Cymbopogan martini var. Motia commonly known as Palmarosa or Rosha grass is a tall perennial tufted hedge native of most parts of sub-tropical India. Palmarosa oil has a sweet floral rose-like odour also has notes of rye bread, tea and clary sage. The oil is extensively used as perfumery raw material in soaps; floral rose-like perfumes; cosmetics preparations and in the manufacture of mosquito repellent products. It is used for flavoring tobacco products, foods and non-alcoholic beverages. The volatile oil is used as a remedy for lumbago, stiff joints, skin diseases and for bilious complaints .Considering the importance of this crop every efforts are being made to increase the oil production of the crop by using improved nutrient management practices.

<p>Soil health is dependent upon complex bio-physical and bio-chemical processes which interact in space and time. Microrganisms and fauna in soil comprise highly diverse and dynamic communities that contribute, over either short or long time frames, to the transformation of geological minerals and release of essential nutrients for plant growth. Certified organic soil management practices generally restrict the use of chemically-processed highly soluble plant nutrients, leading to dependence on nutrient sources that require microbial transformation of poorly soluble geological minerals. Consequently, slow release of nutrients controls their rate of uptake by plants and associated plant physiological processes. Microbial and faunal interactions influence soil structure at various scales, within and between crystalline mineral grains, creating complex soil pore networks that further influence soil function, including the nutrient release and uptake by roots. The incorporation of organic matter into soil, as either manure or compost in organic farming systems is controlled to avoid excessive release of soluble nutrients such as nitrogen and phosphorus, while simultaneously contributing an essential source of carbon for growth and activity of soil organisms. The interdependence of many soil physical and chemical processes contributing to soil health is strongly linked to activities of the organisms living in soil as well as to root structure and function. Capitalizing on these contributions to soil health cannot be achieved without holistic, multiscale approaches to nutrient management, an understanding of interactions between carbon pools, mineral complexes and soil mineralogy, and detailed examination of farm nutrient budgets.</p>

The use of new methods describing the “readily available” nutrient content of the soil is spreading on a global scale. The 0.01 M CaCl2 extractant is a dilute salt solution in which the easily soluble inorganic (nitrate-N and ammonium-N) and organic N fractions, P, K and micronutrients are also measurable. The 0.01 M CaCl2 has been tested in the University of Debrecen, Institute of Agricultural Chemistry and Soil Sciences since the 90’s. The results of the researches related to organic N fraction, performed in the last decades, and the results of the present study (originating from the long-term experiment of Karcag, 2007–2009) can be concluded as follows: The measurement of easily soluble and oxidizable organic nitrogen (Norg), besides inorganic fractions, could improve the nutrient management. The amount of the Norg fraction is determined by the soil conditions, therefore it is considered to be a site-specific parameter. Management practices and cropyear affect the amount of Norg as well. The present research confirmed that, the effect of fertilization on the amount of Norg can be explained by the changing of the yield (related to total biomass production), while the effect of cropyear is related to the differences in mineralization circumstances and yield as well. The measurement of the Norg fraction is increases the accuracy of N-supply, therefore it could prevent the environmentally harmful excess N application as well.

Nutrient loss from commercial vegetable fields has become a significant environmental issue in all the major vegetable-producing regions of the United States. Growers are facing potentially disruptive regulations aimed at improving the quality of both surface and ground water. Significant improvement in nutrient management will be required to meet this regulatory challenge. This paper discusses five practical, low-cost nutrient best management practices (BMPs). These BMPs are widely applicable, relatively inexpensive to implement, and can dramatically reduce nitrogen and phosphorus loss from vegetable fields. However, even with careful application of these BMPs, runoff and leachate from vegetable fields may periodically exceed environmental water quality standards, which are very stringent.

