Opis:: This study was aimed at investigating profitability of selected coarse cereals production in major producing states of India through analyzing cost, return and profitability of coarse cereals cultivation. Cost concepts and farm business income measures used for analysis the data ranging from 1980-81 to 2011-12. Net return of coarse cereals cultivation was observed to be highest for maize and it was highest in Bihar (Rs. 15,429/ha) and lowest Uttar Pradesh (Rs. -4,006/ha). Net return from cultivation of sorghum was found to be highest in Andhra Pradesh (Rs. 952/ha) and lowest for Madhya Pradesh (Rs. -1,456/ha). For pearl millet net return was highest in Andhra Pradesh (Rs. 4,995/ha) and lowest for Karnataka (Rs. -1,252/ha) whereas cultivation of finger millet was observed to be at a loss.

Insect antifeedant activity
Opis:: Some 6-substituted aryl quinoxalines have been prepared and their purities were checked by their physical constants and spectroscopic data reported earlier. The insect antifeedant activities of these quinolones were studied by leaf-discs bio assay method using 4th instar larvae Achoea Janata L.

LFER Model
Opis:: In this investigation, the authors predicted the effects of substituents on the functional groups of the titled chalcones using Linear Free Energy Relationship through Hammett equation with its constants and Swain-Lupton parameters. The LFER model statistical analysis was carried out using single and multi-linear regression analysis in MS Office 365 XL package. From the LFER analysis outcome, the influence of substituents on the spectroscopic functionality were discussed with their electronic effects such as, polar, inductive, resonance, field and conjugation. The titled compounds were prepared by solvent-free Aldol-Condensation method. The prepared compounds were characterised by their physical constants, micro analysis and spectroscopic data (FT-IR, NMR and Mass).
