The study presents the results of a 3-year field trial aimed at assessing yield and quality raw material for ensiling in cultivation three maize varieties differing their agronomic genetic profile, conditioned by selection nitrogen fertilizer. Maize cultivar ES Metronom showed significant advantage over other cultivars when fertilized with UltraGrain stabile, or alternatively Super N-46. applic...

Abstract The study was carried out during the growing season 2022 in one of orchards located Al-Sajla area / Al-Khairat district Holy Karbala governorate On seed Sidr varieties two years old. To find effect immersing bait pens, an apple cultivar treated with a combination growth regulators three concentrations (0, 40 + 20, 80 mg.L -1 ) and symbol (A0, A1, A2) sequence, addition Optimus Pius nan...

Preventive and/or manipulative practices will be needed to maintain soil's biological, physiochemical, nutritional, and structural health in natural, managed, and disturbed ecosystems as a foundation for food security and global ecosystem sustainability. While there is a substantial body of interdisciplinary science on understanding function and structure of soil ecosystems, key gaps must be br...

monly used instruments is a Minolta SPAD (soil plant analysis development) meter. The SPAD meter measures the difference in light absorption at 430 and 750 nm (Wood et al., 1992). The former is the transmittance peak for chlorophyl ‘a’ and ‘b’, and the latter is in the near-infrared region. The instrument converts the difference in light absorption at these two wavelengths into a numerical SPAD...

in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...

Sweet potato [Ipomoea batatas (L) Lam] yields currently stand at 4.5 t ha-1 on smallholder farms in Uganda, despite the attainable yield (45-48 t ha-1) of NASPOT 11 cultivar comparable to the potential yield (45 t ha-1) in sub-Saharan Africa (SSA). On-farm field experiments were conducted for two seasons in the Mt Elgon High Farmlands and Lake Victoria Crescent agro-ecological zones in Uganda t...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria(pgpr) on yield and yield components of chickpea (cicer arientinum l.) arman cultivar. this research was conducted as split plot based on randomized complete block design at zanjan university researchal farm. irrigation levels(optimum irrigation during season growth and no irrigat...

siahe-e-samarghandi is one of the most important cultivars of grapevine (vitis vinifera) in fars province. some problems of this cultivar are its sparse clusters with small berries and berries that are in different stages of growth. foliar application of urea, zinc sulfate, boric acid 4, 3 and 1gl-1, respectively as well as sodium molybdate at the concentrations of 0, 0.5, 1 and 1.5 gl-1 were a...

The study was conducted to observed the effects of Organic fertilizer and EM1on growth yield two lettuce cultivars in greenhouse conditions during 2011 growing season. experiment performed by Randomized Complete Block Design (RCBD) consisted four levels EM1 (0, 500, 1000, 1500) ml.l-1, (without with fertilizer) (Syrian Local cv.). results showed that cultivar Syrian significantly increased plan...
