Effect of Foliar Spray Extracts of Ulva lactuca L. on Chemical Composition and Morphological Parameter of Test Plant Solanum melongena L. var. 'Pancha Ganga'

摘要

Use of various chemical fertilizer and pesticide disturbs the natural balance of nutrients, which causes severe problems like reducing soil fertility, soil erosion, desertification and ultimately the destruction of soil flora as well as soil fauna. Due to chemical fertilizers and pesticides the whole rhizosphere is getting polluted. These synthetic chemicals are poisoning the soil, killing microorganisms present in the soil, stunning plants and causing harmful diseases in plants, animals and in man also. Therefore, biofertilizers are used as supplement for better agricultural output and to maintain the quality of soil and yield of grain production. Now, it is an established fact that algae, especially seaweeds can be used as good renewable source of biofertilizers.To find out the effect of 10(-1)% concentration of Ulva lactuca L. class Chlorophyceae use as foliar spray on test plant Solanum melogena L. var. 'Pancha Ganga'. Foliar spray of Ulva lactuca L. continusally spray on test plant, increase in chemical composition of test plant such as increase in Chlorophylls, Proteins and Carbohydrates before flowering, after flowering and at fruiting stage of test plant. Statistically it was calculated by T- test and F- test, and it was proved that increases the chemical composition of various stages of test plants, as well as increase in morphological parameters of test plants.
