ABSTRACT Cowpea plants produce protein-rich grains and present high yield potential when grown under irrigation and organic fertilization, enabling to substitute part of the mineral fertilizer with sewage sludge, reducing costs and generating environmental benefits. Thus, a field study about residual effect of sewage sludge fertilization on cowpea was developed to evaluate this substitution.

A substrate culture experiment was conducted to study the effect of different biological organic fertilizer levels (control: zero fertilization, low level, medium level and high level) on plant growth and yield of Chinese kale (Brassica alboglabra Bailey).

Thus they promoted plant growth. The fertilizer utilization ratio of Chinese kale was the lowest for low fertilization treatment, and it was the highest for

Using a predator-prey model and realistic parameter values, iron fertilization was found to only cause temporary blooms up to 5 months in duration, and relatively small increases in adsorption of atmospheric CO2.

HighlightsNUE response to N addition is dependent on N source (fertilizer, manure, and biological fixation).Random forest models captured 71% and 47% NUE variance for CONUS and global croplands.Contribution from biological N fixation was most important for explaining NUE variance, followed by manure and fertilizer contributions.ABSTRACT. Nitrogen use efficiency (NUE) is a useful indicator of the tradeoffs among cropland harvest nitrogen (N) and total N fertilization. Total N fertilization can be fulfilled by different sources depending on local availability, livestock production, land use and

Abstract:

Fertilization plays a crucial role in ensuring global food security and ecological balance. This study investigated the impact of substituting innovative biological manure for chemical fertilization on rice (Oryza sativa L) productivity and soil biochemical properties based on a three-year experiment. Our results suggested rice yield and straw weight were increased under manure addition treatment. Specifically, 70% of total nitrogen (N) fertilizer substituted by biological manure derived from straw, animal waste and microbiome, led to a substantial 13.6% increase in rice yield and a remarkable

Abstract:

Fertilization is a key factor for sustaining productivity in agroecosystems. A long-term experiment in cambisol following periodical application of several types of fertilization has been running at the experimental site since 1954. In this study, we determined the impact of applied inorganic and/or organic fertilizers on the activity of soil enzymes and on the structure of microorganisms at depths of 0–30 cm and 30–60 cm. Single-factor comparison showed that use of inorganic and/or organic fertilizer had an insignificant effect on the activities of soil enzymes (at depths 0–30 cm and 30–60 cm

Abstract:

Before fertilization, spermatozoa must undergo a process called capacitation in order to fulfill their fertilization potential. This includes a series of structural, biochemical, and functional changes before a subsequent acrosome reaction and fusion with the oocyte. However, low temperatures during cryopreservation may induce a premature activation of capacitation-like changes, also known as cryocapacitation, immediately after thawing, which may lead to a decreased viability, motility, and fertilization ability of cryopreserved spermatozoa. Furthermore, cryopreservation is responsible for the

Abstract:

Crops of faba beans (Vicia faba cv.

The frequency of pollination ranged from 89.8 to 99.6% over crops, with an overall mean of 96.8%. Pistil fertilization varied from 88.4 to 99.1% about a mean of 95.5%; overall, 82.2% of all ovules examined were fertilized. There was no significant main effect of flower position in the raceme, although there were significant crop x floral position effects on fertilization. Mean ov

Abstract:

In species where males express carotenoid-based sexual signals, more intensely coloured males may be signalling their enhanced ability to combat oxidative stress. This may include mitigating deleterious oxidative damage to their sperm, and so be directly related to their functional fertility. Using a split-clutch in vitro fertilization technique and dietary carotenoid manipulation, we demonstrate that in non-competitive fertilization assays, male three-spined sticklebacks ( Gasterosteus aculeatus ) that are fed higher (but biologically relevant) levels of carotenoids had a significantly increa

Abstract. While nutrient depletion scenarios have long shown that the high-latitude High Nutrient Low Chlorophyll (HNLC) regions are the most effective for sequestering atmospheric carbon dioxide, recent simulations with prognostic biogeochemical models have suggested that only a fraction of the potential drawdown can be realized. We use a global ocean biogeochemical general circulation model developed at GFDL and Princeton to examine this and related issues.

Abstract:

In sexual reproduction, two gamete cells (i.e., egg and sperm) fuse (fertilization) to create a newborn with a genetic identity distinct from those of the parents. In the course of these developmental processes, a variety of signal transduction events occur simultaneously in each of the two gametes, as well as in the fertilized egg/zygote/early embryo. In particular, a growing body of knowledge suggests that the tyrosine kinase Src and/or other protein-tyrosine kinases are important elements that facilitate successful implementation of the aforementioned processes in many animal species.
