Phytochemical analysis of Murraya koenigii collections from Himachal Pradesh
The experiment was conducted to evaluate the phytochemicals of Murraya koenigii (L.) Spreng leaves collections from 10 different sites of three districts (Kangra, Hamirpur and Bilaspur) of Himachal Pradesh. The extraction and estimation of collected leaves was carried out in the Laboratory of Department of Forest Products, College of Forestry, Dr. YS Parmar university of Horticulture and Forestry, Nauni, Solan during the year 2022-23. The data recorded were subjected to statistical analysis under Completely Randomized Design (CRD). Analysis of variance was carried out and critical difference at 5 percent level of significance. It was reported that maximum chlorophyll a content was found in the sample collected from site Jhaniari (District Hamirpur) -T10 i.e. (0.88 mg/g), chlorophyll b was found in the sample collected from site T3 Nadaun (Hamirpur) -(0.65 mg/g) and maximum value for total chlorophyll was recorded in the sample collected from site Jhaniari (Hamirpur) - T10 i.e. (1.44 mg/g). Maximum carotenoid content was recorded in samples collected from Dheera (District, Kangra) -T1 i.e. (0.71 mg/g) and minimum was recorded in Jhaniari (District, Hamirpur) – T10 i.e. (0.55 mg/g). Among different sites alkaloids was present and saponin was found to be absent. Maximum phenolic content was found in Jhaniari (district, Hamirpur) -T10 i.e. (417.68 ± 0.92 GAE/g) and minimum was recorded in Dheera (Kangra) -T1 i.e. (291.39 ± 1.33 GAE/g). Maximum flavonoid content was recorded in Jhaniari (Hamirpur) -T10 i.e. (324 ± 0.96RE/g) and minimum was recorded in Dheera (Kangra) -T1 i.e. (204 ± 1.79 RE/g).
Resistance Profiling of Mungbean varieties against Mungbean Yellow Mosaic Virus under natural condition
Mungbean yellow mosaic disease is caused by the Mungbean yellow mosaic virus or MYMV that causes damage to Mungbean plants. The white fly-Bemesia tabaci is the insect vector that transmits the virus. Overall, Mungbean yellow mosaic disease is one of the main destructive diseases of Mungbean species and varieties. The current study was conducted to screen 36 genotypes of mungbean germplasm against mungbean yellow mosaic virus disease under natural field conditions. In the field, all the genotypes were subjected to natural infection by infectious whiteflies. The maximum and minimum disease incidences (%) were observed in GP-276 (18.08%) and BRM-8-1 (0.47%) respectively at 55 DAS. The maximum and minimum disease severities (%) were observed in GP-276 (56.3%) and BRM-8-1 (0.6%) respectively at 55 DAS. The maximum and minimum AUDPC (A) values were observed in Banka Local Mung-1 (126.2) and BRM-8-1 (3.9) respectively. Among all the 36 genotypes screened, BRM-8-1 (0.6%) was observed to be resistant (R) to yellow mosaic disease (YMD). The three genotypes namely Meha, IPM-409-4, IPM-2-14 were found to be moderately resistant (MR) with disease severities of 9.3%, 6% and 6.7% respectively. The two genotypes namely GP-276 and DMG-1105-1-2 were found to be highly susceptible (HS) with disease severity percent of 56.3 and 53.3 respectively. The results indicated that BRM-8-1 can be used as donor MYMV resistant parent to develop commercial high yielding resistant varieties. GP-276 and DMG-1105-1-2 can also be used as MYMV susceptible varieties in future breeding programmes.
Pancytopenia in Dogs – Mechanics to Differentiate Sepsis with Non-sepsis
Pancytopenia manifests as a reduction in circulating myeloid, erythroid, and megakaryocytic cell lines, with causes ranging from infectious, neoplastic, and immune-mediated diseases to sepsis and various drugs. This study endeavors to pinpoint the etiological agents of pancytopenia and establish parameters for distinguishing sepsis from non-sepsis cases. Clinical signs indicative of bleeding tendency and sepsis were identified, and animals exhibiting pancytopenia upon hematological analysis underwent further evaluation, including hemato-biochemical analysis, bone marrow cytology, PCR analysis, and flow cytometry, to ascertain the underlying causes. Discriminant function analysis was performed on 12 parameters obtained from 37 pancytopenic dogs and 20 healthy dogs, with the objective of distinguishing between sepsis and non-sepsis cases. Mean fluorescence intensity levels against platelets were recorded at 24.6% and against RBCs at 26.1%, confirming the presence of immune-mediated thrombocytopenia and anemia. Over a span of 2 years, the incidence of pancytopenia was higher in young animals. In our study, the identified etiologies among pancytopenic dogs were predominantly hemoprotozoan infections, accounting for 62% (41 dogs), followed by immune-mediated diseases at 24% (16 dogs). Significantly, five parameters - erythrocyte count, leukocyte count, platelet count, temperature, and heart rate were identified as significantly discriminatory between dogs with sepsis and those without sepsis. The higher incidence of pancytopenia in young animals can be attributed to infectious and secondary immune-mediated diseases. Among the different hemato-biochemical, physical parameters leukocyte count followed by RBC count was found to be the suitable parameters to differentiate sepsis and cases without sepsis in pancytopenic cases. This was also confirmed by the area under the curve of more than 80% and 78%, respectively, in the receiver operating curve, and 100% of originally grouped cases were correctly classified at a 99% confidence interval.
Optimizing Weed Control in Onion Cultivation for higher yield and returns: Techniques and Effectiveness
Weeds pose a major problem for the raising of crops and compete with the crop for around 26 essential resources, among them moisture, nutrients, space, and light are significant. They cause a substantial percent of decrease in both the yield and quality of the produce. In addition, weeds serve as alternative hosts for different insects and pathogens, which are the basis of causing pests and diseases respectively. Onions are densely planted because they have a shallow root system. It requires more labour with skill and patience to remove the weeds without disturbing the root system. Negligence is directly proportional to crop economics. Currently, the availability of labour is meagre. In such situations, following of more than one method of weed control like chemical, cultural, biological, or other methods which are directly enhances the yield and quality of the produce by following cost-effective methods are need of the present conditions. To achieve this using integrated weed management strategies can enhance crop yields through the suppression of weeds. This paper aims to identify the appropriate herbicides and their application rates for effective weed management, under different methods of planting and soil conditions and explains the other suitable and cost-effective weed management methods.
The effect of background fertilizers on the response of durum wheat to water stress.
To determine the impact of fertilizer (Fosfactyl) on the growth of durum wheat during water stress. Our research has indicated the importance of chemical fertilizer (Fosfatyl) in improving durum wheat's behavior by directly impacting abscisic acid (ABA) expression. Most plant tolerance to water stress is attributed to a phytohormone. The amount of abscisic acid is increased by plants when faced with adverse stress. Plant resistance increases under long-term adversity stress due to the accumulation of abscisic acid (ABA) in plants. Water stress treatment affects the response variability of three durum wheat genotypes (Simeto, Hedba-3, and GTA dur) differently. By analyzing multiple physiological and biochemical parameters, the tolerance strategy adopted by each variety was characterized. Fosfactyl under water stress resulted in a change in seedling physiology, as well as an accumulation of proline, proteins, and sugars, which led to an increase in antioxidant enzyme activity. The experimental work has demonstrated that the response of durum wheat varies from variety to variety and is based on the fertilizer applied. The examination suggests that certain parameters are reliable indicators of tolerance and can handle the pressure of water stress.
