ThesisItem Open Access Eco-physiology, Nutritive value and Allelopathic effect of two Bauhinia species on Wheat varieties in Garhwal Himalaya(College of Forestry, Ranichauri Campus , V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2015-08) Yadav, Neeraj; Khanduri, Dr. V. P.The present investigation was carried out during the year 2014-15 in the Research Block of Department of Forestry, V.C.S.G. Uttarakhand University of Horticulture and Forestry, Ranichauri, Tehri Garhwal, Uttarakhand. Seed germination study at diffrent constant temperature, seed storability, seed sown in nursery at diffrent depth, orienation, size and seed coat colour of Bauhinia retusa and Bauhinia variegata were evaluted in Randomized Block Design (RBD). Nutirutive value of both species were also analysed by using RBD. The allelopathy expriements was condected in laboratry by using CRD. The seed germination experiments were conducted with different constrant temperature (250, 200& 150C) and different type of storage container (Plastic cane, cotton bag & Polybag). In these extprements germination percent, radicle and plumule growth was calculaued. Seed were sown in nursery and thier germination percent, mean germination time, germination index and growth chracters and their biomass (i.e. shoot length, collar diameter, number of leaves/plant, root length, shoot dry weight, root dry weight, leaves dry weight, total dry weight and root/shoot dry weight) in field condition were masured. The nutritive value of collected leaves were analysed Total ash, Ether extract, Crude fiber, Crude protein, Nitrogen free extract, Organic matter and Total corbohydrate. In allelopathy expriemnts, diffrent leaves and bark extract concentartion were prepared to evuluate the effects of these extract on diffrent wheat varieties. The result revealed that the optimum and uniform germination of both Bauhinia species was found at 250C constant temperature. The radicle and plumule growth were also recorded maximum at this temperature. Polybags are suitable for the storage of Bauhinia seeds. On an average, large size seed, yellow seed coat colour had given higher germination as well as good growth. Seeds of B. retusa were sown at horizontal position while B variegata were sown at upright position had more germination and produced vigour seedlings. Seeds of both Bauhinia species sown at different depth proclaimed that the seeds of B. retusa had more germination at 4 cm depth while produced teller seedlings at 2cm depth. Seeds of B. variegata were sown at 2 cm depth germinate better and produced vigorous seedling growth as well as biomass. Crude protein was found maximum in month of August and May for B. retusa and B. variegata, respectively. Among the test crops, VL 829 shows more resistance for bark and leaves extract. While bark extracts were more toxic as compared to the leaves extracts.ThesisItem Open Access Response of greengram (Vigna radiata L.) to seed priming under rainfed condition(CCSHAU, Hisar, 2021-09) Yadav, Neeraj; Dadarwal, R. S.The present investigation denominated “Response of greengram (Vigna radiata L.) to seed priming under rainfed condition” was executed at Regional Research Station, Bawal, CCSHAU, Hisar during Kharif, 2020. The experiment was conducted in randomized block design, replicated thrice, having nine treatment combination. For the seed treatment of one ha seed rate, 20 g of priming chemical was applied for individual treatment. Greengram is a drought hardy and short duration kharif annual legume crop. Seedling vigour, consistent germination, early seedling emergence, crop growth and development were all increased by priming chemicals. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying was the best priming method in context of phenology, growth characteristics, yield and yield attributes of greengram. Different priming treatments significantly influenced phenological characteristics of greengram. Minimum days taken to emergence, 50% flowering, pod initiation and physiological maturity were accomplished by seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying has 86.67%, 74.23%, 59.9% and 33.09% higher dry weight per plant than control at 15, 30, 45 DAS and at harvest, respectively. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying had 50.73%, 53.63%, 35.30% and 15.56% higher number of branches/plant, number of pods/plant, number of seeds/pod, pod length and test weight. The N, P and K concentration (%) in seed and straw was not significantly influenced by different priming methods. NPK uptake in seed and straw was significantly swayed by different priming methods. Total NPK uptake in seed and straw was highest through seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying had 15.49%, 15.43% and 10.18% higher uptake of nitrogen, phosphorous and potassium, respectively. Seed yield, straw yield and biological yield had significant proclivity towards different priming treatments. Maximum of all were with seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying which was statistically at par with hydropriming for 8 hours and thus the poor farmers should follow simple water soaking instead of chemical priming. Seed priming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying recorded 10.94%, 9.38% and 9.84%, respectively higher seed yield, straw yield and biological yield than control. Highest gross return was observed through osmopriming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying. Similarly, maximum net return and B:C were attained with osmopriming with KH2PO4 @ 2% for 8 hours and 2 hours sun drying.
