Abstract
In 1974 sorghum cv. Co H.2 was irrigated at 50% available moisture continually or at combinations of seedling, vegetative, flowering and grain formation stages. Grain and straw yield were 4.7 and 7.55 t/ha, resp. where irrigation was applied at all 4 stages compared with 4.5 and 8.0 t/ha with continuous irrigation. Omitting irrigation at the seedling or vegetative stage reduced grain yield by 32 and 41%, resp., whereas omitting irrigation at the flowering stage reduced yield by only 10%. In 1975 sorghum cv. CSH 5 and CSV 4 yielded less when irrigated at the seedling stage due to heavy rainfall and waterlogging. CSH 5 gave higher grain and straw yields than CSV 4 under most treatments. In both cv., application of 90 kg N/ha gave higher yields under moisture stress than applications of 45 or 135 kg N/ha. Response to 135 kg N/ha occurred only under continuous irrigation
