ABSTRACTDry direct-seeded rice (DDSR) cultivation is expected to reduce production costs compared with transplanted rice (TPR); however, its low N use efficiency (NUE) has hindered cost reduction. We conducted DDSR field experiments for 3 years using

Future agricultural management programs should consider the responsiveness of crops to increasing atmospheric CO2 concentrations ([CO2]) and temperatures. Eddo is an important tuber crop widely grown in Asia, but its response to [CO2] and temperature

The root system of maize tends to be shallower with plowing tillage than with rotary tilling in upland fields converted from paddy fields. Soil hardness and fertilizer distribution differ between plowing tillage and rotary tilling; thus, we investiga

We investigated the effects of tillage on growth, grain yield and root lodging of maize hybrids in upland fields converted from paddy fields in Andosol of northern Tohoku. Six hybrids were grown with rotary tilling or plowing (chisel plowing plus pow

Plowing is a more efficient tillage method than conventional rotary tilling in paddy fields. We thus investigated growth, grain yield, and quality of maize (Zea mays L.) using two tillage systems in crop rotation of paddy fields at Morioka (Andosol)

We conducted hydroponic culture experiments to characterize root traits in a rice cultivar ‘Puluik Arang’ that has been identified in a previous study as a cultivar that is adaptable to unflooded conditions. Root morphological traits and the expr

This study aimed to characterize the physiological and morphological traits that are associated with adaptation to unflooded soil conditions in rice. Four indica rice cultivars (Puluik Arang, Badari Dhan, Shwe Nang Gyi, and Ratul), which were previou

In order to enhance rice productivity under water-deficient conditions, it is essential to improve nitrogen (N) uptake ability or its use efficiency. The objectives of the present study were to examine the genotypic variation in N uptake ability and

Genetic improvement in water uptake ability and/or water use efficiency (WUE) of rice cultivars is one option to enhance productivity under water-limited conditions. We examined the genotypic variation in biomass production among 70 rice cultivars (6
