ThesisItem Open Access Morpho-Physio-Biochemical and Molecular Characterization of Different Genotypes of Ber (Ziziphus mauritiana Lamk.)(COLLEGE OF AGRICULTURE SWAMI KESHWANAND RAJASTHAN AGRICULTURAL UNIVERSITY, BIKANER- 334006, 2022) Vishal Thakur; Susheel KumarIndian ber (Ziziphus mauritiana Lamk.) is one of the ancient fruit of India. Indian jujube or Indian ber belongs to the family Rhamnaceae and its chromosome number is 2n = 48. It is also considered as the king of arid zone fruits. The Ziziphus genus includes about 135 to 170 species (Islam and Simmons, 2006), and within all of them around 17 are native to India (Pareek, 1983 and Singh et al., 2000). Due to high nutritional and different medicinal properties of the fruit and low cost cultivation, it is also considered as poor man‟s fruit (Gajbhiye et al., 2003). Ber fruit crop is one of the most hardy fruit crop extensively grown in arid and semi-arid regions of India. It can also be grown successfully in marginal ecosystems of sub-tropics and tropics (Pareek, 2001). Due to its deep tap root system, the tree responds well to a large number of soils. Since, the cultivation of ber required least care among other fruits plants; the ber trees are suitable to rehabilitate extensive resource poor areas. Different xerophytic properties of ber are tap root system, presence of scales on buds and deciduous behaviour in summer, has made it possible to cultivate successfully in those areas where no other fruit crop do well (Pareek et al., 2007). Therefore, it is also popularly called as „Desert Apple‟.ThesisItem Open Access NUTRITIONAL STATUS OF POTATO (Solanum tuberosum L.) IN LAHAUL VALLEY OF HIMACHAL PRADESH(UHF,NAUNI, 2023-11-26) Vishal Thakur; R S SpehiaThe present investigation entitled “Nutritional Status of Potato (Solanum tuberosum L.) in Lahaul valley of Himachal Pradesh’’ was carried out during 2022-2023 in Lahaul and Spiti district of Himachal Pradesh with the objective to evaluate the soil quality and plant nutrient content under natural and conventional farming practice and work out the relationship between soil nutrient status and plant nutrient contents. A preliminary survey of district Lahaul was conducted and three panchayats were identified for soil and plant sampling. 30 representative surface soil samples along with plant samples (5 each of conventional and natural farming system from each panchayat) from same site were collected and analyzed. Potato growing soils of Lahaul and Spiti district under conventional farming system had significantly higher available primary and secondary nutrients as well as micronutrients compared to the natural farming system. The soil N, P, K, Ca, Mg and S were recorded 5%, 10.5%, 7%, 6%, 13% and 7.4%, respectively, higher under conventional farming as compared to natural farming system. Similarly, micronutrients viz. Zn, Fe, Cu and Mg were recorded 13.4%, 4%, 9.4% and 14%, higher, respectively under conventional farming system as compared to natural farming system. However, organic carbon was recorded 30.5% higher under natural as compared to conventional farming system. Viable microbial count (62.17×105 cfu g-1 bacteria, 11.54×103 cfu g-1 Fungi and 27.92×103 cfu g-1 Actinomycetes) were also recorded higher under natural compared to conventional farming system, which indicating improved soil biological properties under natural farming. Further, conventional farming system recorded higher macro as well as micronutrients in leaf and tuber compared to the natural farming system. Consequently, yield of potato was significantly higher (230.00 q ha-1) under conventional farming system as compared to natural farming (200.02 q ha-1) but natural farming system appears to have an economic advantage over conventional farming system.
