Question

Given below are two statements:
Statement (I): In Soyabean, generally, 75-80 kg/ha seed is recommended in kharif
Statement (II): For spring season soyabean crop, 100 kg/ha seed is recommended
In light of the above statements choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Spring soybean requires higher seed rates due to reduced branching and shorter vegetative period compared to kharif crop.

Answer 1

The Correct Option is A

Kharif season:
75
80 kg/ha seed rate is standard recommendation
Due to monsoon conditions and better soil moisture
Spring season:
100 kg/ha recommended for higher plant density
Compensates for shorter growing period and water stress

Answer 2

Agronomic-principle reasoning:
Seed rate recommendations are driven by the target plant population needed to compensate for expected losses and the length of the growing window. In the kharif (monsoon) season, soybean benefits from good soil moisture and a longer vegetative period, so a comparatively lower seed rate of 75-80 kg/ha is sufficient to achieve optimum plant stand. In the spring season, crop duration is compressed and moisture availability is less assured, so agronomists recommend a higher seed rate, around 100 kg/ha, to ensure adequate plant density and compensate for the shorter, more stressed growth period. Both figures are consistent with standard soybean agronomy recommendations for their respective seasons.
Hence, both Statement I and Statement II are true.
