Effect of Adding SAPs Polymers and Spraying With Organic Fertilizer on The Vegetative and Root Growth Characteristics of Lawns

Abstract The experiment was carried out in the fields of the Department of Horticulture and Landscaping, College of Agriculture - Anbar University for the period from 1/4/2020 to 31/1/2021 to experience the effectiveness of adding SAPs, spraying with organic fertilizers and the interaction between them in the vegetative and root growth characteristics of the lawn. The polymers were used in three concentrations (0, 20, 40) g kg-1 soil, while the organic fertilizer was in four concentrations (0, 0.5, 1, 1.5) ml.L-1. A factorial experiment was carried out according to a randomized complete block design (RCBD) with three replications. The results showed that the addition of polymers at the level of 40 g kg-1 soil had significant differences in the average plant density, root length, dry matter percentage and chlorophyll content in the vegetative group was 47.83 plant 100 cm-2, 25.20 cm, 36.85% and 89.36 mg g-1 for hot season and 29.17%, 36.19 m mg-1 for cold season. The high concentration of organic fertilizer 1.5 ml L-1 showed significant differences in plant density, number of branches in the crown area, root length, dry matter percentage and chlorophyll content in the vegetative group was 46.00 plant 100 cm-2, 9.10 branch plant-1, 25.14 cm and 36.41%, 87.80 mg g-1 for hot season and 29.04%, 33.99 mg g-1 for cold season. The interaction treatment between the level of application of polymers 40 g kg-1 soil and the treatment of adding organic fertilizer 1.5 ml L-1 showed significant differences in the number of branches, root length, dry matter percentage and chlorophyll content in the vegetative group was 9.83 branch plant-1, 27.36 cm and 39.65%, 99.31 mg g-1 for hot season and 33.44%, 42.10 mg g-1 for cold season.

Mungbean is one of the strategic annual food crops that needed by Indonesian people because of the high protein and minerals. Production of mungbean in Indonesia always decreases. Cultural improvements are needed to increase productivity i.e by appropriate fertilization and plant density. The experiment objective was to find out the optimum dosage of organic fertilizer and plant density for the growth and yield of mungbean. The experiment was carried out using factorial completely randomized design (CRD). The first factor treatments were organic fertilizer which consisted of 0, 5, 10, 15, and 20 ton ha-1, while the second-factor treatments were planted density which consisted of 1 and 2 plants in the hole. Organic fertilizer of 5 ton ha-1 gave the best result for plant height, number of branches, flowering age, number of pods, fresh weight and dried straw, weight of 100 seeds, number and weight of seeds, small of seeds number and P nutrient uptake of the plant. The 2 plants per hole gave the best result for branches number, pods number and number of small seeds. Application of 5 ton ha-1 organic fertilizer and 1 plant per hole gave better yield. No interaction of organic fertilizer and plant density to mungbean growth and yield.

The present study was undertaken with a view to study the effect of plant density on yield and yield attributes of two soybean varieties in kharif–II season. The experiment was conducted in kharif-II season 2012 at mymensingh with two soybean varieties, namely PB-1 (Shohag) and G-2 (Bangladesh soybean-4) and six plant densities, viz; 20, 40, 60, 80, 100 and 120 plants m-2 established using an equidistant (square) planting pattern of 22.4cm x 22.4 cm, 15.8 cm x 15.8 cm, 12.9 cm x12.9 cm, 11.2 cm x 11.2 cm, 10 cm x 10 cm and 9.1 cm 9.1 cm, respectively. The experiment was laid out in a split-plot design with varieties in main-plots and plant densities in sub-plots. The treatments were replicated three times. Increased plant density increased plant height, number of nodes plant-1, total dry matter, seed yield (1.02 t ha-1) and Stover yield (1.15 t ha-1) 80 to 100 plants m-2 and then decreased with increased plant density. Again increased plant density linearly decreased in number of branches plant-1, fertile pods plant-1, non-fertile pods plant-1, number of seeds plant-1, seed yield plant-1 and 100- seed weight up to 120 plants m-2 depending on variety and season. The study concludes that the highest yield of soybean in kharif –II season could be obtained from varietyPB-1 with a plant density of 100 plants m-2 and 80 plants m-2in G-2.

