Intercultural Operations in Brinjal Cultivation
Intercultural Operations:
Inter-tillage or hoeing with some hand drawn implement .should be done in the crop (in such a way that a root system is-not damaged) to check the weeds. These operations should be fairly deep and close when plants are very small, but they should be made shallow as plants develop. The most serious weed in brinjal and other solanaceous crops is qrobancbai sp. It is a root parasite and should be controlled carefully according to the measures suggested by the experts.
According to Choudhury (1967), fruit set can be increases with plant regulators. These chemicals are either used for seed treatment or sprayed over the plants. Para-chlorophenoxyacetic acids, 2, 4, dichlorophenoxy-acsfic acid and napthaleneacetic acid, have been found effective for this. Out of these chemicals the cheapest and easily available is 2,4-D. The seed can be soaked for 24 hours in a solution of 2, 4-D at 4 to 5 ppm before sowing or spraying the whole plant with 2, 4-D solution at 2 ppm when the first few flower clusters appear. These treatments give about 50 per cent earlier and higher fruit set.
