“Row‐crop cultivation of no‐till soybean did not result in any measurable yield differences, but for grain sorghum, row‐crop cultivation resulted in an average yielddecrease of 6 bu/acre. Soil organic matter tended to be greatest for the continuous no‐till system and lowest for the plow system.”
In untreated cluster bean, 1,000 Meloidogyne javanica juveniles per kg soil significantly decreased yield, fresh shoot weight and length relative to the check.
“In cluster bean, a significant decrease in yield was associated with 10,000 second stage juveniles/kg soil in Rhizobium-treated plants, whereas 1,000 juveniles decreased the yield, fresh shoot weight and length significantly in untreated plants over the check”

“Theoretical analyses of fluorescence parameters under steady-state photosynthesis suggest that the increase in the non-photochemical quenching was due to an increase in the rate constant of thermal dissipation of excitation energy by PSII and that the decrease in the quantum yield of PSII electron transport was associated with a decrease in the rate constant of PSII photochemistry”
