Cost-Benefit analysis of ferti-drip irrigation in arecanut (Areca catechu L.)

Abstract

The experiment on ferti-drip irrigation was conducted at Central Plantation Crops Research Institute, Regional Station, Vittal, Kamataka, India during December 1996 to May, 2006 with four levels offertilizers viz., 25, 50, 75 and 100percent of recommended fertilizer dose (100:40:140 g N: P20,: ~O/palmlyear), three frequencies offertigatioo viz., 10,20 and 30 days in 4x3 factorial RBD with two additional controls io two year old arecanut plantation (cv. Mohitnagar). The cost of cultivation during bearing stage in conventional method of arecanut cultivation was Rs. 60,242, while with fertigation it reduced to Rs. 26,377. The increase in net returns with 75 % NPK fertigation at 10 days interval over absolute control was 149%. Mean data of four years (2002-2005) indicated that 75% NPK fertigation at 10 days interval was highly profitable with highest net returns per rupee investment of 4.57 followed 75% NPK fertigation at 20 days interval (4.44). The study revealed that ferti-drip irrigation is highly profitable in arecanut. With adoption of ferti-drip irrigation the advantages accrued were reduced labour charges 00 fertilizer application, weeding and irrigation and diesel charges due to less operational hours.
