“…Chromolaena odorata is also suggested as a beneficial fallow plant rather than a weed due to its richness of organic matter, exchangeable potassium content and better adaptability on acidic soils than some leguminous plants (Koutika & Rainey 2010). Moreover, dried leaf powder of Lantana camara mixed with mycorrhizae was also recorded higher growth and yield of the lentil and red kidney bean in Nepal proving the effectiveness of the application of organic matter on plant growth (Vaidya & Bhattarai 2014).…”

Tithonia diversifolia, Sphagneticola trilobata, Mikania scandens, Lantana camara, Chromolaena odorata, Panicum maximum and Mimosa pigra are common weeds in Sri Lanka. This study was aimed to assess the nutrient release potential and the weight loss dynamics during leaching of the above weeds to utilize them as organic liquid fertilizers. Thirty samples from each species of oven-dried leaves (5 g) were placed separately in 1 L of distilled water. Three samples of each species were randomly collected at 1, 3, 5, 7, 14, 28, 42, 56, 70 and 84 days and the massloss, electrical conductivity (EC), pH and nutrient contents of the leachates were determined. Four fertilizers (FP1; the selected weeds Tithonia diversifolia + Mikania scandens + Chromolaena odorata (W), FP2; (W) + topsoil, FP3; (W) + topsoil + coconut husk ash and FP4; (W) + topsoil + coconut husk ash + fish waste) were formulated and based on the nutrient contents the highest nutrient containing FP3 and FP4 were applied on Basella alba. Mass-loss was higher (p<0.05) for Mikania scandens (97%) followed by Tithonia diversifolia (95.8%) and the lowest for Panicum maximum (63.7%). EC and pH of leachates were increased over the time indicating the highest in Mikania scandens (2139±4.7 µS cm -1 ) and Lantana camara (7.86±0.06) respectively, and the lowest in Panicum maximum (877±7.6 µS cm -1 , 7.40±0.02). Nutrient contents of the leachates of Tithonia diversifolia, Mikania scandens and Chromolaena odorata were higher than those of Panicum maximum. FP4 revealed the highest nutrients and growth performances of shoot height (25.0±0.9 cm), number of leaves (12.0±0.6), leaf area (70.7±1.6 cm 2 ), plant fresh weight (56.1±1.2 g) of Basella alba. The results are suggestive of the potential of utilizing Tithonia diversifolia, Mikania scandens and Chromolaena odorata for the formulation of organic fertilizers which would in turn be a low-cost strategy for effective control of these weeds.

“…The land use practices affect chemical, physical and biological properties of soil [25], however the biological properties of soil are rarely considered for agriculture. Soil in Nepal is deficient in N, P, and K due to shortage of organic matter in the soil [26]. However, farmers who have been using chemical fertilizer in Kathmandu valley and some of the Terai districts have started to experience its adverse effects on soil quality [26].…”

“…Soil in Nepal is deficient in N, P, and K due to shortage of organic matter in the soil [26]. However, farmers who have been using chemical fertilizer in Kathmandu valley and some of the Terai districts have started to experience its adverse effects on soil quality [26]. Therefore, for the mitigation of these effects, farmers started using compost manures, green manures, integration of legumes in the cropping system, use of farm yard manure (FYM), homemade botanical pesticides, among other practices in their agricultural crops.…”

Disturbances can affect the incidence of Arbuscular Mycorrhizal Fungi (AMF) in both agricultural and natural ecosystems. The present study is a first attempt for the qualitative assessment of AMF diversity in adjacent areas of a forest ecosystem with different land uses and assess levels of mycorrhizal colonization by these fungi. A total of five soil samples were taken randomly from each of the following areas situated within the same landscape: undisturbed coniferous forest (UF), degraded forest (DF) and cultivated land (CL). A total of 22 taxa of arbuscular mycorrhizal fungi belonging to eight genera were identified morphologically, Glomus and Acaulospora being the most common. Species richness ranged from 11-14 among land use areas, with 14 species in UF and 11 species in CL. Acaulospora mellea, Gigaspora sp. and two non-identified Glomus species were detected in all areas. While species richness did not differ significantly amongst areas, diversity at the family level was 43% less in CL than in UF. Mean mycorrhizal colonization was higher in DF (28%) than CL (20%). We concluded that land use mainly affected fungal diversity only at the family level and had no impact on mycorrhizal development in sampled roots. This work provides the first step to identify native AMF species in Nepal that might be cultured for further use by small farmers in a sustainable agriculture approach.

“…Due to the high level of soil degradation, practices such as green manuring have started to be used by family farmers in order to overcome soil erosion and improve soil fertility in the region (Coelho et al, 2013). The increase in biodiversity of plants with legumes helps to control erosion, increases nutrient cycling, maintains or increases the quantity and quality of soil organic matter (Vaidya and Bhattarai, 2014;Aguiar et al, 2010) and provides a source of nitrogen (N) for coffee, thus reducing the amount of mineral N that needs to be added to the soil (Coelho et al, 2013;Egodawatta et al, 2012;Matos et al, 2008). Factors such as the choice of green manure species, management of biomass, planting and cutting time, dwelling time of the residues in the soil, and local conditions and their interactions will have an influence on the production of above-ground biomass, the level of nutrient accumulation in the system, and the nutrition of commercial crops (Souza and Guimarães, 2013;Matos et al, 2008;Fontanétti et al, 2006).…”

In mountainous regions, the amount of time that the land is exposed to the sun is one of the factors that influence the productive potential of legumes. The aim of our study was to evaluate, for two different terrain aspects under sun exposure faces, the production of green and dry matter, as well as the nutrient accumulation in the aerial part of legumes and the coffee productivity. The northwestfacing terrain is at 950 m altitude, the average annual temperature is 18.0 °C, the average rainfall is 1320 mm and the average daily solar exposure is 9.1 h. The south-facing terrain is at 690 m altitude, the average annual temperature is 14.0 °C, the average rainfall is 1277 mm and the average daily solar exposure is 6.8 h.The main soil of both terrains are a clayey dystrophic Red-Yellow Oxisol. The experimental design was inrandomized blocks with a 2 x 8 factorial scheme (two different terrain aspects and 8 types of green manure), and four replications were performed.On the northwest-facing terrain, D. lablab, C. spectabilis, and S. deeringianum had the highest amount of dry matter (3.31, 2.98, and 2.85 Mg ha-1 , respectively) and nitrogen accumulation (111.54, 91.83, and 91.51 kg ha-1 , respectively).The most promising legumes on the south-facing terrain (lower altitude, lower temperature, and lower incidence of light) for dry matter productions were C.
