Effect of Growth hormones for direct organogenesis in Bael (Aegle marmelos (L.) corr)
Get PDFAegle marmelos (L.) corr. commonly known as ‘Bael’ tree is included in the red- listed medicinal tree in South India. Riped and unripe fruits, root, bark and leaves of the tree are used in ayurvedic preparation for various ailments. This study was conducted to standardize the media for multiple shoot induction from different explants under in vitro condition. Among the various explants viz., meristematic tip, nodal bud, tender leaf, auxillary bud and cotyledon tried in different media, auxiliary bud had shown good response for shoot induction in 36 to 39 days. Among the various treatments viz., WPM supplemented with Benzyl Amino Purine (BAP) (0.5 to 3.0mg/lit), Kinetin (KN) (0.5 to 3mg/lit) and Indole acetic acid (IAA) (0.5 to 2mg/lit) for multiple shoot induction, the treatmental combination of WPM supplemented with BAP, KN and IAA, @ of each 0.5 mg/lit resulted in 7.75 shoots per cotyledon. The same combination, ½ strength of the medium with 1mg/lit BAP+2mg/lit NAA+ 1% AC resulted in root formation. Hence, as a means of in vitro conservation using cotyledon as explants microproagation is possible in bael
Traditional practices of utilization and conservation of non-wood forest products by Adi tribes of Arunachal Pradesh
Get PDFThe survey was carried out during 2009-11 to collect the information of Non-Wood Forest Products (NWFPs) utilized by the Adi tribes of East Siang District of Arunachal Pradesh. It was observeds that Adi tribes used to collect different NWFPs such as wild fruits (Artocarpus heterophyllum Lam., Castanopsis indica (Roxb. ex Lindl.) A. DC., Canarium strictum Roxb. etc.), vegetables (Bauhinia variegata L., Clerodendrum colebrookianum Walp., Diplazium esculentum (Retz.) Sw., Moringa oleifera Lam. etc.), spices (Cinnamomum tamala Nees & Eber.,Cinnamomum zeylanicum Blume. and Piper longum L.), fibres (Calamus flagellum Griff. ex Mart., Dendrocalamus hemiltonii Nees et Arn. ex Munro, Pandanus nepaulensis H. St. John and Sterculia villosa Roxb.), floss (Bombax ceiba L.,), broom grass (Thysanolaena maxima (Roxb.) Ktze.), thatching material (Livistona jenkinsiana Griff.), various bamboo and cane species, and other miscellaneous products from the forests and community lands. NWFPs played a significant role in supporting the livelihood of Adi tribes as it has been observed that 32.50 %, 56.67 % and 10.83 % people were earning < Rs. 3000, Rs. 3000 - 6000 and > Rs. 6000, respectively from the sale of different NWFPs. Majority of respondents (80.83 %) were having the opinion that the availability of different NWFPs has declined considerably and maximum (85 %) respondents advocated that the availability of these products would further decrease in future also. Further, Adi tribal community is playing an important role in conservation of different NWFPs yielding species by domesticating them in their home gardens
Development and evaluation of nutritionally enhanced potato rice papads (Indian cookie)
Get PDFThe present study was carried out to develop papads (Indian cookie) from potato (Solanum tuberosum L.) and rice (Oryza sativa) blends and to analyze them for organoleptic, physicochemical, phytochemical and shelf life quality. Two processing cultivars (Kufri Chipsona-1, Kufri Chandramukhi) and one commonly grown cultivar (Kufri Pukhraj) were evaluated for processing into papad. Based on preliminary sensory trails, papads with boiled potato mash (60%) and gelatinized rice (30%) level of supplementation were found to be most acceptable and these papads were subjected to nutritional evaluation. Results were compared with rice papads (control). Protein content and yield was significantly (p<0.05) higher in control papads compared to potato supplemented papads. Oil uptake significantly (p<0.05) increased on supplementation with potato. Bioactive compounds including ascorbic acid, totalphenolics and total antioxidant activity measured as DPPH radical scavenging activity increased significantly (p<0.05) on incorporation of potato. Between the cultivars, papads enriched with Kufri Pukhraj, a table variety which is considered unfit for processing, displayed the highest phytochemical content and total antioxidant activity. Sensory evaluation indicated higher overall acceptability scores of potato enriched papads compared to control. During storage of papads at room temperature for up to 3 months, significant (p<0.05) changes in the moisture content, phytochemical content and antioxidant activity were observed. Storage studies showed that the potato supplemented papads can be stored safely for 3 months of storage at ambient temperature
Resource management for apple scab and sanjose scale control of apple in Kashmir Valley of J&K State
