A field experiment was conducted during winter season of 2012-13 in sandy loam soil at Central Potato Research Station, Patna to study the effects of seaweed saps on growth, yield and nutrient uptake of Potato. The foliar spray was applied at 45, 60 and 75 days after planting at different concentrations (0, 2.5, 5.0, 7.5 and 10 % v/v) of seaweed extracts namely Kappaphycus( K Sap) and Gracilaria (G Sap). Foliar applications of seaweed sap significantly enhanced large and medium grade as well as total tuber yield. Increment in total tuber yield of potato with application of 7.5% K sap + recommended dose of fertilizer (RDF), 5% G sap + RDF, and 10% G sap + RDF) over control were in tune of 3.95 t ha-1 ,4.88 and 4.07 t ha-1 respectively. Applications of 7.5 % K sap+ RDFand 5% G sap + RDF resulted in increase by 15.8 and 34.9% in large grade tuber yield and 11.5% and 22.5% in medium grade tuber yield, respectively compared to control. Improved nutrient uptake (NPK) was also observed with seaweed extract.

Completely Randomized Design

Background: This study aimed to determine the pattern of N mineralization of tithonia (Tithonia diversifolia) and sugarcane (Saccharum officinarum) leaves and assess the uptake of N nutrients in maize by giving T. diversifolia and S. officinarum leaves with different qualities on sandy loam soil. Methods: The research used a completely randomized design (CRD) with following treatment: T1 (100% T. diversifolia), T2 (100% S. officinarum), T3 (75% T. diversifolia: 25% S. officinarum), T4 (50% S. officinarum: 50% T. diversifolia), T5 (25% T. diversifolia leaves: 75% S. officinarum), T6 (without T. diversifolia and S. officinarum or control). Result: The results showed that the N mineralization pattern of the organic matter combination was significantly higher than the control for all observations. The amount of N mineral released in each treatment was T1 (54.58-529.7 mg/kg), T2 (41.80-381 mg/kg), T3 (47.69-473.6 mg/kg), T4 (46.70-424.0 mg/kg), T5 (70.69-378.9 mg/kg) and T6 (47.14-303.6 9 mg/kg). The sequence of cumulative N release during 12 weeks of incubation was T1 (529 mg/kg) greater than T3 (573.6 mg/kg) greater than T4 (424.0 mg/kg) greater than T2 (381 mg/kg) greater than T5 (378.9 mg/kg) greater than T6 (303.6 mg/kg). These results suggested that T. diversifolia and S. officinarum leaves significantly increased N nutrient uptake in maize by 125% to 144.54%.
