Present study was undertaken to evaluate the ameliorative effect of α-tocopherol(100 mg/kg) against cartap (16.25 mg/kg and 32.5 mg/kg) induced toxicity following 28days oral exposure in adult male Wistar rats. Cartap exposure did not produce any clinicalsigns of toxicity in rats at both the doses. Weekly Average body weight gain wassignificantly reduced following cartap (32.5 mg/kg). Both absolute and relative organweights did not differ significantly between different treatment groups. Hematologicalparameters did not differ significantly in any of the treatment groups. Plasma Glucose,Total Cholesterol, Triglycerides, AST, ALT, BUN levels were found to be markedlyincreased in cartap alone treatment groups. Plasma calcium levels showed irregular butnon-significant change in response to cartap doses. α-tocopherol co-treatment with cartapproduced non-significant decrease in the plasma levels of Glucose, AST and ALT but thelevels of Total Cholesterol Triglycerides and Calcium were found to be significantlydecreased in both the co-treated groups. BUN levels remained unaffected following α-tocopherol co-treatment.

9.1 Introduction

Depleting natural resources, regulations on synthetic material, growing environmental awareness and economic considerations today happens to be major driving force for utilization of wastes from the agricultural crops and their residues throughout world [1]. These challenges have led to the introduction of sustainable waste management practices via optimization of processing technologies for minimization and creative conversion of the plant and the processing industries biowastes the world over [2,3,4,5]. Although world prices for sugar and petroleum products have shown spectacular variations during the last few decades, the long term outlook is very likely to be a continuous increase in the price of all fossil fuels and stagnation, at best, for the price of sugar [6]. This gloomy prospect led to the renewed interest in the wastes of the sugarcane industry during the last 50 years and has proved that the optimal use of wastes can provide not only a non-negligible support to the sugarcane industry but will also be able to redress the difficult situation sugar is presently experiencing [7]. Reliable statistics are not available to show the detailed end uses of these wastes on a world basis, but from a very rough picture of their trade, we can say that the wastes from the sugar and jaggery industry serve to be amongst the richest bioresource in this era of recycling of biowastes for renewable wealth generation [8].

Pure sugar when heated melts at about 160-1800c. at about 2100c sucrose loses water and becomes caramel.

CARBOHYDRATES AND SUGARS

Carbohydrates which include sugars and starches are among the most important of the food stuffs as well as the simplest of organic foods. They may be divided into three groups.

Group – I

Monosaccharides  : These are simple sugars that cannot be split into any simpler forms. The principal ones are glucose or dextrose, fructose and galactose. Glucose sometimes known as dextrose or grape sugar is found widely distributed in nature, especially in fruits and vegetables, and is one of the main constuents of honey.

It is in the form of glucose that sugar appears in the blood and is being burned continuously to produce energy. A certain amount of surplus glucose is absorbed from the digestive tract and stored in the liver as glycogen, which can be converted back into glucose when the need for more fuel arises. In the presence of yeasts, glucose undergoes fermentation and changes into alcohol.

Sugarcane (Saccharum officinarum)

Sugarcane is an important agro-industrial crop of tropical and subtropical region of the world. Sugar industry is next to textile industry provide employment to large number of people. It is the main crop of earning foreign exchange. It shares about 2% GDP.

Family : Gramineae (Poaceae)

Importance (Second largest agro-based industry)

• It is cash crop used for sugar, Jaggery (Gur) and Khandsari.
• Green top is used as green fodder. Dry leaves used as mulching and as a fuel.
• Bagasse (By product) is used as fuel, for the production of fibre board, paper etc. and for power generation (electricity).
• Molasses is used in distilleries for the manufacture of alcohol and is also used as an additive to feed livestock.
• Press mud is used as soil amendments, organic manure

Indian canes probably originated in the moist parts of North Eastern India from some plants closely related to Saccharum spontaneum (Barber, 1931). Brandes (1956) concluded that tropical cane might have originated in some of the larger islands of Oceania countries most probably in New Guinea, where various forms of thick, tall tropical canes have been grown from ancient times. Parthasarathy (1946) believed that India is the original home of Saccharum officinarum.

Introduction
 
Sugarcane is an important cash crop of India. Since 1930-31 the area of sugarcane in the country has increased by about 4.3 times and production by about 9.8 times because of the rise in productivity of sugarcane by about 2.28 times, however, during the last decade there is no perceptible increase in productivity of sugarcane in the country. The domestic demand of sugar is around 22-23 million tonnes annually whereas the production of sugar in India is about 26 million tonnes annually. Data on nitrogen use efficiency of sugarcane from 1998-99 to 2013-14 in India is depicted in Fig. 1 and 2 show a decreasing trend (Anonymous, 2015). However, the escalating price of fertilizers in the market has become a cause of concern to sustain the productivity of the crop.