Binucleate Rhizoctonia (BNR) fungi are essential for the germination of vanilla seeds. Chemical control of the soil-borne pathogen might adversely affect BNR. The purpose of this study is to determine the effect of Nicotiana tabacum extract biopesticides and Fusarium oxysporum f.sp. vanillae (Fusarium) on vanilla plant nutrient content induced by BNR. Materials and Methods. The research design was completely randomized design with two factors and three replications. The first factor was biopesticide (dosage of 0, 10, 20, and 30 ml/seedling), and the second factor was the application of Fusarium. Results. The increase in the nitrogen, phosphorus, and potassium content of vanilla was affected by biopesticides and Fusarium inoculation. Fusarium inoculation has no significant effect on nitrogen and phosphorus levels but significantly affects potassium levels. The biopesticide dosage is significant for nitrogen, phosphorus, and potassium. The interaction of biopesticides with Fusarium inoculation did not significantly affect the parameters of nitrogen and phosphorus content, but significantly affected potassium content. Conclusion. The application of biopesticides and Fusarium inoculation after induction of BNR can increase nitrogen, phosphorus, and potassium content of vanilla plants.

The field experiments were conducted during kharif2013, 2014 and 2015 at Research Farm of Zonal Agricultural Research Station, Jhabua to study the effect of nutrient management practices on yields, nutrient content and economics of the soybean grown under rainfed condition of Jhabuahill. The experiment laid out in randomized block design with nine nutrient levels viz., T1-control, T2- vermicompost (5t/ha), T3-FYM (10 t/ha), T4-Recommended dose of fertilizers (RDF=20 N: 30 P2O5: 20 K2O kg/ha), T5-50% RDF + Rhizobium + PSB, T6- 50% RDF + 50% vermicompost, T7-50% RDF + 25% vermicompost + Rhizobium + PSB, T8- Rhizobium culture + PSB and T9- 50% vermicompost + Rhizobium + PSB. Results revealed that application of application of 50% RDF + 50% vermicompost(T6) gave significantly highest seed yield (22.62 q/ha), straw yield (23.86 q/ha), biological yield (46.48), gross return (Rs. 69,230/ha), net return (Rs. 49,571/ha), production efficiency (20.56 kg/ha/day) and economic efficiency (450.64 Rs./ha/day) as compared to control. Whereas maximum B:C ratio (3.84) was recorded in 100% RDF followed by vermicompost @ 5 t/ha. Similarly, higher nutrient content (N, P and K) in seed as well as straw and their uptake were recorded under 50% RDF + 50% vermicompost. The highest protein content (41.99%) and protein yield (94,864 kg/ha) was also observed with the application of 50% RDF + 50% vermicompost. Hence, application of 50% RDF + 50% vermicompost better for obtain higher yields, economics and nutrient content and their uptake of soybean under rainfed condition of Jhabuahill of Madhya Pradesh

Soil Fertility Status

Mapping the spatial distribution of soil fertility in a particular area gives an idea about the nutrient content in the soil which plays an im-portant role in fertilizer recommendation, sustainable soil manage-ment, integrated plant nutrient management, landuse planning, and site-specific nutrient management (SSNM). A study was carried out to assess the soil fertility status of the Rapti Municipality, Chitwan, Ne-pal. A total of 120 soil samples was collected based on land use, slope, and aspects with the useof Google Earth Pro (GEP) and ArcGIS. Based on the soil test report spatial variation of soil texture, soil pH, total nitrogen, available phosphorous, and potassium of the study area was prepared. The majority of the study area (57.11%) has sandy clay soils. The soil pH was very strongly acidic to slightly alkaline with pH values ranging from 4.8 to 8.0. Soil organic matter (1.94-3.75%), total nitrogen (0.097-0.187%), available phosphorous(51.03-270.10 kgha-1), and available potassium (169.87-358.68 kgha-1) in the soil are within the range of medium to high in the study area. To maintain this nutrient status, the use of organic manure, reduced use of chemical fertilizers, and different soil management practices should be adopted in this area.
