Purpose: Proso millet (Panicum miliaceum L.) is an underutilised minor grown as a rain-fed crop in subsistence farming systems tropical African and Asian countries including Sri Lanka. It identified climate-resilient that exhibits huge potential to diversify conventional systems, however few modelling studies have assessed this crop, especially the tropics. The objective of study calibrate vali...

The self-sufficiency ratio and national average yield of wheat are low in Japan. Reducing the gap receiving government subsidy for grain quality vital strategies profitability. Elucidating optimum nitrogen application scheme is awaited to attain both higher appropriate protein content (GPC) cultivation Such decision support can be realized by integrating field experimental knowledge crop growth...

The increased frequency of climate extremes associated with ongoing change has the potential for significant impacts on maize grain yield in maize-producing regions worldwide. In this study, we used a modeling approach to investigate effects different types climatic Northeast China. We combined annual mean air temperature and accumulated precipitation data divided years into 9 categories, using...

 APSIM(Agricultural Production Systems Simulator) is a software system which allows (a) models of crop and pasture production, residue decomposition, soil water and nutrient flow, and erosion to be readily reconfigured to simulate various production systems and (b) soil and crop management to be dynamically simulated using conditional rules.  A key innovation is change from a core concept of ...

Introduction Soil type plays a major role in nutrient dynamics and soil water which impacts crop growth yield. The influence of characteristics on is usually evaluated through field experimentation (in the short term) crop-soil modelling long-term). However, there has been limited research looked at effect model structural uncertainty outputs different types. Methods To analyze impact inputs un...

Lowland rice yields in East Africa remain low despite favourable hydro-edaphic conditions as benefits from improved cultural management vary between and within wetland types interactions are poorly understood. Hence, multi-year agronomic field experiments were established to assess the differential responses of lowland (rainfed 0 60 kg N ha ?1 , irrigated 120 + PK ) position a floodplain Tanzan...

Abstract Yield is a function of environmental quality and the sensitivity with which genotypes react to that. Environmental characterized by meteorological data, soil agronomic management, whereas genotypic embodied combinations physiological traits that determine crop capture partitioning resources over time. This paper illustrates how genotype responses can be studied combination simulation s...

Floods and droughts are the events that most threaten crop production; however, impact of floods on crops is still not fully understood often under-reported. Nowadays, multiple sources information approaches support estimation agricultural losses due to floods. This study aims understand differences in loss estimates provided by two conceptually different (crop models expert-based models), eval...
