Nitrobenzene (Flower Boost) Nitrobenzene is combination of nitrogen and plant growth regulators extracted from Sea weeds A suitable solvent was selected as nitrobenzene. Required preservatives have been incorporated to prevent detritions. Best quality emulsifiers were used which is responsible for highest penetration of hormones in plant. This has provided a new look to formulation.Nitro benzene produce best results in combination of plant growth regulators which have capacity to: Increase flowering in plant. Prevent flower shedding. It enhance early flowering. Plants take less time to flower. Yield contributing characters like plant height in crease is 8-10%.Number of branches per plant increase by 15-20%.Number of flowers per cluster increase by 33-35%.20-30% increase in number of fruits per plant were recorded. Fruit weight increase is 20-25 %.Bigger fruits are produced. Total yield increase due to nitrobenzene application is 35-50%. Quality characters like TSS (Total soluble solutes) in crease by 6-7% & acidity by 10-12% Ascorbic acid 7-10% and total sugar % were 5-7.5% more was recorded It was tried in following crops and yield increase was recorded such as: Cotton (45-50%); Chilies-(50-55%);Tomato(45-50%) ;Peas -(45-50%); Jasmine -(30-35%);Paddy -(25-30%); Pulses -(20-25%); Soybean (30%).
