Groundnut being arid agriculture crop is facing serious pod yield reducing threats. The global warming further deteriorates this menace and now drought emerges as major limiting factor in groundnut yield maximization. In this study different genotypes were evaluated at three different Agro-Eclogical Zones to identy high pod yielding and adopted groundnut genotype(s) for commercial cultivation. The book in hand certainly provides base-line information and guiding principles for groundnut researchers, planners, students, progressive growers and organizations. Therefore, it should be in each...

This book primarily focuses on the importance of natural herbicides (allelochemicals) in biological control of weeds. Trials were carried out to investigate efficacy of sole natural herbicides and their mixture with reduced doses of synthetic herbicides to control weeds with an over all objective of minimizing reliance on synthetic herbicides. Specific objectives of the study were: to assess the effect of natural herbicides on seed germination and seedling growth of wheat and its weeds under laboratory conditions, to screen natural herbicides and evaluate the possible synergistic ...

The book in hand provides base-line information on the chemical constituents of Primula macrophylla D. Don like isolation and characterization of nine compounds namely -sitosterol, flavone, 2 -methoxy flavone, 3 -methoxy flavone, 3.3 -dihydroxy chalcone, -sitosterol glucoside, 2 -hydroxy 7-O- - D-glucoside "macrophylloside" and two triterpenoid saponins, PM-F and PM-F2 . Four compounds namely 3.3 -dihydroxy chalcone, macrophylloside, PM-F and PM-F2 were new while 2 -methoxy flavone and 3 - methoxy flavone are reported for the first time from the family Primulaceae and are very rare. -...
