This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T. aman cropping system. Four different tillage practices, namely, zero tillage (ZT), minimum tillage (MT), conventional tillage (CT), and deep tillage (DT...

The crops that we grow for food need specific climatic conditions to show better performance in view of economic yield. A changing climate could have both beneficial and harmful effects on crops. Keeping the above view in mind, this study is undertaken to investigate the impacts of climate change (viz. changes in maximum temperature, minimum temperature, rainfall, humidity and sunshine) on the ...

in recognition of the value and limitations of available water resources in agriculture and the occurrence of periodic drought in iran, water conservation and optimal usage of available water is essential. the main objective of this study was to optimize field water management and cropping patterns using deficit irrigation. the effect of reducing water consumption on different growth stages usi...

Lack of adequate seed-zone moisture is a major problem in the timely sowing of wheat (Triticum aestivum L.) after maize (Zea mays L.) in rainfed areas of north-west India. Field experiments were conducted during 1993±1997 in an acid Al®sol (typic Hapludalf) in north-west India to conserve rainwater in situ by using four combinations of mulch and tillage practices, and using the conserved moistu...

Conducting research on monitoring contaminated fields by heavy metals is necessary in order to achieve sustainable agriculture, increase product quality and keep public health. This study was carried out using split plot experiment based on randomized complete blocks design with three replications during 2014-2015 in Shavor Agricultural Research Center in order to evaluate the effect of croppin...

The pending approval of the unconfined release of Roundup Ready wheat in North America has brought to the attention of regulators and scientists in North America the issue of coexistence of genetically engineered (GM) and non-GM crops. In Canada, there has been great adoption by farmers of Roundup Ready and other GM canola varieties. At the time of commercial release of GM canola in Canada no s...

In this study, the comparative advantage of main agricultural products and its relation to cropping pattern was studied in Ilam Province. For data analyzing the comparative advantage and government policies effects indices, Policy Analysis Matrix (PAM) were used. The obtained results for the comparative advantage indices of Domestic Resource Cost (DRC), Social Cost Benefit (SCB) and Net Social ...

Rice-wheat production is an essential component of cropping systems in the Indus-Ganga Plains (IGP) which play a pivotal role food security south Asia. These crops are being cultivated on area about 13.5 M ha South In rice-wheat system, major reason for lower wheat grain yield use unwise tillage practices during seedbed preparation, cultivation late maturing rice varieties, water shortage, labo...

The research focused on the effects of previous cropping and fertilizers on the LAI, rhythm of the dry matter, leaf disease intensity and amount of yield. Long term field experiments’ results proved that the previous crop fundamentally determines size, rate and dynamics of the dry matter formation in the spring time vegetation period. The LAI index and crop results of winter wheat can be influe...
