EFFECT OF IRRIGATION REGIME ON CANE AND SUGAR YIELDS OF VARIETY NCo376IN THE SOUTH-EAST LOWVELD OF ZIMBABWE
ثبت نشده
چکیده
Various irrigation regimes were applied to NC0376 over five years of low rainfall (average 466 mm per annum). Cane yield increased, depending on amount of water applied, from 84 to 122 t/ha. There was no significant effect on quality. The lowest application of 660 mm of irrigation produced 69% of the yield produced by the standard (full) irrigation (1 520 mm) at 12 months of age. There were no plant deaths. Furthermore, irrigating according to an Et/Eo ratio of between 0,70 and 0,85 has shown potential for saving irrigation water without a large reduction in yield.

Performance of Varieties N14 and Nco376 in the South-east Lowveld of Zimbabwe
Varieties NCo376 and N14 are the most widely grown varieties in Zimbabwe and are used as control varieties in the selection programme. The success of NCo376 was due to its high yield potential throughout the year and its ability to maintain good yields, even in advanced ratoons. A study was done to compare the performances of N14 and NCo376 in the South-East Lowveld of Zimbabwe, using data from...

Sugarcane breeding is expensive because the plant is perennial and the frequency in obtaining superior clones is low. Plant breeding involves developing strategies that will increase the probability of identifying superior varieties. This paper discusses the strategies used to select varieties with high sugar yield, good disease and pest tolerance and adaptable to the South-East Lowveld of Zimb...
