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.

Effects of water stress on plant growth and production of cashewTo complete the characteristic tests of prospective numbers of cashew (Anacardium occidentale L). research on the production stability and envi¬ ronmental stress tolerance were conducted. The objectives of the research were to study the effects of the water stress on the growth performance, inflorescent formation, production and quality of cashew. The research activi¬ ties wee caried out at Cimanggu Research Insulation from Apil 1995 to March 1998. The research used factorial randomized block design with 3 replications and 4 plants per pot. The treatments tested were wateing intervals (A) of 2, 4. 8. and 12 days with 9 mm deep of water for each treatments Prospective numbers of cashew (N) namely Pecangakan. Jepara F2-10. Balak¬ risnan B-02. and Silanka S-21. The results obtained 13 months ater gratings or 11 months ater the application showed that water stress and prospective numbers significantly affected the vegetative growth of the plants namely plant height, primary branch number, secondary branch numbers and canopy diameter. Amongst the prospective numbers, Balakrisnan B-02 had lower growth rate compared with Pecangakan. Jepara F2-I0, and Silanka S-21. Water stress significantly affected the formation of inflorescence, which tended to decrease along with the increase of water stress. On the same level of water stress, the inflorenscent formation of Jepara F2-10 was more domi¬ nant than the other numbers. However the proportion of male flowers, hermaprodite, and the ratio ofhermaprodite flowers to total number of flowers wee not significantly affected by water stress. The difference of inflorescent formation of prospective numbers was significant on the formation of the male flowers only, the highest was Srilanka S-21 and the lowest was Jepara F2- 10. The water stress showed significant effect on the number of the pods per tree, production and the protein content of the cashew nuts. The number of pods per tree and the production tended to decrease along with the increase of water stress, while the protein content of the cashew nut tend to increase along with the water stress incease The number of pods and production per tree were highest on Balakisnan B-02 followed by Pecangakan. Jepara F2-10 and Silanka S-21. espectively, where as the highest protein content of Ihe cashew kernel was on Balakrisnan B-02.

Response of three bushy black pepper vaieties to organic fetilizerResponse of three bushy black pepper varieties to organic fertilizer was studied in Sukamulya Research Insulation, rom February 1992 to August 1995. The plant materials used wee pepper cuttings deived rom generative branches. The field tial with factorial treatments was designed in a random¬ ized block with three replicates and 9 plants per plot The varieties tested were : a) Lampung Daun Lebar (LDL), b) Merapin, and c) Kuching. The organic fertilizer used wee : (a) Control, (b) 800 g OST (organic soil treatment) per plant per year and (c) 20 kg cattle manure per plant per year. The esults indicated that Kuching it the best in terms of the number and length of pimary branches, canopy area, number ofberries per spike, and spike length. Fertilizer ■tauuuuts as well as its interaction with varieties had no significant efect on yield at the first harvest. Catle manure had significant effect on to spiked and dried berries it die second harvest However, based on toul production of dried teed*, var. LDL and Kuching gave a significantly higher yield compared with Merapin.
