Therefore, it is necessary to explore intrinsic resistance in Brassica juncea germplasm for suppression of this disease. In the present study, phenotyping of exotic and indigenous collections of Brassica juncea was done against thirteen diverse A. candida isolates in cotyledon and true leaf plants under controlled conditions and in adult plants on field at different locations during three consecutive mustard crop seasons (2019–2022). Among 311 lines screened of B. juncea, 59 germplasms were found immune under artificial and field screening against various isolates of A. candida. Five accessions, EC766193, IC265495, EC766061, EC766595 and IC443623 of B. juncea were identified to express immune response for six of the pathogenic isolates, whereas, for rest of the isolates they expressed high to moderate resistance. Moreover, correlation study showed positively co-related resistance levels among adult plant and true leaf stage of development in B. juncea (r = 0.859, p< 0.01). The GGE biplot elucidated 69.4% of the total variation and visually displayed the resistance and stability for B. juncea accessions against white rust disease. These new sources of host resistance for virulent pathotypes of A. candida are critically important and will help to create a strong credential for discerning and mapping of resistance linked gene/QTL and to sustainably manage this disease in India.Not Availabl

No full textNot AvailableIn developing nations such as India, malnutrition is a major nutritional and health challenge. Biofortification has the potential to be an effective instrument in India’s attempts to combat malnutrition. Expert opinion must be used to evaluate the factors related to the promotion, distribution and adoption of biofortified crops. The analytical hierarchy process (AHP) is one of the most often employed decision-making methods. However, conventional AHP is incapable of identifying ambiguity in human judgements. Fuzzy AHP has already been devised to overcome this limitation. Fuzzy AHP necessitates information in pairwise comparisons, which is not always easy to gather. In this context, the Fuzzy AHP technique based on the genetic algorithm has been proposed, which can compute the priority weight without using a pairwise comparison matrix by directly dealing with expert-provided data. The proposed approach has been illustrated using the opinions of 1600 farmers from Odisha, IndiaNot Availabl

No full textNot AvailableA mammoth amount of tea pruning litter (TPL) is generated through the pruning of the tea plant and kept on the soil surface which makes the soil sick due to the accretion of allelochemicals from it. Therefore, appropriate management of TPL is very much crucial. This study was conducted to assess the role of tea pruning litter biochar (TPLBC) as a soil conditioner towards the growth and regulations of two popularly grown tea cultivars (TV23 and S.3A/3) in India. Altogether twenty-nine (29) parameters comprising functional groups, plant biomass, and physiological and biochemical properties have been reported in this study to understand the feasibility of TPLBC for tea cultivation. TPLBC amendment of 400 kg ha−1 was best suited for the used cultivars, leading to an increase in chlorophyll content, photosynthetic rate, stomatal conductance, transpiration rate, and water use efficiency by 25.68%, 49.61%, 84.00%, 126.93%, and 3.87% respectively. The maximum increase in plant total biomass, shoot biomass, and root biomass was attended at 110%, 31%, and 117%, respectively at 400 kg TPLBC ha−1 over control. The results also revealed an increase in the content of sugar, starch, phenol, total polyphenol, and amino acids with an increasing dose of TPLBC up to 400 kg ha−1. However, with 500 kg ha−1 TPLBC, plant biomass, and polyphenol content were decreased but oxidative stress was increased. Considering all the 29 variables it can be concluded that the soil amendment with 400 kg TPLBC ha−1 was most promising for both TV23 and S.3A/3 clones.Not Availabl

No full textNot AvailableFusarium is one of the important genera of plant parasitic fungi responsible for causing wilt disease in Soybean. The present study was conducted to identify the virulent isolate of the pathogen and to assess their pathogenicity in Soybean cv. Basara. About 10 different Fusarium isolates were collected from the division of Plant Pathology, ICAR- IIOR, Hyderabad, and were assessed for their pathogenicity in Soybean cv. Basara to identify the virulent isolate against the crop using three different pathogenicity tests viz., filter paper method, artificial inoculation method, and sick pot method. Among the 10 different isolates tested for their virulence under three different pathogenicity tests, the Fusarium isolate, CF II was reported to exhibit a higher disease index and wilt incidence in the crop, which has been designated as the virulent isolate against the crop. The pathogenic Fusarium isolate, CF II was characterized using molecular methods based on ITS PCR and confirmed as Fusarium oxysporum.Not Availabl

No full textNot AvailableStudies on storage of turmeric powder packaged in a three layered metalized polyester covers (12μ
polyester + 12μ metalized polyester + 80μ polyethylene (LDPE)) and stored at different temperatures like
ambient, 30, 40 and 50 °C in different BOD incubators for a storage period of 10 weeks were studied.
The results of the study indicated that the moisture content of turmeric powder reduced when stored at
30, 40 and 50 °C and maximum reduction of moisture content was 17.49% when stored at 50 oC. While
for ambient stored turmeric powder, the moisture content was found to increase by 7.34%. There was no
change in essential oil content of turmeric powder at ambient and 30 °C which was maintained at 4% in
both the cases. But a reduction in essential oil content by 10% was observed at 40 and 50 °C towards the
end of the storage period. A decrease in oleoresin content with increase in storage temperature was
observed and the minimum reduction of 8.50% was obtained for the ambient stored turmeric powder and
maximum reduction of 19.76% was observed when stored at 50 °C. Curcumin content reduced by 4.58%,
6.26%, 7.33% and 10.38% for ambient, 30, 40 and 50 °C storage conditions, respectively towards the end
of 10 weeks of storage. Volatile oil constituents in the essential oil of turmeric powder like α-terpineol,
zingiberene decreased during storage while constituents like ar-curcumene and curlone, ar-tumerone
increased during the storage of turmeric powderNot Availabl

No full textNot AvailableThe work was aimed at developing an energy-efficient solar hybrid dryer with a biomass-based gasifier heat backup suitable for drying shrimps even during off-sunshine hours. In this dryer, water was utilized as a sensible heat storage (SHS) material as well as heat transfer fluid and biomass gasifier as an indirect backup heat source. The performance of the solar-gasifier hybrid dryer was assessed by drying shrimp (Metapenaeus dobsoni) samples and compared it with solar, and gasifier modes. Shrimp obtained the desired moisture content of 15.09 %, 13.46%, and 14.77% (w.b.) in 9 h, 6 h, and 6 h of drying in solar mode, gasifier mode, and solar-gasifier hybrid drying mode, respectively. The average drying rate of the solar, gasifier and hybrid modes of drying were 0.33 g/ g dm.h, 0.46 g/g dm.h, and 0.47 g/g dm.h, respectively. Results revealed that the evacuated tube solar water collector harnessed 193104 kJ and 160185 kJ of heat energy during sunshine hours under the solar and hybrid mode of operation. The maximum drying efficiency of 34.97%, 35.62%, and 41.66% was obtained for gasifier mode, solar mode, and hybrid mode of shrimp drying. The economic evaluation revealed that the hybrid mode of operation is highly economical with the annual savings of $10983.06 and the lowest payback period of 0.62 years.Not Availabl
