In vitro fertilization
is an assisted reproductive technology (ART), which involves retrieving eggs from a woman's ovaries and fertilizing them with sperm outside the body, in vitro.
with P 35 kg*ha-1 and K 100 kg*ha-1 was applied prior to sowing.
Improper in vitro fertilization
includes sperm injection from ex-husbands or donors other than spouses.
In addition to increasing sperm numbers, the likelihood of fertilization
can depend on gamete traits.
"As for state quotas, then 1,500 children were born after in-vitro fertilization
with state support.
IVF is a fertilization
technique where the embryo is conceived in a test tube and implanted in a woman's uterus.
By transmitting the genetic information to the next generation and marking the beginning of a new life, the encounter between female and male gametes at fertilization
is one of the most fundamental processes in biology.
The recommendation of nitrogen fertilizations
in cover aiming to increase its efficiency has become routine practice in the fertilization
management of the rice crop.
Yield responses to fertilization
were ranked as NPK>NP>NK>PK, illustrating that N was the most limiting nutrient in rapeseed productivity following P and K.
Updated recommendations of rice fertilization
are available and can be accessed freely by farmers.
The experiment was set in randomized blocks with twelve treatments arranged in a 3 x 4 factorial scheme with three replicates, corresponding to three planting spacings: single row, 1.00 x 0.50 m; single row, 2.00 x 0.25 m and double row, 3.00 x 1.00 x 0.25 m, all with population of 20,000 plants [ha.sup.-1], and four combinations of fertilization
(regional use): without chemical fertilization
; phosphate fertilization
(P), at the dose of 150 kg [ha.sup.-1] of [P.sub.2][O.sub.5]; nitrogen and phosphate fertilization
(NP) at the doses of 200 kg [ha.sup.-1] of N and 150 kg [ha.sup.-1] of [P.sub.2][O.sub.5]; nitrogen, phosphate and potassium fertilization
(NPK), at the doses of 200 kg [ha.sup.-1] of N, 150 kg [ha.sup.-1] of [P.sub.2][O.sub.5] and 100 kg [ha.sup.-1] of [K.sub.2]O.
