Other claims from this paper (8)

Intervention effect Sowing okra 4 and 5 cm deep significantly decreased vegetative growth, dry matter accumulation and yield.
Intervention effect The 5 cm sowing depth appears to be the most damaging for okra.
Recommendation 3 cm is the optimum sowing depth for okra.
Intervention effect The 3 cm sowing depth gave the highest yield and overall best performance of okra.
Intervention effect Sowing at 1, 2 and 3 cm gave good seedling emergence.
Association NHAe 47-4 out yielded LD88 in okra.
Mechanism The yield advantage of NHAe 47-4 over LD88 is apparently due to its larger leaf area and fruit size.
Observation The two okra varieties responded similarly to sowing depths.
