ABSTRACT
The present investigation titled, “Effect of different organic mulches on different varieties of edible
Nasturtium for flowering and nutritional characteristics under mid hill conditions of Himachal Pradesh”
was carried out at the Department of Floriculture and Landscape Architecture, Dr YS Parmar University of
Horticulture and Forestry, Nauni, Solan (H.P) during the period November, 2020 to June, 2021. Studies
included two experiments viz., Effect of organic mulches on different varieties of nasturtium for growth,
flowering, seed yield and seed quality characteristics and to study effect of organic mulches for the edible and
nutritional characteristics of different varieties of nasturtium. Both the experiments were laid out in Randomized
Complete Block Design (factorial) for field observations with three replications and Complete Randomized
Design (factorial) for laboratory observations with four replications, comprising four levels of mulches (namely,
spent mushroom compost, pine needles and straw along with control) and five varieties (viz., ‘Empress of India’,
‘Spit Fire Orange’, ‘Alaska Mix Variegated’, ‘Jewel of Africa’ and ‘Gleam Scarlet’). Best results with regards
to plant height (49.81 cm), plant spread (35.43 cm), number of days for first bud appearance (67.11 days),
number of flowers per plant (110.75), leaf area (74.78 cm2), duration of flowering (127.67 days), number of
seeds per plant (280.33), seed yield per plant (47.29 g), seed yield per plot (639.36 g), seed yield per hectare
(5114.85 kg), 100 seed weight (17.03 g), germination percentage (88.25%), seedling length (26.51 cm), seedling
dry weight (22.94 mg), SVI-I (2339.58), SVI-II (2025.15), EC (0.065 dS/m) and ascorbic acid content (73.87
mg/100g) were found in the plants of var. ‘Gleam Scarlet’ mulched with spent mushroom compost. The variety
‘Empress of India’ when grown by mulching the plants with spent mushroom compost (M1) recorded best
results w.r.t. total anthocyanin content (110.40 mg/100g) and DPPH antioxidant activity (81.59 %). However,
TSS (7.90oB) was found to be maximum in var. ‘Empress of India’ when the plants were grown without any
mulch. From the study it is summarized that among the five varieties of nasturtium evaluated, the best
performance was observed in var. ‘Gleam Scarlet’ w.r.t. various characteristics of plant growth, flowering, seed
yield and quality as well and var. ‘Empress of India’ showed better results with regard to edible and nutritional
characteristics. Similarly, the varieties which were grown with spent mushroom compost mulch exhibited better
performance for growth, flowering, seed yield, quality and nutritional characteristics