Red Rot
Diagnostic Symptoms
• Practically all above ground parts are affected, but stalks are the main targets of stack.
• Spindle leaves (third or fourth)starts drying.
• Further stalks becomes discolored and hollow.
• Diagnostic symptom is th formation of red streaks, interrupted by white patches , inside the stalk.This can be seen by splitting the stalks longitudinally.
• White patches are characteristics of disease, not found in other stalk rots.
• After splitting opened the diseased stalk, a sour smell due to conversion of glucose to alcohol.
• Red longitudinal lesions are also seen on the mid ribs of the leaves on which black color fruiting body (Acervuli) are formed (Fig.1).

Introduction
Sugarcane (Saccharum officinarum Linn.) is a remarkable tall, perennial grass characterized by its thick, jointed stalks and long linear leaves. This remarkable plant, known for its ability to efficiently photosynthesize in warm climates, is a C4 plant. The propagation of sugarcane primarily occurs through stem cuttings, as it seldom produces flowers and seeds. It finds roots in regions with tropical and subtropical climates featuring warm temperatures, abundant sunshine, and well-drained fertile soil (Shukla et al., 2017). Cultivated for its sweet juice, rich in sucrose, sugarcane serves as the primary raw material for the production of sugar, ethanol, and various other valuable products. Its lifecycle comprises several growth stages, including germination, tillering, grand growth, and maturation, culminating in the harvesting of its valuable juice. Continuous advancements in botany and genetics have contributed to the improvement of sugarcane cultivation, enhancing yield and resistance to pests and diseases. The origins and domestication of sugarcane can be traced back to Southeast Asia, particularly in regions encompassing Papua New Guinea, Indonesia, and their vicinity. The domestication of sugarcane is believed to have commenced thousands of years ago when early human populations in these regions recognized the sweetness of the cane and began cultivating it for its edible properties. Over time, through selective breeding and propagation of plants with desirable traits, these early cultivators played a pivotal role in shaping the sugarcane we know today. This indigenous Southeast Asian plant spread to other parts of the world through trade and exploration. Historical records indicate that sugarcane found its way to India around 500 BC and reached China in the 6th century AD. Subsequently, it traversed the Middle East, the Mediterranean region, and eventually reached the Americas during the early voyages of exploration and colonization (Grivet et al., 2004). Christopher Columbus played a significant role in introducing sugarcane to the Caribbean islands during his second voyage in 1493, and from there, it made its way to other parts of the New World, including Brazil and various South American countries. The cultivation of sugarcane emerged as an essential industry in these regions, profoundly influencing their economic and social landscapes. The domestication and widespread cultivation of sugarcane have left an indelible mark on the global economy, trade, and human history. Today, sugarcane remains one of the most significant crops globally, with major producing countries, including Brazil, India, China, Thailand, and others. It stands not only as a pivotal

The disease was fi rst reported in Java in 1893 and is prevalent in all sugarcane growing countries. In India the disease occurs in an epiphytotic form in Uttar Pradesh and Bihar during 1939-1940 and 1946-1947 and cause severe damage that threatened the existence of sugar industries.

In fruits, vegetables, and their products, the sugars are estimated as reducing sugars, non-reducing sugars, and total sugars. Reducing sugars in fruits and their products represent glucose and fructose. A combination of reducing and non-reducing sugars gives total sugars, whereas non-reducing sugars mainly sucrose are calculated after deducting the value of reducing sugars from the total sugars as invert sugar and multiplying the remainder with a factor of 0.95. Many fruit, vegetables, and their products like jam, jelly, juice, preserve, candy, fruit toffees, etc., containing substantial amounts of sugars, are estimated as a routine by using Lane and Eynon’s method using Fehling’s solution. However, for products having a smaller quantity of sugars, more precise methods like colorimetric methods can be used.
Method: Lane and Eynon’s Method
Principle: Invert sugar reduces the copper in Fehling’s solution to red, insoluble cuprous oxide. The sugar content in a food sample is estimated by determining the volume of the unknown sugar solution required to completely reduce a known volume of Fehling’s solution. Glucose, fructose and other] sugars capable of reducing oxidizing agents are called reducing sugars and this property is used for the estimation of sugars.

If you have prepared yourself to make research as your career, it is most advantageous to read research papers/reviews/chapters/books published by the eminent scientists. It is not necessary to confine reading to your subject but a voracious reading will enable you to develop an idea about general problems related to science and our society; how scientists managed to solve them and with development of new knowledge, how you may tackle fresh or existing problems. A deep analysis may be done of those works which are so accurate that even after lapse of so many years, they still hold true. In our opinion, it is better to launch websites/blogs highlighting important works of eminent Parasitologists for the benefit of our research scholars; a beginning, in India in Parasitology, has been made in this direction with launch of a website on first time Rafi Ahmed Kidwai award winner (in Animal Sciences) late Dr SC Dutt (www.drscdutt.com). 

