An experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during  the period from November 2010 to January 2011 to study the effects of cowdung and potassium on growth and yield  of Kohlrabi. The experiment consisted of three levels of cowdung (0, 20 and 40 t/ha) and four levels of potassium (0,  20, 50, 80 kg /ha). The experiment was laid out in randomized complete block design with three replications. All the  parameters were significantly influenced by application of cowdung and potassium. The highest plant height (44.65  cm), number of leaves per plant (12.11), length of largest leaf (37.54 cm), and breadth of largest leaf (18.66 cm) were  obtained from the highest dose of cowdung and potassium applied (40 t cowdung + 80 kg K/ha) while the lowest  plant height (33.64 cm), number of leaves (9.01), length of largest leaf (27.94 cm), and breadth of largest leaf (11.00  cm) were obtained from control treatment combination. The highest fresh weight of leaves (49.33 g), fresh weight of  knob (328.66 g) and fresh weight of roots (66.55 g) per plant were also recorded under the treatment combination of  40 t cowdung + 80 kg K/ha, while the lowest fresh weight of leaves (22.11 g), fresh weight of knob (136.00 g) and  fresh weight of roots (23.33 g) were obtained from control treatment combination. Similarly, the dry weight of leaves  (19.34%), knob (15.19%) and roots (32.75%) were highest under the same treatment combination of 40 t cowdung +  80 kg K/ha and the lowest dry weight of leaves (11.71%), dry weight of knob (7.38%) and dry weight of roots  (15.29%) were obtained from control treatment combination C0K0. The marketable yields of knob per plot (7.86 kg)  and per hectare (39.58 tons) were also the highest under the treatment combination 40 t cowdung/ha and 80 kg  potassium per hectare.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12035   J.

The study was designed to improve the quality of the SBP as milled cane planting material by improving the early growth of plants. Research carried out gradually implemented in the Indonesian Sugar Plantation Research Center (P3GI) Pasuruan, using two varieties of sugarcane are varieties Bululawang and PS 862 with numbers 7-16 buds. Germination (%), was observed on the 15th day after planting (DAP) and the growth of the plant include: plant height, number of leaves, leaf area, as well as the production of biomass include: Dry weight (DW) and fresh weight (FW) plant organs (leaves, stems, and roots). Fresh Weight (BS) and Dry Weight (BK) total crop. The results showed the top eye numbers (7,8,9,10) for both varieties provide the same germination potential (> 70%). But the number of buds bottom (11,12,13,14,15,16) Bululawang varieties give a lower percent germination than varieties of PS 862. At PS 862 varieties buds numbers 8 and 9 can generate over 95 percent germination %. Number eye affects plant growth in polybag components which include plant height, leaf area and the number of leaves and observation of the biomass production shows the influence of the number of eyes. These parameters indicate a decrease in the number and size of the eyes of the lower numbers. While the diameter rod eye development is not affected numbers. PS 862 varieties showed faster growth than Bululawang varieties. However, exposure to biomass production, Bululawang varieties showed higher yields than at PS 862 varieties.

Penelitian ini bertujuan yang menguji Perbandingan pertumbuhan vegetatif tanaman cabai merah (capsicum Annuum L.) akibat Pemberian Komposisi PGPR (Plant Growth-Promoting Rhizobacteria) yang perbeda. Pertumbuhan tanaman diukur berdasarkan tinggi tanaman, jumlah daun, volume akar, berat basah dan berat kering tanaman. Hasil penelitian menujukkan bahwa PGPR dapat meningkatkan tinggi tanaman, jumlah daun, volume akar, berat basah dan berat kering tanaman cabe.Tinggi tanaman terbaik setelah diperlakuan selama 28 hari adalah dengan pemberian PGPR disertai dengan pemberian pupuk kandang dengan tinggi (24.44 cm), yang diikuti oleh pemberian PGPR + kompos dengan tinggi (22.04 cm), dan pemberian PGPR + NPK dengan tnggi tanaman 19.68 cm . Volume akar akan lebih tinggi bila diberikan PGPR yang ditambah dengan pupuk kandang , atau kompos maupun NPK, tetapi tdak berbeda hasilnya bila hanya diberikan PGPR saja. Jumlah daun dapat ditingkatkan bila diberikan PGPR yang ditambah dengan pupuk kandang, atau kompos maupun NPK. Pemberian PGPR + NPK tidak memberikan jumlah daun yang berbeda dengan pemberian PGPR saja.Berat basah akan meningkat bila diberikan PGPR saja maupun ditambah dengan pemberian pupuk kandang, atau kompos maupun NPK. PGPR ditambah dengan pupuk kandang maupun kompos memberikan dampak yang sama terhadap berat basah.Berat kering akan meningkat bila diberikan PGPR saja maupun ditambah dengan pemberian pupuk kandang, atau kompos maupun NPK. PGPR ditambah dengan pupuk kandang maupun kompos memberikan dampak yang sama terhadap berat basahThis study aimed to examine the comparison of vegetative growth of red chili (capsicum Annuum L.) due to the administration of different PGPR (Plant Growth-Promoting Rhizobacteria) Composition. Plant growth was measured based on plant height, number of leaves, root volume, wet weight and dry weight of the plant. The results showed that PGPR can increase plant height, number of leaves, root volume, wet weight and dry weight of chilli plants. The best plant height after being treated for 28 days is by giving PGPR accompanied by administering manure with height (24.44 cm), followed by by giving PGPR + compost with a height (22.04 cm), and giving PGPR + NPK with a plant height of 19.68 cm. Root volume will be higher if given PGPR added with manure, or compost or NPK, but the results are not different if only given PGPR. The number of leaves can be increased if given PGPR added with manure, or compost or NPK. Provision of PGPR + NPK does not provide a number of leaves that are different from the administration of PGPR alone. Wet weight increased when given PGPR alone or added with manure, or compost or NPK. PGPR added with manure or compost gives the same effect on wet weight. Dry weight will increase if given PGPR alone or added with manure, or compost or NPK. PGPR coupled with manure or compost has the same effect on wet weight
