Effect of irrigation scheduling and nitrogen levels on growth, yield and water productivity of linseed (Linum usitatissimum L.) under Vertisols

A field experiment was conducted during Rabi season of 2015-16 at the Instructional cum Research Farm, IGKV, Raipur to study the effect of different irrigation scheduling and nitrogen levels on growth, yield attributes, yield, water and nitrogen productivity of linseed (Linum usitatissimumL.). The experiment was laid out in split plot design keeping four irrigation schedules viz., come-up (I1), one (I2), two (I3) and three irrigation (I4) in main plots and four levels of nitrogen viz., control (N0), 30 kg (N1), 60 kg (N2) and 90 kg N ha-1 (N3) in sub plots with three replications. Results revealed that highest seed yield was obtained with linseed provided two irrigations (1683 kg ha-1) and application of 90 kg N ha-1 (1604 kg ha-1). Moreover, crop supplied with two irrigations in combination with 90 kg N ha-1 (I3×N3) gave significantly (P=0.05) highest seed yield (2097 kg ha-1) compared to rest of the treatment combinations. The excessive use of irrigation and fertilizers also affects farmer’s economy, as the crop is relatively low yielder. Two irrigations are better than three irrigations in terms of seed yield and water productivity; and application of 60 kg N is better than 90 kg N ha-1 in view of nitrogen productivity. The WP and IWP were decreasing as increasing the number of irrigation, but increasing with increasing the levels of nitrogen, while NP was highest with two irrigations (11.09 kg, kg-1 N) and application of 60 kg N ha-1 (8.90 kg, kg-1 N)

Prevalence And Incidence Of Poliomyelitis In Children In Jaipur City

A random sample in Jaipur city during the period July to October 1986 of 3791 families with a total population of 23, 227 having 2863 children between 5 and 9 years of age, belonging to various castes and communities, comprised the material for the present study. The prevalence of poliomyelitis was found to be 6.98/1000 children 5-9 years of age and the incidence was 2.32 /1000 children 0-5 years of age. Most of the cases (85%) were lame due to poliomyelitis by 2 years of age and mean age of onset of paralysis was 15.6 months. The right lower limb was more commonly affected. 25% of the lame children had received one or more doses of oral polio vaccine, 25% developed provocative paralysis following injection. 75% of the lame children had 2nd or 3rd degree of disability

Not AvailableThe present investigation was carried out to evaluate the changes in oxidizable soil organic carbon (SOC), hydraulic properties and yield of both maize (Zea mays) and wheat (Triticum aestivum) under long–term fertilization during 34th cropping cycle. Six fertilizer treatments were selected for the present study. The soil samples were analyzed for oxidizable SOC, bulk density (BD), mean weight diameter (MWD), soil water retention at 33 and 1500 kPa, saturated hydraulic conductivity (Ksat) at surface (0-15 cm) and sub– surface (15–30 cm) soil layers. The plant samples were analyzed for nutrient uptake at harvest. The results showed that N and NP fertilizer treatments maintained initial oxidizable SOC and soil physical condition in surface layer, and showed significantly higher values compared with control. However, significant reductions in yield and nutrient uptake by maize and wheat were observed in these treatments compared to nitrogen, phosphorus and potassium (NPK) applied plot, nitrogen, phosphorus, potassium and sulphur (NPKS) applied plot and NPK+ farmyard manure (FYM) treatment. The NPK + FYM application significantly increased oxidizable SOC, MWD and decreased BD compared to control plots and the initial values. Balanced application of plant nutrients through mineral fertilizers and FYM increased oxidizable SOC by 84 per cent and improved soil hydraulic properties, uptake and yield of both maize and wheat compared to control. Integrated use of NPK along with FYM was the best option for sustaining soil physical condition, enhancing nutrient uptake and ultimately crop productivity.Not Availabl

Synthetic and organic mulching and nitrogen effect on winter wheat (Triticum aestivum L.) in a semi-arid environment

Field experiments were conducted in 2002-2003 and 2003-2004 to evaluate the relative performance of synthetic (black polyethylene) and organic (paddy husk and straw) mulches on soil and plant water status vis-a-vis N uptake in wheat in a semi-arid environment of India. Scope of better utilization of soil moisture was documented through all the mulches, especially during initial crop growth stages, when the moisture content was 1-3% higher in mulches. Soil temperature was more moderate under organic mulches. Paddy husk recorded significantly higher plant biomass, while the effect of mulching in enhancing root growth was clearly documented. Organic mulches produced more roots (25 and 40% higher root weight and root length densities compared to no-mulch) in sub-surface (>0.15m) layers, probably due to greater retention of soil moisture in deeper layers and relatively narrow range of soil temperature changes under these systems. Incremental N dose significantly improved all the plant parameters in both mulch and no-mulch treatments. Grain yield was 13-21% higher under mulch and so with increasing N levels. Nitrogen uptake was higher in organic mulches and also with higher N doses, while polyethylene mulch showed mixed trend. Mulches were effective in reducing 3-11% crop water use and improved its efficiency by 25%. Grain yield and biomass were well-correlated with leaf area index (r=0.87 and 0.91, respectively) and water use was better correlated with root length than its weight. Results indicated substantial improvement in water and N use efficiency and crop growth in wheat under surface mulching, and the organic mulches, especially rice husk performed better than synthetic mulches.Organic and synthetic mulch Crop growth N uptake Water use Wheat
