Abstract

The use of post tin mining land for agricultural purpose is constrained by the coarse soil texture (sand), low C-organic, acid pH and low nutrient content which can be rehabilitated with soil ameliorant treatment. The research objective was to determine the best soil management of post tin mining land through the use of soil ameliorant, fertilizer, and mycorrhiza application for rubber plant growth. The research was conducted in Mandor District, Landak Regency, West Kalimantan, from 2014 until 2015. The experiment design was a split plots with 3 replications. The main plot was the use of ameliorant i.e M1 (16 kg of compost + 24 kg of quartz tailings), M2 (16 kg of clay soil + 24 kg of quartz tailings),  M3 (8 kg of compost + 8 kg of clay soil + 24 kg of quartz tailings), and control (without soil ameliorant). Subplot was fertilizer dosage i.e D1 (100% of the recommended doses), D2 (100% of the recommended doses + 100 g of mycorrhiza), D3 (125% of the recommended doses), D4 (125% of the recommended doses + 100 g of mycorrhiza). The study was conducted at altitude of  50 m asl, type A climate, annual rainfall at 2.600 mm, sandy soil (82.2%) with very low N (0.09%), very low K (0.08 cmol (+)/kg), and low P (9.24 ppm). Variables observed were the rubber plant growth (plant height, stem diameter, and number of leaves). Result showed that optimizing the rubber growth at post tin mining land needs soil ameliorants application such as compost and clay. Meanwhile, the optimal dose of fertilizer is 125% of the recommended dose plus 100 g of mycorrhiza.

Abstract

Kemajuan program pengembangan tanaman dipengaruhi oleh ketersediaan bahan tanam unggul bermutu dengan jumlah yang cukup. Grafting merupakan salah satu cara perbanyakan benih yang dapat menjamin mutu genetik bahan tanam dan keturunan yang diperoleh umumnya  sama dengan induknya. Penelitian yang bertujuan mengetahui penampilan sifat agronomi tanaman kemiri sunan [Reutealis trisperma (Blanco) Airy Shaw] yang diperbanyak secara grafting dan seedling dilakukan di Kebun Percobaan Pakuwon, pada ketinggian tempat 450 m di atas permukaan laut dengan jenis tanah Latosol dan tipe iklim B, mulai bulan Oktober 2010 sampai Oktober 2012. Metode yang digunakan adalah observasi dengan cara membandingkan dua perlakuan teknik perbanyakan benih, yaitu secara grafting dan melalui biji (seedling), masing-masing 20 tanaman untuk setiap perlakuan. Hasil observasi menunjukkan bahwa tinggi tanaman asal grafting ternyata lebih rendah tetapi dengan lingkaran batang yang lebih besar dibandingkan tanaman asal biji. Ukuran daunnya lebih kecil tetapi dengan jumlah yang lebih banyak serta indeks luas daun yang lebih tinggi.AGRONOMIC PERFORMANCE  OF [Reutealis trisperma (Blanco) Airy Shaw] RAISED BY GRAFTING AND FROM SEEDABSTRACT The progress of plant development programs are partly influenced by the availability of planting materials, both in term of quality and quantity. Grafting is a propagation technique to ensure that the genetic quality of the provided planting materials is identic to the mother plant. A study was established to investigate agronomic performances of [Reutealis trisperma (Blaco) Airy Shaw] grown through grafting and seedling from October 2010 until October 2012. The study was carried out at Pakuwon Research Station with altitude of about 450 m above sea level, soil type of latosol and B type climate. The observations were made on 40 the plants of 20 each. Results showed that the agronomic performance of the plants grown through grafting technique was lower in height than those of seedling, but higher in stem of girth sizes than those of seed ones. Moreover, the leave sizes of grafted plants were smaller than those of the seedling, but higher in leave numbers and leaf area index compared to those of seedling.

