Associated with paddy

Brown spot caused by (Bipolaris oryzae) is a persistent disease of Paddy (Oryza sativa L.) and associated with reduction in economic yield in the areas under dry and semi dry climate, with the nutrient poor field. Part of the paddy area under cultivation is salt affected in India, having longer water stagnation capacity, though having deficiency of organic matter and other essential nutrient, where during monsoon season only paddy is grown.

A field experiment was conducted during Kharif season of 2016-17, at the farmer’s fields in village Munshikhera, district Unnao to study the efficacy of halophilic bio fertilizers, Halo Azotobacter (Halo-Azo) and Halo Phosphate Solubilising Bacteria (Halo-PSB) on the growth and productivity of salt tolerant variety of paddy (CSR-36) and residual fertility of post-harvest soil. It is observed that potential salt tolerant variety of paddy in association with halophilic beneficial microbes together can play a greater role to improve the productivity of paddy as well as soil fertility.

Methylobacterium spp. are a group of bacteria known as pink-pigmented facultative methylotrophs (PPFMs) capable of growing on single carbon compounds such as formate, formaldehyde, and methanol as well as on a variety of multicarbon compounds having no carbon-carbon bonds. They are distributed ubiquitously in the plant phyllosphere and rhizosphere and have been isolated from many species of plants. Methylotrophs are known to play an important role in increasing crop yield and soil fertility.

Genes associated with arsenite uptake and transport in rice plants (i.e., OsLsi1, OsLsi2, OsLsi3, OsLsi6 and OsABCC1) have been identified to date. However, their expression over time during the whole growth period of rice under arsenite stress conditions is still poorly understood.

In Rice Value Chain, a value chain starts with the production of a primary commodity i.e. paddy (Farmers), ends with the consumption of the final product (rice and associated byproducts) and it includes all the economic activities undertaken between these phases such as processing, delivery, wholesaling, and retailing. A comparative study of value chain study of rice was undertaken in East Champaran district of Bihar and Davangere district of Karnataka.

The study was carried out with an objective to study various socio-economic, sociopersonal, socio-psychological and communication variables associated with paddy-cumfish cultivation and the constraints perceived by the farmers in the low lying paddy fields of Kakching block in Thoubal district of Manipur. Purposive along with simple random sampling techniques were adopted for the study.
