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

There are several ways to eliminate virus, suach as the application of thermoterapi and chemotherapy technique, and also the apex and meristem culture. One way to control this disease is the use of virus-free seedlings. The objective of this study was to find out the effect of combined treatment between thermotherapy or chemotherapy with apex or meristem culture to mosaic virus elimination of sugarcane. There were four steps in this research: (1) Virus detection of mother plant, (2) Application of thermotherapy at 50oC and chemotherapy by using Ribavirin 25 µg/l combined with apex culture, (3) Application of thermotherapy and chemotherapy combined with meristem culture, and (4) Evaluation of virus elimination. The plant materials used were PS862 from Cirebon (PS862-Crb), PS881 from Surabaya (PS881-Sby) and PSJK922 (PSJK922-Bgr) from Bogor. Virus detection was conducted by TEM and RT-PCR analysis. The temperature for thermotherapy was 500C and the antiviral agent was Ribavirin (0 and 25 μg/l). The result showed that thermotherapy or chemotherapy combined with apex culture could not eliminate virus infection. The combined treatment of chemotherapy and meristem culture could eliminate SCSMV in variety PS862-Crb based on RT-PCR assay, however TEM analysis still detected the viral particle. It was suggessted to udertake virus indexing of large number of samples to see the rate of virus elimination.Keywords: Saccharum officinarum L., Ribavirin, Potyvirus, TEM, RT- PCR

Abstract

The effect of living post and pepper vines primings on the pepper yieldTo obtain good yield of pepper, farmers fequently apply various treatments to their crops, including pruning of the pepper vines and or their living post. Studies on the aspects of the pruning ae however very limited. Therefore a ield experiment was conducted to investigate the effects of pruning of pepper vines and their living post on the pepper yield. The experiment was carried out at Sukamulya Research Station, Sukabumi. A split plot design with three rcplicaties was used. The main plot was the pruning of living post, and the sub plot was the pruning of pepper vines Plot size was 20 plants per plol wilh spacing of 2.5 m x 2.5 m Results showed that there was signiicant interaction between the pruning of living post and pepper vines. The pruning of living post may be carried out either 3 times (October, January and April) or twice (October and January) a year. However. If the pruning of the living post is carried out 3 times per year, Ihe vine would be pruned once a year or not at all. On the other hand, if the pruning of living post is carried out twice a year, the pepper vines would be pruned 6 times a year.

Return to scale and relative economic eficiency of coconut cropping pattern at farmer level in Tasikmalaya District, West JavaInformation about the return to scale condition in coconut cropping pattern production process is very important to determine the farm measure¬ ment due to economic eficiency of farming system. This also occurs in different relative economic efficiency in the inter category in participated fanner based on their mixed cropping area. For that reason, it is urgent to carry oat the study in Cipatujah, Sindangkerta, and Cikawung Ading villages, Cipatujah Sub Distict, and Kelapa Oenep, Kujang, and Saimukti villages, Karang Nunggal Sim District, Tasikmalays District, West Java This study was conducted from June-October 1997 using survey method.
