We present a new short-period brown dwarf (BD) candidate around the star TYC 1240-00945-1. This candidate was discovered in the first year of the Multi-object APO Radial Velocity Exoplanets Large-area Survey (MARVELS), which is part of the Sloan Digital Sky Survey (SDSS) III, and we designate the BD as MARVELS-1b. MARVELS uses the technique of dispersed fixed-delay interferometery to simultaneously obtain radial velocity (RV) measurements for 60 objects per field using a single, custom-built instrument that is fiber fed from the SDSS 2.5 m telescope. From our 20 RV measurements spread over a ∼370 day time baseline, we derive a Keplerian orbital fit with semi-amplitude K = 2.533 ± 0.025 km s −1 , period P = 5.8953 ± 0.0004 days, and eccentricity consistent with circular. Independent follow-up RV data confirm the orbit. Adopting a mass of 1.37 ± 0.11 M for the slightly evolved F9 host star, we infer that the companion has a minimum mass of 28.0 ± 1.5 M Jup , a semimajor axis 0.071 ± 0.002 AU assuming an edge-on orbit, and is probably tidally synchronized. We find no evidence for coherent intrinsic variability of the host star at the period of the companion at levels greater than a few millimagnitudes. The companion has an a priori transit probability of ∼14%. Although we find no evidence for transits, we cannot definitively rule them out for companion radii 1 R Jup .

Marigold is one of the most important commercially grown loose flower crops in India. It is used as loose flower or to make garlands, which are extensively used in the religious and social functions. Marigold is broadly classified into two groups, viz., African marigold (Tagetes erecta L.) and French marigold (Tagetes patula L.). About 342000 ha of area is under floriculture producing 1760000 MT of loose flowers and 769000 MT of cut flowers annually (2017-18 advanced estimates). In order to sustain the growth the floriculture sector must constantly innovate to produce novel products. To meet the objective RBD and CACP tools were used for data analysis. The result shows the T7 perform better in both way i.e. growth aspects as well as economically.

The share of agriculture in gross domestic product has registered a steady decline from 36.4 per cent in 1982-83 to 20 per cent in March 2020-2021. Yet this sector continues to more than half a billion people providing employment to 52 per cent of the workforce. In the western Uttar Pradesh two cropping systems mainly Rice-wheat and sugarcane-wheat covers a larger area under production system. In Combined, both these cropping systems add up around to 12 million hectare area but the major part falls under North-West India. A sample of 80 famers who have livestock were selected for sample collection. For analysis the data Average weighted mean and CACP cost concept were used for calculation of economics of farming systems.There for the net return per hectare in small, medium and large category was Rs. 174390.40, 161003.60 and 152396.80 respectively. It was also observed the net return was higher in Sugarcane-Wheat cropping system than the Rice-Wheat cropping system.
