Abstract:

Foliar application of different levels of seaweed extract and enriched banana psuedostem sap were studied on different varieties of green gram (Vigna radiata) to check the nutrient uptake by the crop and soil properties at certified organic farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari during Rabi season of the year 2015-16. The treatment L₂ A showed significantly higher uptake of N (30.41 and 37.94 kg ha^-1), P (8.29 and 5.45 kg ha^-1), K (42.42 and 12.48 kg ha^-1), Fe (415.30 and 74.31 g ha^-1), Mn (48.96 and 24.57 g ha^-1), Zn (118.54 and 41.89 g ha^-1) and Cu (16.71 and 8.55 g ha^-1) by stover and seed respectively. The minimum value of nutrient uptake by stover and seed recorded in treatment L₆. Among the variety treatment V₁ showed superiority in uptake of N (25.93 and 37.36 kg ha^-1), P (6.41 and 5.55 kg ha^-1), K (34.27 and 12.58 kg ha^-1), Fe (358.92 and 71.08 g ha^-1), Mn (39.52 and 22.05 g ha^-1), Zn (100.13 and 42.71 g ha^-1) and Cu (13.87 and 8.33 g ha^-1) by stover and seed respectively as compared to V₂. Highest total uptake of nutrients by crop also observed in the individual treatment V₁ and L₂. The result revealed that non-significant effect on all the soil property tested due to liquid fertilizer except available N, significantly highest value of available N (201.23 kg ha^-1) linked with both L₂ and L₅ treatment and its minimum value in L₆.
