ThesisItem Open Access COMPARATIVE EVALUATION AND STANDARDIZATION OF MATURITY INDICES FOR PROMISING PLUM (Prunus salicina Lindl.) CULTIVARS IN KULLU VALLEY OF HIMACHAL PRADESH(UHF,NAUNI, 2022-12) THAKUR, SHIVANI; RANA, VISHAL SABSTRACT The present investigation entitled “Comparative evaluation and standardization of maturity indices for promising plum (Prunus salicina Lindl.) cultivars in Kullu valley of Himachal Pradesh” was carried out at the experimental orchard at Regional Horticulture and Training Station, Bajaura, Kullu (HP). The experiment was laid out on 10-12 years old uniform plants of different plum cultivars according to Randomized Block Design (RBD). The entire program of study was categorized into three experiments with a view to study pattern of fruit growth, comparative performance and standardization of harvest maturity for promising plum cultivars. It was revealed that plum cultivars followed a double sigmoidal growth pattern which can be divided into three distinct phases, viz; Phase-I representing with rapid growth (20-60 DAFS), Phase –II of slow growth (60-80 DAFS), and phase –III indicating a period of final swell and faster growth, followed by a depressed growth till ripening which varied according to different cultivars. On the basis of two year observations the cultivars Satluj Purple and Red Beaut were categorized as early; Santa Rosa, Black Amber and Mariposa as mid; Friar, Frontier and Shiro as late blooming cultivars. Furthermore, the optimum harvest dates cultivars for Black Amber and Mariposa was noted at 120 DFFB, Friar at 116 DFFB, Santa Rosa at 104 DFFB , Frontier at 103 DFFB, Shiro at 96 DFFB and Red Beaut at 94 DFFB. On these harvest dates the fruits of these cultivars attained the best possible physico-chemical characters including sensory appeal. Among different maturity indices fruit colour, DFFB, TSS and sugar acid ratio were found to be the reliable maturity indices for the harvesting of plum.ThesisItem Open Access EFFECT OF GIRDLING ON YIELD AND QUALITY OF KIWIFRUIT (Actinidia deliciosa Chev.) RAISED THROUGH DIFFERENT PROPAGATION METHODS(UHF,NAUNI) SAMAREDDIN; RANA, VISHAL SABSTRACT The present investigation entitled “Effect of girdling on yield and quality of kiwifruit (Actinidia deliciosa Chev.) raised through different propagation methods” was carried out during 2019-20 in the experimental block of Department of Fruit Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni-Solan, Himachal Pradesh. Ten years old vines of uniform size and vigour, planted at 4.0 m × 6.0 m spacing were selected for the study. The experiment was laid out according to Randomized Block Design (RBD), comprising of twelve treatment combinations with three replications per treatment. The experimental plants were raised through three different modes of propagation viz., in situ, grafting and own rooted (cuttings) which were planted in different sections of experimental orchard. Four different girdling levels namely; full (100% girdling), 1/2 (50% girdling), 1/4 (25% girdling) and no girdling were applied to the experimental vines. On the basis of results obtained in the present investigation, it was concluded that the grafted kiwifruit vines girdled upto 1/4 (25%) trunk girth by removing 2 mm bark in the last week of March exhibited best performance in terms of improvement in flower and yield parameters namely; number of flowers per shoot, per cent fruit set, number of fruits per shoot, total yield and graded yield. Furthermore, the before mentioned treatment also resulted in better quality parameters like fruit size, fruit weight, total soluble solids, ascorbic acid, sugars contents and sugar acid ratio. The vines subjected to this treatment also enhanced the shoot and leaf carbohydrates contents. However, the ungirdled own rooted vines exhibited highest contents of macronutrients and vegetative growth parameters like leaf area index and number of shoots per cane.ThesisItem Open Access EFFECT OF TIME AND LEVEL OF SUMMER PRUNING ON THE VINE CHARACTERISTICS, FRUIT YIELD AND QUALITY OF KIWIFRUIT CV.

YASHWANT SINGH PARMAR UNIVERSITY OF HORTICULTURE AND FORESTRY, 2007) BASAR, JUMMAR; RANA, VISHAL SThesisItem Open Access EVALUATION OF HARDWOOD AND SEMI-HARDWOOD CUTTINGS FOR ROOTING PERFORMANCE IN EXOTIC CULTIVARS OF KIWIFRUIT (Actinidia spp.)(NAUNI,UHF, 2020-08) CHOUDHARY, SONALI; RANA, VISHAL SABSTRACT The present study entitled, “Evaluation of hardwood and semi-hardwood cuttings for rooting performance in exotic cultivars of kiwifruit (Actinidia spp.)” was carried out during 2019-2020 in the Department of Fruit Science, Dr. YS Parmar University of Horticulture and Forestry at Nauni, Solan (HP). The experiment comprised of eight exotic cultivars as treatment and the research trial was laid out according to Randomized Block Design (RBD). The entire programme of study was conducted under two experiments with a view to elucidate the comparative rooting performance of hardwood and semi-hardwood cuttings in exotic cultivars of kiwifruit. Eight exotic cultivars namely; Anna, Chung Bai, Cordifolia, Issai Kiwi, Kens Red, Meader Male, MSU Klur and 74-49 which were taken as treatment. Each treatment was replicated thrice with 30 cuttings per cultivar. The cuttings for experiment-Iwere taken in mid-January (hardwood cutting) and for experiment-II were taken in mid-July (semi-hardwood cutting). Among different cultivars, Kens Red exhibited best performance in term of root, shoot and leaf characteristics. The cultivar Anna performed least on the basis of aforesaid parameters. The survival percentage after field transplanting was also found highest in Kens Red cultivar, whereas, it was recorded minimum in Anna cultivar. Among different cutting types, semi-hardwood cuttings of different cultivars performed better as compared to hardwood cuttings with respect to parameters like per cent rooted cutting, number of primary roots, number of secondary roots and the survival percentage. However, hardwood cuttings performed better in respect of shoot and leaf characteristics. The information generated on the propagation of these new exotic kiwiberry cultivars will serve as a basis for theresearchers in developingnew rootstocks for quality production ofplants.ThesisItem Open Access INFLUENCE OF SEAWEED EXTRACT ON GROWTH, YIELD AND QUALITY OF STRAWBERRY (Fragaria × ananassa Duch.)

