Effect of pre harvest application of boron and zinc on post harvest quality and vaselife of carnation
Get PDFThe study was conducted to determine the effect of pre harvest spray of micronutrients like boron, zinc and its combination on post harvest quality and vase life of carnation. Post harvest quality of flowers like flower stalk length (65.61 cm) was maximum in the plant treated with zinc (0.3 per cent), and calyx splitting (3.12 per cent) was minimum in the plants treated with boron (0.1 per cent). Flower diameter (6.64 cm) was highest with boron (0.1 per cent) + zinc (0.3 per cent) treatment. Plants without micronutrient treatment produced poor quality flowers. Regarding vase life studies maximum water uptake and minimum transpiration loss from first day to sixteenth day was resulted in the flowers which are obtained from the plant treated with boron (0.1 per cent). The maximum fresh weight of the flower was noticed in combination of boron (0.1 per cent) + zinc (0.3 per cent) from first to sixteenth day. The foliar spray of boron (0.1 per cent) recorded maximum vase life (11.05 days). So the good quality of flowers can be improved by the foliar spray of zinc, calyx splitting can be controlled by boron foliar spray and vase life of the flower can be maintained by foliar spray of boron. It is confirmed that the foliar application of micronutrient is very much helpful for the improvement of post harvest quality and vase life of carnation
Effect of nutrients sprays on growth, yield and fruit quality of apple under cold desert condition of Himachal Pradesh
Get PDFThe on farm trial was carried out to study the effect of nutrients sprays on growth, yield and fruit quality of apple cv. Royal Delicious under cold desert condition of Himachal Pradesh. Treatments comprised spray of boric acid (0.1%), urea (0.5%), boric acid (0.1%) + urea (0.5%), multiplex (250 ml/100 litre of water) and no use of nutrients (water spray). The highest growth in terms of shoot length was observed with spray of urea at 0.5% and the highest fruit set and yield were recorded with boric acid (0.1%) + urea (0.5%) followed by boric acid at 0.1%. The lowest growth, fruit set and yield were observed with control. The combination of boric acid (0.1%) + urea (0.5%) resulted in the highest fruit length, breadth and weight. The highest total soluble solids were recorded with boric acid 0.1% and the reducing and total sugars were the highest with control. The acidity was found maximum while total soluble solids, reducing and total sugars were recorded lowest with spray of urea 0.5%. The treatment comprising of boric acid (0.1%) + urea (0.5%) proved to be best in terms of fruit set, yield and quality parameters of apple followed by boric acid at 0.1% concentration
Agro-morphological and quality characterization of indigenous and exotic aromatic rice (Oryza sativa L.) germplasm
Get PDFFor establishment of the distinctness among 64 aromatic rice germplasm, 35 agro-morphological and quality traits were used. Most of the studied traits showed wide variation among the germplasm. Purple colour of auricles and ligule was found in only one genotype, while light purple colour of auricles was recorded in four genotypes. White colour of stigma was recorded in 57 accessions, whereas purple stigma was observed in six accessions. Awns present in 31 accessions. The weight of 1000 grains, which is one of the most important yield attributing traits showed wide variation among accessions, and ranges from very low to very high weight. Grain: length and decorticated grain: length showed high variation and ranges from very short to long type, while grain: width and decorticated grain: width showed somewhat little variation among the genotypes. Extra long slender type grain shape was observed in 27 accessions. White type of decorticated grain colour was found in 55 genotypes, while light red and red colour was observed in only three genotypes. The present study concluded that all sixty four accessions were found to be distinct on the basis of thirty one agro-morphological and quality traits. Accessions having short stem length, very long panicle length, more number of panicle per plant, and extra long slender grain may be used as potential donor in hybridization programmes. This study will be useful for breeders, researchers and farmers toidentify and choose the restoration and conservation of beneficial genes for crop improvement
Role of vitamin C against bifenthrin induced oxidative damage in lungs of Wistar rats
