Abstract:
During Rabi period, a field experiment was conducted at a research farm under Department of Forestry JNKVV, Jabalpur season 2021-22 to know the nutrient absorption of the mustard crop with different fertilizer rates under agroforestry systems based on Gmelina arborea and Dalbergia sissoo. The experiment was structured factorial randomized block designs (FRBD) with 4 replicates and 2 factor treatments and 3 fertilizers passed F₁ (75% NPK at 45:30:30 kg ha^-1), F₂ (100% NPK at 60:40:40 kg ha^-1) and F₃ (125% NPK at 75:50:50 kg ha^-1) Nutrient absorption through mustard cultivation with different fertilizers. The result augmented that there were different variations in nutrients utilization by mustard. The highest nutrient content (N: P: K) by mustard seed was found in F₃ (2.93:0.30:3.53) and minimum was in F₁ (2.48:0.17:2.11) moreover nutrient absorption by straw was observed in highest F₃ (0.28:0.008:7.58) and minimum was in F₁ (0.23:0.007:4.56). The mustard seed nutrient content on factor Gmelina arborea (2.69:0.29:2.90) was higher than Dalbergia Sissoo (2.39:0.16:2.71). Nutrient uptake (N:P:K @ Kg ha^-1) in mustard seed estimated that F₃ (14.42:1.522:17.35) was highest and minimum in F₁ (7.00:0.559:6.42) whereas under fertilizer level was different in mustard straw F₃ (9.36:0.281:45.60) and minimum was in F₁ (5.94:0.186:35.02) moreover mustard grain on factor Gmelina arborea (11.82:1.285:12.92) was estimated maximum and minimum was estimated in Dalbergia sissoo (7:95:0.564:9.27).
