ABSTRACT

A field experiment was conducted to identify suitable plant spacing and harvesting methods for green leaves production of broadleaf mustard during off-season (April to June). The experiment was designed in two factor factorial arrangements in randomized complete block design with three replications. First factor was harvesting method and the second was different plant spacing. The study has shown that green leaves of broadleaf mustard can be successfully produced in the dry season in the areas of high and upper mid hills having irrigation facility. Between periodic harvest and whole plant harvesting, periodic harvest yielded significantly higher (P<001) green leaves. The results revealed that the green leaf production was significant (P<001) among the different plant spacing. Results showed that 45x10 cm spacing was suitable for periodic harvest and 30x10 cm for whole plant harvest. The results have clearly shown that plant population per unit area can be reduced by at least three folds for periodic harvest and four folds for whole plant harvest then that of normal season for the dry season production.
