WITH RESPECT TO TREE GROWTH CHARACTERS(College of Horticulture and Forestry, Jhalawar, 2022) NILESH TAILOR; Prahlad V.C.A field experiment entitled “Characterization of aerial roots of Ficus benghalensis Linn. with respect to tree growth characters” was carried out during the year 2021-2022 by selecting total 80 numbers of trees from 4 size of diameter classes D1 (<30cm), D2 (30-60cm), D3 (60-90) and D4 (>90cm) from Jhalawar locations. The vital tree growth characters, characterization of aerial root forming trees and their soil character were studied as part the investigation. The open grown trees in absence of neighbour competition utilized unlimited light and space, resulted in wider crown spread, lesser crown height branched profusely to provide stability and mechanical strength. The higher slenderness index of D1 and D2 class indicates decreased stability there by more vulnerable to damage in comparison to big trees which intern seems to be producing aerial roots in initial period itself for their survival that persisted in subsequent diameter classes. Though aerial roots formation reported both from primary and secondary branches but 98% of primary and secondary branches reported to form aerial roots in D4 class while 85% and 88% in primary and secondary branches respectively from D2 class. Further, 38% of buttress root formation in our study that too 45% each in D3 and D4 class has also expressed an explicit interrelation with aerial root formation. A strong correlation exists between cluster distance, base height of aerial roots with trees and crown size where minimum 41.59 to maximum 146.15 aerial root cluster per trees were reported to spread distance from 0.16m to 8.09m from the centre of the stem axis. Also, the base height of aerial roots in taller trees (D4 class) begin to cling above ground from minimum 3.11m to 6.75m compared to trees of lesser height (D2 class) that found clinging from 2.07m to 3.83m. Regarding the gap length of aerial roots, the bigger trees reported to produce longer aerial roots just short of 3.86m (D1 class) to 1.03m (D3 class) vertical length to reach the ground. The diameter and moisture % of aerial roots showed positive relation with tree size where the smaller root diameter(5.18mm) reported lesser moisture% (43.15%) compared to higher moisture% (47.15%) from higher diameter of aerial root (7.52mm). The soil analysis of current study reported the higher content of available Nitrogen (218.17kg/ha), available Phosphorus (35.18kg/ha), available Potassium. (316.87kg/ha), pH (7.19), EC(0.49dS/m) and bulk density (1.41g/cc) in D1 class. While highest soil moisture (10.01%) and organic carbon (0.6%) found in D4 class. Keywords- Aerial roots, base height, cluster distance, crown projection ratio, gap length, moisture percentage, slenderness index.ThesisItem Open Access ASSESSMENT OF GENETIC VARIABILITY AND PERFORMANCE OF ISABGOL (Plantago ovata Forsk.) GENOTYPE IN SOUTH-EAST REGION OF RAJASTHAN(College of Horticulture and Forestry, Jhalawar, 2022) RAM LAKHAN DHAKAR; Dr. Bhuvnesh NagarGenetic variability, correlation and path analysis were studied in a set of 14 genotypes of Isabgol grown in a randomized block design with three replications at the College of Horticulture and Forestry, Jhalawar during Rabi season of 2021-22. Analysis of variance revealed significant genotypic differences for all the characters under study. Highly significant differences among the genotypes for all the characters indicate that variation among the genotypes is heritable. The genotype Jawahar recorded maximum seed yield per plant (5.95 g) and also the performance of this genotype was better for other yield attributes characters. The genotypes Mayuri (5.81 g), PB-6-3 (5.04 g) and Niharika (4.35 g) recorded higher seed yield per plant. Phenotypic coefficient of variation is higher than genotypic coefficient of variation for all the characters under study, so it could be concluded that phenotypic selection would be more effective. The character association studies indicated that the advantages of upgrading Isabgol genotypes through simultaneous selection for plant height at maturity, number of tillers per plant, number of spikes per plant, number of seeds per spike, husk content per plant percent, husk content per plant and swelling index. The data pertaining to path coefficient revealed that husk content per plant (g), days to 50% flowering, swelling index and seed moisture indicating that selection should be made on the basis of these traits for improvement in seed yield of Isabgol.ThesisItem Open Access INTERCROPPING FENNEL (Foeniculum vulgare MILL.) UNDER SHISHAM (Dalbergia sissoo ROXB.) BASED AGROFORESTRY SYSTEM IN SOUTH-EASTERN RAJASTHAN(College of Horticulture and Forestry, Jhalawar, 2023) NIKITA KUMARI; Dr. S.B.S PandeyThe present investigations entitled “Intercropping Fennel (Foeniculum vulgare Mill.) under Shisham (Dalbergia sissoo Roxb.) based agroforestry system in South-Eastern Rajasthan.” was laid out in RBD with three replications during September, 2022 to April, 2023 at Herbal Garden, under the Department of Silviculture and Agroforestry, College of Horticulture and Forestry, Jhalawar (Agriculture University, Kota). Four years old Plantations of Shisham (Dalbergia sissoo Roxb.) at 5 m × 5 m spacing were used for intercropping of five varieties of Fennel (Foeniculum vulgare Mill.) viz., AF-1, AF-2, RF-125, RF-205 and RF-290 planted at 50 cm × 20 cm were selected for the present study. The analysis of variance showed significant differences among intercropping Fennel under Shisham based agroforestry system as well as sole cropping system. For the growth and yield of Shisham, it was found non-significant with respect to all the treatments whereas, total chlorophyll content, germination percent was found non- significant in Fennel. Significant maximum plant height of Fennel at different intervals as 30 DAS, 60 DAS and 90 DAS and at harvest was recorded in the T1 (Shisham+ Foeniculum vulgare Mill. var. AF-1) (16.15 cm, 106.42 cm, 157.50 cm and 182.14 cm). The maximum test weight of Fennel wasfound in T1 (Shisham+ Foeniculum vulgare Mill. var. AF-1) (9.95 g) followed by T2 (Shisham+ Foeniculum vulgare Mill. var. AF-2) (9.84 g) were also found significant. The significant maximum seed yield per plant was found in the T1 (Shisham+ Foeniculum vulgare Mill. var. AF-1) (25.64 g) followed byT2 (Shisham+ Foeniculum vulgare Mill. var. AF-2) (25.42 g) and the maximum economical yield (25.64 q/ha) and biological yield (68.92 q/ha) was found in T6 (Foeniculum vulgare Mill. var. AF-1 sole). The highest benefit-cost ratio was found in T1 (Shisham+ Foeniculum vulgare Mill. var. AF-1) (4.83). The maximum growth, yield and biomass of Fennel was found higher under the Agroforestry system than the sole cropping. The T1 and T2 (Shisham + Foeniculum vulgare Mill. var. AF-1, Shisham+ Foeniculum vulgare Mill. var. AF-2) performed better among all five varieties of the Fennel intercropped under Shisham based Agroforestry system. The higher benefit-cost ratio also revealed that AF-1 (Shisham + Foeniculum vulgare Mill. var. AF-1) variety of Fennel may be grown under Shisham based agroforestry system in the Jhalawar climate. Therefore AF-1 among five varieties of Fennel is recommended as an intercrop at the spacing 50 cm × 20 cm in Shisham plantation at the spacing of 5 m × 5 m.ThesisItem Open Access VALUE ADDITION OF AONLA (Emblica officinalis Gaertn.)
