    In order to assess the performance of some new genotypes of brinjal (Solanum melongena L.) under tarai condition of Uttarakhand, an investigation was carried out at Vegetable Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, during autumn-winter cropping season of 2012-13. The experiment was laid out in Randomized Complete Block Design with 4 replications and 9 treatments viz. PB-300, PB-301, PB-302, PB-303, PB-304, PB-305, Kashi Tarun, Punjab Sadabahar and Pant Samrat. To have comparative study, growth characters, per cent fruit infested by fruit borer, fruit yield and finally economics were also worked out. The findings revealed that none of the new genotypes in this study could supersede the local checks in respect to yield related attributes, per cent infested fruit by borer and economics. Amongst 6 genotypes and 3 commercial cultivars, variety Kashi Tarun proved the best with respect to fruit yield (490.73 q/ha) and B:C (2.43). It is also less infested by fruit borer. The per cent infested fruit by borer was 7.16 %. Variety pant samrat and pant bahar were also considered promising with 385.70 and 369.33 q/ha marketable fruit yield

    Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

    The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
