Field experiment was conducted during rabi season of 2016-17 to investigate zero tilled cowpea (Vigna unguiculata L.) grown with various inputs under Konkan condition. The treatments comprised of absolute control (T1), weed control (T2), T2 + recommended dose of fertilizers (RDF; 25:60:40 kg N:P:K ha ) (T3), T3 + bio-fertilizers (T4), T4 + micronutrients (T5), T5 + plant protection (T6), T6 + paclobutrazol (T7), T7 + one irrigation at pod filling stage (T8). The treatment T8 was found significantly superior for all the growth parameters, yield attributing characters, protein content, grain and straw yield followed by treatment T7. However both the treatments remained statistically at par with each other, but found significantly superior over rest of the treatments. The significantly lowest grain and straw yield was recorded by treatment T1 (absolute control) where no input was given to crop. Increase in grain yield due to treatments T2, T3, T4, T5, T6, T7 and T8 over treatments T1 was to the tune of 48.44, 64.20, 67.27, 71.09, 76.43, 76.84 and 82.26 per cent, respectively.
