Despite the well-known benefits of omega-3 (n-3) polyunsaturated fatty acid (PUFA) supplementation on human health, relatively little is known about the effect of n-3 PUFA intake on fertility. More specifically, the aim of this study was to determine how oocyte and preimplantation embryo development might be influenced by n-3 PUFA supply and to understand the possible mechanisms underlying thes...

The effect of clipping management on nitrate (NO3) leaching beneath creeping bentgrass (Agrostis stolonifera L.) has received little attention. The objective of this experiment was to examine the effects of returning grass clippings to creeping bentgrass in combination with N fertilization and irrigation on NO3 leaching. A 30-week long experiment was conducted using fairway-height creeping bent...

ABSTRACT The objective of this study was to evaluate nutrient export, nutritional balance and macronutrient recovery rate in ‘Gigante cactus pear under different fertilization doses, spacings configurations during three production cycles. 72 treatments were arranged a randomized block design with repetitions, two the plots (triple quadruple row), subplots (3.00 x 1.00 0.25 m; 3.00 0.16 m 0.125 ...

OBJECTIVE The aim of this study was to evaluate the influence of maternal age on fertilization, embryo quality, and clinical pregnancy in patients undergoing intracytoplasmic sperm injection (ICSI) using testicular sperm from partners with azoospermia. METHODS A total of 416 ICSI cycles using testicular spermatozoa from partners with obstructive azoospermia (OA, n=301) and non-obstructive azo...

In precise field trials in the Czech Republic the effect of conditions of locality, variety and fertilization on ascorbic acid content (AA) in potato tubers was investigated. From four localities was determined the highest AA content at the locality with the highest temperature average values during both experimental years (by 6.7 to 11.5% in comparison to other localities). Likewise significan...

There is great concern worldwide about air and water pollution arising from N-fertilizer. Considering the expansion of agriculture and fertilization practices in Argentina, the objective of this study was to determine the effect of Nfertilizers on soil N dynamics and then relationship with nitrate concentration in aquifers. Soil samples were taken during a maize crop cycle in two agricultural f...

Abstract Fertilization greatly affects coconut productivity; nevertheless, information on crop nutrition is relatively scarce for in the state of Pará, Brazil. This study evaluated effect fertilization with nitrogen (N), phosphorus (P), potassium (K), and magnesium (Mg) nutritional status yield under edaphoclimatic conditions municipality Moju, Pará State (Brazil). The experiment was conducted ...

The unfertilized ova of Persian sturgeon, Acipencer persicus, were stored in the ovarian fluid at 18 C and fertilized after 0 (control), 3, 6, 9 and 12 hours post stripping using fresh and N pooled sperm obtained from three males. In addition, changes in the osmolality and pH of ovarian fluid during storage were recorded. After 3 h of storage, no significant differences were found between ferti...

The aim of the research was to determine the influence of foliar nutrition with Pentakeep V as well as differentiated nitrogen fertilisation on the content of macro(Ca, K, Mg, Na, P and S) and micronutrients (B, Cu, Fe, Mn and Zn) in spinach leaves. Pentakepp V is a fertilizer containing 5-aminolevulinic acid (5-ALA), which is the direct precursor of chlorophyll in plants. In 2006-2007, a pot e...
