dc.description.abstractABSTRACT The present investigations entitled “Integrated nutri Hasskent management studies in Eclipta alba (Linn.) Hassk.” were carried out in the experimental field as well as in laboratory of the Department of Forest Products, College of Forestry, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2020-2021. In the first experiment “Morphological studies of Eclipta alba” the plant was found to be herbaceous annual herb. The stem was found to be erect, cylindrical, pubescent, with many branches spreading from the base with distinct nodes and internodes. Leaves were simple, sessile, opposite and whorl at the tip. The plant had thin cymose taproots. Inflorescence was capitulum which comprised of ray florets and disc florets. Involucre bracts were leaf like, enclosing the florets.The flower was solitary or 2- 3 together, white and epipetalous. Pistil was bicarpellary, ovary was inferior and unilocular having one basal ovule. Fruits were found to be achenial cypsella. In the second experiment on Effect of various organic sources and bio-inoculants on germination of seeds of Eclipta alba. Among nine different treatments, the combination of Soil + Vermicompost + Bacillus licheniformis gave early initiation of seed germination (11.00 days), minimum mean days taken to complete the germination (20.33 days), maximum germination (68.67 %), maximum mean daily germination (3.38 %), maximum seedling shoot length (17.83 cm), maximum seedling root length (9.78 cm) and maximum mean seedling biomass (12.70 g). Third experiment on effect of integrated nutrient management on growth and yield of Eclipta alba. The treatment comprised of nine different treatments. Among nine different treatments, vermicompost (N content equivalent to RDF) (4.97 t/ha)+NPK (90:60:30 kg/ha) gave the maximum fresh total biomass yield per plant (175.22 g), dry total biomass yield per plant (48.78 g), estimated fresh total biomass yield per hectare (129.79 q) and estimated dry total biomass yield per hectare (36.14 q). The same treatment recorded highest available N (335.54 kg/ha), P (74.34 kg/ha), K (223.33 kg/ha) and organic carbon (1.30 %) in the soil after crop harvest. “Economic analysis of Eclipta alba” revealed that 50% FYM (7.25 t/ha) +NPK (45:30:15 kg/ha) had the highest benefit: cost ratio of 2.10 which was followed by FYM (N content equivalent to RDF) (14.5 t/ha) + NPK (90:60:30 kg per/ha) with benefit: cost ratio of 2.05.en_US
