Studies on Comparative Analysis of Salicylic Acid, Paclobutrazol and Potassium Chloride Seed Priming in Enhancing Seed Quality of Soybean Seeds Under Salinity Stress
Salinity stress is a major abiotic factor that adversely affects soybean (Glycine max) growth and productivity. Seed priming is a cost-effective and sustainable approach to enhance crop performance under stress conditions. This study investigates the potential of three seed priming agents, namely Salicylic acid (100, 250, 500, 1000µM), Potassium chloride (50, 100, 250, 500mM) and Paclobutrazol (100, 250, 500, 1000µM), in alleviating the negative impacts of salinity stress of 6dS/m on soybean seed growth and development. The physiological parameters such as, germination, mean seedling length, seedling dry weight, Vigor index-I and II and early vigor parameters viz, mean germination time, speed of germination and coefficient of velocity of germination were compared with hydro-primed and unprimed seeds. The results of the study demonstrated that when salicylic acid primed seeds at 1000µM were exposed to 6dS/m, has significantly enhanced the seed germination (80%) and other physiological parameters such as MSL (13.22cm), vigor index- I and II (977.86 and 1036) reduced MGT (2days) in a salt susceptible variety, SL958 as compared to KCl and Paclobutrazol. However, KCl at 100mM and PBZ at 500 µM had higher germination % as compared to other doses. Salicylic acid priming enhanced the antioxidant defense system, reducing oxidative damage caused by salinity stress. Hence, current findings suggest that the use of salicylic acid as a seed priming agents can be a promising strategy for mitigating salinity stress in soybean cultivation.
Heterosis and Inbreeding Depression Studies in Mungbean [Vigna radiata (L.) Wilczek]
Twenty eight mungbean hybrids derived from 8 x 8 diallel excluding reciprocal crosses were studied to know the magnitude of heterobetiosis, standard heterosis and inbreeding depression for yield and its component characters in mungbean. The magnitude of heterobeltiosis and standard heterosis was high for seed yield, number of pods per plant, number of clusters per plant and number of primary branches per plant. The crosses Vaibhav x Asha for heterobeltiosis and K 851 x OUM 11-5 for standard heterosis showed significant and the highest value for seed yield and its important component traits. Only one heterotic cross i.e. K 851 x Pant-M 4 for seed yield did not show inbreeding depression for same trait. Further this cross did not show inbreeding depression for most of the characters.
Correlation of major soil enzymes with population dynamics of Ralstonia solanacearum under different ginger based crop rotation system.
Ginger (Zingiber officinale Rose) is considered as one of the most important commercially grown spice crops. Green wilt disease caused by pathogen Ralstonia solanacearum is one of the devastating disease causing huge economic losses among the ginger growing communities. In hill regions of West Bengal, ginger is mostly grown organically and management of the pathogen and disease is challenging. Therefore, crop rotation with non-host crops plays a vital role in management of such soil borne pathogen by reducing the population load. Additionally left over compost and incorporation of FYM as an organic source of nutrients in organic cultivation of crop not only helps in increasing organic matter content and enhancing soil quality but also helps in enhancing various enzymatic activities. This enzymatic activity has been used as an indicator in enhancing beneficial soil microflora which helps in reducing the soil borne pathogens. The finding of the present experiments indicated cabbage-based crop rotation system with ginger as a beneficial one as it helps in reducing the pathogen population during the active tillering stage which is the crucial stage of pathogen infection. Also a significant negative correlation of R. solanacearum population with Dehydrogenase and β- glucosidase enzymes was recorded however no significant correlation was observed with the Acid phosphatase enzymes.
Compatibility study of entomopathogenic fungus (Beauveria bassiana) with promising plant oils
In recent years, plant oils and entomopathogens play a potential role in eco-smart management of insect pests due to their eco-friendly, effective and specific nature and hence needed to be prioritized as an alternative to chemical control in the pursuit of a healthy nation. The present investigation was made to study the compatibility of Beauveria bassiana with four plant oils at three different concentrations (neem oil @ 2.00, 1.00, 0.50 per cent; karanja oil @ 2.50, 1.00, 0.25 per cent, jatropha oil @ 4.00, 2.00, 0.50 per cent and citronella oil @ 0.30, 0.50 and 1.00 per cent). It was studied considering four aspects viz., radial growth, conidial production, sporulation and per cent inhibition for compatibility test. It revealed that citronella oil @ 0.30 + B.bassiana 1x107 conidia/ml combination was highly compatible with T value 79 followed by 74 and 72 in neem oil (0.50%) + B. bassiana (1x107 conidia/ml) and citronella oil (0.50%)+ B. bassiana (1x107) conidia/ml) respectively. Otherwise, jatropha oil (4.00%) + B. bassiana(1x107 conidia/ml) recorded the lowest T-value (45.70) indicating less compatibility showing moderate toxicity. The highly compatible combination of citronella oil @ 0.30 + B.bassiana (1x107 conidia/ml)would be a potential bioagent in pest management andcould enhance its virulence against insects at low cost too.
Phenotypic and Genetic Characterization of Diara Buffalo of Bihar
Diara buffaloes are dual purpose lesser known population distributed around south and north Gangetic plains of Bihar. These buffaloes are adapted to environmental conditions of Bihar, India and its genetic constitution getting diluted due to use of semen of other breeds. The phenotypic and genetic characterization studies assist to policy makers to take decisions for conservation and rational implementation of breeding programme. A total of 200 animals from all surveyed villages were included to record information on various management practices, physical characteristics and production and reproduction performances using structured questionnaire. The molecular characterization using FAO recommended 10 microsatellite markers were carried out on 50 unrelated individuals of buffaloes. Different measures of genetic diversity were estimated using various softwares. The average number observed of alleles (Na), Effective number of alleles (Ne), Shannon Information Index (I), Observed heterozygosity (Ho), Expected heterozygosity (HE), Average heterozygosity (HA), Polymorphism Information Content (PIC) at different microsatellites loci in Diara buffalo population were obtained 7.4, 5.7, 1.8, 0.68, 0.82, 0.80 and 0.79, respectively. The allele distribution followed the normal L-shaped form suggesting that the breed had not encountered a genetic bottleneck in the recent past. The result shows sufficiently high genetic diversity in the population. The information generated in this study may aid in formulation of effective breeding and conservation programme. However, genetic diversity study of Diara buffalo needs to be extended to include more microsatellites in a large sample size to further validate the research.
