CHARACTERISTICS OF TEXTILE WASTE WATER OF BHILWARA (RAJASTHAN) AND ITS PHOTOCATALYTIC BLEACHING WITH SnO2 CATALYST

During the last decade, Bhilwara has developed into a leading place in the textile industry in India. The water used in textile industry is almost entirely discharged as waste. The effluents are very complex, containing salt, surfactants, ionic metals and their metal complexes, toxic organic chemicals, biocides, and toxic anions, which are harmful to both flora and fauna existing on our planet. Degradation of these non-biodegradable organic compounds is not possible by conventional treatment processes. The analysis of waste water with different quality parameters and photocatalytic bleaching was examined by using UV light in photochemical reactor with SnO2 catalyst

Popularization of improved maize (Zea mays L.) production technology through frontline demonstrations in semi arid zone IVA of Rajasthan

Front line demonstrations (FLD,s) on maize (Zea mays L.) were laid down at 661 farmers’ fields to demonstrate production potential and economic benefits of improved production technologies comprising high yielding varieties namely PM-3, PM-5, PEHM-2, Bio- 9681 and Mahyco 3765 in Rajsamand district of Semi Arid Zone IVa of Rajasthan state during kharif seasons from 2006 to 2012 in rainfed farming situation. The improved production technologies recorded an additional yield ranging from 2.50 to 15.78 qha-1 with a mean of 7.94 qha-1. The per cent increase yield under improved production technologies ranged from 33.17 to 68.16 (PM-3), 14.09 to 59.82 (PM-5), 46.61 to 66.97 (PEHM-2), 55.83 to 92.82 (Bio 9681) and 80.12 (Mahyco 3765) in respective years. The average extension gap, technology gap and technology index were 9.10 qha-1, 5.94 qha-1 and 20.08 per cent, respectively in different varieties of maize. The improved production technologies gave higher benefit cost ratio ranging from 1.28 to 3.00 with a mean of 2.45 compared to local checks (1.10) being grown by farmers under locality. The productivity of maize per unit area could be increased by adopting feasible scientific and sustainable management practices with a suitable variety. Considering the above facts, frontline demonstrations were carried out in a systematic and scientific manner on farmer’s field to show the worth of a new variety and convincing farming community about potentialities of improved production management technologies of maize for further adoption by the farming community

A Study on Impact of Training for Efficient Water Management in Agriculture

Extension functionaries play a catalytic role in adoption of agricultural innovations where water management is no exception. Training plays a pivotal role for enhancing the competence of extension functionaries’ through diffusion of innovations at actual workplace. In this stride, training on scaling up of water productivity in agriculture was organized and evaluated at all the stages of the Knowledge, Attitude, and Skill and Aspiration (KASA) model. The model assumes that change in knowledge, attitude, skill and aspiration leads to modification in practices for creating desired changes in water management in agriculture. Significant change in acquiring knowledge, developing participatory skills, changing attitudes and fulfilling aspirations towards scaling-up of water productivity in agriculture was observed. Hence, the enhanced learning will be effectively diffused among the farmers at the actual workplace for effective water management

Changing behaviour of self help group members: Pathway for sustainable rural livelihoods in Eastern India

The study evaluates the behaviour construct of self help group (SHG) members. Data were solicited from randomly selected 100 SHG members of Patna district, Bihar, India at two point of time (in before and after situation), i e during 2008 and 2013. The behaviour construct developed, consisted of 30 items, for which Cronbach’s alpha coefficient of reliability was observed as 0.82. Data were solicited on three-point continuum, viz. No Change=1, Slightly Changed=2 and Highly Changed=3. The mean values of two situations (before and after situation) were compared (z-statistics) to observe the behavioural change among the SHG members. An improvement of 34.91% between pre (46.09%) and post evaluation (81%) and a significant improvement in behaviour of SHG members was observed, which exemplifies the impact of SHG approach in instilling a positive behavioural orientation. Positive behaviour could play a great role in tackling the issues of rural poverty for improving sustainable livelihood security in eastern India. To achieve this rural livelihoods must assimilate the vital facets like (i) formation and stabilization of SHGs, (ii) pro-poor financial and credit support system, (iii) market-driven and decentralized extension system, (iv) diversification towards high-value enterprises,(v) technological intervention and impact assessment, (vi) media-mix for technology transfer, (vii) frequent educational tour/visits and interaction with other SHGs and research institutes, (viii) developing leadership skills, and (ix) strong political will. Nevertheless, extension system needs to be re-oriented and revitalized with new agricultural knowledge base in emerging technologies and methodologies

