Stomatal Conductance and Chlorophyll Characteristics and Their Relationship with Yield of Some Cocoa Clones Under Tectona Grandis, Leucaena SP., and Cassia Surattensis.

An optimum physiological condition will support high yield and quality of cocoa production. The research was aimed to study the effects of stomatal conductance and chlorophyll content related to cocoa production under three shade regimes.This research was conducted in Kaliwining Experimental Station, elevation of 45 m above sea level with D climate type based on Schmidt & Fergusson. Cocoa trees which were planted in 1994 at a spacing of 3 X 3 m were used in the study planted by using split plot design. The shade tree species were teak (Tectona grandis), krete (Cassiasurattensis), and lamtoro (Leucaena sp.) as the main plots, and cocoa clones of Sulawesi 01,Sulawesi 02, KKM 22 and KW 165 as sub plots. This study showed that there was interaction between cocoa clone and shade species for stomatal conductance where stomatal diffusive resistance of KKM 22 was the best under Leucaena sp.and Cassiasurattensis with the values of 1.38 and 1.34 s.cm -1, respectively. The highest chlorophyll content, stomatal index and transpiration values was under Leucaena sp. shade. There was positive correlation between chlorophyll content and transpiration with pod yield of cocoa. The highest yield and the lowest bean count wereobtainedon Sulawesi 01 clone under Leucaenasp. shade

A Study of Allelopathy of Some Shade Trees to Coffea ArabicaL. Seedlings

Because of social economic judgment, many coffee planters nowadays grow Cassia spectabilisand in the certain regions used Cinnamomum burmani, Macadamia integrifolia, Tectona grandisand Cassia siameaas shade trees or intercrops. Before being used in large scale, allelopathy study is appropriate to be done because this effect is much more difficult to be overcome than competiton as growing factor. Research on allelopathy of those species had been conducted in glasshouse of Indonesian Coffee and Cocoa Research Institute using Salisbury & Ross method. Leachate of Cassia spectabilis Cinnamomum burmani, Macadamia integrifolia, Tectona grandisand Cassia siamea, pure media (without plant) and control (well water) were used as treatments. Planting material of Cinnamomum burmani, Macadamia integrifolia, Tectona grandisand Cassia siameawere as seedlings of one year old, whereas C. spectabiliswas 3 months old. Those materials were planted in polybags 20 cm x 30 cm and replicated five times. The media was a mixture of top soil, manure and sand 1 : 1 : 1 (v/v). After those species were maintained for one months and Arabica seedlings for three month old, watering of coffee seedlings then using leachate from shade trees media. Every two days, each seedling was applied with 200 ml. Control was applied with well water. Pure media was used to study the effect of nutrient supply contained in the leachate. The experiment was stopped at seven month old of the coffee seedlings. The result showed that C. spectabilisreleased chemicals which showed allelopathic effect to Arabica coffee, their growth was inhibited 10% to control. The growth decreament from Cassia siameaand D. zibethinustreatment mainly caused by lower mineral content in the leachate and indicated by weak allelopathic. On the other hand M. integrifoliaand C. burmanidid not show allelopathic to Arabica coffee. Thus, based on allelopathy aspect, it can be included that C. spectabilisand C. siamea were not recommended as shade trees or intercrops with Arabica coffee and for D. zibethinusits cropping pattern must be arranged so the mineral competition could be maintained minimum

Pattern of Flushing, Cherelle Wilt, and Accuracy of Yield Forecasting of Some Cocoa Clones

Monthly observation of cocoa flushing, number of cherelle wilt (CW), number of small, medium and large pods of 6 clones was conducted for two years to study its dynamics for one year. A study was conducted in Kaliwining Experimental Station, 45 m asl. and D rainfall type (according to Schmidt & Ferguson), using ICS 13, ICS 60, TSH 858, Sulawesi 1, Sulawesi 2 and KW 165 clones of 8 years old. Each clone was planted intermittently in separate rows, replicated 6 rows. Correlation and regression analysis were done between variables and with rainfall data. The parallel research was conducted in the similar station to assess the accuracy of production estimation method by identify percentage of small pods (length 1—10 cm), medium (11—15 cm) and large pods (>15 cm) to grow until harvested. The study used 15th years old trees of Sulawesi 1, Sulawesi 2, KW 165, KKM 22, ICS 13 and DR 2 clones. Each clones was replicated 5 times. The result showed that intensive flushing (>50%) occured during January, March, September and November meanwhile no flushing during December and February. Correlation between rainfall and flushing was positive (r=0.27). Effect of clones on flushing frequency was similar but for flushing intensity was significant. KW 165 tended to be the lowest but TSH 858 tend to be the highest. CW occured for a year-round but the height level during May and June. Effect of clones was significant, KW 165 showed highest followed by Sulawesi 2. CW level showed positive correlation with number of medium (r=0.71) and big pods (r=0.55), except showed negative correlation with flushing intensity (r=-0.37) and rainfall (r=-0.51). High pod setting happened during May to November and low pod setting during December to March. In this aspect effect of clones were significant, the productive clones were Sulawesi 1, Sulawesi 2 and KW 165, but ICS 60 was the less. CW level during 1st semester was lower than at 2nd semester and clone effect was significant. The opportunity of small, medium and big pods to be harvested was similar among both semester. The opportunity of small, medium and big pods to be harvested were 8—56%; 57—83% and 77—96% respectively depend on the clones. In average, those opportunities were 27%, 72%, and 87% for small, medium and big pods respectively