Get PDFThe study on resource management for apple scab and sanjose scale of apple in Kashmir Valley of J&K State was conducted purposively in Sopore and Patten tehsils of Baramulla district covering 4 villages with a sample size of 200 apple growers selected through random sampling method. The study revealed that all the apple growers (100%) from rainfed and irrigated areas were applying the resource management practices such as checking the expiry of chemical before purchase, undertake precautions while using chemicals and sprayers, purchaseeconomical and convenient packing’s of plant protection chemicals, check the working condition of the sprayers on regular basis, undertaking care and maintenance of sprayers regularly and were able to repair the minor defects of sprayers by self followed by (66%) apple growers who had decided to planed plant protection schedule in advance. The data further showed that hired labour for disease and pest management of apple were available easily and locally, and as per requirement (100%). As regards prevailing wage rates (88%) farmers from rainfed and (91%) from irrigated area reported that these were reasonable. Plant protection chemicals needed for control of disease and pest of apple were found adopted by cent per cent farmers. The plant protection chemicals were also available in suitable packings (97%) and before the expiry date (96%). The critical evaluation of the plant protection chemicals and equipments before their use with regard to their quality being taken care by all the apple growers would help in eradication of the disease from the region
Biomass production, carbon sequestration and economics of on-farm poplar plantations in Punjab, India
Get PDFSix years poplar plantations were assessed for productivity, carbon storage and economics in comparison to sole cropping. Wheat grain yield was significantly higher in control plots (4.55 t/ha) than boundary plantation (3.28 t/ha) and block plantation (2.03 t/ha). Similar trend was recorded for straw yield (6.61 t/ha in control plots, 4.83 t/ha in boundary plantation and 3.5 t/ha in block plantation. The boundary plantation produced higher DBH (24.23 cm) than the block plantation (19.71 cm). The crown spread itself followed the same trend but both the planting methods had almost similar plant height. However, the total tree biomass was higher with block plantation (96.31 t/ha) than boundary plantation (30.14 t/ha) but per tree biomass was more in boundary plantation than block plantation. The total carbon storage was higher in block planting method (55.43 t/ha) than in boundary plantation (32.70 t/ha) and lowest total carbon storage in sole cropping system (31.20 t/ha). The heat from biomass combustion and carbon storage from coal substituted of timber was also higher in the block plantation (18.67t C/ha) as compared with boundary plantation (4.43t C/ha). Agro forestry systems likely had a greater capacity to sequester C in the longterm than the annual cropping systems because of their diverse configurations. The economic benefits were also higher in block plantation than boundary and sole cropping of rice-wheat (B : C ratio of 3.30, 1.90 and 1.61, respectively). Adoption of on-farm poplar plantations will develop new opportunities for enhanced income in addition to employment and environmental amelioration
Prevalence, serodiversity and antibiogram of enterotoxigenic Escherichia coli (ETEC) in diarrhoeic calves and lambs of Kashmir valley (J&K), India
Get PDFEnterotoxigenic E. coli (ETEC) is the major cause of diarrhoea in neonatal animals. This study determined the prevalence, serological diversity, virulence gene profile and in-vitro antibiogram of ETEC isolates from diarrhoeic faeces of calves and lambs. The prevalence rate of ETEC in lambs was recorded 18.46 % with O8 as predominant serotype. However, in calves the prevalence rate was recorded 8.57 % with O15 and O26 as predominant serotypes. The antibiogram screening showed differential susceptibility pattern among ETEC isolates with highest resistance to ampicillin and highest sensitivity to enrofloxacin. In the present study, for the first time it was reported that the diarrhoea in calves and lambs occur due to virulent gene est not due to elt gene, which was absent in all the isolates
Effect of seed enhancement treatment on field performance of chickpea (Cicer arietinum L.)
Get PDFChickpea (Cicer arietinum L.) is an important winter season pulse crop in India grown in drought prone semi-arid and tropical regions. The aim of present investigation was to find out the effect of seed enhancement treatment on field performance of chickpea. Seeds of Chickpea Desi cultivar Pusa 256, Pusa 2028, and Kabuli cultivar Pusa1053, Pusa1108, each of fresh and 4 yrs old lots were taken for seed enhancement treatments like osmo-priming, halo-priming, fungicidal, botanical and polymer coating alone and in combination with thiram and neem oil. It was observed that seed treatment with thiram alone or in combination with polymer (PVP or PEM) significantly enhances germination and field emergence. Old seed lots of particularly Pusa 256 gives better result. The speed of emergence was invariably high in fresh seed lot (9.43) than old seed lots (4.84). However, in old seed lots, only halo-priming and polymer (PVP) in combination with thiram improved the speed of emergence significantly. Thus seeds treatment with thiram or in combination with hydrophilic polymers could be used for enhancing theperformance of chickpea
