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.
Floral Biology and Pollination Dynamics of Newly Introduced Apple (Malus × Domestica Borkh.) Varieties
Apple is renowned for its nutritional as well as economical value. The success of newly introduced apple varieties highly depends on a clear understanding of their floral biology and pollination behaviour, which are crucial for ensuring optimal fruit set, yield and quality. Therefore, the present investigation was carried out at Regional Horticultural Research and Training Station, Mashobra, Shimla, Himachal Pradesh, India during the year 2023 and 2024 to study the floral biology of different apple varieties and to study the extent of fruit set under different modes of pollination. Five main varieties viz. Red Velox, Red Cap Valtod, Jeromine, Scarlet Spur II and Modi along with three pollinizing varieties viz. Auvil Early Fuji, Dark Baron Gala and Redlum Gala were selected for different studies. Marked variations in the floral characters like flower size, petal arrangement, stamen number, pistil length and ovary diameter were recorded. Flowering duration was longest in Dark Baron Gala (15 days) during 2023 and 2024 and shortest (10 days) in Scarlet Spur II and Red Velox in both years. Maximum (88.78 %) mean pollen viability was observed in 1 per cent acetocarmine and minimum (87.70 %) in erythrosine B. In vitro pollen germination was maximum (61.83 %) in Dark Baron Gala and minimum (40.86 %) in Scarlet Spur II. Average fruit set was found to be highest (63.66 %) under open pollination conditions followed by controlled/hand-pollination conditions (51.13 % and 53.85 %) during 2023 and 2024 and lowest (22.33%) under bagging. Similarly, mean fruit retention was highest (73.14 %) under open pollination conditions followed by controlled/hand pollination conditions (54.90 % and 69.42 %) during 2023 and 2024 and lowest (59.05 %) under bagging. Maximum values of fruit length, breadth and weight were recorded under bagging condition followed by open pollination, whereas, minimum fruit length, breadth and weight under controlled/hand pollination conditions. On the basis of present investigation Dark Baron Gala showed all the characteristic of ideal pollinizing variety viz. synchronization in flowering, pollen viability, pollination behaviour and extent of fruit set with over all commercial accessibility.
Impact of integrated nutrient management on micronutrients uptake in pearl millet-wheat cropping system under saline water irrigations
The combination of organic manures and fertilizers played a crucial role in improvement of soil physico-chemical properties, transformation and distribution of macro and micro-nutrients under various cropping system. The non-availability of good quality water for irrigation especially in arid and semi-arid regions of Haryana led to development of soil salinity that interferes with sustainable crop production. The study was conducted with the aim to explore the appropriate combination of manures and fertilizers under such conditions in pearl millet-wheat cropping system on sandy loam soils of Haryana (India). The use of organic manures along with fertilizers and bio-fertilizers resulted in improved nutrient status of soil enhancing both micro and macro nutrient pools in soil. The combination of fertilizers with organic manures reduced the soil pH up to greater extent over sole application of inorganic fertilizers under salt stress conditions. The INM reduced the bulk density, increased the water holding capacity and improved the overall soil health. This resulted in increased transformation of micro and macro nutrients in soil, thus enhancing their uptake by plants giving higher crop production.
