification and characterization, as well as correlation and regression analysis, revealed that three local varieties have agronomic characteristics that dete

Abstract:
Productivity of local upland rice varieties are usually low, making farmers refrain to cultivate upland rice. This resulted in the low contribution of upland rice in production. However, farmers are still planting upland varieties of rice because of their desirability and adaptation to the environment. Therefore, we always need to develop new varieties that have high production and flavors that suit the tastes of society. The key to increase production of variety is providing sufficient nutrients during the growing period. This study aims to accelerate the availability of nutrients of organic

To respond to China’s policies of “balancing and supplementing high-quality farmland, converting dryland to paddy fields” and of improving the quality of drylands, large-scale dryland conversion to paddy fields has been recently implemented to improve farmland quality and increase grain production capacity in China. However, the effects of the conversions on the soil carbon (C) pool remain unclear. Therefore, in a karst area of Guizhou Province, China, we selected farmland soils that had undergone dryland-to-paddy conversion and planted with rice for one year, ensuring that the historical mana

Over all four systems, root colonization was greater in vertisol (22.3 % of roots) than in regosol (9.5 %) soil, possibly due to lower Bray-1 P content of the vertisol (6.2 v. 13.7 mg kg−1). Colon

Certain crops species have demonstrated an ability to mobilize sparingly soluble P sources. Objectives of this project were to 1) evaluate the effect of green manure (GM) crops and organic P fertilizers on the P nutrition of subsequent crops, and 2) investigate P fertility differences between organic and n

AbstractTriple S (Storage in Sand and Sprouting) is a root-based system for conserving and multiplying sweetpotato planting material at the household level. In sub-Saharan Africa, farmers predominantly source planting material by cutting vines from volunteer plants that sprout from roots left in the field from a previous crop. However, it takes 6 to 8 weeks after the rains start to produce enough vines for planting material, and normally these vines are infected by sweetpotato diseases and pests carried over from previous crops.

We ask, “What is different about deserts, relative to other habitats, in their patterns of diversity, temporal variability in productivity, and spatial heterogeneity?” We assess how such differences might modify extant theory, and sketch relevant examples.
