Biochemical Evaluation of Forage Sorghum for Stress Tolerance

Abiotic stresses are the major limiting factors in plant growth. With continuous increment in scarcity of water and increased salinization of soil and water, it is estimated that more than 50% of all arable lands will be affected by salinity and drought by 2050. Plants are often exposed to both, soil and atmospheric water deficit during their life cycle. The frequency and intensity of droughts is increasing as a result of global climate change. Understanding how plants respond to water stress is thus crucial for the estimation of impacts of climate change on crop productivity and ecosystem functioning. The knowledge about the mechanism adapted by plant to respond to drought, salt and co-occurring stresses can play an important role in stabilizing crop performance under drought and saline conditions. Sorghum (Sorghum bicolor L.) is an important crop in many parts of the world. It is utilized as food, fodder and several industrial purposes. In general, sorghum is known to be more tolerant to any stresses including heat, drought, salinity and flooding

Information and communication technology in agribusiness: A study of mobile applications in perspective of India

Federation of Indian Chambers of Commerce and Industry in one of its finding in 2019 stated that about 58%  Indians are dependent on agriculture and agriculture sector make about 15.96 % of India’s GDP. To get the best agriculture inputs and best harvest price is the big question for Indian farmers; thus, we can say that “Agriculture is the foundation of the Indian economy”. With the origin of Mobile Applications (m-apps) for agriculture and a huge dependency on Information and Communication Technology (ICT) in agribusiness, the scenario in rural India has been changing rapidly. Since India’s economy depends mainly on agriculture, there is a lot of potential for Information and Communication Technology and mobile applications for agribusiness and its marketing. With growing smartphones with m-apps penetration in rural India, the agribusiness in rural belts of India is set for extension and further digitalization to revolutionize the agriculture sector. In recent years, nearly all Indian farmers possess a mobile, and 50%are smartphones with internet connections. With Government's new legislative policy changes as the Digital India programme, mobile applications in India's rural belt cannot remain isolated. Digital India will connect rural Indians farmers worldwide through the internet and mobile applications and provide them with all necessary upliftment in agribusiness in India. This study has focused on the ICT and m-applications used in farming today and how they have changed agribusiness by providing a digital platform and with their impact on agribusiness

Synthetic Polymer Based Coating of Fodder Cowpea Seeds Enhances Germination and Vigour

In Indian arid and semi-arid conditions, comparatively less fertile lands are allotted to forage crops. In addition, erratic weather condition makes the situation more complex where proper seedling emergence and establishment of pastures with economic use of input remains a big question. Our view is that crop seedling production from seed sown into arid or semiarid environments could be significantly enhanced by the use of simple seed coating technologies. Such approaches would make use of newly synthesised seed coat-applied polymers that could be used to hold the desired supplements like powerful germination enhancement chemicals and plant protectants with seed to support both germination and seedling establishment under the crucial stages. This approach would be expected to increase the rate and speed of germination, thereby bringing the uniformity in plant population even under stressful (drought) growing conditions. On the other hand, cowpea seed are highly susceptible to insect pest during storage in addition to seed borne diseases. Hence, coating of seed was envisaged in order to protect the seeds from pest attack and boost initial seedling vigour

Innovative Technologies for Enhanced Availability of Bajra-Napier Hybrid Rooted Slips

Livestock occupies a crucial position in Indian agriculture and directly contributing 4.1% of total GDP of the country. India, with 2.29% of the world land area, is maintaining about 10.71% of the world’s livestock population. To sustain the present milk growth rate of 4.04% and for further expansion to meet the demands of ever growing human population, livestock needs sustainable supply of feed material. The area under fodder cultivation is estimated to be about 4% of the gross cropped area which remained static for the last four decades.The traditional grazing lands are gradually diminishing because of urbanization, expansion of cultivable area, grazing pressure and industrialization etc. These factors resulted in severe shortage of feed and fodder to the extent of 26% in dry-crop residues, 35.6% in green fodder and 41% of concentrates (Anon, 2013). To reduce the demand and supply gap, the production and productivity of fodder crops needs to be enhanced. The utilization of non-cultivable space viz., field bunds, common grazing lands, backyards apart from regular cultivation of high biomass species like Bajra-Napier hybrid (BN hybrid), guinea grass, Trispecific hybrid helps in enhanced production of green fodder. Bajra-Napier hybrid is one of the high biomass grasses with fodder potential of 300 tons/ha/year. However, this grass can be propagated only through rooted slips as it does not form any viable seed. Several varieties suitable to different agro-climatic zones were released for the successful cultivation of this grass throughout India. Due to increasing demand both from small and marginal farmers as well as well-structured large scale diary industry, there is severe shortage of rooted slips of this grass. The traditional uprooting of tussocks not only destructs the mother tussock but also highly labour intensive and difficult to transport to long distances. Keeping in view of all these constraints, two novel technologies were developed for the large scale multiplication of BN hybrid rooted slips

