Abstract

Prediction of dryspell and the onset of rainy season to im¬ prove cotton planting time in East JavaClimatic elements paticularly rainfall strongly influences successful prediction of rainfed cotton yield. Rainfall variability varies amongst the seasons. Thepreviousplantingtimcs were determined based in 10 years daily rainfall data (1975-1984). Longterm rainfall data are required for rainfall analysis to get reliable probabilities The rainfall analysis was done using Markov Cham First Order Probability and dryspcll probability methods. The rainfall data were collected from 17 rainfall stations in East Java (Banyuwangi, Situbondo. Probolinggo, Jember, Lumajang, Pasuruan, Mojokerto.Tuban and I -amongan). The planting times varied from the first week to the fouth week of December for Pasuruan, Probolinggo. Situbondo, Jember. and Banyu¬ wangi: for these areas sequential system of cotton ater maize is not recom¬ mended due to short rainy season The planting times in Lumajang. Lanongan. Mojoketo. and Tuban ranged from mid December to early January, sufficient length of rainy season suppoted sequential system in these areas. The improved cotton planting times were 1 -2 weeks earlier or later than the previous planting times.

Abstract

Cotton Planting Times in South SulawesiClimatic elements particularly the rainfall strongly influences successful production of rainfed cotton (Gossypium hirsutum). Planting times determined based on more than 20 years daily rainfall data. The rainfall was analyzed using Markov Chain First Order Probability and dryspell probability methods The rainfall data were collected from 46 rainfall stations over Jeneponto, Soppeng, Wajo, Gowa, Bone. Bulukumba. Bantaeng, and Takalar. The planting times varied from the irst week to the fourth week of December for Jeneponto, Takalar, and mostly Gowa. The planting times in Soppeng and Wajo were ranged from the third week of February to the third week of March. Morever, cotton planting times in Bone and Bulukumba were ranged from the third week of March to the third week of April.
