fertility Quantity

After getting pregnant by in vitro fertilization (IVF), pregnancy loss is one factor that prevents the baby from being born. An estimated 80% of pregnancy loss occurs in the first trimester, which is higher than in the natural pregnancy. The reason is said to be that the age of women receiving fertility treatment is often higher, leading to ovarian reserve, and decreased oocyte quantity and quality.

The results show that the increase in the number of years of education for women has significantly reduced the number of births of their lifetime children, especially the number of boys. Finally, this article expounds the mechanism of the changes in female education and birth from three aspects: age at first marriage and unmarried rate, number of boys giving birth and contraceptive rate.

The detection of quantitative trait loci has accelerated with recent developments in genomics. The introduction of genomic selection in combination with sequencing efforts has made a large amount of genotypic data available. Functional traits such as fertility and calving traits have been included in routine genomic estimation of breeding values making large quantities of phenotypic data available for these traits. This data was used to investigate the genetics underlying fertility and calving traits and to identify potentially causative genomic regions and variants.

Fertilizers are one of the costly inputs but continue to exert significant contribution to produce additional food grains. To realize maximum benefits and reduce nutrient losses from fertilizers, they must be applied in the right quantity, source and combination at the right time using the right method.

Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols.

Soil testing is a useful tool that can help to ensure the efficient use of applied plant nutrients. Soil tests measure the quantity of a nutrient that is extracted from a soil by a particular extractant. The measured quantity of extractable nutrient in soil is then used to predict the crop yield response to application of the nutrient through fertilizer, manure and any other amendments. As soil test levels increase for a particular nutrient, the expected crop yield response to additions of that nutrient decreases.

Supply of good quality and adequate quantities of fodder play an important role in improving the health and productivity of animals. Green and dry fodders are cheaper sources than concentrate feed, hence its inclusion would curtail the cost of feed purchase. Unfortunately, in our country there is acute scarcity of green and dry fodder mainly due to very less area available for its cultivation. In future also there are less chances to increase area under forage cultivation because of heavy pressure of burgeoning human and livestock population on meager land.

India is facing various challenges in agriculture sector for sustaining soil fertility and food grains production, besides environmental degradation and food security of the country in the event of ever increasing demands of food grains production with limited cultivable land. Cultivable land and maintaining its soil fertility are one of the major tasks which supports about 17.6% of its population and leads to fact that, our natural resources are under considerable strain. Food grains are a major source of energy and are thus are vital for food and nutritional security.

Plant nutrition plays a major role in quantitative and qualitative crop production in bringing sustainability and plants require seventeen essential elements for their normal growth and development. Among these, those elements required smaller in quantity is called micronutrients (Fe, Cu, Zn, Mn, B, Cl, Mo and Ni). Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants.

Finger millet or Ragi is one of the most important minor millet abundantly grown in southern parts of Karnataka. It plays a significant role in livelihood of small and marginal farmers in Ramanagara district of Karnataka, South India. Farmers generally follow traditional sowing method in Ragi using bullock drawn seed drill where uniformity in spacing and depth cannot be maintained. Quantity of seeds required for sowing is also more in this traditional method.

Agriculture is going through a profound revolution worldwide due to increasing world demand for food, higher costs of energy and other inputs, environmental pollution problems, and instability of cropping systems. The importance of plant functioning can be realized from the facts that knowledge of mineral nutrition of plants has opened new vistas for fertilizer practices. The detection of deficiencies and toxicity of particular mineral nutrient element has enabled us to make adequate soil amendments and root nutrient absorption for better plant growth.