Get PDFThe aim of present study was to unravel the protective role of vitamin C on oxidative stress parameters in lung homogenates of bifenthrin intoxicated rats. Rats were divided into four groups. Group I served as control while group II animals were treated with bifenthrin @ 5.8mg/Kg/day. In group III, vitamin C was orally administered @ 60mg/Kg/day where as group IV received both vitamin C and bifenthrin @ 60mg/Kg/day and 5.8mg/Kg/day respectively. After 30th day of treatment, lung samples were taken and analysed for oxidative stress parameters. Significant (P<0.05) increase in lipid peroxidation was observed from control value of 4.80±0.39 to 7.90±0.50 in bifenthrin treated animals. Mean control values of SOD, GSH-Px and CAT were 0.55±0.05, 0.98±0.03 and 138.70±6.01 which were significantly (P<0.05) decreased to values of 0.27±0.0, 0.53±0.05 and 91.10±9.70 respectively in bifenthrin treated animals. The value of GST increased significantly (p<0.05) to 1.05±0.06 in bifenthrin administered animals from control value of 0.70±0.08. Pre-treatment with vitamin C in ameliorative group IV significantly restored the normal values of lipid peroxidation, SOD, GST and CAT but could not reverse the decreased values of GSH-Px. The present research is first of its type where in free radical generation due to bifenthrin –a commonly used insecticide was evaluated in lung homogenates when given orally which might be due to residues present in the lung. Besides it will be helpful in better understanding of toxicological profile of pyrethoids, the most commonly used insecticides
Productivity, profitability and water use efficiency of wheat (Triticum aestivum L.) under different customized fertilizers and moisture regimes
Get PDFA field experiment was conduct during the winter (rabi) season of 2010-2011 on silty loam soil at Faizabad (Uttar Pradesh), India to develop suitable dose of customized fertilizers (CF) and moisture regime for wheat (Triticum aestivum L.) crop. Productivity of grain and straw of wheat increased with increasing level of nutrient. Highest grain yield (53.13 q ha-1) was recorded under the application of CF 12 : 30 : 16 : 0.5 : 0 : 5 (NPK 150 : 75 : 40) which was accounted increases of 18.22%, 14.55% and 10.88% more yield than F1, F4 and F6 treatment respectively. Highest water use efficiency was recorded with 6 cm irrigation at 0.8 IW/CPE ratio and customize fertilizer 12: 30: 16: 0.5: 0: 5(NPK 150: 75: 40). The highest net returns (Rs. 61324 ha-1) and B:C (2.29) were recorded under the treatment combination of 1.0 IW/CPE ratio + customize fertilizer 12: 30: 16: 0.5: 0: 5 (NPK 150: 75: 40). The increased dose of fertilization in the form of CF with proper irrigation scheduling in wheat has a high scope for the maximization of yield as well as profitability in wheat growing regions of Uttar Pradesh

Get PDFThe field experiment was carried to evaluate the response to the foliar application of micronutrients viz. zinc, iron and boron in single or in different combinations on guava (Psidium guajava L.) cv. Sardar L-49 for various growth, yield and sensory parameters. From various combinations of micronutrients growth characters were remain uninfluenced. Combination of 0.5% Zinc sulphate + 0.5% Ferrus sulphate + 0.3% Borax significantly influenced fruit per shoot (3.6), overall yield (57.1 kg/tree) and sensory characters like aroma (7.7), taste (8.1), flavour (8.2), texture (7.5) and also overall acceptability (7.9). Application of 0.3% Borax significantly influenced flowers per shoot (5.3). Minimum fruit drop was recorded with application of 0.5% Ferrus sulphate + 0.3% Borax and minimum fruit drop per shoot observed in 0.5% Zinc sulphate + 0.3% Borax foliar application. The present study indicated that combined application of micronutrients enhanced fruit set, minimized fruit drop and overall yield. This has resulted in improved sensory characters in the guava fruit. This will lure consumers with appealing fruit that would enable farmers to earn a decent sum of money
Germination and emergence of four rattan Calamus species of Western ghats in response to different pre-sowing seed treatments
