Impact of Natural Farming Practices on Pea (Pisum sativum L.) in Mid-hills of North-Western Himalayas
The study revealed that application of 3 t ha⁻¹ Ghanjeevamrit + 5% Jeevamrit at 15-day intervals (T2) recorded the highest plant height (79.47 cm), plant biomass (21.60 g/plant), protein content (23.69%), and ascorbic acid content (14.13 mg/100 g). This treatment also improved soil properties with maximum nitrogen (329.27 kg ha⁻¹), phosphorus (37.33 kg ha⁻¹), potassium (378.57 kg ha⁻¹), organic carbon (1.46%) and also emerged as the most cost-effective, achieving the highest yield (99.06 q ha⁻¹), net returns (₹1,77,428.7), and a B:C ratio of 1.48, comparable to 100% RDF (T1). The application of 2 t ha⁻¹ Ghanjeevamrit with 10% Jeevamrit at 15-day intervals is recommended as a sustainable alternative to synthetic fertilizers, enhancing crop productivity, soil health and economic viability in pea cultivation, particularly in hill ecosystems.
Assessment of the Impact on Soil Physico-Chemical and Leaf Properties of Drumstick tree (Moringa oleifera L.) in mid hills of North-Western Himalayas
Plants derive essential resources like water, nitrogen (N) and phosphorus, therefore have an enormous effect on changing the physicochemical properties of soil and leaves. In the current study, we have attempted to find out if Moringa oleifera (drumsticks) which are grown under Nahan, forest division of Himachal Pradesh, had any effect on the physico-chemical characteristics of the soil. Three locations were selected from each one of the four blocks and soil samples were collected under the canopy of Moringa oleifera for evaluation of physicochemical properties. Most of the soil is classified as sandy loam to sandy clay loam. Soil pH was found to be neutral. The EC values were also found to be within the safe limits (<0.8 dS m-1). The soil has been categorized as high organic carbon, P, K, Ca, Mg, SO42-, Cu, Fe and Mn. However, N and Zn content was recorded to be within the medium range. The content of leaf N, P, K, S, Fe, Cu and Mn content was in the high range. Moringa leaves contain an adequate amount of chlorophyll and protein content. Soil EC was important and positively associated with soil P, Ca, Mg, Cu and Mn, whereas organic carbon content of soil is important and positively associated with soil total N, total P, total K, total Ca, total Mg and total Mn. A significant correlation between soil and leaf nutrient content revealed that the soil and leaf analysis used in synchronicity exhibits more reliable information on nutritional status depicting trees with good uptake of nutrients. In addition a comprehensive analysis of their chemical composition, nutritional value and antioxidant potential provided strong dietary recommendations, reinforcing their role as a beneficial component of a balanced diet.
Impact of integrated nutrient management on micronutrients uptake in pearl millet-wheat cropping system under saline water irrigation
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.
Assessing the Impact of Microfinance on the Income of Agri-SMEs among Self-Help Group Beneficiaries in Afghanistan and India
Microfinance has grown significantly worldwide, particularly in India and its neighboring regions. This study examines the impact of microfinance on small and medium agricultural enterprises (Agri-SMEs) among beneficiaries of Self-Help Groups (SHGs) in India and Afghanistan. The microfinance programs, launched in both countries to empower Agri-SMEs and enhance the income of SHG members, were analysed in Punjab state, India, and Badakhshan province, Afghanistan. The analysis included both beneficiaries (treatment group) and non-beneficiaries (control group). The study highlights the significant impact of microfinance on the development of SHGs and Agri-SMEs in the selected regions. Using propensity score matching analysis through three methods, Radius Matching, Nearest Neighbor Matching, and Kernel Matching—strong evidence was found supporting the positive influence of SHG participation on the income of agri-SMEs in both countries. The study focuses on microfinance institutions in India, including Punjab National Bank, Fusion Microfinance Pvt. Ltd., Capital Small Finance Bank, and Cooperative Bank, as well as institutions in Afghanistan, such as FMFB, Cooperative Bank, OXUS, and FINCA. Results demonstrate the effectiveness of SHGs in enhancing the income-generating capabilities of small and medium enterprises, regardless of country-specific differences. Moreover, factors such as age, education, and household size were found to have no significant influence on SHG participation, while gender distribution was relatively balanced between participants and non-participants. These findings underscore the potential of SHGs to boost income generation for agri-SMEs and suggest the need for targeted initiatives to promote SHG participation across diverse demographic groups.
Exploring the Allelopathic impact of Wild Pomegranate leaf extracts in field crops establishment and early growth: study from Himalayas
The investigation was conducted in the Agroforestry laboratory of Department of Silviculture and Agroforestry, Dr. Y. S. Parmar university of Horticulture and Forestry Nauni Solan, H.P. in order to assess the allelopathic effect of wild pomegranate leaf extract on the germination and growth development of field crops (maize, mash, chickpea and wheat) along with five concentrations viz., 5%, 10%, 15%, 20% and control (100% distilled water) and four replication in CRD. Results revealed that all the crops were significantly affected by the leaf extract of wild pomegranate. The lowest seed germination (%) as well as growth parameters (radicle length and plumule length) of all the four crops were observed under the application of 20% concentration of leaf extract (T4), while the highest seed germination (%) and growth parameters were obtained under control i.e. 100% distilled water (T5). It was further observed that with increase in the concentration of leaf extract, all the parameters were decreased which shows the inverse relationship between concentration and germination/growth parameters. However, in overall comparison of all the four crops, the maximum germination (92.80 %) and plumule length (10.56 cm) was registered in mash, while, the maximum radicle length (9.14 cm) was recorded in wheat.
