Other claims from this paper (12)
- Intervention effect N fertilizer did not influence corn yields in the nonirrigated treatment.
- Intervention effect Plant density did not influence corn yields in the nonirrigated treatment.
- Intervention effect In the irrigated treatment, corn yields increased in both plant densities when N fertilizer was applied.
- Observation Grain yields were most influenced by the number of kernels produced per unit area.
- Intervention effect N fertilizer did not appreciably affect the corn evapotranspiration rate.
- Intervention effect Plant density did not appreciably affect the corn evapotranspiration rate.
- Intervention effect Evapotranspiration was considerably greater for irrigation plots than for nonirrigation plots.
- Observation Rates of evapotranspiration were higher in 1957 than in 1956.
- Intervention effect Water-use efficiency (dry matter per inch of water used in evapotranspiration) was appreciably increased by using a high plant density.
- Intervention effect Water-use efficiency (dry matter per inch of water used in evapotranspiration) was appreciably increased by N fertilizer.
- Observation The increase in water-use efficiency was much less marked in the nonirrigated treatments than in the irrigated treatments.
- Recommendation Adequate fertilizer and plant densities are required if maximum efficiency of moisture use is to be realized.
