Background/Objectives: French marigold (T. patula) hardy annual, about 30 cm tall, forming a bushy plants are grown as a loose flower and a garden flower. Four male sterile lines and 18 diverse pollinators as tester were used to produce 72 F1’s. These crosses and parents were evaluated for different ornamental characteristics. Methods/Statistical Analysis: These F1 hybrids along with 22 parental lines were evaluated during the summer (2009) and rainy season (2009) in Randomized Block Design. Highly significant variances for all the traits indicated the sufficient variability was observed in the parental material for all the characters under study. Findings: Among male sterile lines, ms8 (summer season) and ms9 (rainy season) proved good general combiners, while testers Spray Mix -1, Bonita Bolero and Safari Queen were the best general combiners for both the seasons. However, cross combinations viz. ms8 x Hero, ms10 x Hero, ms10 x Cupidon Yellow, ms8 x Double Dwarf Lemon was the best in terms of specific combining ability during the summer. Whereas, during winter the combinations viz. ms9 x French Bonita-3, ms10 x French Bonita-3, ms9 x Bonita Bolero, ms8 x Sunkist and ms9 x French Bonita-2 were best specific combiners. In both the seasons, the ration of σ2 GCA/σ2 SCA was less than unity for all the characters showing the preponderance of dominance variance. Applications: Marigold is especially used for festive occasions, marriages, religious ceremonies, social function and in landscape plans because its having a wide range of attractive colours, shape and size having good keeping quality. Now a days, marigold is used as a source of pigment for poultry feed. Caretonoids is used as poultry feed mix and food colourant. Lutin, is major component of Caretonoid is having therapeutic values. Marigold cultivation controls the nematode population in as well as mosquito repellant products are also being used. The mean sum of square for parentsvs crosses in this study for all the traits during summer and rainy season indicated the presence of heterosis. Thus it is obvious that heterotic effects represent an important resource in hybrid breeding of French marigold.Keywords

Backgrounds/Objective: Preservation of Kinnow (Citrus nobilis × Citrus deliciosa L.) juice by using edible preservatives is needed to ensure nutritional security of common people. Suitability of preservation techniques to extent the storage life through maintenance of microbial load and nutritional strength up to desirable level is essential. Methods/Statistical Analysis: The study was conducted through analysis of TSS, acidity, Vitamin-C, and sugar while biological study was carried out through microbial load and browning. Findings: Kinnow fruit juice can be stored up to 30 days without loss of nutritional quality if 0.05% of Potassium metabisulphite or 0.05% sodium benzoate is used as preservatives whereas minimum and desirable browning (0.093) and microbial load (2.60 X 105) was reported when juice was treated with 0.1% KMS at 30 days of storage. Application/Improvements: The research outcome of present investigation suggests for storage of Kinnow fruit juice for 30 days with minimum quality loss by using 0.05% Potassium metabisulphite or sodium benzoate under ambient condition.Keywords

The present study was undertaken for studying constraints of organic farming practices in Bikaner district of Rajasthan. This district was selected purposively as it has large area under rainfed farming and mostly fertilizers and pesticides are not being used in this area. For the study 30 farmers practicing organic farming were selected. The results revealed that the important constraint faced by the farmers of study area were non-availability of sufficient organic manure, low productivity of organic farming, lack of selling outlets, marketing of organic farming produce is the main problem, certification facility is not available of organic farming, unawareness of organic farming, price of the organic products is the high and cost of certification organic farming is high. The study of constraints revealed that about 81.5 per cent farmers of the study area faced the problem about no availability of sufficient organic manure. The problem faced by the farmer is related to difficulty in adoptions of organic farming was worked out about 61.9 per cent. About 81.03 per cent farmers reported the problem of selling.Keywords

The present study has been undertaken to study the damage and recovery capabilities of different organs (liver, kidney and gill) of fish, Channa punctatus after sub chronic exposure to three sublethal concentrations of 4-nonylphenol and 30 days recovery period. To see genotoxic effect and appraise the recovery capabilities Micronucelated Cell (MNC), Binucleated Cells (BNC) and Aberrant Cell (AC) frequency by micronucleus assay and tail moment was evaluated by using the comet assay. The exposure was given for 90 days and the effect was seen after 30, 60 and 90 days of exposure. Three sublethal concentrations were decided after calculating the safe application rate. Exposure results in increased frequency of MNC, BNC and AC in all the tissues. Gill tissue was found to be more sensitive to 4-nonylphenol exposure. The effects show that 4-NP can cause water quality deterioration, resulting in deleterious effect on the health of fish. After 90 days exposure, 30 days recovery was also observed and significant reduction in the values of both the parameters was observed showing a great capacity of C. punctatus to restore its DNA integrity.Keywords

Skew slabs have various applications, e.g. as floor of bridges and buildings. This is pertinent when it is not possible to cross a river or gap at an angle of 90°. Design aids and plans suggested by various codes are applicable for standard skew angles, i.e. 15°, 30°, 45°, etc. with selective spans only. However, in actual practices, several cases are encountered, wherein skew angle and aspect ratio of the slab panel do not fit the recommended guidelines. This occurs due to the very high land cost and space limitations. The present study proposes an analytical model for the design of skew slabs with any skew angle and aspect ratio. The developed model indicates that skew slabs simply supported along two opposite parallel sides and free along the other two sides are suitable for the construction of bridges having short diagonal larger than the span. The developed model validates the assumptions considered in terms of collapse loads and crack patterns experimentally and numerically. This shall facilitate engineers during the design of skew slab bridge for any skew angle and aspect ratio, without deviating from the alignment of the road.Keywords

The advent of COVID-19 waves has continued since 2020, and we are here to accept that as individuals we have to learn to combat and recover from this infection effectively by COVID appropriate behaviour of quarantine, complete schedules of vaccination, masking, hand washing and a good dietary intervention to enable good recovery. This compiled review from the working group of Nutritionist of Indian Dietetic Association (2019-2022) will serve as a ready reference for dietitians, physicians and healthcare professionals in different settings; to advise the right diet and adequate nutrition for the adult COVID patients in different stages of the infection.The key points include- in mild intensity disease, while the patient is quarantined and home bound, the emphasis is on consuming adequate nutrient dense foods supporting the immune system, as well as providing adequate hydration. The role of traditional practices and immune boosting nutrients will also help in supporting the mildly affected patient. In case of moderate illness, the demand consequent to running fever and cough needs to be met. The needs of the elderly population and patients with co-morbidities would be very specific and critical, and that needs to be thoroughly monitored. The management of a patient with critical illness, needing intensive care support, will need customized parenteral and enteral nutrition support. The dietary specifications in case of co-morbidities, for those needing ventilator support and ECHMO have been enumerated. This paper clearly brings out the need for an individualized nutrition support delivered by a qualified Nutritionist as a part of health care team in each of the stages of the COVID-19 infection, and is a strong recommendation.Keywords
