Effect of Different Micronutrients on the Growth of Turmeric (Curcuma longa L.) cv. Salem

Abstract

The present investigation entitled “Performance of different micronutrients on the growth and yield of turmeric (Curcuma longa L.) cv. Salem produced by pro tray method.” was conducted during the year 2023-2024 at AICRP, on Spices, Asond Block, Central Experimental Station, Wakavali, Dapoli, Dist- Ratnagiri (M.S.), India. The experiment was conducted in randomized block design with nine treatment namely T1: Control (RDF: 200:50:150 kg NPK ha-1), T2: Foliar spray of ZnSO4@ 0.5%, T3: Foliar spray ZnSO4 @ 0.75%, T4: Foliar spray of Borax @ 0.2%, T5: Foliar spray of Borax @ 0.3%, T6: Foliar spray MnSO4 @ 0.25%, T7: Foliar spray of MnSO4 @ 0.5%, T8: Foliar spray of FeSO4 @ 0.3%, T9: Foliar spray of FeSO4@ 0.4% and each treatment was replicated three times. The observations were recorded at 30 days interval at 60, 90, 120 and 150 days after transplanting. The results obtained from the present experiment revealed that application of RDF + Foliar spray of ZnSO4 @ 0.75 % showed overall best results in growth characters at 150 Days after transplanting like Plant height (81.97 cm), leaf length (56.11 cm), leaf width (16.56cm), number of leaves (15.56) and number of tillers (3.5). Thus, from the results obtained, it can be concluded that application of RDF + Foliar Spray of ZnSO4 @ 0.75 % was the most effective for maximizing the growth parameters of turmeric (Curcuma longa L.) under Konkan agro- climatic conditions.
