| Abstract:
The 4-year (1998-2001) investigation revealed that (a) drip-irrigation and -fertigation significantly increased tomato yield over non-treated controls; (b) percentage of tomato fruit with blossom-end rot (BER) was reduced significantly to the negligible levels in drip-irrigated and -fertigated treatments.; and (c) drip-fertigation exerted significant yield advantage over drip-irrigation only in the year when rainfall was below normal during the periods of flowering, fruit set and fruit growth as experienced in the 2001. There were significant interactions between BER and the amount of rainfall; the more the rainfall the less BER. When the rainfall was insufficient during those periods, fertigation effected better reduction of BER than irrigation. In conclusion, it can be said that drip irrigation can be profitable in any year in this region. Irrigation not only increased yield but also controlled BER to nearly negligible levels. | |
