Abstract:
To study the effects of biochar and foliar applied silicon, individually as well as their combine interactions on the nutrient content and uptake in fenugreek cv. PRM-45, a field experiment was conducted at organic farm, Rajasthan College of Agriculture, Udaipur in rabi season of 2020-21. Four levels of biochar (control, 2, 3 and 4 t ha^-1) and four levels of foliar applied silicon (water spray, 1.5, 2.0 and 2.5%) were allocated in the field in factorial randomized block design (FRBD) which were replicated three times. The maximum increase in the nitrogen content (3.03%) and phosphorus content (0.43%) in seed and nitrogen content (1.18%), phosphorus content (0.23%) in haulm were found with 4 t ha^-1 biochar while no significant increase observed with silicon levels. Si content and uptake in seed as well as in haulm were recorded highest with the foliar application of 2.5% silicon. Maximum Si uptake by seed (14.50%) were reported in the plots treated with the combined application of 2 t ha^-1 biochar and 2.5% silicon.
