No full textAbstract The morphometric parameters are depicting the hydrological reaction through geographic information systems (GIS) and geospatial techniques used for water conservation. In this area, drainage system shows a dendritic pattern occasion where the most outrageous number of streams found in the primary request and the stream arrange extended by receding in stream number. The preference criteria were chosen in the pappiredipatti watershed compared to other watersheds in the sub basin based on slope condition, rainfall, and weathered zone thickness. The highest mean bifurcation ratio is 4.9 at yercaud watershed whereas the lowest mean bifurcation ration is 1.8 in kadattur watersheds. The mean bifurcation proportion was 3.125 which demonstrate that the discharge design is influenced by auxiliary aggravations. The Elongation ratio lowest in 0.53 at kadattur and highest at KRW is 0.8, form factor esteems were 0.67 and 0.1.92 which specify stretched state of the bowl having a compliment high point of the stream for longer spans. Flowing streams of the prolonged basin are less demanding to oversee for accommodating to deciding the impact of the catchment territory on hydrological valuation. In the pappiredipatti watershed was chosen preference criteria of recharge structures, number of structures 8, 12, and 30 of check dams were built on 1st, 2nd, 3rd order stream individually. Two permeation lakes were developed nearer to 3rd order stream. Artificial recharge structures in 1st order are lower than in 2nd order, according to the morphometric investigation, the 2nd and 3rd order stream are described by high penetrable, high infiltration limit and low help, which is conducive for the recharge. The accompanying observations made while settling on the sort and plan of maintainability structures for the proper location

<i>In vitro </i>multiplication of <i>Nothapodites foetida </i>(Wight.) Sleumer through seedling explant cultures
No full text273-277In vitro multiplication of Nothapodites
foetida (Wight.) Sleumer was achieved using axenic seedling explant cultures.
Isolated nodes (1.0-1.2 cm) and shoot tips (1.0-1.5 cm) cultured in Murashige and
Skoog's agar medium containing varying concentrations of TDZ, BA and combinations
of 2iP and GA3. Single shoot (0.8-1.2 cm) was regenerated in each culture
after 6 weeks. Axillary shoots were then excised
and recultured for 8 weeks in medium containing TDZ (0.05 mgL-1) which
formed shoots (about 4 in no.; 2 cm) from the basal node. Axillary branches (2)
which formed on 60% of these shoots after 10-12 weeks of culture were separated
and recultured in the same medium for 8 weeks. Three shoots (0.8-1.0 cm) per culture
were regenerated. Shoots of 0.8-1.8 cm length were subcultured on a low cytokinin
(0.01 mgL-1 TDZ) regime to induce shoot elongation (2.0-3.5 cm) in 4
weeks. Shoot cuttings were rooted (60%) in the medium containing IBA (1.5 mgL-1).
Rooted plantlets established in pots (90%) after hardening resumed normal growth
in 3 months
Assessment of groundwater quality for drinking and irrigation purposes in arid areas of Rajasthan, India
No full textAbstract The quality of groundwater is poorly understood in the arid northwest part of Rajasthan, whereas it is the only source of drinking and irrigation and the residents consume it without any prior treatment. This study illustrates the qualitative analysis of groundwater and its suitability in the bulk samples collected from three different canal catchment areas. Most of the samples were identified for higher values of EC, TDS, TH and fluoride, therefore considered posing restriction to drinking use. The abundance of major ions was found in the order of Na+ > Ca+2 > Mg+2 > K+ = Cl− > HCO3− > SO4−2 > NO3− > F−. The irrigation quality parameters such as sodium adsorption ratio, %Na, residual sodium carbonate, residual sodium bicarbonate, Kelley’s index, potential salinity, magnesium hazard, Mg/Ca ratio and permeability index were calculated and discussed thoroughly in combination with Wilcox, USSL and Doneen diagrams. Most of the samples belong to predominant Cl− and Na+ in hydrogeochemical studies. According to USSL diagram, majority of the samples fall under C4S1 class. Furthermore, groundwater chemistry was found mainly influenced by evaporation–crystallization in Gibbs variation diagram. This study suggested that groundwater is unsafe for drinking purpose without purification and quality measures should be considered while cropping in its irrigation use
