The potency of mexican sunflower extract as the replacement of manure and rice husk charcoal in banana seedling

In the nursery, media composition plays an essential role in the growth and development of plant seedlings. Extract of Mexican sunflower (Tithonia diversifolia) could be suitable for replacing organic manure and rice husk charcoal during the seedling phase. The purpose of this study is to examine the ability of Mexican sunflower extract to replace organic manure and rice husk charcoal as the source of nutrients for banana seedling. The study was arranged in a Completely Randomized Design with seven treatments and three replications. Extract of Mexican sunflower promotes plant growth (plant height, number of leaves, and leaf area), improves plant biomass, and improves soil chemical properties (pH (H2O), C organic, and total N). Application twice a week of Mexican sunflower into soil medium resulted superior in plant height, the number of leaves, leaf area, and total biomass of banana seedlings compared to other treatments. Extract of Mexican sunflower could replace organic manure and rice husk charcoal as the nutrient source in banana seedlings. AbstrakPada saat pembibitan, komposisi media memiliki peranan penting terhadap pertumbuhan dan perkembangan bibit tanaman.

Fall Dormancy

To quantify the influence of autumn (fall) dormancy (FD) on DM production and phenological development during the seedling phase, three lucerne genotypes with contrasting ratings were grown at Lincoln University, New Zealand. A dormant (FD2), a semi-dormant (FD5), and a winter-active (FD10) genotype were inoculated and sown at a rate of 290 plants/m2 on 8 October 2014. By the end of the seedling phase (15 January 2015) the FD10 genotype had produced 20% higher shoot yield and 17% higher root yield than the other two genotypes. The percentage of total biomass partitioned to roots (Proot) was 50% for all genotypes. Total plant biomass (root + shoot yields) was 6.55 t DM/ha for FD10 compared with 5.57 t DM/ha for FD 2 and FD5. Plant height at the open-flower stage was 39.5 cm for FD10 compared with 34.5 cm for FD5 and 33.5 cm for FD2. Maximum leaf area index was similar amongst genotypes at 2.5. However, individual leaf area was 142, 119 and 111 cm2/stem for FD10, FD5 and FD2, respectively. The phyllochron was 52oCd per primary leaf (base temperature of 1oC) and consistent amongst genotypes. The number of primary leaves and branches were also conservative at 17 and 14/shoot, respectively. Therefore, differences in shoot yield among these lucerne genotypes during the seedling stage were mainly due to differences in plant height and individual leaf area expansion per plant. This led to greater light interception and therefore higher total biomass accumulation for FD10 than for the other two genotypes. Keywords: alfalfa, autumn, Medicago sativa L., phyllochron

Experiments were conducted to evaluate drought tolerance under different levels of water stress in poplar trees. The cuttings of Populus deltoides L. (clone Kranti) were exposed to four different watering regimes (100, 75, 50 and 25% of the field capacity) and changes in physiological parameters related with drought tolerance were recorded. Drought treatments (75%, 50% and 25% FC) decreased net photosynthetic rate (Pn), transpiration rate (E), chlorophyll fluorescence (Fv/Fmax), plant height, number of leaves, specific leaf area (SLA), leaf area index (LAI) and total biomass content in all the three watering regimes compared to control (100% FC). Cuttings were showed poor performance with increasing levels of drought stress. Severity were observed in Pn, E, Fv/Fmax, plant height, stem diameter, leaf area and number of leaves, SLA, LAI and total biomass content with increasing levels of water stress. Decreased CO2 assimilation and transpiration rate due to instantaneous closure of stomata to protect the plants against hazardous effects of water stress leads to overall decrease in biomass of cuttings with 60 days water stress treatments. By visualizing the results, we can say that Scarcity of water is a severe environmental constraint to plant productivity. Drought-induced loss in plant productivity, since both the severity and duration of the stress are critical. Secondly, we can emphasise with our experiment that poplar plants can maintain their better growth and biomass only up to 75-50% of FC after that stress shows its severity so much that the aim of plants is only to survive and biomass maintenance become vague.