Sustainable Development of High-Volume Fly Ash Self-Compacting Concrete Incorporating Bottom Ash and Recycled Concrete Aggregates

Incorporating by-products like coal bottom ash (BA), recycled concrete aggregates (RCA), and fly ash (FYA) in concrete is an essential step toward green and sustainable development in construction sector. For sustainable utilization of RCA as natural coarse aggregates (NCA) and BA as natural fine aggregates (NFA) in high-volume fly ash self-compacting concrete (HVFYA-SCC), this study investigates ten numbers of designed HVFYA-SCC mixes. HVFYA-SCC mixes were developed with varying content of ordinary Portland cement, FYA (60%), NCA, NFA, RCA (maximum 50%) and BA (maximum 30%). The substitution of 20% BA and 25% RCA in HVFYA-SCC mixes increased compressive and split tensile strengths after 120 days of curing, while further substitution (s) led to a drop in properties. Similarly, at 120 days of curing the maximum electrical resistivity was achieved (20% BA and 25% RCA), while all mixes under ultrasonic pulse velocity resulted in the ‘good category.’ Also, the same mix resulted in lower sorptivity values for maximum curing. A good correlation (R2 0.8) was observed among the tested mechanical and durability properties. The outcomes of this study indicate valuable information on the performance and potential benefits of using HVFYA-SCC in advanced structural designs for upcoming concrete industry. Furthermore, the findings successfully support the implementation of designed concretes as sustainable and environmentally-friendly alternative to conventional concrete(s)

Impact assessment of frontline demonstrations on green gram: Experience from rainfed condition of Rajasthan

Pulses being rich in quality protein, minerals and vitamins are inseparable ingredients of diet of majority of Indian population. Despite high nutritive value of pulses and their role in sustainable agriculture desired growth rate in production could not be witnessed. The domestic production of pulses is consistently below the targets and actualdomestic requirements are also higher, due to these pulses are being imported. The Krishi Vigyan Kendra Pali has carried out frontline demonstrations on green gram covering an area of 26.5 ha of farmers’ field to exhibit latest production technologies and compared it with farmer’s practice. The study in total 40 frontline demonstrations were conducted on farmers’ fields in villages viz., Kishanagar, Bedkallan, Boyal, Kushalpura and Balara of Pali district of Rajasthan state during 2014, 2015 and 2016, to demonstrate production potential and economic benefit of improved technologies comprising sowing method, nutrient management and chemical weed control and adoption of whole package of practices for the crop. After sowing of seed application of weedicide Pendimethalin (within two days after sowing) at 1.0 kg/ha in 500 liters of water used for effective control of the weeds during kharif season in rainfed condition. The findings of the study revealed that the demonstrated technology recorded a mean yield of 982 kg/ha which was 35.5% higher than obtained with farmers’ practice (755 kg/ha). Higher mean net income of Rs. 46030/ha with a Benefit: Cost ratio of 4.3 was obtained with improved technologies in comparison to farmers’ practices (Rs. 38775/ha). The frontline demonstrations conducted on green gram at the farmers’ field revealed that the adoption of improved technologies significantly increased the yield as well as yield attributing traits of crop and also the net returns higher than the farmers’ practices. So, there is a need to disseminate the improved technologies among the farmers with effective extension methods like training and demonstrations. The farmers’ should be encouraged to adopt the recommended package of practices realizing for higher returns

Response of bio-regulators to morphology and yield of clusterbean [Cyamopsis tetragonoloba (L.) Taub.] under different sowing environments

An experiment was conducted during kharif season of 2014, aims of the experiment were to investigate suitable sowing environment and bio-regulator and its effect on clusterbean (Cyamopsis tetragonoloba (L.) Taub.), experimental treatments were applied foliar spray of thiourea (500, 1000 ppm) and salicylic acid (50, 100 ppm) at 45 and 60 days after sowing under normal (15 July) and late (30 July) sowing environments. Normal sowing performed well as compared to late sowing, in respect to all morphology and yield parameters. Amongst foliar spray, significantly higher plant height (100.17 cm), number of branches per plant (7.99), leaf area index (4.85), seed yield (9.19 q/ha) and harvest index (29.39) were recorded in foliar spray of thiourea 500 ppm as compared to all other bio-regulators spray level. Similarly, salicylic acid 100 ppm found statistically at par with thiourea 500 ppm foliar spray at 45 and 60 DAS. Impacts of climate change have significant reflections on clusterbean productivity. Sowing dates plays a vital role to determining the productivity of clusterbean with bio-regulators spray by controlling the environmental factors
