A field experiment was conducted during June-January seasons of 2016-17 and 2017- 18 at ICAR- Central Institute of Agricultural Engineering, Bhopal to study the growth, yield and economics of pigeon pea cultivation under drip irrigation in combination with plastic mulching. The study was laid out in randomized block design with four treatments viz., control, drip irrigation, drip with black mulch and drip with silver mulch and replicated five times. The yield attributes viz., plant height (342cm), no of branches (17), pods per plant (1070), seeds per pod (3.78), yield (4330 kg/ha), hundred seed weight (13.89 g) and stalk yield (9932 kg/ha) were found maximum under silver colour mulch treatment followed by black colour mulch. Water use efficiency (WUE) was found highest (7.6 kg/ha-mm) for crop cultivated with drip irrigation under silver colour mulch as compared to other treatments. Cost of cultivation was higher under the mulching conditions (Rs 65936/ha) as compared to flood irrigation (Rs 20936/ha). However, the net returns were highest under silver mulch (Rs 128914 /ha) followed by black mulch (Rs 111724/ha) over flood irrigation (Rs 25864/ha). The B: C ratio was also higher under silver mulch (2.96) followed by black mulch (2.69) as compared to drip irrigation (2.08) and without mulch (1.91). The net seasonal return, benefit cost ratio and water use efficiency were found to be highest for pigeon pea under drip irrigation with silver mulch followed by black mulch.
