Discover essential facts about fertilizers used in sesame cultivation and how nutrient management affects crop outcomes. Perfect for refreshing your knowledge of best practices in sesame agriculture.
What is the most common primary nutrient recommended for boosting sesame growth during the vegetative stage?
Explanation: Nitrogen is the main nutrient sesame requires for early growth, promoting robust vegetative development. Potassium is more crucial during flowering and seed setting. Calcium and zinc are important but not typically the leading nutrients needed at the vegetative stage.
At which growth stage is it generally recommended to apply the first split of nitrogen fertilizer to sesame?
Explanation: Applying nitrogen at sowing helps young sesame plants establish healthy growth. Fertilization during flowering or at maturity is usually too late, and application after harvest offers no benefit for the current crop.
Why is boron sometimes added to fertilizer programs in sesame cultivation?
Explanation: Boron plays a key role in flower and seed development, thus improving seed set. It does not significantly increase leaf size, prevent stem lodging, or directly lengthen plant height in sesame.
What is the primary reason farmers are advised to conduct soil testing before fertilizing sesame?
Explanation: Soil testing helps determine the nutrient content and deficiencies present, improving fertilizer recommendations. It does not help with time management, seed variety selection, or pest resistance directly.
Which organic amendment is commonly recommended to enhance soil fertility for sesame crops?
Explanation: Farmyard manure improves soil structure and nutrient availability for sesame. Rock phosphate is primarily a phosphorus source, synthetic urea is inorganic, and lime solution is used for pH adjustment rather than as an organic amendment.
