Fertilizer is one of the most important needs for plants. Fertilizing can be done by using inorganic fertilizers or organic fertilizers. Long term fertilizing without adding matter could potentially reduce soil fertility and lead to not optimal growth plant. This study aims determine effect liquid fertilizer (LOF) made from rabbit urine, NPK fertilizer, combination both on bok choy, best dosage...

In the oestrous female cat, fertilization can take place when spermatozoa are introduced into the vagina up to 49 hr after an ovulation-inducing injection of human chorionic gonadotrophin. The spermatozoa require residence in the female reproductive tract before they are capable of fertilizing the eggs in vitro. No eggs were fertilized by freshly ejaculated spermatozoa. One of four oestrous fem...

There are several mechanisms acting in synergism that can impair sperm characteristics of patients with accessory gland infection. In some cases, conventional sperm variables are disturbed with oligo and/or asthenozoospermia. In other patients, these sperm variables may appear normal, but the functional capacity of spermatozoa may be impaired. In particular, changes in the composition of the sp...

the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...
