Certainly, I can provide an article on control of zinc deficiency in paddy. Here it is:
Zinc deficiency is one of the most common micronutrient deficiencies observed in paddy fields around the world. It is a serious issue because zinc plays a crucial role in several metabolic processes in the plant and its deficiency may lead to a reduction in crop yield and quality. Fortunately, there are several strategies that can be employed to control zinc deficiency in paddy crops.
One of the simplest and most effective ways to control zinc deficiency in paddy crops is through the application of zinc fertilizers. Zinc fertilizers are available in various forms, including zinc sulfate, zinc oxide, and zinc chelates. These fertilizers can be applied to the soil or directly to the plant through foliar sprays. It is important to note that excessive amounts of zinc can be toxic to the plant, so it is important to follow the recommended application rates.
Another approach to control zinc deficiency is to improve soil health. Zinc is more readily available to the plant when the soil pH is neutral to slightly acidic. Therefore, maintaining the optimal pH level is crucial for the uptake and utilization of zinc by the paddy plant. Adding organic matter such as soil amendments, compost, or manure can also help improve soil health and increase the availability of zinc.
Crop rotation is another effective strategy to control zinc deficiency in paddy fields. Growing crops like legumes, which have the ability to fix atmospheric nitrogen, can provide an additional source of zinc to the paddy crop when they decompose. Legumes such as cowpea, soybean, and pigeon pea are excellent choices for crop rotation in paddy fields.
Finally, selecting paddy varieties that are tolerant to zinc deficiency is a proactive measure that can minimize the adverse effects of zinc deficiency. Some paddy varieties have been developed for their ability to tolerate zinc deficiency and perform well even under low zinc conditions. A few examples of such varieties are IR74371-70-1-1, IR68144-2B-2-1, and IR80967-2B-166.
In conclusion, controlling zinc deficiency in paddy crops is crucial for ensuring optimal crop yield and quality. Strategies such as the use of zinc fertilizers, improving soil health, crop rotation, and selection of zinc-tolerant paddy varieties can be effective in managing zinc deficiency in paddy fields. Consultation with a crop specialist and soil testing can help determine the best methods for controlling zinc deficiency in specific paddy fields.
