    Organic production is carried out under an extensive regulatory setup because organic products are sold as value-added products with certified organic labelling in developed countries. Production is strictly monitored at every step in production chain. Organic production apart from being eco-friendly offers higher net returns per unit area compared to conventional agriculture. Organic production uses traditional tillage systems, crop rotations, crop residues, animal manures, legumes, green manures, off-farm organic wastes, mineral bearing rocks, and biological pest and weed control to maintain soil productivity. Thus, an organic farm should be a self contained system of production with minimal dependence on external inputs. Those farms having dairy as one of the active components will have to convert to organic livestock management so that manures supplied are as per requirements for organic production. The dairy products can also be certified organic to fetch higher prices. Organic farming is a highly labour intensive enterprise. Some of the major organic accreditation agencies are IFOAM (International Federation of Organic Agriculture Movements), FiBL, Demeter and many more. APEDA has also developed national standards for organic production. Indian farmers face many challenges in adoption of certified organic production. Some of the important organic production requirements as per national standards for organic production have been developed by APEDA.Genetically engineered cultivars or plant materials are not permitted in organic production. Some of the important organic production requirements as per national standards for organic production have been developed by APEDA. Some of the important organic production requirements as per national standards for organic production have been developed by APEDA.Before products from a farm/project can be certified as organic, inspection shall be carried out during the conversion period. To ensure a clear separation between organic and conventional production, the certification programme (agency) shall inspect, where appropriate, the whole production system. Organic production is one area of agriculture which can convert India’s ‘Green Revolution’ into ‘Evergreen Revolution’

    We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV/c2/c^2 produced in the gluon-gluon fusion, WHWH, ZHZH, ttˉHt{\bar{t}}H, and vector boson fusion processes, and decaying in the HbbˉH\rightarrow b{\bar{b}}, HW+WH\rightarrow W^+W^-, HZZH\rightarrow ZZ, Hτ+τH\rightarrow\tau^+\tau^-, and HγγH\rightarrow \gamma\gamma modes. The data correspond to integrated luminosities of up to 10 fb1^{-1} and were collected at the Fermilab Tevatron in ppˉp{\bar{p}} collisions at s=1.96\sqrt{s}=1.96 TeV. The searches are also interpreted in the context of fermiophobic and fourth generation models. We observe a significant excess of events in the mass range between 115 and 140 GeV/c2c^2. The local significance corresponds to 3.0 standard deviations at mH=125m_H=125 GeV/c2c^2, consistent with the mass of the Higgs boson observed at the LHC, and we expect a local significance of 1.9 standard deviations. We separately combine searches for HbbˉH \to b\bar{b}, HW+WH \to W^+W^-, Hτ+τH\rightarrow\tau^+\tau^-, and HγγH\rightarrow\gamma\gamma. The observed signal strengths in all channels are consistent with the presence of a standard model Higgs boson with a mass of 125 GeV/c2c^2

    Evidence for a Particle Produced in Association with Weak Bosons and Decaying to a Bottom-Antibottom Quark Pair in Higgs Boson Searches at the Tevatron

    We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron p[bar over p] collisions at √s=1.96  TeV, correspond to integrated luminosities of up to 9.7  fb[superscript -1]. The searches are conducted for a Higgs boson with mass in the range 100–150  GeV/c[superscript 2]. We observe an excess of events in the data compared with the background predictions, which is most significant in the mass range between 120 and 135  GeV/c[superscript 2]. The largest local significance is 3.3 standard deviations, corresponding to a global significance of 3.1 standard deviations. We interpret this as evidence for the presence of a new particle consistent with the standard model Higgs boson, which is produced in association with a weak vector boson and decays to a bottom-antibottom quark pair

    We combine searches by the CDF and D0 collaborations for a Higgs boson decaying to W+W-. The data correspond to an integrated total luminosity of 4.8 (CDF) and 5.4 (D0) fb-1 of p-pbar collisions at sqrt{s}=1.96 TeV at the Fermilab Tevatron collider. No excess is observed above background expectation, and resulting limits on Higgs boson production exclude a standard-model Higgs boson in the mass range 162-166 GeV at the 95% C.L
