Background: Direct sowing technique is considered a promising tool for reducing costs and increasing species diversity in restoration projects. However, several factors can limit its success, making it necessary methodological adjustments to be made order maximize the emergence, establishment initial growth of plants. This study aimed evaluate influence use fungus Trichoderma asperelloides hydr...

introduction bean is one of the most important legumes worldwide for direct human consumption and is a rich source of protein and carbohydrates. bean is weak to compete with weed because of the retard growth at the early stages. therefore, weed control at this time plays an important role to gain high priduction. yield crop depends on weed number, and size after germination. weed control depend...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

to evaluate the effects of on-farm seed priming treatments and sowing dates on rate and percentage of seedling emergence, biological yield and some physiological indices of corn hybrid (sc. 260) an experiment was conducted in hamedan, iran in 2010. a split plot in a randomized complete block design with three replications was conducted. main plots include three sowing dates (early, on-time and ...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...

Phosphorus (P) is the second most important crop nutrient after nitrogen that increases productivity and profitability of maize (Zea mays L.) on P deficient soils in Northwest Pakistan. The objective of this study was to find the best level and time of P application for higher maize (cv. Azam) productivity and profitability. Field experiment was conducted at the Research Farm of Khyber Pakhtunk...

The usefulness of 3 herbicides and flame weeding in lemon balm sown directly into the field was assessed a two-year experiment. Glufosinate-ammonium (600 g∙ha–1) (90 kg propane∙ha–1) were applied 12–13 days after sowing, i.e. shortly weed emergence 4 before crop emergence. Bentazon (960 fluazifop-P-butyl (150 sprayed approximately weeks during balm, when weeds cotyledon – 2–4 true leaves stage....