Soil Nutrient Condition of Coffee Cultivation with Industrial Woody-crops

Black pod rot disease (BPRD) which is caused by Phytophthora palmivora is one of the main diseases of cocoa cultivations particularly in plantations with wet climate. Black pod rot can develop rapidly under high humidity environments, particularly during rainy seasons. This disease can cause loss of harvest of up to 46.63% in East Java. The various control efforts attempted so far have not resulted in significant improvements. Urea, in addition to functioning as fertilizer, can also produce the ammonia gas which is believed to be able to suppress black pod rot. This research aims to determine the effectiveness of black pod rot control using the combination of lime and urea. This research was conducted from June to September 2013. The materials used in test included sterile soil, black pod rot infected cocoa, urea, and agricultural lime. Observation results showed that ammonia could form from urea. Lime can increase the speed of the formation. The ammonia gas forming from 0.06% urea and 0.3% lime can control the P. palmivora fungus inside the soil

Early Yield and Economical Study of Pogostemon Cablinas Intercrop in Young Cocoa (Theobroma CacaoL.)

Pogostemon cablinis an important source of volatile oil for pharmaceutical and cosmetical products. Agronomical aspect of this commodity needs open ecosystem, but for certain level of shading, this crop may yield economically. A study to evaluate the effect of P. cablinintercropped on young cocoa farm, had been conducted during 2005, in Kaliwining Experimental Station of Indonesian Coffee and Cocoa Research Institute (ICCRI) 45 m above sea level, D climate type (Schmidt and Fergusson), and on low gley humic soil. The experiment was arranged in factorial and the field design was split plot replicated three times. The main plot was no shade tree, shade of Leucaena glauca and Areca catechuwhile the subsplots were fertilizer dose (per ha/year), i.e. (P0) without fertilizer; (P1) 140 kg Urea, 35 kg SP-36, 70 kg KCl; (P2) 280 kg Urea, 70 kg SP-36,140 kg KCl; and (P3) 560 kg Urea, 140 kg SP-36, 280 kg KCl. The result showed that P. cablin cultivation without shading gave better growth and yield than the shading treatment; meanwhile Leucaenashading showed better growth and early yield than the A. catechushading. Fertilizer rate of P1 produced highest leaf weight and oil yield, although P3 possessed the highest growth variables of plant height, stem diameter, number of leaves, leaf area and chlorophyll content. For the dry weight biomass variable, highest yield was obtained from no shade tree and P1 treatment. Using chromatography gas analysis, retention time of patchouly alcohol is 15—18 minutes, it was found that the content was influenced by shading treatment, i.e. 25.15% in monoculture, 28.73% in Leucaena and 25.21% in A. catechutreatment. For the oil viscosity variable, the monoculture treatment showed the highest value (23.21 centipoise), followed by A. catechu(11.60 centipoise) and Leucaenatreatment (8.65 centipoise). Intercropping of P. cablinwith young cacao did not show negative effect on young cacao growth. This study demonstrated that pre-cropping ofP. cablinin young cacao provided opportunity to farmers to have additional income, the benefit cost ratio (B/C) for Leucaenatreatment 1.00–1.35 depend on dose of fertilizer, while for A. catechutreatment gave no profit (B/C 0.59–1.03 depend on fertilizer dose). Meanwhile, P. cablinmonoculture cultivation gave B/C 1.44–2.71

Carbon Stock in Different Ages and Plantation Systemof Cocoa: Allometric Approach

Indonesia has 1.5 million hectare of cocoa plantation in 2008. which hasstrategic position in carbon dioxide absorption to decrease global warming. Biomass approach method in plants carbon stock estimation specific for cocoa is still not available. The aim of this research is to determine carbon stock in 1—30 years ages of cocoa plants and to measure carbon stock in various cocoa planting systems using specific allometric formula of carbon stock estimation. Regression model on plant biomass estimation was estimated based on height, diameter, and their combination. Carbon stock estimation in different ages and plan tation system of cocoa was conducted by randomized completely block design with 3 replications. The result showed that model Y:áDâ as the best allometric formula, where Y is plant biomass, D is diameter at the breast hight, â is a constant with a value of 0.1208 and á was a constant of 1.98. Increasing of carbon stock in cocoa plantations was proportional to the ages of the plants according to the polinomial equation Y=0.0518X2+2.8976X–4.524. Agroforestry system increased carbon stock in cocoa plantation. Cocoa-Paraserianthes falcataria plantation system produce highest of carbon stock in 7 years

Variability of nutrient absorption in several cocoa planting materials

A study on nutrient absorption of Trinitario and Forastero cocoa types had been conducted in Kaliwining Experimental Garden and the laboratory of plant analysis of the Jember Research Institute for Estate Crops (JRIEC) since June 1987 until March 1988. Trinitario type was represented by four groups of cultivars i.e.Djati Roenggo (three DR series) Djati Roenggo Clone (13 DRC series), Kaliwining Clone (six KWC series), and Imperial College Selection (three ICS series). Forastero type was represented by two groups of cultivar, i.e. Getas Clone ( seven GC series),and Scavina (three Sea series). The seedlings of propelegitimate seeds were used. The results showed that under the same environmental condition there were significant differences between the two cocoa types in the absorption of K, Mg, Cu, and Mn. Trinitario type showed high absorption for K and Mn, but lower in the absorption of Mg and Cu compared to Forastero type. Among cultivar's group within Trinitario type there were differences in the absorption of N, P, K, Mg, Cu, and Mn. ICS group showed high absorptionfor N, KWC for P and K, DRC for Cu, ICS for Mn, and DR, DRC and ICS for Mg. In the Forastero type, GC group showed high absorption for P, but Sea group had the highest absorption capacity for K, Mg, and Mn. No significant difference was observed between the series within each cultivar group
