Effect of plant density and nitrogen fertilizer on growth, yield and fruit quality of sweet pepper (Capsicum annum L.)

The present research was carried out to evaluate response of sweet pepper (Capsicum annum L.) to plant density and nitrogen fertilizer under field conditions. Plant density at four levels (2050 cm, 3050 cm, 20100 cm and 30100 cm) and nitrogen treatments at four levels (0, 50, 100 and 150 kg N/ha) were applied. Plant height, lateral stem number, leaf chlorophyll content, yield, and vitamin C were assessed at...

Biological hydrogen production from acid-pretreated straw by simultaneous saccharification and fermentation

  Hydrogen is currently produced in large amounts in the chemical industry, including that from the steam reforming of fossil fuels. Hydrogen must be produced sustainably to be economically feasible. This could be achieved from water through electrolysis powered by photosynthetic or other renewable energy, or by gasification or pyrolysis of biomass. It may also be possible to develop a cost-effective and...

Construction of a proteomic reference map for analysis of development of etiolated rice seedlings

  When rice seedlings grow in darkness, they will be yellow in color and show typical etiolated characters such as elongation of hypocotyls and stem, rolling up of young leaves around the stem tip. To better understand the development of etiolated rice seedlings at the molecule level, a proteomic reference map of etiolated rice seedlings was established by combining Two-Dimensional Gel...

Scaling out best fit legume technologies for soil fertility enhancement among smallholder farmers in Malawi

  Maize (Zea mays L.) is a major staple food in Malawi. However, low soil fertility resulting from low and inappropriate use of fertilizer practices, continuous monocropping and inappropriate crop residues management coupled with limited resources and droughts keep yields low. This had led to a quest for sustainable solutions such as maize-legume intercropping or rotation including more efficient use of...

Characteristics of soil CO2 fluxes and N2O emission in a winter wheat ecosystem under enhanced UV-B radiation

  Field experiments were conducted during the 2007 to 2008 winter wheat-growing season to investigate the influence of enhanced UV-B radiation on diurnal variations in soil CO2 fluxes and nitrous oxide (N2O) emissions from a winter wheat ecosystem. CO2 and N2O fluxes were measured by static opaque chamber-gas chromatograph technique. Results showed that on sunny days, soil CO2 fluxes and N2O...

Characterization of soils affected by salts in irrigation district 110 “Río Verde”, Oaxaca, Mexico

The central soils of the Irrigation District 110 Río Verde, Oaxaca, Mexico, present salt accumulation problems in the upper layers. This study evaluated some of their physicochemical characteristics, levels and type of salinity. In the dry season soil samples were collected from five randomly established profiles. These are alluvial soils at around 2.0 m depth, derived from weathered metamorphic rocks; silty...

Effect of sulphur fertilizer on sulphur uptake and forage yield of Brassica juncea in condition of different regimes of irrigation

To study the effect of irrigation and sulphur on Indian mustard, a field experiment was conducted at Indian Agricultural Research Institute, New Delhi during crop season of 2007-2008 and 2008-2009. The experiment was carried out in split plot design with three replications. The treatments consisted of three levels (no irrigation, one irrigation at 45 days after sowing (DAS) and two irrigations at 45 DAS and 90 DAS) of...

Interactive effects of water and nitrogen supply on growth, biomass partitioning, and water-use efficiency of young apple trees

  Drought and low concentration of soil nitrogen (N) limit crop growth and production in arid and semi-arid regions. Improving the efficient use of these limited resources is an important challenge. We tested one-year-old trees of three apple cultivars (Malus domestica cv. ‘Golden Delicious’, ‘Naganofuji No. 2’, and ‘Pink Lady’) grafted on M. hupehensis to...

Differences in yield parameters of emmer in comparison with old and new varieties of bread wheat

  Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different...

Arbuscular mycorrizal fungi associated with Theobroma cacao L. in the region of Yamoussoukro (Cote d’Ivoire)

  Arbuscular mycorrhizae are the most widespread plant symbiosis on earth. This symbiosis is well-known for its positive impact on cultivated plant yields. Cocoa (Theobroma cacao) plays an important role in the economic prosperity of Côte d’Ivoire. However, cocoa yields remain low due to a loss of soil fertility and pest and disease damages. The myccorhizal symbiosis could be a way of resolving...
