Economic evaluation of conservation tillage options for deciding the feasibility of their adoption

The present experiment was conducted to evaluate two important conservation tillage practices namely zero tillage in wheat and bed planting for growing vegetables for deciding the economic feasibility of their adoption in Gohana and Kharkhoda block of Sonipat district in Haryana. In first scenario, comparison were made between Puddled transplanted rice followed by conventional tilled wheat (PTR – CTW), and puddled transplanted rice followed by zero till wheat (PTR – ZTW). In second scenario, conventionally tilled Jowar in kharif followed by conventionally tilled wheat system (CTJ – CTW) was compared with vegetables on beds in both seasons (BV-BV). Sowing of wheat by zero till drill in PTR – ZTW system, decreased cost of cultivation by 21% over its value of Rs 20688 in PTR – CTW treatment; increased grain yield by 5% over the grain yield of 5.99 t ha-1 in PTR – CTW treatment. The B: C ratio of PTR – ZTW was 4.65 while that of PTR – CTW treatment was 3.24, which indicated economic viability of zero tillage practice. While in case of cauliflower in BV-BV system, the total cost of cultivation was estimated at Rs 51500/ha and net returns of Rs 38072/ha i.e an increased net return of 5.8 times over the net return of Rs 46223.5 in CTJ – CTW treatment. The B: C ratio of BV-BV was 5.21, while that of CTJ – CTW treatment was 2.35. Thus, it was concluded that in rabi season, cauliflower on beds and zero till wheat are most economically viable options in this temporary waterlogged regions of Yamuna basin

Adult Education for a Civil Society: Starting Over

To start over adult educators need to reexamine the present practice of adult education and community development in Canada, as compared to our earlier ideals for the field that included the promotion of greater democracy, social equality and equitable economic opportunities for all Canadians. In this reassessment, we need to consider the broader potential of our community agencies, as sites for revitalizing our civil society

Medication adherence and its determinants amongst anti-hypertensive patients in a tertiary care hospital in Navi Mumbai

Background: Anti-hypertensive drugs can effectively control hypertension, subject to good adherence. Uncontrolled hypertension can lead to numerous complications, some even potentially fatal, such as myocardial infarction, atherosclerosis, thromboembolism, shock and stroke.Methods: A cross-sectional prospective study was conducted with the help of a pre-validated questionnaire during the course of 6 months in the medicine outpatient department and the inpatient department (wards) at a tertiary care hospital, Navi Mumbai in 200 hypertensive patients to calculate the correlation of the sociodemographic factors with adherence by the chi-squared test.Results: The overall percentage of adherence to antihypertensive medication was 34.8%. It was the highest (72.1%) in the younger age group, i.e., below 50 years. It was observed that as the age increases, the adherence to treatment decreases. Adherence rates were significantly higher among females and those individuals who had never attended school. Among the employed, 70.3% were adherent to their treatment and among the unemployed, 64.4% were adherent. The percentage of adherence was lower in alcohol consumers (9.5%) as compared to nonusers (76% and 32%, respectively).Conclusions: The clinician advising anti-hypertensive therapy should provide thorough counselling and stress on the issues created due to poor medication adherence as hypertension can be associated with severe outcomes. Treatments should be given in accordance with each patient’s lifestyles in mind such that they may continue taking their medications till the completion of their therapy

Assessment of soil physical health and productivity of Kharkhoda and Gohana blocks of Sonipat district (Haryana), India

In order to assess soil health of Kharkhoda and Gohana blocks of Sonipat district (a part of western Yamuna canal irrigated region), important parameters namely pH, electrical conductivity (EC), texture, bulk density (BD), saturated hydraulic conductivity (HC), soil organic carbon (OC), available water retension capacity (AWRC) and non capillary pores (NCP) were measured by collecting undisturbed soil samples in nearly 66 villages. Soil physical rating index (PI) method was used to compute PI which was an indicator of soil physical health of thatregion. Results revealed that in Gohana and Kharkhoda blocks, nearly 90% area had pH <8.0 and EC>4 dS m-1, which indicated that soils were saline. Prediction maps of soil BD showed that 75% of the total area in 15-30 cm soil layer had BD above >1.6 mg m-3, which indicated the presence of hard pan in subsurface. HC data of subsurface layer also showed that 60% of the area had values<0.5 cm hr-1 which reconfirmed the presence of hard pan. For both surface as well as subsurface soil layers, mostly AWC was >10% which indicated adequate water retention capacity of these soils. However 85% of subsurface had poor soil aeration capacity as indicated NCP range < 10 %. Prediction map of PI for subsurface layer showed that majority of area had PI<0.4 which indicated that expected yield of the crop cannot be more than 70% of the potential yield even under normal or higher levels of fertilizer and water inputs