ABSTRACT The objective was to determine the growth and accumulation of macronutrients of two pineapple cultivars submitted to different concentrations of aluminum (Al). For this, a study was conducted in plastic pots containing 4 L of nutrient solution, in a randomized block design, in a 2 x 5 factorial scheme, corresponding to two pineapple cultivars (‘IAC Fantástico’ and ‘Vitória’) and five Al concentrations (0, 21.6, 43.2, 64.8 and 86.4 mg of Al plant-1), with four replicates. The following variables were evaluated: root length, dry matter of root, stem and leaf, stem diameter, number of leaves, chlorophyll content and accumulation of macronutrients at 60 days after treatment. The cv. ‘Vitória’ showed a linear decrease in chlorophyll content, root dry matter, root length and accumulation of N, P, K, Ca and Mg in most plant components promoted by the increase of Al concentration in the nutrient solution. The cv. ‘IAC Fantástico’ had lower total dry matter, stem dry matter, stem diameter and accumulation of N, Ca and Mg. However, the evaluated characteristics were not influenced by the increase of Al concentration, showing greater tolerance of this cultivar to Al in nutrient solution.

ABSTRACT This study aimed to evaluate the effect of seeding rates and nitrogen (N) fertilization on plant growth in soybean cultivar with indeterminate growth habit. Two experiments were conducted in the 2013/14 and 2014/15 growing seasons, in a complete block design with split-plot scheme and six replicates. Four seeding rates (150, 300, 440 and 560 000 viable seeds ha-1) and two N doses (0 and 45 kg ha-1) were allocated in the plots and subplots, respectively. The cultivar NK7059 RR was used. The following traits were assessed: leaf, stem and total shoot dry matter, leaf/stem dry matter ratio, stem and leaf N content, SPAD index, plant height, first pod height, number of branches per plant and grain yield. Soybean growth is not affected by the interaction of plant density and mineral N fertilization. Higher seeding rates increase plant dry matter in the initial development stages and reduce leaf/stem ratio and the number of branches per plant. The effects of N fertilization on soybean growth vary between growing seasons, but do not affect grain yield, even considering a wide range of seeding rates.

Refined nutrient delivery systems are important for environmentally friendly production of cut flowers in both soil and hydroponic culture. They have to be closely orientated at the actual nutrient demand. To solve current problems, express analysis and nutrient uptake models have been developed in horticulture. However, the necessity of relatively laborious analysis or estimation of model input parameters have prevented their commercial use up to now. For this reason, we studied relationships between easily determinable parameters of plant biomass structure as shoot height, plant density and dry matter production as well as amount of nitrogen removal of hydroponically grown year-round cut chrysanthemums. In four experiments (planting dates 5.11.91; 25.3.92; 4.1.93; 1.7.93) with cultivar `Puma white' and a fixed plant density of 64 m2, shoots were harvested every 14 days from planting until flowering, with dry matter, internal N concentration and shoot height being measured. For each planting date, N uptake (y) was closely (r2 = 0.94; 0.93; 0.84; 0.93, respectively) related to shoot height (x) at the time of cutting and could be characterized by the equation y = a * × b. In the soilless cultivation system, dry matter concentrations of N remained constant over the whole growing period, indicating non-limiting nitrogen supply. In agreement with constant internal N concentrations, N uptake was linearly related (r2 = 0.94 to 0.99) to dry matter accumulation. It is concluded that shoot height is a useful parameter to include in a simple model of N uptake. However, in consideration of fluctuating greenhouse climate conditions needs more sophisticated approaches including processes such as water uptake and photosynthetically active radiation.

Improving nitrogen use efficiency is a significant scientific problem to be solved. Two maize hybrids JD27 (Jidan 27) and SD19 (Sidan 19) were selected to study the effects of nitrogen levels on root characteristic parameters and plant dry matter accumulation, distribution and transportation. We set five different nitrogen levels, which were nitrogen deficiency (000N), low nitrogen (075N), medium nitrogen (150N), high nitrogen (225N) and excessive nitrogen (300N). The results showed that the root length and root surface area of JD27 were significantly higher than those of SD19 under 075N. With the increase of nitrogen levels, the root difference among varieties gradually decreased. The root length, projection area, total surface area and total volume reached the maximum values at silking stage. The average root diameter kept stable or decreased slowly with the growth stage. The dry matter accumulation of JD27 was higher than that of SD19 at all growth stages. Increasing the amount of nitrogen fertilizer can promote the transport of dry matter to grain and improve dry matter transport efficiency after anthesis. Under the treatment of medium and high nitrogen fertilizer, maize was easy to obtain a higher yield, but excessive nitrogen fertilizer inhibited the increase of yield. This study provides theoretical and practical guidance for maize production techniques.
