Water under the maximum rainfall

Leaching behaviour of combination product (novaluron 5.25% + indoxacarb 4.5% SC) was investigated in sandy loam soil at 43.31 + 37.13 g a.i. ha-1 (single dose) and 86.62 + 74.26 g a.i. ha-1 (double dose) under laboratory conditions as per average annual rainfall of 400 mm. Residues of novaluron and indoxacarb were estimated at different depths of soil and in leachates with the help of gas liquid chromatography (GLC) equipped with electron capture detector (ECD). Method was validated by performing recovery experiments at different spiking (0.01 - 0.10 mg kg-1 ) levels.

A wheat growth model that includes the direct responses of canopy photosynthesis and transpiration to elevated CO2, and the response of crop growth to water stress has been developed and tested. Sensitivity analyses show that different cultivars have quite different responses to changes in ambient air temperature, ambient CO2 concentration and rainfall. Because crops reach maturity earlier under higher temperature, an increase of 3 oC may not impose further water stress to growth of a wheat crop.

Recharge basin structure having masonry spillway was evaluated in the experiment. The quantities of available runoff water under the maximum rainfall up to 5 consecutive days were estimated. Hydrograph was prepared by recording water level in the basin against time for duration of live storage period.

Uneven distribution pattern of monsoon rain and highly permeable soil type and poor rainwater management practices effect the crop yield. Also lands remain barren in winter season due to lack of rainfall. A Dynamic Programing (DP) model is developed to allocate optimum supplemental irrigation to crop for receives maximum net annual return from the cropped area under land and water availability constraints in the OFR based rainfed agricultural system.

The study mainly focused on the water harvesting structures adopted by farmers in dry land areas of Tamil Nadu. The study was conducted in four districts of Tamil Nadu such as Virudhunagar, Ramanathapuram, Sivagangai and Madurai based on the maximum area under dry lands condition. In these locale, the villages were selected by appraisal of several indicators namely rainfall, climate conditions, livelihood analysis and overall agriculture development. Participatory Rural Appraisal methodology was adopted to identify and gather information about the water harvesting practices for water saving.

Coconut has a prolonged reproductive phase of 44 months from the initiation of the inflorescence primordium to full maturity of the nuts. Weather affects all stages of the long development cycle and thus there is likely to be extended predictability based on climate variability. An attempt is being made to relate the coconut sample survey data of Coconut Development Board with climate data of Chanrayapatna taluk of Hassan district. Mean nut yield per palm, per year in the Chanrayapatna taluk was 83.3. Among the villages, Baldare recorded significantly lower nut yield (78.

Rainfall is a prime input for various engineering design such as hydraulic structures, water conservation structures, bridges and culverts, canals, storm water sewer and road drainage system. The detailed statistical analysis of each region is essential to estimate the relevant input value for design and analysis of engineering structures and also for crop planning. The present study comprises statistical analysis i.e. frequency analysis of daily maximum rainfall data of Udaipur district.