Organic fertilizers have an important role in the success of vegetable cultivation. Marine mud contains a lot of nutrients and organic matter, so it is useful for improving degraded soils in the short term and a source of nitrogen and minerals (especially Ca and Mg) in the long term. This study aimed to examine and explain the effect of doses of cow dung fertilizer and marine mud, for the growth and yield of spoon mustard (Brassica rapa L). This research was conducted at the Plastic House of the Faculty of Agriculture, Pattimura University, from June to August 2018. The experiment in this study was a factorial experiment in a completely randomized design with two factors. The first factor was sea mud from Tulehu Village (L) with 4 levels, namely: without sea mud (control), 100 g, 200 g and 300 g per kg of soil. The second factor was cow manure (K) with 4 levels, namely: without cow manure (control), 5 g, 10 g. and 15 g per kg of soil. The variables observed included plant height, leaf number, leaf area, plant biomass fresh weight, crown fresh and root fresh weight. Data were analyzed using Analysis of Variance (ANOVA) and further test using Duncan's test at 0.05 level. The results showed that the sea mud treatment had a very significant effect on the variables of plant height (3, 4 and 5 weeks after planting, WAP), leaf number (4 and 5 WAP), leaf area, plant biomass weight and plant crown weight, number of leaves (3 WAP) and root weight, but had no significant effect on plant height at age (1 and 2 WAP), and number of leaves (1 and 2 WAP). The treatment of cow dung fertilizer had a very significant effect on the variables of plant height (2, 4 and 5 WAP), number of leaves (3 and 5 WAP), plant biomass weight and plant crown weight, a significant effect on plant height (3 WAP), leaf number (4 WAP), but had no significant effect on plant height (1 WAP), leaf number (1 and 2 WAP), leaf area and root weight of plants. The interaction between the treatment of marine mud and cow manure gave a very significant effect on plant height (4 and 5 WAP), but there was no interaction on the other observation variables.

A research on the effect of photosynthetic active radiation (PAR) on the growth of green mustard plants has been conducted. The radiation source used is sunlight. Samples have been grouped as a sample which treated by red filter (P1), by orange filter (P2), by purple filter (P3), by green filter (P4), by blue filter (P5) and a sample without filter as a control (P0). Each sample consisted of four plants. The planting was carried out using polybags with compost media. Observations were made from the nursery phase to the slow vegetative phase (day 3rd, when all plants had grown shoots until day 63rd of the harvest). Parameters measured include light intensity, plant height and number of leaves. Measurement is done every three days. Also it measured plant biomass on the last day of observation (63rd day). The results showed that the intensity of each sample had an impact on the harvest. The best growth rate is obtained in P2, both in the nursery phase and fast vegetative phase i.e. 0.119 cm/day and 0.194 cm/day, respectively. While the highest growth rate was obtained in the P3 sample, namely the slow vegetative phase (0.035 cm/day). Overall the best planting results were obtained in P2 samples with plant height of 23.18 cm, number of leaves of 12 strands and plant biomass of 33.56 g.

