Penyelidikan yang dilaporkan dalam eksperimen ini memberi tumpuan terhadap ciri fizikal dan kimia habuk sabut kelapa (CD) dan tandan kosong kelapa sawit (EFB) berpotensi digunakan sebagai media pertumbuhan bagi kobis bunga hibrid di bawah rumah tanaman di tropika yang mempunyai kelembapan udara yang tinggi. EFB dan CD mempunyai ciri fizikal optimum untuk keperluan pertumbuhan tanaman pada awal penanaman. Walau bagaimanapun, kedapatan air tersedia bagi CD adalah 34 % dibandingkan dengan 19% untuk EFB. Ruang rongga tersedia EFB , iaitu rongga yang melebihi 300 11m adalah tinggi dibandingkan dengan CD. Ciri kimia menunjukkan EFB adalah lebih alkali (PH 6.9) dibandingkan dengan CD(PH 5.3) dan rendah kekonduksian elektrik (EC) iaitu 1.3 dSm,l dibandingkan dengan CD (1.9 dSm,l). Keputusan juga menunjukkan CD mengandungi kepekatan nutrien yang tinggi dibandingkan dengan EFB. Walaupun EC asal CD lebih tinggi, jumlah bahan kering tanaman adalah tinggi dibandingkan dengan kobis bunga yang ditanam dalam EFB. Kedapatan fungi dan cendawan pada permukaan media EFB dan penguraian awal telah menyebabkan pertumbuhan tanaman yang kurang pada media EFB. Oleh itu, CD adalah media tanaman yang lebih sesuai dibandingkan dengan EFB untuk penanaman hibrid bunga kobis.
Nitrogen Utilisation of Lowland Cauliflower Grown on Coconut Coir Dust
2003
Strong wind, high rainfall, the spread of diseases during rainy season and pests problems in open field agriculture have led to the current trend in growing vegetables under protected environment. The occurrence of soil borne disease, and limited suitable land for agriculture are some of the reasons to look for alternative media such as coconut coir dust. The basic properties of coconut coir dust as a soilless growing medium and the utilisation of nitrogen (N) fertiliser for the lowland cauliflower grown in them have not been thoroughly investigated and are therefore not well understood. This study has been conducted by the need to provide a basis for determining optimal levels/concentration and forms of nitrogen supply, and by the need to minimize environmental consequences of lowland cauliflower production. It focuses on the effects of N supply in terms of different levels of N and ionic N forms in the nutrient solution, on the growth, development and N utilisation of cauliflower ...

Rice is the most important cereal crop in the world. However, yield of rice is declining due to intensive crop cultivation, soil-sickness and pest and diseases. A glasshouse study was conducted to evaluate different combinations of coconut coir dust (CCD) and compost on growth and development of Malaysian rice variety MR219. Five treatments consisting of T1 = 100% compost, T2 = Compost and CCD in 4:1 ratio, T3 = Compost and CCD in 3:2 ratio, T4 = Compost and CCD in 2:3 ratio, and T5 = 100% CCD were used in this experiment. Treatment T2 containing 80% compost with 20% CCD showed better performance for plant growth, chlorophyll content, shoot and root dry mass as well as root to shoot ratio. Therefore, the treatment containing 4:1 compost and CCD could be a suitable alternative as soilless culture for rice cultivation.

