NITROGEN AND PHOSPHORUS REMOVAL WITH SURFACE RUNOFF FROM DIFFERENT LAND USES- A STUDY IN A SUB CATCHMENT OF UPPER MAHAWELI CATCHMENT AREA IN SRI LANKA
Get PDFCatchment of the river Mahaweli is the largest watershed in Sri Lanka. There arefour major reservoirs built across river Mahaweli to generate hydropower and to irrigateagricultural lands in dry zone of the country. However, siltation and water qualitydeterioration of reservoirs are major issues when considering their sustainability. Mainagricultural land uses in the Upper Mahaweli Catchment Area (UMCA) are tea plantationsand vegetable farming on terraces in hilly slopes. Most of these terraces are not properlymanaged hence highly vulnerable to soil erosion. Hence, this study was conducted to measuresurface runoff and removal of sediments and plant nutrients from vegetable plots in wellmanaged Terraces (WMT) and Poorly Managed Terraces (PMT), Tea Plantations (TP) andForest Gardens (FG) in a sub catchment of UMCA. Runoff plots were established to measuresurface runoff and sediment loads in different land uses. Water soluble and sediment attachednutrient fractions were quantified. Soil chemical parameters of different land uses were alsoassessed using standard methods. A linear relationship between rainfall and surface runoffwere observed in all tested land uses. The sediment transport rate was higher in vegetable plotson poorly managed terraces followed by well managed vegetable plots, tea land and naturalforest. Nutrient removal with surface runoff was higher in vegetable plots compared to otherland uses. A greater fraction of NO3-N was removed as soluble form from farmlands but inthe case of PO4-P and NH4-N removal of particulate fraction was prominent. Particulatelosses were approximately 15 times higher than the dissolved losses for NH4-N andapproximately 100 times higher than the dissolved losses for PO4-P. In the case of NO3-N,soluble fraction was approximately 1.5 times higher than the particulate losses. Resultsconclude that, greater amount of nutrients and sediments are transported from vegetable plotson poorly managed terraces. Hence, proper maintenance of vegetable growing terracescoupled with effective nutrient management is very important to reduce downstream siltationand nutrient pollution in surface waters. 
Efficacy of Bioagents and Fungicides against Sclerotium rolfsii of Tuberose
Get PDFTuberose (Polianthes tuberose L.) is one of the important ornamental crops being cultivatedmainly for its cut and loose flower and oil trade in the tropical and subtropical regions ofIndia. Tuberose is reported to be affected by many diseases of which stem rot caused bySclerotium rolfsii is the most important one in the tuberose growing regions of Tamil Nadu.The commercial cultivation of tuberose has been hampered due to the occurrence of root rot(Das, 1961). Little work has been done on the management of diseases of tuberose. Hence, itis necessary to evaluate bioagents and fungicides in vitro condition to formulate managementstrategy against root rot of tuberose.

Get PDFThe present study entitled “Adoption Behaviour of okra growers in Arajiline block ofVaranasi district in Uttar Pradesh.” was carried out during the year 2018-19 in 20 selected villagesof Arajiline blocks of Varanasi district of Uttar Pradesh state. A total of 120 respondents wereselected and interviewed randomly from a list of Okra growers to collect the primary data on thebasis of objectives and variables of the study. Further, the data was tabulated and analysedstatistically to draw appropriate conclusions. It was found that most of the okra growers hadmarginal size of land holding (less than 1 ha) and were involved in agriculture (okra cultivation) asthe principal occupation with an annual income between Rs. 30,000 to Rs.50,000. Majority of therespondents had medium level of exposure to various sources of information for acquiring theinformation about okra production technology amongst the information sources. However, overalllow level of contact with extension personnel were observed among the respondents. The findingsof the study revealed that the majority of the okra growers had medium level of knowledgeregarding recommended okra production technology. In respect of the correlation analysis, thevariables land holding, organizational participation and annual income were found to have nonsignificant relationship with adoption at 0.005 per cent level of significance. However, the variableseducation, size of family, social participation, annual income, knowledge, source of informationand extension contact were found to be significant in correlation with adoption behavior
EXTENT OF ADOPTION OF RECOMMENDED FERTILIZER MANAGEMENT UNDER SOIL HEALTH CARD SCHEME IN BALDIRAI BLOCK OF SULTANPUR DISTRICT
Get PDFInjudicious and haphazard use of chemical fertilizer in agriculture is amatter of concern in recent times. To avoid deterioration of soil in long run and visualizingthe importance of balance nutrient in crop production. The soil health card (SHC) providessoil health data to get appropriate guidance to the farmers for the efficient use of fertilizerto cultivate crops based on soil health analysis. The SHC is a simple document, whichcontains useful data on soil based on chemical analysis of the soil to describe soil health interms of its nutrient availability and its physical and chemical properties. The soil healthcard is made available online also for the farmers. To understand the feelings of thefarmers against this system, there is an urgent need to study the degree of positive ornegative disposition associated with farmer towards the usefulness and application of soilhealth card. Thus the present study on farmers’ perception regarding soil health card wasundertaken. The study was conducted in Sultanpur district with 120 soil health cardholders. The findings revealed that majority of the farmers were having knowledge andunderstanding about the utility of soil health card. The findings further reveals thatmaximum number of soil health card holders were having favorable attitude towards soilhealth card followed by less favorable and most favorable attitude towards soil health card.Among constraints, received soil health card after crop harvest was the major constraintfaced by majority of the respondents.
