Before sowing, the seeds are to be treated with Trichoderma viride @ 4 gm per kg or Pseudomonas fluorescens @ 10 gms per kg of seeds.
The seeds can be directly sowed three numbers in a pit or can be grown initially in a polythene bag filled with same soil and transplanted at the pits after a healthy growth of the plant. Thinning to two plants after healthy growth of plants to be carried out.
The plants are sown at a spacing of 150 X 200 cm.
The seeds are sown following two methods. One is Bed type the other is Pits or furrows type. Generally the Bed type method, is followed for Trellis or raised type of growing and Pits type is followed for ground trailing method of growing.