Anthesis Dynamics, Pollen Availability and Enhancement of Seed to Ovule Ratio in \u3cem\u3eChrysopogon fulvus\u3c/em\u3e

Under the present scenario of severe green fodder shortage (64%) in India, grassland offers an opportunity to enhance fodder availability. To revitalize the existing denuded grasslands, seed is the best propagating material. Availability of quality seed in forage grasses is less than 20% of actual requirement/ demand. Hence, there is a need to enhance the production and productivity of grass seeds. Even the available grass seeds have very low germination percentage, which is mainly due to the absence of a caryopsis inside the fluffy seed material. Chrysopogon fulvus, commonly known as Guria grass or red false beard grass, is a tufted perennial tropical grassland species, with good palatability and green fodder potential of \u3e20 t/ha. With its ability to grow under annual rainfall of 300-1200 mm it is well suited for the rainfed situation of Indian grasslands. As per Indian minimum seed certification standards (IMSCS), the germination percentage of C. fulvus is only 15%. The low germination coincides with the low seed setting (14-18%) as recorded in bulk harvested sample by Bahukhandi et al. (2011). Enhancement of seed to ovule ratio not only increases germination percent but enhances productivity per se. With this background, the present study was undertaken to understand the reproductive morphology, pollen availability and effect of exogenous application of chemicals for enhancement of seed to ovule ratio in C. fulvus

Quality Seed Production of Range Grasses--A Major Constraint in Revitalising Tropical Pastures

Only 4% of India’s geographical area of 326.82 M ha is under pastures. Socioeconomic and ecological consequ-ences of land degradation are affecting 85 M ha of rangelands/grasslands. To provide sufficient milk for the ever-growing population, current milk production of 128 M t must increase to 160 M t by 2020. To make this possible, an additional 825 M t of green fodder is required. Increasing the area producing green fodder is difficult because of severe competition from food crops. Revitalising the denuded grasslands is the most plausible means for improving the availability of green fodder. This needs mission mode programs with participation of the people

Migration as adaptation strategy to cope with climate change: A study of farmers’ migration in rural India

Purpose – This study aims to evaluate the link between climate/weather change and farmer migration in Bihar, India. The influence of cognitive conditions and climate-related stress on farmer migration decisions and the socioeconomic characteristics of migrating and non-migrating farm households are analysed. The focus is the role of migration in access to climate and agricultural extension services and the contribution of migration to enhanced farmer coping capacity. Design/methodology/approach – A primary survey was conducted of farm households in seven districts of Bihar, India. Farmer perceptions of climate change were analysed using the mental map technique. The role of socioeconomic characteristics in farm household migration was evaluated using binary logistic regression, and the influence of migration on access to climate and agricultural extension services and the adaptive capacity of migrating households was investigated using descriptive statistics. Findings – Climate-induced livelihood risk factors are one of the major drivers of farmer’s migration. The farmers’ perception on climate change influences migration along with the socioeconomic characteristics. There is a significant difference between migrating and non-migrating farm households in the utilization of instructions, knowledge and technology based climate and agriculture extension services. Benefits from receipt of remittance, knowledge and social networks from the host region enhances migrating households’ adaptive capacity. Originality/value – This study provides micro-evidence of the contribution of migration to farmer adaptive capacity and access to climate and agricultural extension services, which will benefit analyses of climate-induced migration in other developing countries with higher agricultural dependence. In addition, valuable insights are delivered on policy requirements to reduce farmer vulnerability to climate change
