Soil salinity is one of major deleterious abiotic stress limiting the yield wheat crop. Plant growth produce severely affected by various biotic and environmental metabolic processes. Application Potash fertilizer can reduce harmful effects saline increase crop yield. This research was carried out to evaluate detrimental on suggest appropriate dose potash achieve optimum production under condit...

In order to investigate the effects of deficit nitrogen application on growth and yield in sole cropping and intercropping of canola and pea, a factorial experiment was conducted as randomized complete block design with three replications at Shahrekord University Research Farm, Sharekord, Iran during 2011- 2012 growing season. Five planting ratios (100% canola 66% canola + 33% pea, 50% canola +...

The mechanism associated with improvement of soil nutritional status by oilseed rape crop, leading to better performance of rice crop, in rice-oilseed rape cropping systems is little known. The present study was aimed to test the hypothesis that earthworm casts produced during oilseed rape-growing season have positive effects on grain yield and fertilizer nitrogen (N) utilization in the subsequ...

Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...

Manure application is effective in promoting soil carbon sequestration, but its impact on N2O emission is not well understood. A field experiment was conducted in a maize-cultivated black soil in Northeast China with six treatments: inorganic fertilizer (NPK), 75% inorganic fertilizer N plus 25% pig (PM1) or chicken (CM1) manure N, 50% inorganic fertilizer N plus 50% pig (PM2) or chicken (CM2) ...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
