ThesisItem Open Access SEED TECHNOLOGICAL INVESTIGATIONS FOR TUBER PRODUCTION IN POTATO {Solanum tuberosum L.)(University of Agricultural Sciences GKVK, Banglore, 2007-01-03) VINOD, KUMAR; B. S. VYAKARANAHALAgricultural Research Station, University of Agricultural Sciences, Dharwad dunng kharif 2003 and 2004 to study the effect of seed tuber sise, haulm cu tmg, mtra row spacing, nutrient levels, growth retardants and its methods of application besides micronutrient application and mulching on growth and yield of potato Cv, Kufri Pukhraj and Kufri Jyoti. The results indicated that among the varieties, Kufri Pukhraj was aignincantly superior (19.74 t ha-, over Kufri Jyoti (18.74 t ha-) studied under Northern Transitional Zone of Karnataka. The per plant (338.18 g) and per ha (17.94.t) tuber yield was more with medium size (31-40 g) seed tuber followed by 41-50 g (337.28 g and 17.83 t) and >50 g size seed tuber (333.11 g and 17.58 t). Seed tuber treatment with ZnSOr (0.05 %) recorded maximum total number (8.42) of tubers per plant and total tuber yield (20.62 t) per ha compared to CuSO, (0.05 %) and MgS04 (0.05 %). The closer intra row spacing of 5 cm recorded higher total number of tubers per plant (7.89) and total tuber yield per ha (23,40 t). Further, it was found that the paddy straw mulch performed better (19.97 t ha->) compared to polythene (19,12 t ha-) and no mulch (18.64 t ha-i) treatments.ThesisItem Open Access STUDIES ON MATURITY INDICES AND PRE-SOWING TREATMENTS OF CHILGOZA PINE (Pinus gerardiana Wall.)(UHF,NAUNI,SOLAN, 2011) VINOD, KUMAR; SHAMET, G.S.ABSTRACT The present investigation entitled “Studies on maturity indices and pre-sowing treatment of chilogoza pine (Pinus gerardiana Wall.) was undertaken in the Department of Silviculture and Agroforestry, Dr. Y.S. Parmar University of Horticuture and Forestry, Nauni-Solan 173230 (HP) and Regional Horticulture Research Station Sharbo, Peo district Kinnaur during 2010-2011. The study involved two experiments in all. In experiment-I, for determining maturity indices the seeds were collected from three diameter classes (30-40cm, 40-50cm and 50-60cm) at two week interval starting from 23rd August to 18th October (5 collection dates). Cones and seeds extracted during each collection were subjected to various physico-chemical analysis and germination studies. For optimum maturity, the cones should be collected on 4th October when these are greyed orange in colour and cone and seed moisture contents are 43.09 per cent and 27.90 per cent, respectively. At this stage, the seeds exhibited maximum viability (82.67%), germination (73.23%), germination capacity (78.45%), germination energy (46.20%) and germination value (3.11). During this collection, the seeds were found to have 96.27mg/g total sugar, 20.20mg/g reducing sugar, 72.27mg/g non-reducing sugar, 36.62mg/g total phenol and 49.17 per cent oil content. Similarly, diameter class 30-40cm was observed to have maximum germination (53.00%), germination capacity (59.91%), germination energy (29.27%) and germination value (1.84). The experiment-II, dealt with pre-sowing seed treatments of chilgoza seed using ten different growth regulators and salt solutions and two different soaking periods. Application of 100ppm GA3 was found to result in maximum germination (60.83%), germination capacity (68.33%), germination energy (44.17%), germination value (0.34) and germination index (0.17). The 24hr soak resulted in better germination (50.50%) and other germination parameters in chilgoza pine seed.
