SHARMA, RAJINDERKULDEEP SINGH2023-07-172023-07-172023-06https://krishikosh.egranth.ac.in/handle/1/5810198295ABSTRACT The present investigation titled, “Effect of foliar application of kinetin on growth, leaf yield, seed yield and quality attributes in fenugreek” was carried out on cv. Pusa Early Bunching. Field trial was laid out in Randomized Complete Block Design (Factorial) with three replications of each treatment combination at Pandah Experimental Farm of the Department of Seed Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi 2021-22. The treatments comprised of three stages of application viz. S1 (45 DAS), S2 (60 DAS) and S3 (75 DAS) and three kinetin doses (D) i.e., D1 (25 ppm), D2 (50 ppm) and D3 (75 ppm), thus, making nine treatment combinations along with control. Observations were recorded on different aspects of growth, seed yield and quality. From the present study, it was concluded that treatment combination D3S1 (6-BA @ 75 ppm 45 DAS) was highly significant recording minimum days ( 82.00) to first leaf cut after sowing, maxima for branches plant-1 (8.03), leaf yield at first cut (0.807 kg plot-1) and total leaf yield (1.71 kg plot-1 and 84.41q ha-1), minimum days to 50 % flowering (105.67), maximum values for plant height (47.24 cm) at harvesting stage, pods plant -1 (24.04 ), pod length ( 10.36cm), number of seeds pod-1 ( 13.06), weight of 25 pods (7.35g), seed yield (0.24 kg plot-1 and 11.85q ha-1), test weight (11.31g), nodules plant-1 (4.84 ) after pod harvest, dry matter (15.11g) plant-1, harvest index (29.05%) and biological yield ( 40.78q ha-1). Under laboratory conditions, maxima were recorded for germination of harvested seed (94.18%), seedling length (23.37cm), seedling dry weight (43.63 mg), seed vigour index-I (2200.75), seed vigour index-II (4108.91 and minimum seed electrical conductivity (0.086 dS m-1) assessed using CRD being significantly superior over all other treatment combinations. This treatment combination also ensured highest B: C ratio (3.74: 1) for leaf and (0.74: 1) for seed production. Hence, treatment combination D3S1 (6-BA @ 75 ppm 45 DAS) can be recommended for production of green leaves and higher yield of quality seed after multi-location testing under mid-hill conditions of Himachal Pradesh.EnglishThesis
