Identification and Planning of Water Quality Monitoring Network in Context of Integrated Water Resource Management (IWRM)

Hydrological system is a quite complex and dynamic in nature because of the heterogeneity of the earth crust and surrounding atmosphere. Water exists on the earth in all three forms of liquid, solid and gas. The scarcity of its liquid freshwater has resulted because of increasing demand in response to growing population, contamination and pollution of freshwater bodies due to urbanization and industrialization. Precise measurement of water quality, in present time, has become the necessity because of increasing scarcity of this precious resource. In a global perspective, organizations dealing with water supply and monitoring are ever concerned about precise assessment of water quality. Researchers are focusing on the assessment of surface and ground water quality on spatial scale rather than point scale, which needs strengthening of monitoring networks time-to-time. The design of a hydrometric network starts ideally with a minimum number of stations, and increases gradually until an optimum network is attained when the amount and quality of data collected and information processed is economically justifiable and it meets the user’s needs to make specific decisions. In hydrology, monitoring of data is mostly site-specific and proper representation of this data on spatial scale requires proper network planning. Since the drivers of water quality vary in space and time, the quality of water also varies in space and time. It is therefore imperative to monitor the quality of water under heterogeneous space-dependent conditions for which a specialized water quality monitoring network is essential. The present paper is in the context of identifying and planning of water quality monitoring network for data acquisition for Integrated Water Resources Management (IWRM).

Assessment and Characterization of Soil of Pandariya Block in Kabeerdham District, Chhattisgarh, India

Soil is the basic resource for agriculture and its proper management is essential to sustain agricultural production and maintain soil productivity. Soil testing is one of the best available tools, to ascertain the physical characteristics & nutrient status of a field so as to assess the fertilizer requirements for a crop or a cropping system or for knowing the reclamation requirements if the soil is saline or sodic in nature. Fertilizer application based on soil tests is the best available approach for harvesting the economically viable potential yields of crops by increasing input use efficiency and maintaining soil health (Singh and Brar, 2005). Soil test-based fertility management is an effective tool for increasing productivity of agricultural soils that have high degree of spatial variability resulting from the combined effects of physical, chemical or biological processes (Goovaerts, 1998). The production of rice crop is more in the Central part of India. Chhattisgarh is situated in the central part of India. The state of Chhattisgarh, with Raipur as its capital, came into existence on 1st November, 2000 by separation of 16 districts of Chhattisgarh region from Madhya Pradesh. At present 27 districts are there in Chhattisgarh.

Effect of Different Levels of NPK and Vermicompost on Physico-Chemical Properties of Soil, Growth and Yield of Okra [Abelmoschus esculentus L.] var. Rohini

Okra is one of the most important vegetable crop grown in tropical and sub-tropical region and is said to be native of South Africa and Asia. In India, it is cultivated almost in all states throughout the year and consumed by bulk of the people. Major okra growing states in India are Uttar Pradesh, Bihar and Orissa. The total area under okra crop in India is about 533’000 ha with production of 6346’000 metric tonnes with productivity 11.90 metric tonnes. In Maharashtra it is grown on an area about 23,000 ha with production of 242’000 metric tonnes with productivity 10.500 metric tonnes in year 2013-14 (Anonymous, 2014).

Response of Integrated Nutrient Management on Soil Properties, Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) Cv. Pusa Sadabahar

Cluster bean [Cyamopsis tetragonoloba (L.) Taub] popularly known as “Guar” is an important legume crop mainly grown under rainfed condition in arid and semi-regions of Rajasthan during kharif season. It is very hardy and drought tolerant crop. Its deep penetrating roots enable the plant to utilize available moisture more efficiently and thus offer better scope for rainfed cropping. The crop also survives even at moderate salinity and alkalinity conditions. There is no other legume crop so hardy and drought tolerant as cluster bean (Kherawat et al., 2013).
