EFFECT OF CARBOFURAN ON THE FORMATION OF SOME BIOMOLECULES IN BRINJAL (SOLANUM MELONGENA L.) LEAF

Abstract

The present work was carried out with the objective to study the effect of carbofuran on the quantitative formation of carbohydrate, total free amino acids, protein, total phenol and total chlorophyll contents in brinjal leaf as recorded on 1, 7, 14, 21, 28 and 35 days after application (DAA). The carbohydrate content decreased to the extent of 3.36, 4.53 and 4.60% respectively against control (T₁: 0), recommended (T₂: 33.0 kg ha^–1) and double of recommended (T₃: 66.0 kg ha^–1) doses of carbofuran formulation on the 35^th DAA in comparison with 1^st DAA. The total free amino acid content decreased to 42.82, 45.84 and 49.89% respectively against the above doses. In case of protein content also an overall decrease of 45.28, 43.10 and 45.61% with regards to 1^st DAA was observed. The total phenol content, on the contrary, recorded an increase of 18.85, 21.77 and 5.35% respectively in case of above three doses. The total chlorophyll content again exhibited a decrease of 20.99, 22.73 and 36.05% respectively. So the formation of all the biomolecules under study except phenol in brinjal leaf was found to decrease with passage of time as an effect of application of carbofuran.
