Abstract:
... Besides being an essential macronutrient for plant growth, potassium (K) also acts as a stress-relieving agent against various biotic and abiotic stresses, especially water stress. An experiment consisting of three lowland Thai rice varieties (Pathumthani 1, RD57, RD41), two cultivation methods [dry direct seeding (DDS), transplanting (TP)] and four K doses (0, 80, 120,160 kg ha⁻¹) under alternate ...

Abstract:
... Parthenium weed (Parthenium hysterophorus L.) is an emerging weed species in direct-seeded aerobic systems of rice production. This two-year field study was conducted to evaluate the effect of five different densities (0, 5, 10, 15 and 20 plants m⁻²) of parthenium weed on rice yield and yield-related attributes. Parthenium weed produced ca. 38 to 178% higher biomass at its densities of 10 to 20 pl ...

Abstract:
... In rainfed lowland rice-based systems, increasing labour scarcity due to off-farm employment is encouraging farmers to switch from transplanting to dry direct seeding (DDS). To assure stable productivity at a level comparable with or superior to transplanting, DDS management must ensure rice seedlings have access to nutrients in order to be competitive with weeds, which must also be suppressed.

However, the potential effect of this change on agricultural ecosystem CH4 flux (FCH4) are less stud ...

Abstract:
... The rice-wheat rotation is the dominant cropping pattern in the Terai ‘food basket’ of Nepal. Current production practices require significant labor, water, and energy which erode profitability and, hence, incentives for intensification. Dry direct seeded rice (DSR) and zero tillage wheat (ZTW) have been widely tested on experiment stations as alternative establishment technologies in South Asia. ...

Abstract:
... Rice productivity in Eastern Indo-Gangetic plains (EIGP) is extremely low, in part due to the prevailing practice of cultivating long-duration transplanted rice under rainfed conditions which leads to water stress and significant yield losses in many seasons.
