ThesisItem Open Access Anti-Oxidant Defence Mechanism And Ethylene Evolution In Cajanus Cajan L. Under Drought(Chaudhary Charan Singh Haryana Agricultural University;Hisar, 2000) Jain, Monika; Nandwal, A. S.ThesisItem Open Access Development of technologies for improvement of yield and lawsone content of Henna (Lawsonia inermis L.)"(MPUAT, Udaipur, 2008) Jain, Monika; Rawat, T. S.The present investigation entitled, "Development of technologies for improvement of yield and lawsone content of Henna (Lawsonia inermis L.)" was conducted during two consecutive years viz. 2004-05 and 2005-06 at the Horticulture Farm, Rajasthan College of Agriculture, Udaipur. Three seperate experiments were conducted during the course of the investigation. In the first experiment, effect of nitrogen and phosphorus on yield and lawsone content of henna was studied, where four levels of nitrogen (0, 25, 50 and 75 kg/ha), three levels of phosphorus (0, 25 and 50 kg/ha) and their combination were evaluated. The experiment consisted of 12 treatment combinations, which were replicated thrice and laid out in "Factorial Randomized Block Design". The results indicate that application of 75 kg N and 50 kg P/ha recorded the maximum weight of fresh leaves (325.99 g/plant) weight of dry leaves (98.54 g/plant), weight of henna powder (94.97 g/plant) and lawsone content (2.28 per cent). As well as the highest net return (Rs. 38,622/ha) and B:C ratio (2.58) was obtained in the above mentioned treatment. * Research Scholar, Department of Horticulture, Rajasthan College of Agriculture, Udaipur (Rajasthan) ** Associate Professor, Department of Horticulture, Rajasthan College of Agriculture, Udaipur (Rajasthan) In the second experiment, effect of harvesting time on yield and lawsone content of henna was studied. In this experiment, 4 harvesting treatments (harvesting 2, 3, 4 and 5 months after pruning) were evaluated. The experiment was replicated six times and laid out in "Randomised Block Design". The results indicate that harvesting henna plant 4 months after pruning resulted into highest weight of fresh leaves (188.16 g/plant) weight of dry leaves (56.00 g/plant) weight of henna powder (53.05 g/plant) and lawsone content (2.16 per cent). Similarly, this treatment also exhibited the maximum net return (Rs. 24,540/ha) and B:C ratio (1.89). Further, in the third experiment, effect of different drying methods on lawsone content of henna leaves was examined. In this experiment four drying methods (sun drying, shade drying, oven drying and solar drying) were tested. The experiment consisted of 4 drying treatments which were replicated six times and laid out in "Completely Randomized Block Design". The results indicate that drying of the fresh henna leaves in shade exhibited the superior recovery (37.5 per cent), minimum moisture (62.5 per cent) and lawsone content (2.15 per cent). Same treatment gave the highest maximum net return (Rs. 610/q) and B:C ratio (4.36).ThesisItem Open Access Development of technologies for Improvement of Yield and Lawsone Content of Henna (Lawsonia inermis L.)(Department of Horticulture, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur, 2008) Jain, Monika; Rawat, T.
