We examined the effects of the sowing time on the yield production and oil content of the sunflower hybrids in 2010 and 2012. The crop year and the sowing time had both a strong impact on the yield, on the oilcontent and yield. By delaying the sowing time both the yield crop result and the oil yield increased. In 2010 in terms of crop yield and oil yield results PR64H42 was the best, in 2012 NK...

Seeds of Balanites aegyptiaca stored for one year were germinated using cold and boiling water pre-treatments and different sowing orientations. Whole fruits were soaked in cold water for (18, 24 and 48 hours, respectively), while extracted sun dried seeds were immersed in boiling water for 7 minutes. Seeds of each treatment were sown in three orientations (seeds laid vertically with stalk end ...

Baccharis dracunculifolia DC. is a pioneer plant native from Brazil that has great importance due to its secondary metabolites (essential oil and Brazilian green propolis) potential in the recovery of degraded areas. The main goal this study was evaluate propagation techniques B. by sexual reproduction asexual male female stem cuttings. For reproduction, individuals natural population were peri...

Conventional methods of weed control are weather dependent, costly and labour intensive. Indiscriminate use of chemicals for controlling weeds may pose environmental problems. Sorghum allelopathy is a new technique, which has been tested for controlling weeds of wheat (Triticum aestivum L.) as a substitute for chemical herbicides to reduce environmental pollution. Mature sorghum herbage contain...

Native plants of the Sahara are remarkably resistant to prolonged droughts and important sources forage, food, medicine. Their regeneration from seeds after strong anthropogenic disturbances is a challenging step toward their conservation mitigate desertification. We studied germination responses 43 dominant native species desert that could be propagated for future ecological restoration projec...

The aim of this study was to evaluate the effect of pre-treatments on overcoming dormancy of A. coriacea seeds. Seeds were processed and stored in polyethylene bags at temperatures of at -18°C (42% RH), 5°C (34% RH), 15°C (60% RH) and 25°C (34% RH), during 0, 30, 60, 90, 120 and 150 days. After storage, seeds were immersed in 350 mg.L-1 gibberellic acid for 144 hours. Sowing was carried out in ...

In women, it is known to cause anovulation, sub-fecundity, increased risk of fetal anomalies and miscarriage rates. However, in women going for assisted reproduction the effects of obesity on egg quality, embryo quality, clinical pregnancy, live birth rates are controversial To assess the effect of women's...

Mulching and nitrogen are critical drivers of crop production for smallholders of the Loess Plateau in China. The purpose of this study was to investigate the effect of mulching and nitrogen fertilizer on the soil water content, soil nitrate-N content and vertical distribution in maize root-zone. The experiment was conducted over two consecutive years and used randomly assigned field plots with...

Brazil has 180 Mha of pastures, 86 occupied with Urochloa spp. (syn. Brachiaria), and 70% in some level degradation. Inoculation plant-growth-promoting bacteria (PGPR) may represent an economic environmental feasible strategy to improve pasture production. Two greenhouse seven field trials were performed verify the effects seed inoculation at sowing or leaf-spray established pastures elite stra...
