Media contaming cotton gin trash compost, pear. and perlite were evaluated for production of bell pepper, broccoli, and cabbage transplants. Media treatments were 0:5:5; 1:4:5; 2:4:5; 3:2:5; 4:1:5; and 5:0:5 compost, peat, perlite, respectively (v/v). Separate tests were conducted for each crop. `Jupiter' pepper, `Packman' broccoli, and `Grand Slam' cabbage were seeded in 96-cell plastic trays (cell volume =39cm3). Plant height, stem diameter, and shoot and root dry weight were recorded five weeks after seeding bell pepper and broccoil, and six weeks after seeding cabbage. Pepper, broccoli, and cabbage transplants grown in media containing cotton gin trash compost had greater plant height, stem diameter, and shoot and root dry weight than transplants grown in the medium without compost as a component. The growth response to percent of compost was primarily linear.

Tomato transplants were grown in plastic foam trays floated in nutrient solutions using a system adapted from tobacco transplant growers. Nutrient solutions were compared which contained equivalent amounts of nitrogen and potassium and either 35 or 70 mg·liter-1 phosphorus (P). Growing media tested were 1) Jiffy-Mix*, 2) Pro-Mix®, 3) horticultural vermiculite, or 4) perlite. The higher P rate caused increases in stem diameter, and in plant fresh and dry weight. Plant height, root dry weight and leaf area were not affected by P rate. Transplants grown in Pro-Mix® had significantly greater plant height and stem diameter than other media. Leaf area, and plant fresh and dry weight did not differ between Pro-Mix* and Jiffy-Mix@. Vermiculite and perlite produced smaller tomato transplants and should not be considered when using this production system.

Controlling plant height is an important practice in the ornamental plant industry. With high cost of growth regulators and concern about their environmental aspects and health of workers, alternative ways of controlling growth may be advantageous. Objective was to determine effect of photoselective shadecloth and plastic film on growth of `Barbara', `Shasta', and `Chesapeake' mums under supplemental lighting. In experiment 1, `Barbara' plants (two and four weeks old) were placed under either wide spectrum fluorescent lamps and incandescent light bulbs (control) or lights covered with photoselective shadecloth. In experiment 2, 3-week-old `Shasta' and `Chesapeake' plants were placed under lights or lights covered with photoselective plastic film. Effect of shadecloth differed with age of `Barbara' plants. For 1-month-old plants placed under lights, stem diameter, stem dry weight, and root dry weight were reduced under shadecloth compared to control. No differences were observed for plant height, pot height, leaf number, leaf area/plant, and leaf dry weight. For 2-week-old plants, leaf number, leaf area/plant, leaf dry weight, and stem dry weight were less under shadecloth than control. No effects on plant height, pot height, stem diameter, and root dry weight were observed. Plastic film reduced plant height and pot height for `Shasta' and `Chesapeake' plants and reduced stem dry weight and total plant dry weight for `Shasta'. No differences were seen for other growth measurements. This study indicated photoselective shadecloth did not control height of `Barbara' and its effect on growth was influenced by plant age. Photoselective plastic film controlled height of `Shasta' and `Chesapeake' and offers an alternative method for growth control of mum plants.

Abstract Growth of perennial quaking grass (Briza media L.), ‘Red Baron’ Japanese bloodgrass (Imperata cylindrica (L.) Beauv. ‘Red Baron’), river oats (Chasmanthium latifolium (Michx.) Yates), ‘Hameln’ dwarf fountain grass (Pennisetum alopecuroides (L.) Spreng. ‘Hameln’), and ‘Big Blue’ monkeygrass (Lirope muscari (Decne.) L.H. Bail. ‘Big Blue’) in 0%, 30%, or 60% shade was evaluated in container and in-ground experiments conducted over two growing seasons. Shade intensity did not affect plant height of any species grown in containers in 1997 or those grown in the ground that were planted and harvested in 1998. In 1997, width of containerized perennial quaking grass increased and width of containerized dwarf fountain grass decreased with increasing shade. In 1998, width of containerized Japanese bloodgrass increased and width of containerized dwarf fountain grass decreased with increased shade. Container-grown river oats shoot and root dry weight increased with shade intensity in 1998. Root to shoot (R/S) ratio decreased linearly with shade intensity for containerized river oats in 1997. Height of in-ground Japanese bloodgrass was not affected by shade intensity at any harvest time; however, height of perennial quaking grass increased and height of river oats and monkeygrass decreased as shade intensity increased regardless of harvest time. Few differences in plant width among shade treatments occurred for in-ground plants. Shoot dry weights for in-ground plants generally decreased with increasing shade intensity. Climatic differences may account for the variability in plant growth between the two years of the study.

ABSTRACT Rhizobacteria have a wide range of plant growth-promoting mechanisms of action, making them an alternative and/or complementary biological input for chemical fertilizers. In this respect, the present study aimed to assess growth and nitrogen accumulation in maize plants as a function of Azospirillum brasilense, Bacillus subtilis, zinc and nitrogen application at sowing. The experiment with the ‘AL Bandeirante’ maize variety was conducted in a greenhouse, using a completely randomized design. The treatments were arranged in a 2 x 2 x 2 x 2 factorial scheme, with six repetitions, considering the presence and absence of Azospirillum brasilense (5 g kg-1), Bacillus subtilis (5 mL kg-1) and zinc (20 g kg-1) in the seeds and addition or not of nitrogen (30 kg ha-1) to the soil. The variables assessed were plant height, stem diameter, leaf, stem, shoot, root and total dry weight, and shoot nitrogen content. Nitrogen fertilization in the absence of zinc increased shoot and total dry weight as well as shoot nitrogen content. Zinc applied to the seeds improved the total and stem dry weight of maize plants in the absence of Bacillus subtilis. Inoculation with Azospirillum brasilense and Bacillus subtilis increased the stem diameter and shoot nitrogen content of maize plants when nitrogen fertilization was not performed at sowing. There was no isolated or interaction effect between factors for plant height and root dry weight.

