Explore the nutrition and key growth factors for green gram in agriculture. Learn essential facts that contribute to optimal yield and plant health.
Which macronutrient is most critical for healthy leaf development in green gram crops?
Explanation: Nitrogen is essential for leaf development because it promotes chlorophyll formation and vegetative growth. Phosphorus mainly supports root and seed development, potassium aids in water regulation, and calcium, while important, is not the primary driver for lush leaves in green gram.
For optimal nutrient absorption, what is the ideal soil pH range for cultivating green gram?
Explanation: Green gram thrives best in slightly acidic to neutral soils, with a pH between 6.0 and 7.5 for effective nutrient uptake. Lower or higher pH levels can restrict nutrient availability, making the other ranges less suitable for healthy crop growth.
Yellowing of green gram leaves, especially between the veins, is most commonly caused by a deficiency of which micronutrient?
Explanation: Iron deficiency typically leads to interveinal chlorosis (yellowing between veins) in green gram leaves. Copper and boron deficiencies cause different types of symptoms, and molybdenum deficiency affects nitrogen fixation rather than leaf color.
Why is rhizobium bacteria important for green gram nutrition on farms practicing sustainable agriculture?
Explanation: Rhizobium bacteria form nodules on green gram roots to convert atmospheric nitrogen into forms usable by the plant. The other options do not describe the main function of rhizobium in the context of green gram nutrition.
At which growth stage does green gram have the highest demand for potassium?
Explanation: During the pod filling stage, green gram requires more potassium to support seed development and improve yield quality. Seedling emergence and flowering need less potassium, while land preparation occurs before nutrient demand peaks.
