Antioxidant Activities of Molokhia (Corchorus olitorius L.) Extracts

Abstract: Corchorus olitorius L. (Molokhia) (Tiliaceae), collected from the Doganci, Guzelyurt, Northern Cyprus, infusion and extracts with different polarities have been studied for their polyphenolic contents and antioxidant activities. Total phenolic content was determined spectrometrically according to the Folin-Ciocalteu method and calculated as gallic acid equivalents (GAE). Antioxidant activitiy was studied in an aqueous emulsion system of β-carotene and linoleic acid by measuring the absorbance of the samples. The free radical-scavenging properties were also evaluated against 2,2-diphenyl-1-picryhydrazyl radical (DPPH•). Results were compared those of an synthetic antioxidant, BHT. Antioxidant effects were correlated with the total amount of phenolic compounds contained in the extracts. In all these cases higher antioxidant activity was seen in the samples with higher phenolic content.

Impact of frontline demonstrations on jute (Corchorus olitorius)

Abstract: In order to increase production and productivity of jute (Corchorus olitorius) by adopting improved production technologies, several frontline demonstrations (FLDs) on jute with package technologies were conducted by Central Research Institute for Jute and Allied Fibres (CRIJAF), Barrackpore during 1996 to 2005 i n eight different villages of North 24-Parganas and Hooghly districts of West Bengal. A study on impact of the demonstrations on the farmers' behaviour was conducted. Results of the study revealed that demonstrated technologies increased the fibre yield of jute by 4.45 q ha-1 over the farmer's practice (25.10 q ha -1), the post-demonstration yield was 29.55 q ha -1 as the farmers adopted many components of the technology package that were used in demonstrations. Economic surplus from increased production of jute fibre by about 4.45 q ha -1 provided additional Rs. 5570 ha-1 to the farmers. The results further indicated that additional income that accrued due to increased harvest of jute by adopting improved practices was utilized by the farmers by increasing expenditure by about 50%, on food, health care of the family members, education of children, and purcha se of farm implements or essential items and attending social and entertainment programmes. Impact of the demonstrated technologies to increase fibre yield of jute by contact farmers up to 3 q ha -1 in nearby villages within radius of three to seven km distance from the adopted villages was also found. A definite impact of the FLDs was thus observed.

Effect of integrated nutrient management on productivity of tossa jute (Corchorus olitorius L.) and on soil properties.

Abstract: A field experiment was conducted at the Regional Agricultural Research Station, AAU, Nagaon, Assam during 2005 and 2006 under rainfed conditions to study the effect of combined application of chemical fertilizers, bio-fertilizer and FYM on soil nutrient status, fibre yield and mineral nutrition of tossa jute. Application of 50% reduced dose of N and P fertilizer along with inoculation of seed with bio-fertilizer (Azotobacter and PSB) produced similar fibre yield and gave higher net return, B:C ratio and also improved soil nutrient status as compared to application of 100% recommended NPK fertilizer. Similarly, addition of FYM @ 3t/ha along with 50% recommended NP fertilizer and bio-fertilizer had further increased the fibre yield, income and soil nutrient status as compared to application of 100% recommended NPK fertilizer along with FYM

Effect of moisture regimes and level of fertilizer application on yield and water requirement of jute (Corchorus olitorius L. and Corchorus capsularis L.)

Abstract: SUMMARY Field experiments on the effect of moisture regimes and fertilizer application on fibre yield of two jute varieties showed that JRO 632 (Corchorus olitorius L.) produced significantly more fibre, utilized moisture more efficiently and extracted water from deeper layers than did JRC 212 (Corchorus capsularis L.). Scheduling of irrigation at 20% available soil moisture (ASM) gave the highest fibre yield in normal (1970) and drought (1972) years but unirrigated conditions (dry regime) gave highest yield in a year of excess rainfall (1971). The consumptive use (CU) increased from dry to wet regimes and the water use efficiency (WTJE) was greater in dry regimes in normal as well as in excess rainfall years. But the WUE was maximal when the crop was irrigated at 60% ASM in the drought year. The water requirement of the jute crop was 490 mm in the normal and excess rainfall years (20% ASM and dry regime respectively) while in the drought year it was 560 mm (20% ASM). The moisture extraction was more from deeper depths in the dry regime and only from shallower depths in wet regimes. The fibre yield increased with increase in nitrogen application from 40 to 80 kg/ha. Application of 40 kg P2O5 and 40 kg K2O/ha did not improve the fibre yield in the excess rainfall and drought years. In the drought year (1972) irrigating at 20% ASM and 80 kg N/ha and in the excess rainfall year (1971) the dry regime with 40 kg N/ha produced highest fibre yields. There was not much variation in CU and WE of the crop due to different fertilizer levels. The WUE was increased by irrigating at 20% ASM with 80 kg N/ha in a crop rotation system where P and K were applied to preceding crop.
