RESUMEN
During the Rabi season in 2022-2023, a comprehensive trial was carried out at the Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya. Employing a Randomized Completely Block Design (RCBD), the research assessed twelve different interventions, consisting of biofertilizers, GA3, humic acid and a reference group. Notably, the combined application of Azotobacter, Azospirillum, GA3 and humic acid (T10) showcased substantial improvements in several growth parameters. These encompassed plant height (62.23 cm), number of leaves (10.18), length of leaves (54.08 cm), leaf area (624.65 cm²), leaf area index (4.16) and leaf diameter (8.14 mm). Additionally, this treatment recorded the highest Total Soluble Solids (TSS) at 12.37 °Brix. Moreover, the inclusion of sulphur and humic acid significantly affected the pyruvic acid content, with T10 recorded the highest pyruvate values (5.28 µmol/g). Conversely, the reference group (T12) only recorded slight improvements, emphasizing the noteworthy impact of the interventions on both the growth and qualitative characteristics of the onions.
RESUMEN
A research experiment was conducted at vegetable research Complex, Maharajpur, Department of Horticulture, College of Agriculture, JNKVV Jabalpur. The experiment was done to study the effect of sulphur and salicylic acid on Yamuna safed -2 variety of Garlic. The growth, yield, and quality of garlic can be influenced by various factors, including nutrient availability and plant growth regulators like salicylic acid. Sulphur is an essential nutrient for plant growth and plays a crucial role in the development of garlic plants. The experiment was conducted in Randomized Block Design with combination of different concentrations of sulphur (0 kg/ha, 30 kg/ha and 45 Kg/ha) and salicylic acid (60 ppm and 120 ppm). Growth parameters like plant height, number of leaves and pseudostem diameter were found maximum in treatment T-9 (sulphur 45kg/ha and SA 120ppm). Yield parameters like average bulb weight (22.27 gm), Polar diameter (4.41 cm) and Equatorial diameter (3.79 cm) average weight of 10 cloves (9.10 gm), Total soluble solids and Pyruvic acid were also maximum in T-9 (Sulphur 45kg/ha and SA 120 ppm) (42.30 oBrix and 66.09 µmol/gm respectively). From the above findings it can be concluded that for garlic plant the best doses for salicylic acid and sulphur were found to be 120 ppm and 45 kg/ha. Also with graded levels of salicylic acid and sulphur various parameters increased effecttively.
