Excessive use of chemical fertilizers and pesticides in agriculture has come into severe criticism by the environmentally conscious people who opine that the increase in agricultural production was achieved at the cost of soil health. Organic farming is not mere non-chemical agriculture but it is a system of farming based on integral relationships among soil, water, plants, soil microflora and overall relationship between plant and animal kingdom of which man is the apex animal. The totality of these relationships is the backbone of organic farming. The principal elements to be considered...

Crop physiology is concerned with the processes and functions of the crops at cellular, sub-cellular and whole plant levels in response to environmental variables and growth. In short, physiology is the study of functional aspects of crop plants. This book is published for the purpose of competitive examination preparation like JRF, SRF, M.Sc. and Ph.D. Entrance and ICAR examination.This Book contains four chapters starting from cell organelles, soil water relations, Photosynthesis, Respiration, Plant mineral nutrition and Plant Growth Regulators.

Investigations were undertaken to study the impact of salt stress (Nacl) in concentrations on seed germination and seedling growth of Green gram (CO5, CO6) and Black gram (CO 6, CO 8). Seed germination percentage, seedling growth characters, physiological and bio-chemical parameters were estimated at 10 days after sowing in Petridish. The stress was imposed during sowing time with different concentrations viz., 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 ppm. The increased seed germination percentage was noticed in control (distilled water) treated seeds and very less reduction was observed in T2...
