INTERCROPPING OF POTATO WITH BRINJAL

Abstract

A field experiment was conducted to find out the spacing of potato brinjal intercropping system and land utilization and economic return at the Regional Agricultural Research Station, Jamalpur during rabi 2017-2018. The experiment was laid out in randomized complete block design (RCBD) with three (3) replications and six treatments. Cultivation of potato with brinjal at potato (60 cm × 25 cm) + brinjal (120 cm × 75 cm), Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm), Potato (50 cm × 20 cm) + Brinjal (100 cm × 75 cm) might be agronomically feasible and economically profitable for potato and brinjal intercropping system as compared to sole treatment. Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm) best performed in gross return, gross margin and potato equivalent yield (PEY 49.14 tha-1) compared with the other treatments. The total yield of intercropped crops was greater than sole cropping, shown by LER>1. The overall advantage of intercropping ranged from 73 to 92%. The highest land equivalent value of 92% was recorded for Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm) arrangements indicated a yield advantage of 92% over sole crop. Viable agronomic option in increasing land use efficiency and increased food security. It is, therefore, imperative to demonstrate the best treatment under farmer’s condition.
