Abstract:A field experiment entitled “Effect of soil and foliar application of zinc sulphate and ferrous sulphate on growth and yield of sunflower (
Helianthus annus L.)” was conducted during
Rabi season of 2020-21 at the Experimental Farm, Department of Agronomy, College of Agriculture, Latur. The soil was clayey in texture and alkaline in reaction. The experiment was laid out in a randomized block design with ten treatments and three replications. The treatments were T
1 -RDF, T
2 -RDF + FYM @ 5 t ha
‑1, T
3 -T
2 + ZnSO
4 @ 20 kg ha
‑1 soil application, T
4 -T
2 + FeSO
4 @ 20 kg ha
‑1 soil application, T
5 -T
2 + ZnSO
4 @ 0.5% foliar spray, T
6 -T
2 + FeSO
4 @ 0.5 % foliar spray, T
7 -T
2 + FeSO
4 @ 20 kg ha

4 @ 20 kg ha
‑1 soil application, T
8 -T
2 + FeSO
4 + ZnSO
4 @ 0.5% foliar spray, T
9 -T
2 + ZnSO
4 @ 20 kg ha
-1 soil application+ FeSO
4 @ 0.5% foliar spray and T
10 -T
2 + FeSO
4 @ 20 kg ha
‑1 soil application + ZnSO
4 @ 0.5% foliar spray. The gross and net plot size was 5.4 m x 4.5 m and 4.2 m x 3.9 m, respectively.
The result revealed that the application of RDF + FYM @ 5 t ha-1 + ZnSO4 @ 20 kg ha-1 soil application and of FeSO4 @ 0.5 % foliar spray (T9) recorded higher growth attributes, yield attributes, seed yield (1768 kg ha-1) and stalk yield (3499 kg ha-1) of sunflower. It was followed by the application of T2 + ZnSO4 @ 20 kg ha-1 + FeSO4 @ 20 kg ha-1 soil application (T7) and T2 + FeSO4 @ 20 kg ha-1 soil application and of ZnSO4 @ 0.5 % foliar spray (T10) and significantly superior over rest of the treatments.
