CROP RESPONSES TO INTERACTION BETWEEN PLANT GROWTH REGULATORS AND NUTRIENTS

SUMMARY In the present review a number of examples has been made to cover the aspects of interactions of phytohormones and nutrients in the growth and development of plants which include plant height, leaf area, leaf area index, dry weight, plant growth rate, relative growth rate, crop growth rate, net assimilation rate, carbon dioxide exchange rate, chlorophyll content, photosynthesis, photosynthetically active radiation, ethylene evolution, nitrate reductase activity, carbonic anhydrase activity, nutrient accumulation, nitrogen uptake efficiency, nitrogen use efficiency, nitrogen utilization efficiency, fertilizer use efficiency, productive use efficiency, nutrient use efficiency, seed yield, seed yield merit, seed N content, nitrogen yield merit, merit of genotype biological yield, biological yield, harvest index, oil yield, oil content, acid value, iodine value and saponification value. So the present study indicates that the process of growth and development in addition to the yield of plants is significantly affected by the phytohormones along with nutrients in both irrigated and non -irrigated conditions has been described in detail.
