Control of Deacetylation in Gum Karaya on Storage for Quality Retention
Abstract:
Gum karaya is natural exudate from Sterculia urens and it is a partially acetylated polysaccharide which is composed of 10-14 % acetyl groups. On ageing, deacetylation process takes place and with the result that there is continuous loss of acetic acid is formed and the quality of gum karaya deteriorates subsequently. As there is no data available on the effect the quality aspects of gum karaya, therefore a detailed study was undertaken for the control of loss of acetyl groups from gum karaya samples with time and storage conditions using different packaging films. Gum karaya samples packed in Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polypropylene (PP) and Aluminium Coated Polyethylene (ACP) with normal sealing and vacuum packaging with nitrogen filling. Samples were stored under ambient conditions as well as under refrigerated condition. On the basis of quarterly estimation of quality parameters of gum karaya packed in above film it was established that gum karaya samples can be stored for longer period in HDPE under cold condition for controlling the deacetylation process of karaya gum for retention of all quality parameters.

Breeding and Seed Rearing of Climbing Perch (Anabas testudineus, Bloch) Using Farmer Friendly Innovative Technology at Farmer’s Field: A Case Study
Abstract:

Climbing perch (Anabas testudineus), a high valued indigenous fish species both nutritionally and commercially was bred at farmers field during May, 2016 in Nalbari district of Assam. An innovative breeding system was developed and used for induce breeding. It was found that about 490-810 numbers of eggs were laid by the fish per gram body weight basis where fertilization rate was about 92±3%. The mating process was found polygamy. The eggs as well as fertilized eggs were floating in water surface. The fertilized eggs were hatched after 22 hours of fertilization. The three days old spawn were reared in earthen tank where the survival rate after a period of one month culture was observed about 40%. The proficient low cost breeding and seed rearing technique was found farmer friendly as the initial cost was very low and can be carried out in a small area.

Title:
Development of Pre-mature Flowering Resistant Tossa Jute (Corchorus olitorius L.) Varieties for Early Sowing with Specific Reference to Study of DNA Profiles
Abstract:

Considering the importance of availability of tossa jute (C.olitorius) variety for early sowing (1st week of March) and to suitably fit the crop in jute-paddy cropping system as well as intercropping with mung bean, an effort was made to develop premature flowering resistant variety along with higher fibre yield. A total of four new varieties of such kind were developed and evaluated with popular checks (JRO 524 & JRO 204) under six staggered sowing at 12 days interval starting from 20th February in two consecutive years. Out of four new varieties (viz, NJ 7050, NJ 7055, NJ 7010 and NJ 7005), the first two showed very remarkable level of resistance to pre-mature flowering along with higher fibre yield under very early (20th of February) and early (4th March) sowing. The other two varieties e.g., NJ 7010 (Rani) and NJ 7005 (Raja) had also recorded acceptable level of resistance to pre-mature flowering and higher fibre yield under both early (4th March) and timely (16th March to 9th April) sowing schedule. In addition,the 4th jute variety NJ 7005 (Raja) had also nicely demonstrated its suitability under late sowing schedule too (21st April). In the present paper details of the materials under study along with pedigree, DNA profile and field data have been presented and inferences drawn.

Title:
Thermal Behaviour of Buchanania lanzan Gums Collected from Different Places
Abstract:

Buchanania lanzan Spreng., a natural plant polysaccharide, commonly known as char, achar, piyar, chirongi and pre-dominantly the trees are available in the States of Chhattisgarh, Jharkhand, Madhya Pradesh and in Varanasi and Mirzapur districts of Uttar Pradesh. During last two decades plant polysaccharides/natural polymeric materials have evoked tremendous interest due to their diverse pharmaceutical applications such as diluents, binders, disintegrants, bio-adhesives, thickeners, emulsifiers, stabilizers, gelling agents as also in cosmetics, textiles, paints and paper-making etc. Many natural polysaccharides have been successfully used in sustained drug release because of their well-known non-toxicity, biodegradability, biocompatibility, biosafety, sustainability and unique physico-chemical properties, often at very low costs, as compared to their synthetic counterparts. Further, water-soluble polysaccharides certainly have enormously large and broad applications in both food and non-food industries. The present paper reports the thermal behaviour of Buchanania lanzan gum exudates, collected from different places, using various parameters i.e. Differential Scanning Calorimetry (DSC), Differential Thermal Analysis (DTA), Thermo-gravimetric Analysis (TGA), Fourier Transform-Infra Red (FTIR) and Particle Size Analysis, as thermal analysis gives information about changes in material properties as function of temperature. The TG thermograms for all the gum samples showed three-stage decomposition. The DSC thermograms of gums showed glass transitions ranging from 80.93 to 91.96 oC. The FTIR spectrum of Buchanania lanzan gum exudates, collected from different places exhibited the typical bands and peak characteristic for the gums. The particle size analysis of gum samples exhibited d50 values ranging from 56.50 to 254.2 μm.

Title:
Farm Women in Indian Agriculture: Facts and Interpretations
Abstract:

Women are the backbone of the development of rural and national economics. They compromise 43% of world’s agricultural labour force, which rises to 70% in some countries. In the Indian subcontinent the agriculture sector workforce was reported to be 75% in 2011. In rural India the percentage of women who depend in agriculture for their livelihood is as high as 84%; women make up about 33% of cultivators and 47% of agricultural labourers. In as many as 23 of 29 Indian states, women’s share in total workforce in agriculture, forestry and fisheries is over 50%. They spend about 30 hours in a week doing agricultural works. The traditional agricultural methods heavily utilized by women subsistence farmers boast environment friendly features such as seed preservation, natural fertilizers and crop rotation techniques that do not exhaust delicate soil. Sadly women are grossly discriminated in several respects. In all activities there is gender wage disparity, with women earning only 60 to 70% of men’s wage. Many women in India participate in agricultural work as unpaid subsistence labour. Gender disparity in farm work varies from state to state and is relatively less in the hilly areas where agriculture depends heavily on females. Gender work participation disparity with index values ranges from 0.34 to .059. General trend records the lack of property ownership and farm land the resources for keeping up their labour stability and stability of their households. The existing grave situation is farther assuming complex dimension with the growing feminization of Indian farming due to increasing migration of rural men for better employability and remuneration. Empowerment of women without gender disparity to safe guard food security is great concern for national economy.
