Abstract

Nagarmotha (Cyperus scariosus R. Br.) is the most important locally available minor forest produce resource of Chhattisgarh and a significant contributor in the revenue of Minor Forest Produce Co-operative Federation Limited., Chhattisgarh. Due to its unsustainable over exploitation it is under threat of depletion. Keeping this in view the present investigation was conducted at Kajool nadi and Bhabaarganj nadi, Dhugli Range, Dhamtari District, Chhattisgarh to know the effect of harvesting intensity on regeneration/ multiplication status of this species. The study area consists of four plots each randomly allotted to four different harvesting intensities (treatments) viz. 60%, 70%, 80% and 90% harvest. In each plot total growing plant population were counted, thereafter as per the allotment 60%, 70%, 80% and 90% plants were upischolar_mained from the whole plot. From the harvested tillers rhizomes were removed, cut into small pieces and essential oil was extracted by steam distillation and yield of the oil was quantified (0.04−0.07%). The whole experiment was reassessed in the month of December 2006 and total Nagarmotha plants in each plot were again counted and the data so obtained was then subjected to analysis of variance. Conclusively from the experiment it was inferred that for the sustainable harvesting 80% to 90% population of Nagarmotha should only be harvested uniformly from the whole plot to ensure proper regeneration.

Abstract

Starch is the principal carbohydrate photosynthesized by means of solar energy. It is produced by all green plants and is basically found in the seeds, fruits, tubers, ischolar_mains and stems of various plants, notably in corn, potatoes, wheat and rice. Starch varies widely according to its source owing to its granular characteristics. Curcuma angustifolia Roxb. (Tikhur) and Curculigo orchioides Gaertn. (Kalimusli), two important medicinal plants, contains starch in its rhizome and ischolar_main stock. Starch from these species was isolated, purified and yield of starch was found 37.64 % in C. angustifolia and 11.56 % in C. orchioides. The X-ray diffraction pattern of C. angustifolia starch, exhibited 6 peaks at reflection angle 14.2° , 17.2° , 19.4° , 22.15° , 24.2° and 26.2° . Of these 6 peaks, one peak at reflection angle 17.2 was strong, 4 peaks at reflection angle 14.2° , 17.2° , 19.4° , 22.15° , 24.2° were medium and one peak at reflection angle 26.2° was weak. In C. orchioides,9 peaks at reflection angle 11.5° , 14.8° , 15.2° , 16.8° , 18.1° , 23.4° , 24.3° , 26.7° and 27.9° were obtained. Of these 9 peaks, 4 peaks at reflection angle 14.8° , 15.2° , 16.8° , 18.1° , 24.3° were strong, 1 peak at reflection angle 23.4° was medium and 3 peaks at reflection angle 26.7° , 27.9° and 11.5° were weak. The starch pattern in C. angustifolia resembles with the 'B' pattern of potato starch and that of C. orchioides resembles with the 'A' pattern of corn starch. From the results, it can be concluded that Curcuma angustifolia and Curculigo orchioides starches could become alternatives for food developers.

Abstract

Curcuma angustifolia Roxb. starch was isolated from the rhizomes and got purified. In C. angustifolia starch absolute density 1.45, fat/lipid content 1.23%, total ash 1.28%, acid insoluble ash 0.31%, sulphated ash 0.99%, water binding capacity 89.89%, gelatinization temperature ranged 75°C to 85°C and Barbender viscosity 4968 cps were recorded. The solubility of starch ranging from 1.28 to 46.68 and swelling power 2.58 to 49.05 from serially heating at 50°C to 95°C were obtained. The granule shape was rounded, oval to elliptical spherical and elongated from 3.32μto 32.55μ in length and 2.29μ to 23.76μ in width.

Abstract

The findings of study reveal that most of the respondents in the age group of 15- 20 years. Majority of respondents belonged to other back ward class, married, nuclear family system and low income group. More than one-third (32.66%) of respondents were functionally educated upto primary level. A maximum of 85.33 per cent respondents were from farmers having thatched house. Most of the respondents were from one hectare land and having Harrow. A majority of the respondents had cycle and mobile for their work. Nearly three-fourth (73.33%) of the respondents belonged to low social participation.
