to survey the effects of chemical and biological phosphorus on the yield and essential oil of satureja hortensis l. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at research station of faculty of agriculture, urmia university in 2011. the treatments were chemical phosphorus fertilizer with four levels (0, 50, ...

A study was carried out in the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Old Brahmaputra Flood Plains Soil (AEZ-9) during December 2001 to April 2002 to find out the effect of seed rates and NPK levels on dry matter accumulation and grain yield of foxtail millet (Setaria italica L. Beauv.). Four seed rates viz., 8,10,12, and 14 kg/ha and five levels of NPK ferti...

A field experiment was conducted on the Effect of phosphorus fertilizer and seed rates growth yield common bean (Phaseolus vulgaris L) at Farm agriculture faculty Kunduz University during spring season 2023 to determine optimum for maximum in northeast Afghanistan (Kunduz province). The treatment consists three levels (0kgP2O5ha-1, 40kgP2O5ha-1 80kgP2O5ha-1) four combined (125 kgha-1, 150 175 k...

Vernonia galamensis Cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. The experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of Vernonia galamensis Cas.The experiment was conducted for two years during 2014-2015 on experimental field of Wondo Genet Agricultural research center,...

Effects of seed rates on grain, straw and oil yield of safflower (Carthamus tinctorius L.) were studied for two years in the semi-arid central Bekaa Valley of Lebanon. Three trials, two under rainfed and one under supplementary irrigations, were conducted using seed rates of 6, 12, 24 and 48 kg ha -1 corresponding to intra-row spacing of 20, 10, 5, and 2.5 cm, respectively. There was significan...

the effects of plant densities (25, 35 and 45 plants m-2 as d1, d2 and d3 respectively), and inoculation with rhizobium bacteria (without rhizobium, with rhizobium and rhizobium + microelement application), on growth and yield were studied in chickpea (cicer arietinum l.). experiment was carried out in 2008 at research farm of the faculty of agriculture of university of mohaghegh ardabil, a fac...

Background: Blackgram (Vigna mungo L.) is an important short duration crop and grown throughout the country. Seed treatment can improve seedling establishment better stand; it also improves plants ability to tolerate stress at early growth stages foliar application has advantage of quick efficient utilization nutrients, elimination nutrient losses through leaching fixation in soil helps regulat...

Field and laboratory experiments were conducted to assess the response of wheat external auxin application nitrogen. Studied factors in field experiment different concentrations (0, 50, 100 ppm) nitrogen fertilizer 75, 150 kg/ha). In experiment, germination traits produced seeds from maternal plants under treatments assessed. Results showed that no with had higher stem leaf yield than 50 ppm kg...

in order to study the effects of manganese sulfate in increasing seed yield of four safflower genotypes (carthamus tinctorius) under rainfed conditions, this experiment carried out in maragheh agricultural research station. the experiment was arranged with four mn fertilizer levels (0,10,20,30 kg ha-1) as soil application together with two foliar spray levels (1% and 2%) of 1.5 kg ha-1 manganes...

background and objectives: drought stress is one of the most important environmental factors reducing growth and yield of crops, especially in arid and semiarid regions of the world. during drought stress, nutrient uptake diminishes due to rising of solute concentrations and so increasing of osmotic potential in the root zone. with increasing soil ph, micronutrient uptake decreases more than ot...
