Phenotypic diversity among maize landraces is obvious in kernel color, ear and kernel shape and size, and agronomic traits such as plant height and length of the growing cycle. Traditionally, this phenotypic diversity has been used to classify populations into “races.” Currently, 59 races of maize have been described in Mexico. According to DNA analyses, these races are organized as a continuum...

• Seed-borne bacteria is an essential source of the plant microbiome. Maize seed germination modulates ecological succession for seed-borne microbiota. Seed-bacteriome abundance taxa in germinated maize seeds. influence and growth maize. Seed microbiome acts as a “bacterial barrier” against phytopathogens. seed-bacteria community var DKB177 protect Penicillium sp. fungus. Seeds are reservoirs b...

As an extremely important staple food throughout East and Southern Africa, maize (Zea mays) has been a primary focus of agricultural research on the continent during and since the Green Revolution. Despite the development of higher yielding varieties (HYVs) and improved cultivation methods, Kenya has yet to attain self-sufficiency in the crop's production and is a regular importer of grain and ...

Seed priming with hormones has been an efficient method for increasing seed vigor as well as seedling growth under stressful conditions. These responses have in the past been attributed to the activation of antioxidant systems in a range of crops. The results described in this work show that hormonal priming with methyl jasmonate, salicylic acid or CEPA (chloroethylphosphonic acid), an ethylene...

canistel (pouteria campechiana) is an underutilized fruit tree species found in many parts of the world. the objective of this study was to evaluate suitability of canistel fruit meal (cfm) as a feed ingredient for broiler chickens. giving completely randomize design, ninety broiler chickens in 30 floor pens received one of five diets ad libitum from day 21 to 42. the nutritionally balanced con...

Mexico, the center of origin of maize (Zea mays L.), has taken actions to preserve the identity and diversity of maize landraces and wild relatives. Historically, spatial isolation has been used in seed production to maintain seed purity. Spatial isolation can also be a key component for a strategy to minimize pollen-mediated gene flow in Mexico between transgenic maize and sexually compatible ...

BACKGROUND: Overuse of fertilizers can lead to groundwater contamination, depletion of soil microorganisms and beneficial insects, increased crop susceptibility to diseases, acidification or alkalization of soil, damage to soil structure, reduced organic matter and soil fertility. Therefore, for achieve sustainable agricultural, it is necessary to reduce the consumption of conv...

In the present study the mould incidence, ergosterol and aflatoxin B1 (AFB1) contaminations were evaluated in different food based seed samples viz., chickpea, cowpea, green gram, groundnut, Indian bean, maize, sorghum, soya bean and sunflower collected from different agro-climatic regions of Karnataka (India). The agar plate and standard blotter methods were employed for determination of the f...

Stratospheric ozone depletion has caused an increase in the amount of ultraviolet-B (UV-B) radiation reaching the earth's surface. Numerous investigations have demonstrated that the effect of UV-B enhancements on plants includes reduction in grain yield, alteration in species competition, susceptibility to disease and changes in plant structure and pigmentation. Many experiments examining UV-B ...

A pronounced residual effect of organic and inorganic fertilizers, applied in maize crop was observed on yields of maize-gobhi sarson cropping system. The experiment was conducted with 10 treatments of N, P, K, FYM, crop residue and zinc sulphate nutrients. The highest growth, yield and yield components of maize crop were recorded with 100% recommended fertilizer dose-RFD + ZnSO4 20 kg/ha and t...
