Factors Leading to Success in Diversified Occupation: A Livelihood Analysis in India.

Abstract: Purpose: Livelihood diversification is a sound alternative for higher economic growth and its success or failure is conditioned by the interplay of a multitude of factors. The study of the profile of the farmers in which they operate is important to highlight the factors leading to success in diversified livelihoods. Design/Methodology/Approach: A total of 160 households of farmers were selected randomly and were interviewed to collect primary data for the study. To measure the success of diversified occupation a success–failure scale was developed following the steps used by Singh et al., ‘t’ statistics was used to compare the two groups. Discriminant function analysis was used to identify the factors determining success and failure in diversified occupation. Findings: The study revealed that 53% of the diversifiers were successful in their diversified activities. Around 62.50% diversifiers under the high success category were adopted non-farming nature of diversification along with farm diversif...

Genetic Variability and Association of Traits in Mutant Lines of Rice (Oryza sativa L.) for Submergence Tolerance

Abstract: Present investigation was carried out with 240 mutant lines developed from different combination of gamma rays and ethyl methyl sulfonate on three rice varieties i.e FR13A, FR13B and Labella along with three untreated checks (FR13A, FR13B and Labella). These were evaluated for their survival percentage under submerged condition and yield potential along with 9 other morpho-physiological traits using Type 2 modified augmented design during Kharif season of 2017 in the agroclimatic region of north bihar, India. Analysis of variance revealed highly significant differences among the mutant lines for all morpho-physiological characters under study. Higher magnitude of phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability (broad sense) and genetic advance as percentage of mean were observed for number of tillers per plant, number of fertile tillers per plant, relative shoot elongation and survival percentage, indicating that these traits could be used as selection indices for yield improvement and submergence tolerance. Association study revealed that number of tillers per plant and survival percentage had significant positive high to moderate direct association with grain yield per plant under submergence condition. Thus, these traits may be used as selection criteria in further crop improvement programmes for submergence tolerance.

Assessment Of Hydraulic Performance Of Drip Emitters For Adoption In Hilly Terrain Of North‐Eastern Region Of India

Abstract: The north-eastern region of India, although rich in land and water resources, often suffers from a water-scarce situation particularly during the non-rainy season. The steep terrain conditions do not support conventional irrigation systems and therefore micro-irrigation system needs to be promoted. In micro-irrigation systems, maintaining uniformity of application is necessary to achieve a satisfactory crop yield. Maintaining the system hydraulics is a challenge due to the terrain conditions and equipment available. A study was conducted to observe various uniformity parameters of selected emitters at five different operating pressures, viz. 0.5, 0.75, 1.0, 1.25 and 1.5 kg cm–2. In the study it was observed that the discharge variation of the selected emitters was between 8.7 and 39.7%. The uniformity coefficient varied from 0.9 to 16.6, where the distribution uniformity and statistical uniformity varied from 81.1 to 99.1% and 83.4–99.1% respectively. The emitter flow variation ranged from 0.03 to 0.49 in the range of 0.51.5 kg cm–2. The emitter exponent indicated that the values ranged from 0.20 to 0.55. All these values were far from the manufacturer's value. From the study we can interpret that the emitting system needs to be tested before adoption in the field to ensure uniformity of water application. Copyright © 2016 John Wiley & Sons, Ltd.

Role of State Agricultural Universities and Directorates of Extension Education in Agricultural Extension in India

Abstract: In India, the first SAU was established in 1960 at Pantnagar in Uttar Pradesh The SAUs were given autonomous status and direct funding from the state governments They were autonomous organizations with state-wide responsibility for agricultural research, education and training or extension education The establishment of the SAUs, based on a pattern similar to that of the land-grant universities in the United States, was a landmark in reorganizing and strengthening the agricultural education system in India These universities became the branches of research under the ICAR and became the partners of the National Agricultural Research System (NARS) The green revolution, with its impressive social and economic impact, witnessed significant contributions from the SAUs, both in terms of trained, scientific work force and the generation of new technologies However, most of the agricultural universities in India continue to be dominated by top-down, monolithic structures that follow a limited extension mandate None of the post-Training-and-Visit (T&V) system extension reforms could revitalize it to meet the demands of a changing agricultural context The profusion of uncensored information through mass media and cyber sources has long-term consequences of generating public distrust and alienation from agriculture This is attributed to the lack of a proper mechanism for verifying the accuracy and viability of the information transmitted As in most of the developing countries, transfer of technology remained largely in the domain of the State Department of Agriculture (DOA), and SAUs are mandated to serve only a limited extension role in technology dissemination activities The paper tries to critically review the extension activities of the SAUs and their Directorates of extension Education in India