ABSTRACT

The paper presents the results of agroforestry trials that had been conducted in lower shivaliks for assessing soil and water conservation under different land uses. The experiments reveal that agroforestry is a profitable venture compared to monocroping in lower shivaliks, where agriculture is rainfed.

Introduction

The lower Shivalik is composed of an alternating sequence of well indurated, fine grained, purple and grayish-purple sandstones and purple and maroon clays in the lower part and grayish-purple, medium to fine grained standstones in the upper part. The formation attains a thickness of 1,300 m to 1,900 m in the Western Himalaya. The important places of lower Shivaliks are along Sambha-Udhampur Road, Jammu – Srinagar national highway, Nahan, Kalka, Nalagarh, Bilaspur, Sarkaghat regions of Himachal Pradesh. In Kumaon Himalaya, lower Shivaliks are in Kotdwar, Rathwadhab, Mohand, Haldwani and Tanakpur regions

Sulfate can have harmful effects on aquatic life in freshwaters, sulfate cause osmotic stress or specific ion toxicity in aquatic organisms, especially in soft waters where Ca2+ and Mg2+ concentrations are low. Egg fertilization and early embryonic development were the most sensitive developmental stages of whitefish to sulfate (Karjalainen et al., 2021).
Sulphate (SO4 2-) may be estimated by either turbidimetric or gravimetric methods (APHA, 1995)
1. Turbidimetric method is more applicable in the range of 1- 40 mg Sulphate (SO4 2-)/ L
2. Gravimetric method is suitable if the concentration of Sulphate (SO4 2-) is above 10 mg/ L
Turbidimetric Method (Range 1 - 40 mg/L of sulphate) Principle
Sulphate ion (SO4 2-) precipitated with barium chloride (BaCl2) in an acetic acid medium in order to form crystals of barium sulphate (BaSO4).
BaCl2 + SO4 2-+ BaSO4 (precipitate)
The formation of these crystals is increased in the presence of an acetic acid solution containing sodium acetate, potassium nitrate, acetic acid and magnesium chloride. The suspended barium sulphate (BaSO4) is measured by spectrophotometer and concentration of sulphate (SO4 2-) is determined by comparison of the reading with a standard curve. Minimum detectable concentration is approximately 1 mg (SO4 2-) / L.

Microbial transformations of sulfur (S) are even more complex than those of nitrogen because of the large number of oxidation states of S and the fact that several transformations of S also occur abiotically. Although a number of oxidation states of S are possible, only three are significant in nature, 2 (sulfhydryl, R–SH, and sulfide, HS-), 0 (elemental sulfur, S0), and 6 (sulfate, SO₄ 2-). The bulk of S Earth’s S is in sediments and rocks in the form of sulfate minerals, primarily gypsum (CaSO₄) and sulfide minerals (pyrite, FeS2), but the oceans constitute the most significant reservoir of SO₄ ^2- in the biosphere. A significant amount of S, in particular sulfur dioxide (SO₂), enters the S cycle from human activities, primarily the burning of fossil fuels.

Hydrogen Sulfide and Sulfate Reduction

A major volatile S gas is hydrogen sulfide (H₂S). Hydrogen sulfide is produced from bacterial sulfate reduction or is emitted from sulfide springs and volcanoes. Although H₂S is volatile, different forms exist depending on pH: H₂S predominates below pH 7 and the nonvolatile HS- and S^2- predominate above pH 7. Collectively,H₂S, HS, and S₂ are referred to as “sulfide.” Sulfate-reducing bacteria are a large and highly diverse group and are widespread in nature. However, in anoxic habitats such as freshwater sediments and many soils, sulfate reduction is SO₄ ^2- limited. Moreover, because organic electron donors (or H₂, which is a product of the fermentation of organic compounds) are needed to support sulfate reduction, it only occurs where significant amounts of organic material are present.

Sulphur dioxide is used as a preservative in many fruit and vegetable products. It can be added either in the form of potassium metabisulphite or by exposingthe product to sulphur fumigation by burning sulphur powder. Food safety and standards regulations have specified the maximum limit of sulphur dioxide in the finished products. Products having sulphur dioxide content exceeding the limit are considered not conforming to Indian Food Laws. Therefore, the estimation of sulphur dioxide in food products is considered an important attribute for quality evaluation.
Principle
Sulphur dioxide added to the food products may exist as undissociated sulphurous acid, as free bisulphite ions, as free sulphite ions and/or as combined SO2 in the form of hydroxy sulphonates. Sulphur dioxide is measured as free or total SO2.
Free SO2 is measured by direct titration with iodine. In the estimation of total SO2, the combined SO2 is liberated by treatment with excess alkali at room temperature, followed by subsequent acidification to prevent recombination and titration with iodine. The method used is known as the Modified Ripper Titration Method.