This study was aimed at assessing the growth and production of celery plants grown with various compositions of N,P and K fertilizer and compost. The study was done at the Trial Farm of Faculty of Agriculture, Djuanda University, Bogor fiom September to November 2015. A completely randomized design with two factors was used. The factors consisted of compost rate and N,P and K fertilizer rate. Compost was given in four levels, namely no compost (0% R), 26.3% gcompost/plant (50% R), 52.5 g compost/plant (100% R), and 78.7 g compost/plant (150% R). N, P and K fertilizer was given in five levels, namely no fertilizer (0% R), 4 g Urea, 0.3 g SP-36, 0.2 g KCl (25% R), 0.9 g Urea, 0.6 g SP-36, 0.4 g KCI (50% R), 1.3 g Urea, 0.8 g SP-36, 0.6 g KCl (75% R), and 1.7 g Urea, 1.1 g SP-36, 0.8 g KCl (100% R). All fertilizers were administered gradually at the time of planting and 2 weeks after planting. Three replicates were allocated into each treatment making up 60 experimental units. Results showed that celery plants given synthetic fertilizer at 100% R had higher plant height, number of leaves, number of seedlings, harvest fresh weight (g), saleable fresh weight (g), root biomass (g), and root dry weight (g) than those treated with no fertilizer (0% R). Plants treated with 150% compost had higher plant height, number of leaves, harvest fresh weight (g), saleable fresh weight (g), root length (cm), and root dry weight (g) than those treated with no fertilizer (0% R). Thus the best celery growth and production in this study was obtained on plant 150% R compost   and 100% R synthetic fertilizer nourished.Key words: celery, compost, N, P, K fertilizer, harvest flesh weight

The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers.

Pot experiments were conducted during T. aman 2001 and 2002 (wet season) at Bangladesh Rice Research Institute (BRRI) in net house. Hybrid variety Sonarbangla-1 and inbred modern variety BRRI dhan-31 were used in both the seasons and BRRI hybrid dhan-l was used in 2002. The main objective of the experiments was to compare the growth and yield behaviour of hybrid and inbred rice varieties under controlled condition. In 2001, BRRI dhan-3l had about 10-15% higher plant height, very similar tillers/plant, 15-25% higher leaf area at all days after transplanting (DAT) compared to Sonarbangla-1. Sonarbangla- 1 had about 40% higher dry matter production at 25 DAT but had very similar dry matter production at 50 and 75 DAT, 4-11% higher rooting depth at all DATs, about 22% higher root dry weight at 25 DAT, but 5-10% lower root dry weight at 50 and 75 DAT compared to BRRI dhan-31. The photosynthetic rate was higher (20 μ mol m-2/sec-1) in BRRI dhan-3l at 35 DAT (maximum tillering stage) but at 65 DAT, Sonarbangla-l had higher photosynthetic rate of 19.5 μ mol m-2 sec-1. BRRI dhan-3l had higher panicles/plant than Sonarbangla-1, but Sonarbangla-1 had higher number of grains/panicle, 1000-grain weight and grain yield than BRRI dhan-31. In 2002, BRRI dhan-31 had the highest plant height at 25 DAT, but at 75 DAT, BRRI hybrid dhan-l had the highest plant height. Sonarbangla-1 had the largest leaf area at 25 and 50 DAT followed by BRRI dhan-31, but at 75 DAT, BRRI dhan-31 had the largest leaf area. The highest shoot dry matter was observed in BRRI dhan-31 followed by Sonarbangla-1 at all DATs. Sonarbangla-1 had the highest rooting depth and root dry weight at all DATs. BRRI dhan-31 gave the highest number of panicles/plant followed by Sonarbangla-I, BRRI hybrid dhan-l had the highest grains/panicle followed by BRRI dhan-31 and Sonarbangla-I had the highest 1000-grain weight followed by BRRI dhan-31. The highest amount of grains/plant (34.6 g) was obtained from BRRI dhan-31. Key Words: Shoot dry matter; root dry weight; leaf area; photosynthesis; grain yield.

This research focuses on studying the effects of biochar on acidic soil nutrient, soybean production, root and plant height,using the method of pot plant simulation for soybean cultivation patterns in three ridging test. Biochar was applied for pot with set 0, 1, 5, 10, 15, 20, 25t hm-2. Biochar, diammonium hydrogen phosphate, urea and potassium chloride were fully mixed then sampled on soybean clover stage (V3), full bloom stage (R2) and the early mature stage (R7).This research examined the soybean root index. At the early mature stage (R7), soil samples were blown dry and examined chemical index. During the mature period (R8), we examined the yield and plant height. The results showed that, with the increase of the content of the biochar, available potassium，and organic matter was increased significantly, increasing 77.69mgkg-1, and 7.56gkg-1 compared with control respectively. The root dry weight, main root length, lateral root number, total length, lateral root number, root dry weight of the maximum was respectively increased by 80.85%, 100%, 33.86%, 167.74%, 26.31% and 80.41% than control in early mature stage. The yield increased by 35.97% compared with control.
