Effect of Ashwagandha on Somatic and Gonadal Development in Cirrhinus mrigala under Sodic Soil Condition
The current investigation was conducted for a period of 90 days to examine the effect of two different doses of Ashwagandha (2% and 3%) on somatic and gonadal development in Cirrhinus mrigala. A total of 270 fish with mean length-weight of 27.49±3.36 cm and 235.5±60.29 gm were stocked randomly into nine earthen trial ponds and distributed as 30 fish in each pond. Whole experiment was of 3 different treatments, T1 (Control), T2 (2% Ashwagandha added diet) and T3 (3% Ashwagandha added diet) and each treatment was designed with 3 replications. During the experiment values of water quality parameters such as pH, Temperature, Dissolve Oxygen and TDS were found within optimal range. Gonadosomatic Index (GSI) for both male and female in April found maximum in T3 and their values were found 2.04±0.1 and 6.73±0.12 respectively (P<0.05). Values of biological indices of male C. mrigala such as regression coefficient “b” (2.44), condition factor (1.08) and SGR (1.08) was found maximum in T2 while in female C. mrigala, regression coefficient "b" (2.1) and SGR (0.256±0.004)was found maximum in treatment T3. In conclusion, 3% Ashwagandha added diet could be a option for obtaining appropriate somatic and gonadal growth of female while in male 2% Ashwagandha supplemented diet could be appropriate for somatic growth and 3% for gonadal growth.
Influence of organic supplements on growth and yield attributes of brinjal (Solanum melongena L.) cv. Pusa Purple Cluster
To assess the response of various organic nutrient sources in brinjal cultivation, an experiment was conducted at the Organic Block of the Research Farm, Department of Vegetable Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out using a Randomized Block Design with three replications and eight treatments: T1 – absolute control, T2 – farmyard manure (FYM) @ 10 t/ha, T3 – vermicompost (VC) @ 5 t/ha, T4 – FYM @ 5 t/ha + VC @ 2.5 t/ha, T5 – Beejamrit + Jeevamrit, T6 – FYM @ 10 t/ha + Beejamrit + Jeevamrit, T7 – VC @ 5 t/ha + Beejamrit + Jeevamrit, and T8 – FYM @ 5 t/ha + VC @ 2.5 t/ha + Beejamrit + Jeevamrit. Among the different organic treatments, T7 outperformed others in most of the yield and yield-contributing traits and also showed the lowest incidence of insect pests and diseases. The maximum fruit breadth, fruit weight, and marketable fruit yield were recorded under T7. However, in terms of quality parameters, T8 recorded the highest ascorbic acid content and total soluble solids (TSS), which were statistically at par with T7. Therefore, the application of vermicompost @ 5 t/ha along with Beejamrit (as seed treatment) and Jeevamrit (as soil drench and foliar spray @ 5%) can be recommended for improved growth, higher yield, reduced pest and disease incidence, and sustainable crop production under changing climatic conditions.
Consumption of Wild Edible Fruits and Vegetables: A Case Study of Khirsu Block of Pauri Garhwal District, Uttarakhand
Wild edible plants (WEPs) refer to non-domesticated species that grow naturally without human cultivation. It plays a crucial role in enhancing nutrition, poverty eradication and ensuring food security, particularly in rural regions, yet they remain largely underutilized and understudied. The present study explores the diversity and consumption of wild edible fruits and vegetables among the local community of Khirsu Block in Pauri Garhwal District, Uttarakhand, India. Ethnobotanical data were collected through structured interviews with local inhabitants across different age groups, and plant specimens were identified using regional floras and standard monographs. A total of 46 wild plant species representing 26 botanical families were recorded as edible and phytofoods in the current study. Species diversity of wild edible species was highest for fruits (32 species) followed by vegetables (14 species). These 32 edible fruit species belong to 16 families and 14 edible vegetable species from 10 families. Among fruits, Rosaceae was the most prominent family, while Polygonaceae dominated among vegetables. Leaves were identified as the most commonly consumed plant part in wild edible vegetables. The research highlights the significance of WEPs in sustaining local diets and emphasizes the urgent need for conservation strategies and awareness programs to safeguard traditional knowledge and promote the sustainable use of these valuable resources.
Effect of Plant Spacing, Date of Transplanting and Weather on Epidemiology of Early Blight of Tomato in the Mid-hills of Himachal Pradesh
Early blight of tomato caused by Alternaria solani is an economically important disease-causing significant yield loss at all stages of development in tomato. It is a major constraint for tomato production in Himachal Pradesh both under open field and protected cultivation. The prevailing conditions of climate change and shorter winter spells have further aggravated the disease severity and consequent economic losses. In this study, field experiments were carried out to examine the development of early blight in tomato with respect to weather conditions during kharif and zaid seasons in 2021 and 2022 at CSKHPKV (Palampur, H.P.). The effect of plant spacing and date of transplanting was also studied. Tomato seedlings transplanted in the 1st week of April (2nd April) and at wider spacing (60x60 cm) resulted in higher fruit yield and less disease severity as compared to late transplanted crop (12th April) and close spacing (30x45 and 45x45cm) under both open field condition and polyhouse conditions. Early blight severity was found to be significantly positively correlated with maximum temperature and morning RH, while it negatively correlated with rainfall. Temperature was observed as the most important environmental factor in the development of disease.
Influence of pre harvest treatment of salicylic acid and sodium nitropruside on antioxidant enzymes and gene expression of ethylene biosynthesis, ethylene receptor and ethylene transcription factor genes in banana cultivars
To better understand the impact of salicylic acid and sodium nitropruside on banana cultivars we were conducted an experiment. In this experiment salicylic acid 750 µM and 1000 µM, sodium nitropruside 0.5 mM and 1 mM were sprayed on Grand Naine and Tella Chakkerakeli banana bunches at 15 days prior to harvest. After harvest banana hands were kept for storage studies at ambient room temperature (25±2°C and 70±2 % RH). The results indicated that Grand Naine banana (shelf life 15.1d) fruits had responded to ethylene inhibitors considerably as compared to Tella Chakkerakeli banana (shelf life 8.5d). However, among different pre harvest treatments, salicylic acid @ 1000 μM followed by salicylic acid @ 750 μM were found to be more effective in retention of cell wall degrading enzyme such as pectin methylestarase and antioxidant enzymes, peroxidase and catalase. Ethylene biosynthesis (MaACO1, MaACO2, MaACS1, MaACS2, MaACS3 and MaACS4), ethylene receptor (MaERS1) and ethylene transcription factor (MaERF1) gene expression in banana cultivars treated with salicylic acid @ 1000 µM (which was evolved as optimum concentration of this experiment) against untreated banana was acknowledged significant results. In this current research the expression of all the genes were up regulated with the ripening process in general while it was down regulated (sometimes completely repressed) in both the cultivars treated with ethylene inhibitor salicylic acid @ 1000 μM as compared to untreated banana fruits.
