Carotenoids are the most common pigments in nature possessing high nutraceutical value. The objective of the present work was to obtain a good yield of carotenoids from pumpkin tissues, using cellulase and pectinase enzymes. Various parameters such as concentration of enzymes and time of incubation were optimised, to improve the yield of carotenoid from pumpkins. Enzyme-aided extraction of carotenoid from whole pumpkins under optimised conditions resulted in an increase in the carotenoid yield by 33.3% (w/w) in cellulase-treated sample and 28.6% (w/w) in case of pectinase-treated sample. Extraction from pumpkin peel under optimised conditions showed a remarkable increase in the yield of carotenoid by 77.7% (w/w) and 71.4% (w/w), for cellulase- and pectinase-treated samples, respectively. © 2015 Indian Institute of Chemical Engineers.

A field survey was conducted in the year, 2011 - 12 in Imphal valley of Manipur, on the use of herbs as ingredient sources for the preparation of traditional natural herbal shampoo referred to as 'Chinghi', by Meitei community. Methodological field survey and personal interview of local people aged between 30-70 years of both sexes using standard questionnaires were carried out to collect information on the plants use in the herbal shampoo preparation. The survey revealed the therapeutic application of 35 plant species representing 28 genera and 18 families available in the Imphal valley. Tree species contributed immensely, yielding 38%, while herbs 32%, shrubs 27%, and climbing shrubs 3%, respectively being the record of the total number of plants used as ingredient in herbal shampoo preparation. These natural shampoos are used for a wide range of common hair care like anti-ageing of the hair, blackness, shininess and smoothness of the hair. It is prepared from young leaves and tender stalk of shoot of trees or shrubs, or whole plant of the herbs and fresh fruits boiled with local sticky rice water locally called 'Chinghi'. Fermented lime peel is also used as a herbal shampoo. The study shows details of their scientific, common, and local names, including their family, parts used, habit of the plants, and the benefit to the hair health as a whole. Source

The present study was conducted to evaluate the vase life of sweet sultan (Centaurea moschata L.) in different vase solutions with view to use it as cut flower. Various vase solutions such as sucrose @ 2% and in combination with 8-hydroxyquinoline citrate (8-HQC) @ 200ppm, ethanol @ 2% and plant bio-regulators like aminooxy acetic acid (AOA) @ 0.5 mM, salicylic acid (SA) 150 ppm and benzyl adenine (BA) 50 mg/l, ascorbic acid (200 ppm) were used. Vase life of flowers was found as 4.67 days in control and 6.0 days in treatment with sucrose (2%) alone. However, the vase life was significantly increased in treatments with plant bio regulators namely ascorbic acid, salicylic acid, benzyl adenine and AOA (9.67, 9.33 days and 9 days/respectively). Treatments with 8 HQC and ethanol along with sugar also increased the vase life of the flowers significantly than control. Maximum increase in flower weight (7.80 g) was observed in treatment with AOA on 8th day whereas, maximum flower diameter (71.80 mm) was observed in treatment with BA on 10th day. The maximum membrane stability index (57.50%) and total chlorophyll content of bract (1.22 mg/g) were recorded in treatment with ascorbic acid after 9 days of vase life. Source

A farmers' participatory field experiment with four different rice-based cropping systems was conducted during 2011-12 and 2012-13 in coastal saline zone of West Bengal. Due to low land agro-ecosystem, conventionally farmers grow long duration high yielding varieties of rice during wet season and keep their land either fallow or marginally growing some low water requiring crops in dry season (rabi and summer) using residual moisture or life saving irrigation. This study was aimed to evaluated profitability and resource use efficiency of rice-greengram, rice - sunflower, rice - sunflower + greengram and rice - lady's finger cropping systems. Rice - lady's finger cropping system recorded significantly higher yield of rice grain (4,617.04 kg ha-1) and straw (6,605.11 kg ha-1), system equivalent yield (28,080.17 kg ha-1) and productivity (78.01 kg ha-1 day-1). The highest net return (Rs. 1,44,600 ha-1) and B:C ratio (2:24) were also obtained in rice - lady's finger cropping system, followed by rice - sunflower. Rice - sunflower cropping system recorded significantly higher phosphate and potash uptake, however, regarding nitrogen uptake the same was at par with rice - lady's finger system. Higher land use efficiency, irrigation water use efficiency, energy output and employment generation were registered with rice - lady's finger system followed by rice - sunflower. Source

A field experiment was undertaken at Indian Agricultural Research Institute, New Delhi during kharif (rainy season) in the year 2010 to evaluate the residue persistence of flubendiamide in/on okra fruits following foliar application of Belt 39.35% SC formulation at 24 (standard dose) and 48 (double dose) g a.i. ha -1. After HPLC analysis study revealed that residues of flubendiamide in/on okra persisted till 5th and 7th day after the last spray at standard and double dose, respectively. The residues of flubendiamide were reported as parent compound, and des-iodo flubendiamide, a metabolite (photo product) of flubendiamide, was not detected in/on okra at any time during the study period. The initial deposits of 0.28 and 0.53 μg g -1 in/on okra fruits reached below determination level of 0.01 μg g -1 on the 7th and 10th day at standard and double dose, respectively. The half life of flubendiamide in/on okra fruits ranged from 4.7 to 5.1 days at standard and double dose, respectively. Soil sample collected from the treated field on the 15th day after the last spray revealed residues of flubendiamide or its metabolite below determination level (0.01 μg g -1) at single and double dose. © 2011 Springer Science+Business Media, LLC.
