Abstract:
The field experiment was conducted during Kharif 2019 at Experiment farm of Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in a randomized block design with eight treatments and three replications. The treatments were T₁: Control (No any foliar application), T₂: B (0.5%), T₃: Zn (0.5%), T₄: Fe (0.5%), T₅: B (0.5%) + Zn (0.5%), T₆: B (0.5%) + Fe (0.5%), T₇: Zn (0.5%) + Fe (0.5%) and T₈: B (0.5%) + Zn (0.5%) + Fe (0.5%). Application of micronutrients in treatment T₈ i.e. B (0.5%) + Zn (0.5%) + Fe (0.5%) to niger crop recorded significantly higher values in growth attributes like plant height, number of functional leaves, number of branches, leaf area and total dry matter and followed by the treatment T₇ i.e. Zn (0.5%) + Fe (0.5%) at flowering. The lowest values of the above mentioned parameters was recorded with Control (No any foliar application) was applied in (T₁). The effect of different treatments on yield and yield attributing characters viz., number of capsule plant-1, weight of capsule plant-1 (g), weight of seed plant-1, number of seed capsule-1, test weight (1000 seeds), grain, straw, biological yields (kg ha-1) and harvest index were considerably higher with the application of B (0.5%) + Zn (0.5%) + Fe (0.5%) at flowering and capitula formation (T₈) followed by the application of Zn (0.5%) + Fe (0.5%) at flowering (T₇) and the lowest values of the above mentioned parameters was recorded with Control (No any foliar application) was applied in (T₁). On the basis of above findings, it may be inferred that, for getting maximum seed yield application of B (0.5%) + Zn (0.5%) + Fe (0.5%) at flowering and capitula formation was found to be effective in increasing production of niger crop.
