Response of Stubble Shaving Times on Ratoon Yield of Different Sugarcane Genotypes

Ratooning is common practice done in sugarcane with purpose of reducing the total cost of cultivation and early cane maturity. More than 35% of sugarcane productivity is lost due to improper attention of the farmers towards ratoons. Majority of farmers reported that the ratoonability wasn’t good when harvested in December-January. This experiment was carried out to find the appropriate ratoon shaving time with response to different varieties in sugarcane ratoon crop in the year 2018/19 at national sugarcane research project, Jitpur, Bara. The experiment was conducted in split plot design with four levels of cane genotypes as Co – 0238, CoLk – 94184, Co – 0233 and CoS – 07250 as the main plot factor while four harvesting dates as sub plot factor with three replications. Observations of a number of millable canes, single cane weight, plant height and single cane diameter were recorded, tabulated and analyzed in R-studio. Ratoon stubble shaving in the month of November had the highest number of millable canes (88079/ha) which wasn’t significantly different from the stubble shaving in the month of December, January. Likewise, highest cane yield (60.04 mt/ha), single cane weight (0.757 kg), cane diameter (2.11 cm), plant height (1.82 m) were found in early stubble shaving dates. Cane Yield and various yield parameter shows better performance in early ratoon shaving periods i.e. from November to January than late ratoon shaving dates

Sugarcane Response and Its Related Gene Expression under Water Stress Condition

This review paper is to study the different responses expressed by the sugarcane when exposed to water stress conditions, that is, waterlogging and drought. Water stress is one of abiotic stress affecting sugarcane productivity and the development of water-use efficiency and the morphological character get varies with genotypes, duration and intensity of stress and types of tissue damage and expression of variable patterns of a gene that makes a high degree of complexity on sugarcane under water stress condition. Since, there is little stepping towards sugarcane crops coming from genetics, agronomics, and molecular biology. These studies provided the framework for researching the morphological basis of genetic variation and mycorrhizal colonization in water stress tolerance and yield improvement under water-limited conditions

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
