Nutrient management in guar crop is essential for achieving maximum yield and quality of the crop. Guar, also known as cluster bean, is a legume crop that is widely grown in India and other tropical regions for its seed and pod. It is a drought-tolerant crop and can be grown in a variety of soil types. Here is some information on nutrient management in guar crop:
Soil Test and Nutrient Requirement: A soil test is necessary to assess the nutrient status of the soil. Based on the soil test, the nutrient requirement of the guar crop can be determined. Generally, the recommended dose of nutrients for guar crop is 40 kg N, 20 kg P2O5, and 20 kg K2O per hectare.
Organic Manures: Organic manures are an excellent source of plant nutrients. The application of organic manures like farmyard manure, vermicompost, and green manure help to improve soil fertility, texture, moisture-holding capacity, and nutrient availability. They also promote the growth of beneficial microorganisms in the soil.
Mineral Fertilizers: Mineral fertilizers like urea, superphosphate, and muriate of potash are also required to provide the necessary nutrients to the crop. The application of mineral fertilizers should be based on soil test results and the nutrient requirement of the crop.
Fertilizer Application: The fertilizer application should be done at the right time and in the right amounts. The basal application of fertilizers should be done at the time of sowing, and the top dressing should be done at the vegetative and flowering stages of the crop. It is also important to ensure that the fertilizers are evenly distributed in the field.
Foliar Application: In addition to soil application, foliar application of nutrients is also beneficial in the guar crop. Foliar spray of nutrients like micronutrients and growth regulators helps to improve crop growth, yield, and quality.
Conclusion: Nutrient management in guar crop is essential for achieving maximum yield and quality of the crop. The application of organic manures and mineral fertilizers should be based on soil test results and the nutrient requirement of the crop. The fertilizers should be applied at the right time and in the right amounts to ensure even distribution in the field. Foliar application of nutrients is also beneficial in the guar crop. A well-managed nutrient program can help to improve the productivity and profitability of the guar crop.
