A field experiment was conducted during 2013 and 2014 at the Regional Centre of ICAR-Central Tuber Crops Research Institute, Dumuduma, Bhubaneswar, Odisha to study the drip fertigation effects on quality characters of elephant foot yam [Amorphophallus paeoniifolius (Dennst.) Nicolson] and water use efficiency of elephant foot yam+green gram (Vigna radiata L.) intercropping system. The experiment was laid out in randomized block design with four replications. The experiment consisted of six treatments i.e. T1-Soil application of fertilizers N-K2O @ 100-100 kg ha-1, T2-Fertigation of N-K2O @ 60-60 kg ha-1, T3-Fertigation of N-K2O @ 80-80 kg ha-1, T4-Fertigation of N-K2O @ 100-100 kg ha-1, T5-Fertigation of N-K2O @ 120-120 kg ha-1 and T6-Fertigation of N-K2O @ 140-140 kg ha-1. During the final land preparation FYM @ 10 t ha-1 was applied along with P2O5 @ 80 kg ha-1 as single super phosphate (SSP), borax @ 10 kg ha-1 and zinc sulphate @ 10 kg ha-1 in all the treatments. The result revealed that increasing fertigation level increased nutritional status. Greater amount of protein, sugar, starch and mineral nutrient yields were noticed in the treatment T6 followed by T5 during both the years of study. The system productivity and water use efficiency were also greater in treatment T6. However the difference between T6 and T5 was negligible during both the years of study. Thus, the treatment fertigation of N-K2O @ 120-120 kg ha-1 (T5) was found optimum for elephant foot yam+green gram intercropping system.