Palm oil production results in many valuable products, but it also generates agricultural wastes such as empty fruit bunch (EFB). EFB composting usually produces nutrient-enriched bio-fertilisers and thus, able to help in reducing the chemical fertilisers applied. Most conventional vegetable farmers in Malaysia solely depend on chemical fertilisers in crop production. However, the intensive use of chemical fertilisers has led to various side effects. Thus, this study was to determine the effect on the growth of choy sum by reducing the dosage of chemical fertiliser with EFB compost as soil amendments. Randomized Complete Block Design (RCBD) methods were used in this study. The fresh weight, dry weight and plant height of the choy sum were found to be not significantly different among all the treatments (T1-T4) and positive control. This study found that T4 with 30% lesser chemical fertiliser applied showed no significant growth difference with the rest of the treatments indicating that EFB may have the ability to help in reducing chemical fertili ser usage in the growth of choy sum. Further study is recommended as this will help in better EFB waste management and lowering the cost of production for local vegetables.
Methods of Correction of Vegetable Waste Compost Used as Substrate by Soilless Culture
Acta Horticulturae, 2003
One of the main environmental impacts of plastic covered horticulture is the generation of organic plant waste. The suitability of compost from horticultural greenhouse crop waste as a growing media in vegetable crop production is examined and compared to other substrate alternatives like coconut coir waste. One experiment was conducted to compare this compost with coconut coir waste in terms of the yield and fruit quality of tomato crops (Lycopersicon esculentum Mill. cv Daniela). The results suggest that compost seems to be an acceptable growing media as a substitute for rockwool and similar to coconut coir waste in soilless vegetable cultivation. The results suggest that a correct management procedure, previous acid rinsing and saturation with the standard nutrient solution are recommendable in order to reduce compost salinity and inadequate pH and thus reduce the pH and EC in the rhizosphere environment. Once the physico-chemical properties are adjusted for soilless culture, yield trials show compost is suitable as a soilless media and as a viable and ecologically-friendly alternative, like coconut coir waste, and also maintains or increases physical and physicochemical properties.
Efficacy of vermicompost and conventional compost on growth and yield of cauliflower
Bangladesh Research Publication Journal, 2014
An experiment was conducted at experimental field of the Soil Science Division, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during the period from October 2008 to March 2009 to study the effect of vermicompost and conventional compost on the growth and yield of cauliflower. The experiment comprised of twelve treatments, viz. T1: 100% Recommended Dose of Chemical Fertilizer (RDCF; RDCF= N250P35K65S40 Zn5B1 kgha-1); T2: 80% RDCF; T3: 60% RDCF; T4: 100% RDCF+Vermicompost @ 1.5 tha-1; T5: 80% RDCF+Vermicompost @ 3 tha-1; T6: 60% RDCF+Vermicompost @ 6 tha-1; T7: Vermicompost @ 6 tha-1; T8: 100% RDCF+Conventional compost @ 1.5 tha-1; T9: 80% RDCF+Conventional compost @ 3 tha-1; T10: 60% RDCF+Conventional compost @ 6 tha-1; T11: Conventional compost @ 6 tha-1 and T12: Control (No fertilization) following Randomized Complete Block Design with three replications. Maximum plant height (49.4 cm), number of leaves plant-1 (16.3), circumference of curd (46.5 cm), curd height (20.7 cm), total weight (1.60 kg plant-1), marketable weight (13.0 kg plant-1), curd yield (37.6 tha-1) and stover yield (29.7 tha-1) were found from T4 which was statistically identical with or followed by T8 and T5. From the experiment it was found that vermicompost was better that conventional compost in combination with chemical fertilizers.

This study aimed to determine the effect of the bioactive compost (arkoba) coconut shell charcoal on the growth and the yield of rice plants (Oryza sativa L.) on alluvial soil. The research was conducted in Mulia Baru Sub-District, Delta Pawan District, Ketapang Regency. This study occurred for four months, starting from February 2018-May 2018. The study used a Completely Randomized Design (CRD) with a dose of coconut shell bioactive compost charcoal treatment using six treatment levels, repeated four times where each replication consisted of 3 plant samples. With the result with 6 x 4 x 3 = 72 plants. The treatment was a0 = without giving ARKOBA, a1 = ARKOBA with a dose of 25 g / polybag (5 tons / ha), a2 = ARKOBA with a dose of 50 g / polybag (10 tons / ha), a3 = ARKOBA with a dose of 75 g / polybag (15 tons / ha), a4 = ARKOBA with a dose of 100 g / polybag (20 tons / ha), a5 = ARKOBA with a dose of 125 g / polybag (25 tons / ha). The parameters observed in the study were: plant height (cm), number of clump tillers (tillers), dry paddy grain weight (g), the weight of 100 grains of clump grain (g). The results showed that the dose treatment of coconut shell bioactive compost charcoal had a very significant effect on the variables, which is plant height, number of tillers, dry paddy grain weight and weight of 100 grains of dry grain. Treatment level a3 gave the best results on all variables observed plant height 88.88 cm, the number of tillers was 28.33 tillers, dry paddy grain weight was 20.52 g, and the weight of 100 dried grain seeds was 2.52 g.
