This document discusses antitranspirants and their effects on crops. It defines antitranspirants as compounds that reduce water loss through transpiration without significantly impacting plant growth or photosynthesis. There are four types of antitranspirants: stomatal closing, filmforming, reflecting, and growth retardants. The document provides examples of how antitranspirants have been shown to improve wheat, maize, barley and soybean yields under drought conditions by reducing water loss from the plants. However, it also notes that antitranspirants can potentially reduce photosynthesis and increase leaf temperatures if used.Essential nutrients for plants, their function and deficiency symptoms 1

Seed dormancy allows seeds to remain dormant during unfavorable conditions until conditions become suitable for germination. There are two main types of dormancy - primary and secondary. Primary dormancy occurs due to internal factors like hormones, while secondary dormancy is caused by external factors like temperature. Dormancy can be overcome through methods like scarification, stratification, hormone treatment, and photoperiod manipulation. Seed dormancy provides important biological benefits like survival during drought or frost and dispersal to new areas.Essential plant nutrients,ppt

EFFECT OF MOISTURE STRESS ON PLANT GROWTH AND DEVELOPMENTSHRAVAN KUMAR REDDY
油
Moisture stress can negatively impact plant growth and development through various mechanisms. Crops have developed different adaptations to moisture stress including escaping drought through short lifecycles, avoiding stress through water conservation or improved uptake, and tolerating stress. Avoiding stress involves mechanisms like reducing leaf area, increasing waxiness, and regulating stomata to conserve water or developing deep, branched root systems and high root to shoot ratios to improve water uptake. Tolerating stress includes osmotic adjustment to maintain turgor under water deficits. Understanding crop adaptations is important for managing plants under moisture stress conditions.Nursery management part 2

Soil textureDr.Khalid Khan
油
Soil texture refers to the relative proportions of sand, silt, and clay particles in soil. Soil texture determines how much water the soil can hold and how quickly it can infiltrate. Sandy soils have the largest pore sizes and highest infiltration rates since water can flow freely between particles. Sand is defined as particles between 2-0.02 mm, silt between 0.02-0.002 mm, and clay less than 0.002 mm.

SUMMARY
Based on human relationship with bacteria, virulence is one of the most important case to us. Some forms of virulence thought to arise only from the actions of bacteria are not actually caused by them but are indirectly influenced by another counterpart in the microbial mix of the ecosystem called bacteriophage; viruses that only infect prokaryotes such as bacteria but not eukaryotes. Bacteriophages preferably attack bacteria due to the lack of specific receptors for phages on eukaryotic cells which are found in bacteria e.g. peptide sequences and polysaccharide moieties in gram positive and gram negative bacteria, bacterial capsules, slime layers, flagella etc. They recognize and bind to bacteria using appropriate receptors, subsequently proceeding to inject their genome called prophage into their host. This review focuses on the most probable outcomes of phage-host interactions via the lytic and lysogenic cycles which are therapeutic effect and pathogenicity/resistance to antibiotics respectively. By lysogenic conversion or transfer of acquired genetic materials via transduction, phages can confer unusual traits such as virulence and antibiotics resistance. Important pathogenic bacteria that cause persistent and critical infections which have their pathogenicity engineered by phages include Pseudomonas aeruginosa, Salmonella enterica, Escherichia coli, Vibrio cholerae, Staphylococcus spp., and Clostridium spp.
The prophages influence their virulence in a variety of ways which include: contribution to the production of phage-encoded toxins, modification of the bacterial envelope, mediation of bacterial infectivity, and control of bacterial cell regulation. The unwavering threat of antimicrobial resistance in global health, extreme difficulty involved in developing novel antibiotics, and the rate at which microorganisms develop resistance to newly introduced antimicrobials have sparked urgency and interest in research for effective methods to eradicate pathogenic bacteria and limit antibiotic resistance. As a result, interest in phage therapy has been reignited because of the high efficiency in detecting and killing pathogenic bacteria by phages.

Protein degradation via ubiquitous pathway In general science, a ubiquitous pathway refers to a biochemical or metabolic pathway that is:
1. *Widely present*: Found in many different organisms, tissues, or cells.
2. *Conserved*: Remains relatively unchanged across different species or contexts.
Examples of ubiquitous pathways include:
1. *Glycolysis*: The process of breaking down glucose for energy, found in nearly all living organisms.
2. *Citric acid cycle (Krebs cycle)*: A key metabolic pathway involved in energy production, present in many cells.
3. *Pentose phosphate pathway*: A metabolic pathway involved in energy production and antioxidant defenses, found in many organisms.
These pathways are essential for life and have been conserved across evolution, highlighting their importance for cellular function and survival.

Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins.
Pigs are amenable to many different styles of farming: intensive commercial units, commercial free range enterprises, or extensive farming (being allowed to wander around a village, town or city, or tethered in a simple shelter or kept in a pen outside the owner's house). Historically, farm pigs were kept in small numbers and were closely associated with the residence of the owner, or in the same village or town.[1] They were valued as a source of meat and fat, and for their ability to convert inedible food into meat and manure, and were often fed household food waste when kept on a homestead.[2] Pigs have been farmed to dispose of municipal garbage on a large scale.[3]
All these forms of pig farm are in use today, though intensive farms are by far the most popular, due to their potential to raise a large amount of pigs in a very cost-efficient manner.[4] In developed nations, commercial farms house thousands of pigs in climate-controlled buildings.[5] Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods,[6] cosmetics,[7] and medical use.[8]Pig farming has gained importance today. Pigs have inherited capacity to acclimatize with varying climatic conditions. Pigs cannot withstand high temperature climate.
Pigs are adjusted to varied rearing practices and consume different types of food (Omnivorous) to attain higher growth and meat production.
Pigs will attain 60-70kg body weight in 6-8months period.
Female pigs i.e., sows will come to heat at age of 8-9 months but avoid using male pigs (Boars) for breeding purpose until it attains one year of age.
Adult sows when bred during right time after attaining maturity will farrow 8-12 piglets in 112-118 days of gestation period (i.e., about 4 months of gestation). Feedefficiencyis to gain one Kg live weightfor every 2.75-3kg feed consumed (FCR: 1:2.75). There are many advantageous in pig rearing. Pork is available at a cheaper price with nutritious and highly palatable tasty meat of higher quality animal protein. Pig bones are used for producing bone meal and also used for purification of sugar in sugar industry.
The manure droppings and urine are good fertilizers which enhance the soil fertilityand improve grain production.
Pig hairs (Bristles) are used for making brushes and ropes, hooves are used for shirt button making and preparation of gum. Hence, pigs are called as multi utility domestic animals. Farmers can take up piggery farming and reduce their debt burden and improve their profits and livelihood.
