Tea (Camellia sinensis) is an important plantation crop. India has 5,63,980 ha land under tea of which 1,05,685 ha is in Southern India. In India states like Assam (53%), West Bengal (23.9%), Tamil Nadu (11.3%) and Kerala (8.44%) are contributing for major tea production. It is also grown in a small scale in Tripura, Karnataka, Himachal Pradesh, Uttar Pradesh, Sikkim, Bihar, Manipur, Orissa, Nagaland and Arunachal Pradesh. Tea industry in India is more than 150 years old generating the revenue of more than Rs 6,000 crore per annum. The production of tea in India has increased from 250 million kg in 1947 to 1208 million kg in 2013 with 40 per cent increase in area. Optimum application of nutrients in right time ensures optimum tea yield.- Clay Dispersion Induced by Changes in Some Soil Properties in Undulating Salt-Affected Landscapes of Southern Karnataka, India

Effect of sodicity on clay dispersion in salt-affected black soils of the Kabini canal command area in Chamrajnagar district, southern Karnataka was studied. Forty-eight soil samples were collected from nine soil profiles and analysed for physical and chemical properties. The clay dispersion ranged from 0.57% to 62.1%. High positive and negative correlations with exchangeable sodium and exchangeable calcium respectively, with clay dispersion were recorded, which can be predicted better with exchangeable sodium and available soil water. Based on clay dispersion value, 2%, 27% and 71% soils are dispersive, intermediate dispersive and non-dispersive respectively. Based on exchangeable sodium percentage, 50, 21 and 29 soils are dispersive, intermediate dispersive and nondispersive respectively. Application of gypsum and organics reduces the clay dispersion in surface soil. Sub-surface drainage will be more effective. Construction of soil and water conservation structures with pile foundation; providing cement lining for soil stabilization in normal construction; providing drainage lines for the structures; construction after refilling with non-dispersive soil will save the structures in salt-affected soils.Keywords

Meeting the food grain demand of ever growing global population is the big challenge to agriculture sector. Plant disease significantly reduces the production of food crops besides affecting the quality adversely. Losses associated with plant diseases in yield reduction ranging from slight to catastrophic depending upon varying factors. Literature review highlighted that an average yield loss of 42% from the six most important food crops. It is vital to manage plant diseases to avoid the yield loss, which helps to meet the food grain demand in simple means. In other way, disease management is helping us to meet the food grain demand of increasing population under shrinkage of cultivable area.- Nationwide Soil Erosion Assessment in India Using Radioisotope Tracers 137Cs and 210Pb:The Need for Fallout Mapping

Soil degradation induced by erosion represents a major threat to food production and ecosystem service globally, and in India more than 80 Mha have been impacted. In the light of the serious threat, there is a pressing need for a systematic nationwide assessment of land degradation due to erosion. We discuss the potential for using caesium-137 and lead-210 tracers to address this need and the next steps to realizing nationwide implementation.References
