Background: Indian bean is established as a prime vegetable crop in India and it attracts a huge market in its seasonal time period due to its multiple uses. Using of organic liquid fertilizer is demand of recent era. Concept of application of organics is vegetable crops is recent trend as it improves yield and helps to extent growth without any adverse effects on ecosystem.

Methods: In this experiment, two organic based nutrient formulations viz. Novel organic liquid nutrient and Novel Plus organic liquid nutrient were applied as a foliar spray at 30 days after sowing and 60 days after sowing on Indian bean variety Gujarat Navsari Indian Bean 22 and evaluated its effects on different growth parameters and yield parameters. The experiment was arrayed with Randomized Block Design having three replications and seven treatments i.e., No spray (T₁), 0.5 % Novel organic liquid nutrient (T₂), 1.0 % Novel organic liquid nutrient (T₃), 1.5 % Novel organic liquid nutrient (T₄), 0.5 % Novel Plus organic liquid nutrient (T₅), 1.0 % Novel Plus organic liquid nutrient (T₆) and 1.5 % Novel Plus organic liquid nutrient (T₇).

Result: Treatment T₆ executed maximum plant height and highest number of branches. Maximum fresh weight (30.87 g per plant) and dry weight (8.01 g per plant) were also registered under the same treatment T₆. Similar treatment has proved to be superior for acquiring highest pod weight, maximum number of pods per plant, pod yield per plant and pod yield per individual plot. In terms of apex total pod yield per plot (3,641 g) and pod yield per hectare (5,619 kg) treatment T₆ have performed the best as well. Predominantly, application of 1.0 % Novel Plus organic liquid nutrient on Indian bean [Lablab purpureus (L.) Sweet] as a foliar spray had positive effects in aspects of growth as well as yield parameters.
