Despite the potential to increase soil organic matter, cycle nutrients, and suppress weeds, there is a concern that cover crops (CCs) water use negatively impacts subsequent in water-limited environments. Cover crop management practices such as planting termination timing may mitigate detrimental of CCs semi-arid cropping systems. To determine effects under environments, we evaluated total CC b...

As a rainfed spring-sown crop, sunflower ( Helianthus annuus L.) is increasingly exposed to negative impacts of climate change, especially high temperatures and drought stress. Incremental, systemic transformative adaptations have been suggested for reducing the crop vulnerability these stressful conditions. In addition, innovative cropping systems based on low-input management, organic farming...

Rainfed agriculture is practised on 80% of the world’s agricultural area and generates 60–70% of the world’s staple food1 (FAOSTAT, 2005). In semi-arid and dry subhumid zones, rainfed agriculture dominates food production systems, and water is a key limiting factor to crop growth (SEI, 2005). Since approximately 70% of the world’s poor are women, the importance of rainfed sources of food weighs...

line to/cal/3/7c//bb/cno/5/cal//cno/sn64/4/cno//bad/dar/3/kl/6/sabalan was received from icarda under international winter wheat improvement in 1999-2000 cropping season. based on its favorable agronomic characteristics, it was selected for further evaluations in advanced and elite yield trials in main research stations of dryland agricultural research institute (dari) and on farm yield trials ...

information required to benchmark yields. These include Growers, breeders and policy makers require benchmarks to measure performance in regard to management of the crop, genetic improvement and prospects for investment and employment. Cropping systems are difficult to benchmark because of the unpredictable nature of the climate. In this paper previous attempts to benchmark sugarcane production...

An understanding of the relative impacts of the changes in climate variables on crop yield can help develop effective adaptation strategies to cope with climate change. This study was conducted to investigate the effects of the interannual variability and trends in temperature, solar radiation and precipitation during 1961–2003 on wheat and maize yields in a double cropping system at Beijing an...

The Thar Desert occupies about two-third part in the State of Rajasthan. Traditionally, agriculture in this region depends on the scanty rainfall. Irrigation was introduced in ths area by commissioning Indira Gandh Nahar Pariyojona (IGNP). The total irrigation potential is estimated as 13.87 lakh hectares. Canal irrigation has brought a significant change in the cropping pattern. The traditiona...

Background: Mixed cropping of forage grasses and legumes can potentially improve the performance herbivores. However, feasibility mixed-cropped with should be examined at different plant densities. Aim: This study aimed to evaluate growth characters chemical composition in dwarf napiergrass ( Pennisetum purpureum cv. Mott) Indigofera zollingeriana ) grown using alley cropping. Methods: Three de...

Remote sensing can provide good alternatives for traditional in situ water status measurements in orchard crops, such as stem water potential (Ψstem). However, the heterogeneity of these cropping systems causes significant differences with regards to remote sensing products within one orchard and between orchards. In this study, robust spectral indicators of Ψstem were sought after, independent...

Rainfed environments are characterised by unpredictable and highly variable seasonal rainfall and hence highly variable yields. Water use efficiency (WUE, yield per unit of water use) is commonly used for agricultural production with limited water resources. Expertise working towards the water resources need to address the multitudinous aspects in which cropping systems and amounts, timing and ...