Abstract

Leaf fall disease in rubber caused by Corynespora cassiicola fungi significantly decreases rubber productivity. C. cassiicola causes leaves to fall all year round,  a delay in the tapping of immature rubber  plants, yield decrease of producing plants, and even death of susceptible clones.  The study aimed to obtain phylloplane and endophytic microbes potentially to inhibit the disease, was conducted from January to December 2016. The study used randomized complete design to assess antagonistic fungi and phylloplane and endophytic bacterias toward C. cassiicola in isolates obtained through exploration in West Java and West Kalimantan. Pathogen isolation showed Corynespora sp with pale brown color, single conidia which slightly bended, shaped like a stick that is swollen at the base, with 2–14 septa.  Inhibitory analysis found 42 fungi isolates and 19 bacteria isolates potentially inhibiting C. cassiicola. Six fungi isolates have an inhibitory ability of ≥90%, consisting of two phylloplane fungi isolates (DTJF11 and CPSR7) and four endophytic fungi (CEBPM15, CEBPM23, CEBPM27, and CEPR9) with lysis, mycoparasitism, competition, and antibiosis inhibitory mechanism. The identification showed fungi isolate of DTJF11 is classified as  Trichoderma asperellum, CPSR7 as Talaromyces pinophilus, and CEBPM15 as Amanita tenuifolia.  Potential bacterial isolates as biological agents are BP7, L3, BP3, BP4, BP5 and BP6 isolates, which have inhibitory power of 28.54%–40.94%, with antibiosis inhibition mechanism.

Abstract

The gradual rejuvenation in rubber plantation (Hevea brasiliensis) is one alternative of rejuvenation model that able to be carried out by farmers. Hypotetically, the difference in logging percentage can effect on the growth of young rubber plant and intercrops. The objectives of this research was to investigate the effect of intercrops (corn and peanuts) on the growth of young rubber plant in gradual logging system. The research has been carried out in smallholders rubber plantation in Way Kanan, North Lampung, from January to December 2012. The study was designed by split plot design with 3 replications. The main plot are the logging percentage, (P1) 30%, (P2) 50%, (P3) 70%, and (P4) 100%, and the subplot are the kind of intercrops: corn and peanuts. The results showed that corn as intercrop in logging percentage of 30%, 50%, and 70% did not effect on the stem diameter of young rubber, but if peanut as intercrops can inhibit the growth of stem diameter of young rubber. The logging percentage of 70% did not effect on the growth and yield of corn and peanut as intercrops.

Abstract

Gradual rejuvenation model is an option to increase the productivity of smallholder rubber plantation due to old and damaged plants. The limitation of this model is the high variation of the growth of young plant in the field. This study aimed to determine the effect of extra fertilization and mycorrhiza on the growth of young rubber plants in the gradual rejuvenation model. The research was located at Ramsay Village, Way Tuba District, with red-yellow podzolic soil types and climate type of B2 according to Oldemand, from 2012 to 2014, and arranged in split plot design. The plant age, P1 (3 years old); P2 (2 years old); and P3 (1 year old) was denoted as the main plot, whereas the subplot is fertilizer dosage, D1 (100% of recommended dosage); D2 (100% of recommended dosage + mycorrhiza; D3 (125% of recommended dosage); D4 (125% of recommended dosage + mycorrhiza). Fertilizer application was done twice a year, while mycorrhiza were given once a year toward the end of the rainy season. The plant material used was PB 260 clone, with a standard agricultural practices such as weeding and watering during the dry season. Variables measured were plant height and girth. The results showed that application of 25% extra from the recommended dosage + mycorrhiza was able to accelerate the growth of young rubber plants. Fertilizer dose of 125% from the recommendation + mycorrhiza applied on 2-year-old plants exhibited the same growth with 3-year-old plant that treated with recommended dosage. This result indicates that mycorrhiza works synergistically with inorganic fertilizer, which enhances the effectivity and efficiency of extra fertilization in gradually rejuvenation models.

