Abstract:
A field experiment was conducted at research farm, department of forestry, jnkvv, Jabalpur during rabi season 2020-21 to find out nutrient uptake of mustard crop in different fertilizer levels under Gmelina arborea and Dalbergia sissoo based agroforestry systems. The experiment was laid out in a factorial randomized block design (FRBD) with 4 replications and 2 factor and 3 fertilizer treatments consisted of F₁ (75%NPK@ 45:30:30 kg ha^-1), F₂ (100%NPK@ 60:40:40 kg ha^-1), and F₃ (125%NPK@ 75:50:50 kg ha^-1) the nutrient absorption by mustard crop under different fertilizer levels. The result revealed that there were different variations in nutrients uptake by mustard. The highest nutrient absorption by mustard seed was observed in F₃ (9.20:0.858:8.91) and minimum was in F₁ (5.16:0.352:3.97). The highest nutrient absorption by straw was observed in F₃ (4.64:0.122:24.49) and minimum was in F₁ (3.07:0.084:19.36). among different factor under fertilizer level was different estimated in mustard grain under Gmelina was estimated maximum was found in F₃ (11.34:1.133:10.33) and minimum was in F₁ (6.01:0.513:4.56) whereas under fertilizer level was different estimated in mustard straw under Gmelina was estimated maximum was found in F₃ (4.99:0.130:24.09) and minimum was in F₁ (3.52:0.096:20.69) moreover mustard grain under Dalbergia was estimated maximum was found in F₃ (7.06:0.583:7.49) and minimum was in F₁ (4.30:0.191:3.39) whereas under fertilizer level was different estimated in mustard straw under Gmelina was estimated maximum was found in F₃ (4.29:0.113:18.03) and minimum was in F₁ (2.65:0.072:24.90).
