Common bean (Phaseolus vulgar is L.) demand is increasing with an alarming rate around the world, especially in Latin America, Africa, and Asia. Therefore, increased bean yield per hectare i.s the best way to meet the world demand rather than expansion of area under cultivation. The objectives of this experiment were to determine the genotypic variations for green bean and dry seed yield and ma...

The effect of applying plant growth regulators on seed yield and quality of guinea grass (Panicum maximum) cv. Tanzania was studied in one crop on a sandy clay in Mexico. The treatments consisted of 3 growth regulators [ethephon, salicylic acid and a steroidal phytohormone (cidef-4)], 2 stages of application (before seed head emergence and at the beginning of anthesis) and 4 application concent...

In order to study the effect of irrigation interval, N fertilizer and superabsorbent on yield and qualitative traits of sesame (Sesamum indicum L.), a split-split-plot experiment was coducted in a farm in Khusf of Birjand, Iran in 2009 on the basis of a Randomized Complete Block Design. The main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...

Global climate change, especially, increases in carbon dioxide (CO2) concentration and the associated increases in temperature will have significant impact on the crop production. Grain-sorghum [Sorghum bicolor (L.) Moench] cultivar DeKalb 28E was grown at daytime maximum/nighttime minimum temperature regimes of 32/22, 36/26, 40/30 and 44/34 8C at ambient (350 mmol CO2 mol ) and elevated (700 m...

This study was carried out to investigate the yield response of 2 soybean (Glycine max (L.) Merrill) cultivars to different planting dates and plant populations and to examine the relationships of seed yield with leaf area index (LAI) and total dry matter (TDM) during the vegetative and reproductive periods for planting dates, plant populations, and cultivars. Two soybean cultivars, A3127 (earl...

In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207 during the period from December 2008 to April 2009 to study the role of potassium and sulphur on the growth, yield and oil content of soybean (Glycine max var.BARI Soybean-5). The experimental soil was clay loam in texture having pH of 6.3. The experiment included four levels of potassium viz. 0, 20, ...

in this experiment, the possibility of growth promoting of exogenous salicylic acid during two growth stags on chlorophyll content, yield and yield components of canola plant was investigated. for the purpose of improving above traits, salicylic acid was applied in four concentrations (0, 100, 200 and 400 µm) during two different growing stages (first time; when temperature was close to 7-10 °c...