Bio-physical and physiological changes associated with seed enhancement treatments in speciality maize (Zea mays)

Efficacy of seed enhancement treatments were evaluated on four maize (Zea mays L.) varieties; HQPM-1, VL Amber pop corn, Win orange sweet corn and Navjot. Seeds were subjected to hydropriming (17 h/20°C), halo priming (KNO3: 0.3%/17 h/ 20°C) and magneto priming (1000G/2h) and changes in emergence percentage, its speed, seedling vigour, seedling root growth, seed absorption-desorption patterns and water activity were studied. Seed enhancement treatments significantly increased seedling emergence (23.9-27.7%); speed of emergence (31.1-39.6%); seedling vigour (33.5- 44.5%) and root growth with respect to total surface area, length and volume. These treatments also modified water absorption and desorption patterns of the seed and increased seed water activity compared to control. The most effective treatment was magneto priming, followed by halo and hydro priming. Quality protein maize HQPM 1 showed highest enhancement in different traits among genotypes compared in the study

Modelling soil water balance and root water uptake in cotton grown under different soil conservation practices in the Indo-Gangetic Plain

Although soil conservation practices are being promoted as better environmental protection technologies than traditional farmers’ practice, limited information is available on how these practices affect soil water balance and root water uptake. The root water uptake (RWU) patterns of cotton grown under soil conservation practices and soil water balance in cotton (Gossypium hirsutum L.) fieldsunder a cotton-wheat (Triticum aestivum L.) cropping system were analyzed using the Hydrus-2D model. The treatments were: conventional tillage (CT), zero tillage (ZT), permanent narrow beds (PNB), permanent broad beds (PBB), ZT with residue (ZT+R), PNB with residue (PNB+R) and PBB with residue (PBB+R). Results in the third year of the cotton crop indicated that the surface (0–15cm layer) field saturated hydraulic conductivity in both PNB and PBB plots were similar and were significantly higher than in the ZT plots. Computed potential transpiration rates (Trp) under CT were lower than in other treatments, due to less radiation interception and lower Leaf Area Index (LAI). Both PNB and PBB plots had higher Trp and crop yields than CT plots, which were further improved by residue retention. Predicted soil water content (SWC) patterns during the simulation periods of third and fourth years showed strong correlation (R2=0.88, n=105, P<0.001, the root mean square error (RMSE)=0.025, and the average relative error (AVE)=7.5% for the third year and R2=0.81, n=105, P<0.001, RMSE=0.021, and AVE=9% for the fourth year) with the actual field measured SWCs. Cumulative RWU (mm) were in the order: ZT (143

Not AvailableA field study was conducted in alluvial sandy loam soil to assess the impact of amendments and hydrogel application on soil hydrophysical properties. Soil physical environment was characterized and quantified using soil physical quality index (S). The main treatments include farmyard manure (FYM) and tank soil applied at 5 t ha−1 and no amendment, and subtreatments included three rates of hydrogel: 5, 2.5, and 0 kg ha−1. Hydrogel was applied at 5–7 cm deep just below the seed in rows. Results revealed that FYM along with gel application at 5 kg ha−1 significantly increased mean weight diameter, field capacity moisture content, plant-available water content and relative field capacity, retention pores (Ret P), water-stable structural units, and structural coefficient and reduced transmission pores (TP), penetration resistance, and saturated hydraulic conductivity (Ks). Significantly greater values of S in hydrogel-treated plots and close associations of S with other soil physical parameters were obtainedICAR-IAR
