Zinc is an essential micronutrient required for the optimum growth and development of plants. It plays a crucial role in plant metabolism and functions, and its deficiency can lead to various growth abnormalities. Paddy nursery, in particular, is prone to zinc deficiency due to its high alkaline and calcareous nature. Here are some information on how to control zinc deficiency in Paddy nursery.
1. Soil Testing: One of the most crucial aspects of controlling zinc deficiency in paddy nursery is soil testing. Soil testing will help determine the level of zinc present in the soil, allowing the farmer to apply appropriate measures if there is a deficiency. It is advisable to conduct soil testing before planting the crop to determine the zinc level and to apply appropriate measures.
2. Application of Zinc Fertilizers: In cases where soil testing has identified zinc deficiency, the application of zinc fertilizers is essential. Zinc fertilizers can be applied to the soil as basal or foliar applications. Basal application involves applying zinc fertilizers at the time of sowing or transplanting, while foliar application involves spraying zinc fertilizers on the leaves. Foliar applications are preferable as they are more efficient in correcting zinc deficiencies.
3. Use of Zinc-Enriched Composts: The use of compost enriched with zinc can help improve the zinc level in the soil. To prepare zinc-enriched compost, mix the organic waste material with the zinc-rich fertilizer. This will ensure that the compost is enriched with sufficient amounts of zinc, which will be available for the plants’ uptake.
4. Crop Rotation: Crop rotation is an effective method of controlling zinc deficiency in paddy nurseries. Planting legumes such as soybeans, lentils, and peanuts, which are known to fix atmospheric nitrogen, can help improve soil fertility and reduce soil acidity.
5. Application of Soil Acidity Correctors: Paddy nurseries are often characterized by high alkalinity and calcareous soil conditions that can affect micronutrient absorption, including zinc. Applying soil acidity correctors such as sulfur, lime, and gypsum can help reduce soil pH and increase zinc uptake. This should be done with caution to avoid over-acidifying the soil.
In summary, controlling zinc deficiency in paddy nursery involves a combination of methods such as soil testing, application of zinc fertilizers, use of zinc-enriched compost, crop rotation, and application of soil acidity correctors. Implementing these measures will promote optimum growth and development of paddy plants and improve overall crop yields.
