An experiment of Mustard was conducted during Rabi, 2017 on loamy sand soil (Jaipur, Rajasthan). The experiments were aimed to see the impact of organic, inorganic fertilizers and pesticides on the plant growth and other parameters. Observations were made on growth parameters and some physiological and biochemical parameters such as plant protein content, plant nitrogen content, plant carbohydrate content, chlorophyll content (chlorophyll a, chlorophyll b and total chlorophyll) and pesticide residue using standard techniques. The experiment consisted of five treatment levels (T1, T2, T3, T4 and T5) and they were tested in randomized block design with four replications. In total twenty plots were maintained. Results revealed that in treatment level, T5, plant growth response remained the best. In this treatment level only vermicompost was applied and no other material was added
