drought, high and low tempratures are the most important abiotic stresses in chickpea cultivation. improving plant root characteristics (root length and root volume) is one of the ways to increase drought tolerance in chickpea. mycorrhizal symbiosis increases drought resistance of host plants through different mechanisms. to study the effects of water stress and mycorrhizal fungi inoculation on...

Reducing tillage and growing cover crops, widely recommended practices for boosting soil health, have major impacts on soil communities. Surprisingly little is known about their impacts on soil microbial functional diversity, and especially so in irrigated Mediterranean ecosystems. In long-term experimental plots at the West Side Research and Extension Center in California's Central Valley, we ...

Excessive or N-based application of poultry manure for crops may result in significant risk of P loss with surface runoff. This study assessed P loss immediately after poultry manure application to soybean [Glycine max (L.) Merr.] residue with and without tillage at eight Iowa fields. Manure from chickens (Gallus gallus domesticus) or turkeys (Melleagris gollopavo) was applied at intended rates...

Efficacy of some synthetic and biopesticides against pod borer, Helicoverpa armigera (Hubner) damage in chickpea was studied at the Regional Agricultural Research Station, Ishurdi, Pabna, Bangladesh during rabi cropping season of 2004-05. Synthetic and biopesticides reduced pod borer damage significantly. Significantly lowest pod damage was observed in cypermethrin (5.75%) and HNPV (5.86%) spra...

the objective of this study was to determine the quicker response of subsoil or surface soil to minimum tillage (mt) and conventional tillage (ct) and biofertilizers (bacillus coagulans, b), phosphorus fertilization (p) and integrated p and b (pb) under the wheat (triticum aestivum l vr. sardari) growing season. the experimental design was split plot laid out in randomized complete block design...

This study evaluates the watershed-scale effects of non-point-source (NPS) pollution loads caused by rice straw mulching and no-tillage applications in upland crop areas using the Hydrological Simulation Program–Fortran (HSPF) model. The study area is the Byulmi-cheon watershed (1.21 km2) of South Korea. Hourly rainfall, discharge and stream water quality data were collected for three years (20...

The study on the lateral movement of soil organic carbon (SOC) during soil erosion can improve the understanding of global carbon budget. Simulated rainfall experiments on small field plots were conducted to investigate the SOC lateral movement under different rainfall intensities and tillage practices. Two rainfall intensities (High intensity (HI) and Low intensity (LI)) and two tillage practi...

The effects of reduced tillage and lime on crop yield and soil physical and microbial properties were studied in a weakly-structured silty clay loam soil. Two autumn primary tillage practices were compared, mouldboard ploughing to 20–25 cm and cultivation to 12 cm. Seedbed preparation was carried out by several harrowing operations in the mouldboard ploughed treatment, and with a PTO-driven har...
