Sure, here’s an article on growth regulators used to improve pod filling in gram:
Gram, also known as chickpea, is an important legume crop grown in many parts of the world. It is a rich source of protein, fiber, and carbohydrates, making it a valuable food crop for both humans and livestock. However, gram plants often suffer from poor pod filling due to various factors, such as unfavorable weather, pest attacks, and nutrient deficiency. To overcome this problem, the application of growth regulators is often recommended.
Growth regulators are plant hormones that stimulate or inhibit various plant growth processes. They can be synthetic or naturally occurring and are used to control various aspects of plant growth and development. In gram, growth regulators are used to improve pod filling by increasing pod size, reducing flower drop, and enhancing seed quality.
One of the most commonly used growth regulators in gram cultivation is gibberellic acid (GA). GA is a naturally occurring hormone that promotes cell elongation and division, leading to increased pod size. It also stimulates the synthesis of enzymes responsible for the synthesis of sugars, amino acids, and other nutrients required for seed development. GA is typically applied to gram plants during the pre-flowering stage to improve pod filling.
Another growth regulator commonly used in gram cultivation is 2,4-D (2,4-dichlorophenoxyacetic acid). 2,4-D is a synthetic hormone that promotes the formation of flowers and fruits by preventing the natural shedding of buds and flowers. By reducing flower drop, 2,4-D can improve pod filling in gram plants. It is usually applied during the vegetative stage of plant growth.
In addition to GA and 2,4-D, other growth regulators such as cytokinins and auxins have also been used to improve pod filling in gram. Cytokinins stimulate cell division and delay leaf senescence, leading to increased pod size and longevity. They are typically applied during the pre and post-flowering stages of plant growth. Auxins, on the other hand, promote the formation of flowers and fruits by enhancing cell expansion and differentiation. They are usually applied during the vegetative stage of plant growth.
Overall, growth regulators are an effective way to improve pod filling in gram plants. By stimulating cell division, preventing flower drop, and enhancing nutrient synthesis, growth regulators can significantly increase the yield and quality of gram crops. However, it is important to use these growth regulators at the recommended doses to prevent any negative effects on plant growth and development.
