BACKGROUND Harnessing beneficial microbes presents a promising strategy to optimize plant growth and agricultural sustainability. Little is known to which extent and how specifically soil and plant microbiomes can be manipulated through different cropping practices. Here, we investigated soil and wheat root microbial communities in a cropping system experiment consisting of conventional and org...

The objective of this research was to evaluate the response five wild colocynth (an important medicinal plant) ecotypes toirrigation regime as a basic input cultural practices. laid out in split plot design with three replications. Treatments were two irrigation regimes (Q1= 100 % Etc and Q2= 50 Etc) (G, SF, SD, GD NK). experiment run for seasons (2014 2015). Parameters measured days flowering,...

Soil biological quality can affect key soil functions that support food production and environmental quality. The objective of this study was to determine the effects of management and time on soil biological quality in contrasting dryland cropping systems at eight locations in the North American Great Plains. Alternative (ALT) cropping systems were characterized by greater cropping intensity (...

Accurate geospatial information on the extent of irrigated land improves our understanding of agricultural water use, local land surface processes, conservation or depletion of water resources, and components of the hydrologic budget. We have developed a method in a geospatial modeling framework that assimilates irrigation statistics with remotely sensed parameters describing vegetation growth ...

Multiple cropping systems provide more harvest security for farmers, allow for crop intensification and furthermore influence ground cover, soil erosion, albedo, soil chemical properties, pest infestation and the carbon sequestration potential. We identify the traditional sequential cropping systems in ten sub-Saharan African countries from a survey dataset of more than 8600 households. We find...

A field experiment with the objectives to understand evaluation of mulching effects on weed control in blackgram production under irrigated condition involving two factors viz., (paddy straw mulching, sugarcane trash no mulching) and herbicidal treatments (pendimethalin pre-emergence (PE) @ 1.0 Kg/ha, pendimathalin + Imazethapyr (pre-mix) Valor 32% EC Hand weeding 15 30 days after sowing, weedy...

To better understand cover crop benefits and receive nitrogen scavenging credits for cropping, farmers need simple robust methods of predicting biomass production. A new regulation focused on improving management over 200,000 ha irrigated land in the central coast California motivated us to evaluate if shoot length rye (Secale cereale L., ‘Merced’) triticale (× Triticosecale Wittmack, ‘Pacheco’...

Effects of partial root-zone irrigation (PRI) on the hydraulic conductivity in the soil-root system (L(sr)) in different root zones were investigated using a pot experiment. Maize plants were raised in split-root containers and irrigated on both halves of the container (conventional irrigation, CI), on one side only (fixed PRI, FPRI), or alternately on one of two sides (alternate PRI, APRI). Re...

Rajasthan is the largest state of India in terms area, it accounts for 5.67% total population India, whereas this has only 10.4% geographical area. There are 7 divisions and 33 districts Rajasthan. Agriculture allied activities play an important role economy state, although its contribution to NSDP continuously declining, yet agriculture sectors form backbone state's economy. Change cropping pa...

the main objective of this research is to determine water use efficiency (wue) of some major crops under farmer's management in the different region of iran including kerman, hamedan, moghan, golestan and khuzestan provinces. the research also attempted to assess and identify the sources of inefficiencies in improving wue. based on methodology, wue was determined by measuring crop yield (k...