Demikian juga bentuk kanopi tanaman pala yang berasal dari grafting dengan pucuk asal cabang ortotrop, kanopi lebih sempurna tumbuh ke atas, sedangkan yang berasal dari pucuk plagiotrop tumbuhnya menyamping.MORPHOLOGY CHARACTER OF NUTMEG RAISED BY GRAFTING TECHNIC USING PLAGIOTROP AND ORTOTROP BRANCHABSTRACT Nutmeg plant may be multiplicated through grafting technique by splicing of young shoots (entrees) as upper parts onto seedlings as a bottom parts. The both parts are usually taken from selected perennial lines or the mother plants. The young shoots are usually taken from orthotropic or plagiothrop branches.  A study was conducted at Sukamulya Research Station (Sukabumi) with elevation of 350 m above sea level,  the climate type of B (Schmidt and Fergusson), and soil type of red latosol  from 2010 to 2012. The aim of this study was to find out good entrees in providing of grafted seedlings in nutmeg plant. The treatments evaluated were the use of entrees taken from ortothrop and plagiothrop branches. A number of sampled plants observed were 10 plants of each treatment, whereas parameters observed were plant height, stem diameter, number of branches, length leaf, leaf area index, number of leaves and shape of canopy. The results shows that grafted nutmeg plants developed from ortothrop branches had higher in plant height, stem diameter, number of branches, length of leaf, leaf area index, number of leaf and shape of the canopy showing a good their performance  and significantly different compared to those of plagiothrop branches. In addition, the former was growth up vertically, while the later was growth up horizontally.

Abstract

Recommendation of Robusta coffee fertilizer that available until now is only in general. In fact, the type and amount of fertilizer needed is highly dependent on environmental conditions, clones, and plant age. The study aimed to investigate the effect of combination doses of urea, SP36, and KCl fertilizer on growth, yield, and bean quality of four Robusta coffee clones cultivated in red-yellow podzolic soil type (PMK), North Lampung. The study was conducted at KP. Cahaya Negeri, North Lampung, with the altitude of 250 m above sea level, PMK soil type and climate type of C (Oldemand), from October 2011 to June 2014. The research was arranged in split plot design with four replications. The main plot was four Robusta coffee clones i.e. (K1) = BP 42; (K2) = BP 409; (K3) = BP 936; and (K4) = BP 939, while the subplot was four combination doses of urea, SP36, and KCl i.e. (P1) = 30:20:20 g/tree; (P2) = 40:30:30 g/tree; (P3) = 50:40:40 g/tree; and (P4) = 60:50:50 g/tree. The results showed that four Robusta coffee clones (BP 42, BP 409, BP 936, and BP 939) cultivated in PMK soil type, KP. Cahaya Negeri, North Lampung, had the same response to combination doses of urea, SP36 and KCl fertilizer. The combination doses of urea, SP36, and KCl of 50, 40, and 40 g/tree, respectively were optimal and efficient for growth and yield of those four clones until 2.5 years old. However, the dose has not yet been able to improve the quality of coffee beans.

Abstract

Volume and type of growing media is important to support the growth of rubber seedling (Hevea brasiliensis) for rootstocks. The objective of this study was to determine the growth of rootstock and green budding success of rubber plants in different size of polybag and growing media. The research was carried out since January to December 2013 at the Pakuwon experimental garden, Parungkuda District, Sukabumi Regency, West Java. The study used a randomized block design (RBD) in factorial with two factors and three replications. The first factor is the sizes of polybag: (1) 30 ´ 20 cm, (2) 35 ´ 20 cm, and (3) 40 ´ 20 cm. Meanwhile, the second factor is the growing medium that consists of the mixture of soil and cow manure with 4 proportions: (1) 1 : 0, (2) 3 : 1, (3) 2 : 1, and (4) 1 : 1. Observations were made on the growth of pre-budding rootstock including seedling height, seedling diameter, number of leaves, and the success percentage of green budding. The results showed that the size of polybag has positive effect on the growth of the rubber seedling as rootstock at 6 months old after planting. Moreover, the use of large sizes of polybag (30 x 20–40 x 20 cm) was good for the growth of rootstocks that would be used for green budding. In addition, growing media that consisted of soil and cow manure at a comparison of 1 : 1 gave the highest effect on the growth of rootstock as well as the highest percentage of green budding success. However, there is no interaction between the size of polybag and growing media to the growth of rootstock and green budding success.