Get PDFThe present investigation was carried out to study the effect of ten pre-sowing treatments on germination parameter of the four Calamus species in the nursery of College of Forestry, Vellanikkara. Most of the pre-sowing treatments of Calamus spp. gave better performance compared to the control. Complete removal of outer pericarp and sarcotesta of each seed manually (T2), Sulphuric acid treatment for 3-5 minutes after removing sarcotesta (T6) and Hot water treatment (500C) after removing sarcotesta for two minutes followed by soaking in water for 12 hours (T7) were found promising in all the species. The higher germination percentage (83.82, 89.96), mean daily germination (0.020, 3.39), peak value of germination (0.026, 3.45) and germination value (0.00041, 11.56) and was recorded for Calamus thwaitesii and C. metzianus in treatment with GA3 (T9) respectively. The maximum germination percentage (27.74), MDG (0.41), PVG (0.46) and GV (0.20) for C. hookerianus in T7 (Hot water treatment (500C) after removing sarcotesta for two minutes followed by soaking in water for 12 hours), and highest MDG (0.078), PVG (0.91) and GV (0.0065) for C. travancoricus in T5 (Sulphuric acid treatment for 3-5 minutes without removing sarcotesta). The present study reiterated that the pre-sowing treatments hold major scope in the propagation of rattan seedlings which usually could not germinate well under ordinary conditions due to dormancy
Prospects of Citrus sinensis (masumbi) cultivation in Haryana State, India
Get PDFThe empirical study on prospects of Citrus sinensis cultivation by farmers indicated that overall prospects of masumbi (C. sinensis) crop were medium to high since 77.5% respondents belonged to these categories. Majority of respondents agreed that better market facilities (weighted mean score 2.72), increased purchasing power of people (2.65), better fruit quality (2.62), better economic return (2.53) and increase in demand of fruit were the major prospective aspects for its wider adoption (2.53), whereas better technical support (1.20) and better credit facilities (1.08) both were not up to the desired level as expressed by the farmers. So the government should make concerted efforts to further strengthen the highly prospective aspects like better marketing facilities, cultivars of better quality fruits at farm gate or village level. On the basis of result obtained, the prospects of masumbi (C. sinensis) cultivation may be high in future
Integrated management approaches for controlling root rot of bael caused by Fusarium solani
Get PDFAn experiment was carried out to find out the effective management practices to control the recently recorded pathogen (Fusarium solani) inciting root rot disease in Bael. Rampant incidence due to this pathogen is resulting in excess damage and reduction in acreage. Out of six fungicides screened in vitro, Topsin-M and Bavistin stood at first place in inhibiting the mycelial growth of F. solani. Topsin-M showed 100% inhibition at 50 ppm concentration whereas Bavistin showed 100% inhibition at 150 ppm concentration. Bavistin and Topsin-M as seed dressers effectively protected pre and post emergence seedlings mortality to the tune of 68.75 and 70.95%; 65.00 and 67.54%, respectively. Pre-sowing drenching of soil with Bavistin (0.4%) reduced the pre-emergence mortality from 26.50 to 8.25% and post-emergence mortality from 39.00 to 16.25%. The integration of seed treatment and pre-sowing drenching resulted in 72.51% control of pre emergence mortality and 82.92% control of post emergence mortality. In dual culture method, maximum inhibition of mycelial growth was recorded with Trichoderma harzianum (72.18%) followed by T. viride (67.70%). Glomus mosseae in combination with T. harzianum was found very effective against F. solani under screen house conditions as minimum pre emergence mortality (10.00%) and post emergence mortality (13.25%) against control where the values were 27.25% and 40.25%, respectively. The studies and results compiled here in provide an explanation for the potential of selected fungicides and antagonists in the control of bael root rot disease
Plethora (Novaluron + Indoxacarb) insecticide for the management of tomato fruit borer complex
Get PDFDuring the past three decades, efforts have been made to reduce the risk of human exposure to pesticides specially insecticides. There is a great demand for safer and more selective insecticides that spare natural enemies and non target organisms. The present investigation was conducted during rabi season 2009 and 2010, to test the effectiveness of recently developed new ready mix insecticide Plethora (Novaluron 5.25 %+ Indoxacarb 4.5% SC) along with other insecticides against Helicoverpa armigera Hub and Spodoptera litura Fab. infesting tomato. It is observed that Plethora @ 875 ml/ha recorded only 3.75% fruit damage, while in control plot it was 45.6%. Though highest cost benefit ratio (1:6.17) was obtained when Plethora was applied at 825 ml/ha. Independently novaluron performed well specially against S. litura and indoxacarb showed better performance against H. armigera but lamda-cyhalothrin expressed comparatively lower performance than other selected insecticides which received 28.30% fruit infestation