Tanaman nilam tumbuh dan berproduksi dengan baik pada daerah dengan curah hujan relatif tinggi dan merata sepanjang tahun. Tanaman dalam kondisi kekurangan air terus menerus akan mengalami strcs air dan berpengaruh terhadap proses fisiologis, menurunkan permukaan trans- pirasi, luas daun menurun, dan mempercepat dcfiidrasi protoplasma. Penelitian pengaruh ketersediaan air terhadap petumbuhan dan produksi 2 (dua) klon nilam dilakukan di rumah kaca Instalasi Penelitian Cimanggu, Balittro Bogor mulai bulan Nopember 1999 sampai dengan Mei 2000. Penelitian ini betujuan untuk mengetahui pengaruh ketersediaan air terhadap partumbuhan dan produksi dua klon nilam (klon Sidikalang dan klon Situak) sekaligus diamati pengaruhnya terhadap kadar dan kualitas minyak nilam (rendemen, warna dan kandungan patchouly alkohol). Percobaan dilakukan dalam polibag menggunakan tanah kering jenis latosol Cimanggu Bogor yang diaduk dengan pupuk kandang sapi (3:1) sebanyak 10 kg/polibag disusun menggunakan rancangan factorial (dua faktor) dalam rancangan acak lengkap (RAL), diulang 3 kali. Ukuran plot 8 polibag/ perlakuan. Faktor pertama : klon nilam terdiri dari 2 jenis (K) yaitu : Kl = klon Sidikalang dan K2 = klon Situak. Faktor kedua: tingkat ketersediaan air (A) 4 taraf yaitu Al = 25% kapasitas lapang, A2 = 50% kapasitas lapang, A3 = 75% kapasitas lapang, dan A4 = 100 % kapasitas lapang. Peubah yang diamati meliputi persentase tumbuh tunas, tinggi tanaman, luas daun, bobot daun basah dan bobot daun kering, kadar minyak digambarkan dari rendemen dan kualitas minyak (wana dan kandungan patchouly alkohol). Hasil penelitian menunjukkan bahwa untuk jumlah tunas tidak ada interaksi antara tingkat ketersediaan air dan klon yang diuji, tetapi untuk jumlah daun ada interaksi. Tingkat pemberian air 75% kapasitas lapang (KL) secara keseluruhan memberikan pertumbuhan optimum bagi kedua klon, kecuali untuk parameter jumlah daun. Pada klon Situak. tingkat pemberian air 100% KL yang memberikan jumlah daun terbanyak. Perlakuan ketersediaan air 100% KL pada klon Sidikalang memberikan bobot daun kering tetinggi dibanding perlakuan lainnya, sedang untuk klon Situak, ketersediaan air pada taraf 75% KL memberikan bobot daun kering tetinggi. Rendemen minyak klon Situak dengan tingkat ketersediaan air 25% KL tertinggi (4.0%) dengan wana minyak kuning muda tcrang, diikuti tingkat 50% KL (3.0%) dengan wana minyak kusam/kemh. Kandungan patchouly alkohol klon Situak rata-rata (30%) lebih baik daripada klon Sidikalang, diperoleh dari perlakuan ketersediaan air 25% KL. Dapat disimpulkan bahwa untuk memperoleh petumbuhan dan produksi yang tinggi, ketersediaan air dalam tanah diperlukan antara 75 - 100% KL. Namun, untuk mendapatkan kandungan patchouly alkohol tinggi ketersediaan air yang dibutuhkan lebih rendah yaitu 25 % - 50%) KL.Kata kunci: Nilam, Pogostemon cablin, ketersediaan air, petumbuhan, produksi ABSTRACTThe effect of water availability the growth and production of two patchouly clones Patchouly plant grows and produces very well in the area with high and everly rain fall through the year. Plants with continuous shortage of water would face water stress and affect physiologis process, transpiration surface, leaf area and protoplasmic dehydration. Several levels of water needs were tested in this experiment, which was carried out in a glass house of Cimanggu Installation, Indonesian Spice and Medicinal Crops Research Institute, Bogor, rom November 1999 to May 2000. The objective was to find out the effect of water availability on two clones of patchouly growth, production and oil content (rendement, colour and patchouly alcohol). The experiment was conducted in polybags using Cimanggu Latosol soil mixed with cow dung (3:1), 10 kg/polybag, arranged in a factorially completely random design with 3 replications. Plot size was 8 polybag/treatment. The first factor was two clones of patchouly : K, = Sidikalang and K2 = Situak. The second factor was 4 levels of water availability: 2J% (A,), 50% (A2). 75% (A,), and 100% (A,) ield capacity (FC). Variables observed were percentage of shoot growth, plant height, leaf area, fresh weight and dry weight, oil content (rendement, colour and patchouly alcohol). The result showed that there was no interaction between the two factors for number of shoots. Clone of Sidikalang had higher plant height than that of Situak. The water availability of 75% (FC) gave optimum growth for the two clones, except the number of leaves. For Situak the water avaibility of 100% (FC) gave the highest number of leaves. For Sidikalang the water availability of 100% gave the highest dry weight of leaves. Oil rendement for Situak with 25% FC was the highest (4.0) with bright yellow colour. The content of patchouly alcohol for Situak was higher than that of Sidikalang (30%). Therefore, it can be concluded that to obtain the optimum growth and the higest production it needed 75 - 100% (FC) water availability, while for high patchouly alcohol content, it needed buzer the water availability, i.e. 25-50% (FC).Key words: Patchouli, Pogostemon cablin, water level, growth, production

Field trials were carried out during 2018 and during 2019 dry season periods at Federal College of Forestry and Mechanization Afaka Kaduna, located between latitude 10° 35”N and longitude 007° 21”E at altitude 644 m above sea level, to determine the effects of organic manure source and weeding frequencies on growth parameters of jute mallow (Corchorus olitorious). The experimental treatments consists of ten combinations of poultry manure + weed free, cow dung + weed free, goat dropping + weed free, poultry manure + weeding at 2 WAT, cow dung + weeding at 2 WAT, goat dropping + weeding at 2 WAT, poultry manure + weeding at 4 WAT, cow dung + weeding at 4 WAT, goat dropping + weeding at 4 WAT and no organic manure application + no weeding which were laid out in a randomize complete block design (RCBD) and replicated 3 times The growth parameters observed and measured were crop vigour score, plant height, shoot diameter, number of leaves and number of primary branches. Result of the study showed that at harvest (8 WAT) all the treatments significantly affected the vigour of jute mallow crop and gave comparable score than the least observed with no nutrient + no weeding as control. The result revealed that plant growth at harvest exhibited significantly taller plant with application of poultry manure + weeding at 2 WAT. In conclusion the result obtained from the study showed that poultry manure at 4 tons /ha + weeding at 4 WAT resulted in taller plant height, wider shoot diameter, increased number of leaves, number of branches than all other treatment due to lower weed infestation, it is therefore recommended as the best treatment combination to obtained the best growth rate of jute mallow.
