Modelling crop evapotranspiration (ET) response to different planting scenarios in an irrigation district plays a significant role in optimizing crop planting patterns, resolving agricultural water scarcity and facilitating the sustainable use of water resources. In this study, the SWAT model was improved by transforming the evapotranspiration module. Then, the improved model was applied in Qin...

This study was undertaken from the rainy season 2015 to winter 2016–17 at Uttar Banga Krishi Viswavidyalaya, Pundibari, West Bengal. The aim of arrive optimal tillage requirement in rice (Oryza sativa L.)–wheat (Triticum aestivum L.) system economize on energy, labour and time, work out production economics rice–wheat as a whole under various crop-establishment techniques. Unpuddled (UPTR) foll...

This research was conducted in 2007 and 2008 cropping seasons in the experimental field of Shahid Salemi, Ahvaz, south west of Iran. In each year, the study consisted of a split split-plot experiment, using Randomized Complete Block Design (RCBD) with three replications. Four irrigation levels including irrigationoff at the 8 leaf, the 12 leaf and the tasseling stages and optimum irrigation wer...

Fusarium moniliforme is one of the major seed borne pathogen rice in Bangladesh that causes significant yield loss. To observe incidence and transmission this pathogen, farmers saved seeds from BADC were collected pathogens detected by blotter method. The prevalence F. varied according to locations seasons. highest 18% infection was recorded Boro Netrakona district lowest 2% Gazipur district. E...

Plants have an important impact on soil microbial communities and their functions. However, how plants determine the microbial composition and network interactions is still poorly understood. During a four-year field experiment, we investigated the functional gene composition of three types of soils (Phaeozem, Cambisols and Acrisol) under maize planting and bare fallow regimes located in cold t...

The rice water weevil, Lissorhoptrus oryzophilus, is the most destructive insect pest of rice in the United States. Early planting of rice to avoid damaging infestations of the rice water weevil has long been suggested as a management tactic. A five-year study was conducted to characterize the influence of rice planting date on rice water weevil management in light of recent trends toward earli...

Abstract To contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings hybrid true seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old experimental genotypes transplanted into farmers’ production fields at contrasting locations: flat-bed on sandy soil and traditional ridge...

Due to rapid population growth and urbanization, paddy rice agriculture is experiencing substantial changes in the spatiotemporal pattern of planting areas in the two most populous countries-China and India-where food security is always the primary concern. However, there is no spatially explicit and continuous rice-planting information in either country. This knowledge gap clearly hinders our ...