Ferguson](UHF,NAUNI, 2019-11) SHARMA, VARSHA; RANA, VISHAL SABSTRACT The present investigation entitled “Influence of seaweed extract on growth, yield and quality of kiwifruit [Actinidia deliciosa (A. Chev.) C.F. Liang & A.R. Ferguson]” was carried out in kiwifruit block of Department of Fruit Science during the year 2018. Nine years old kiwivines cv. Allsion of uniform size and vigour, planted at 4m × 6m spacing were selected for studies. The experiment was laid out in Randomized Block Design with 11 treatments viz; T1 (SWE Spray @ 1000 ppm at FS), T2(SWE Spray @ 2000 ppm SWE at FS), T3(SWE Spray @ 3000 ppm at FS), T4(SWE Spray @ 1000 ppm at FS and 10 DAFS), T5(SWE Spray @ 2000 ppm at FS and 10 DAFS), T6(SWE Spray @ 3000 ppm at FS and 10 DAFS), T7(SWE dip @ 1000 ppm 10 DAFS),T8(SWE dip @ 2000 ppm 10 DAFS),T9(SWE dip @ 3000 ppm 10 DAFS),T10(CPPU dip @ 5 ppm 10 DAFS) and T11 [Control (Untreated)]. The present investigation compared different seaweed extract treatments, applied at different time and concentration with CPPU and untreated control. The highest increase in fruit length and fruit diameter in developing kiwifruit was recorded with T9(SWE dip @ 3000 ppm 10 DAFS) which was non-significant with CPPU treatment and wassuperior to control. The average fruit length, fruit diameter, average fruit weight, fruit firmness and total fruit yield were also found to be the highest with the same treatment. Fruit quality parameters namely fruit TSS and total sugars were recorded maximum with T6(SWE Spray @ 3000 ppm at FS and 10 DAFS). The TSS:acid ratio and reducing sugars were recorded highest with T9(SWE dip @ 3000 ppm 10 DAFS). The treatment T8 (SWE dip @ 2000 ppm 10 DAFS) was found to advance the harvesting maturity by 6 days and this treatment also exhibited lowest physiological loss in weight (% PLW) with highest ascorbic acid content. After 15 days storage at ambient room temperature (25±2oC), the treatment T9 (SWE dip @ 3000 ppm 10 DAFS) recorded highest TSSacid ratio and the lowest titratable acidity.ThesisItem Open Access STANDARDIZATION OF FERTIGATION SCHEDULE AND BIO-FERTILIZERS ON GROWTH, YIELD AND QUALITY OF KIWIFRUIT (Actinidia deliciosa Chev.) cv. ALLISON(NAUNI,UHF, 2020-12) PAWAR, RAVINA; RANA, VISHAL SABSTRACT The present investigation entitled “Standardization of fertigation schedule and biofertilizers on growth, yield and quality of kiwifruit (Actinidia deliciosa Chev.) cv. Allison” was conducted on 35 years old kiwifruit vines of uniform size and vigour, planted at a spacing of 4.0 m × 6.0 m at experimental block of Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (Himachal Pradesh) during the year 2018 and 2019. The entire programme of study was divided into two experiments. In the first experiment, three fertigation levels viz., 100 per cent, 80per centand 60per centrecommended dose of NPK were applied at three application intervals viz., 7 days , 10 days and 15 days according to Randomized Block Design (Factorial). Accordingly, the fertigation was given in 21, 15 and 10 split doses, respectively. Fertigation with 100 per cent recommended dose of NPK in 15 splits at 10 days interval from the emergence of new flush exhibited better vegetative growth performance and nutrient status of soil and leaf. However, the fertigation with 80 per cent recommended dose of NPK in 15 splits at 10 days interval from the emergence of new flush exhibited better bloomintensity, fruit set, yield and quality characteristics. In the second experiment, three fertigation levels (100 %, 80 % and 60 %) of recommended dose of NPK were applied with Arka Microbial Consortium @ 5 ml L-1(single or two applications) in the month of February prior to the emergence of new flush and in Julyaccording to Randomized Block Design (RBD). Fertigation with 100 per cent recommended dose of NPK coupled with two applications of Arka Microbial Consortium @ 5 ml L-1 in the month of February and in July recorded highest bloom intensity, fruit set along with better leaf and soil nutrient status. However, fertigation with 80 per cent recommended dose of NPK coupled with single or two applications of Arka Microbial Consortium @ 5 ml L-1 resulted better performance in terms of kiwifruit yield, yield efficiency and fruit quality parameters namely; fruit size, fruit weight, total soluble solids, TSS: acid ratio, total sugars and nutrient status of leaf and sThesisItem Open Access STANDARDIZATION OF HARVEST MATURITY FOR LOW CHILL CULTIVARS OF PEACH [Prunus persica (L.)
