Purpose. Jute mallow (Corchorus olitorius L.) is a mucilaginous vegetable and fiber crop cultivated in the tropics, where catnip (Nepeta cataria L.) and Mexican sunflower (Tithonia diversifolia L.) are common weeds. Hence, the study investigated the growth, yield, and nutrient level of jute mallow in weed-free, catnip, and Mexican sunflower environments. Methods. The study involved two screen-house experiments in a Completely Randomized Design (CRD) with six replications. The treatments were 0 (control), 2, 4, 6, 8, and 10 weed plants per pot in both experiments. These are 0, 100, 200, 300, 400, and 500 weed count per square meter equivalent, based on the surface area of the pots used. Mexican sunflower and catnip plants interacted with jute plants in the first and second experiments, respectively. Growth parameters of jute mallow were recorded weekly from 5 to 8 weeks after sowing (WAS), and harvesting was done at 8 WAS. The proximate composition of jute was evaluated using standard procedures outlined by AOAC. The data collected were subjected to analysis of variance (ANOVA), and means were separated using Duncan Multiple Range Test (DMRT) at P < 0.05. Results. Catnip and Mexican sunflower negatively impacted the morphological features of jute mallow from 100 plants per square meter upwards. Catnip and Mexican sunflower, at 300 and 100–500 plants per square meter, respectively, reduced the dry weight of jute mallow. The crude protein content of jute mallow was also lessened by Mexican sunflower at some point. Conclusions. The study recommends that the density of catnip and Mexican sunflower plants interacting with jute mallow should be maintained below 100 plants per square meter to prevent yield loss.

A pot experiment was set up using completely randomized design (CRD) to compare the influences of different commonly available organic manures in the markets of Dhaka, Bangladesh on the growth parameters and nutrient contents in Mint plants (Mentha sp.). Eight different manures were used as treatments for the comparison, viz. ACI, Alo, Annopurna Vermicompost, Cow dung, Kazi, Mazim, Modern Vermicompost and Trichocompost GBD, along with a control, taking three replications of each treatment. After 2.5 months (75 days) the plants were harvested. Trichocompost GBD showed the highest average number of leaves (130.33 plant-1), plant height (27.67 cm plant-1), number of branches (11.00 plant-1) and number of stolons at harvest (1.67 plant-1). The maximum average single leaf area (2.01 cm2 plant-1) and fresh weight (1.68 g plant-1) were observed in Kazi. ACI was observed to have the highest dry weight (0.26 g plant-1), whereas cow dung had the longest root (8.57 cm plant-1). Nutrient accumulation in leaf and stem exhibited the highest N in ACI, highest P and K in Alo, and highest S in Kazi. Correlation analysis of the explored traits with nutrient concentration of plant shoots was performed to elucidate the impact of plant nutrient contents on the analysed parameters. J. Biodivers.

The study compares the growth, yield, and proximate composition of Amaranthus hybridus, Amaranthus cruentus, and Amaranthus deflexus, grown with poultry manure and NPK in relation to the unfertilized soil of Ilorin, Nigeria. Viable seeds of the Amaranths raised in nursery for two weeks were transplanted (one plant per pot) into unfertilized soil (control) and soils fertilized with either NPK or poultry manure (PM) at 30 Kg ha−1 rate arranged in randomized complete block design with four replicates. Data were collected on plant height, stem girth, number of leaves, leaf area, and number of branches from 1 week after transplanting (1 WAT). Fresh weight, dry weight, and proximate composition were determined at 6 WAT. Except for the length, breadth, and number of leaves, the order of growth parameters and yield in the three Amaranthus species was NPK > PM > control. NPK grown Amaranthus species had the highest protein while PM-grown vegetables had the highest ash content. Crude fibre in A. cruentus grown with PM was significantly higher than NPK and the control. The NPK treatment of A. hybridus and A. deflexus had the highest crude fibre content. NPK and PM favoured growth and yield of the Amaranthus species but influenced proximate composition differently.

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

The response in growth and development of seedlings of Dialium guineense to different potting media was studied in the screen house. Five potting media: River sand (Rs), Top soil (Ts), Poultry manure (Pm), Rice husk (Rh) and Oil palm refuse bunch (OPRB) were used. They were evaluated as sole treatments and in combination with river sand (Rs) in different ratios (1:1, 1:2, 2:5 and 5:2) respectively. Altogether, twenty one (21) potting media types were evaluated. The experiment was laid out in a completely randomized design (CRD) in three replications. Data were collected on monthly basis for plant growth parameters, while shoot and root dry weight were measured at the end of the experiment. On the average the seedlings of D. guineense responded best on the Rs + Ts 1:2 growth medium in number of leaves (16.67), stem girth (0.31 cm), number of nodes (11.67), shoot dry weight (1.24 g) and root dry weight (0.50 g). Rs + Ts 1:2 was followed by Rs + Pm 1:1 and Ts sole respectively with respect to the growth parameters evaluated and were not significantly (p 0.05) from one another, but were significantly (p < 0.05) different from other media and their combinations with river sand.

To investigate the effect of nano-zinc fertilizer on growth, yield and mineral status of cotton plants grown under salt stress, a pot experiment was set up in the greenhouse of the National Research Centre. The treatments were as follows: (I) diluted seawater: 10% (S1), 20% (S2) and tap water as a control (S0), (II) 100 ppm (NZn1), 200 ppm (NZn2) nano-zinc and distilled water as a control (NZn0). Irrigation with 10 and 20% seawater decreased dry weight (DW) of leaves by 11.53 and 43.22%, while decreases in bolls were 15.50 and 71.65%, respectively. Except for root DW and top/root ratio, the measured growth parameters were increased as nano-zinc concentration increased. As for the interaction between treatments, the highest DW of stem, leaves and bolls resulted from the addition of NZn2 under normal condition, followed by NZn2 x S1 and the next was NZn2 x S2. The foliar application of 200 ppm nano-Zn led to mitigating the adverse effect of salinity and confirmed that diluted seawater could be used in the irrigation of cotton plant. However, phosphorus fertilizer should be added with nano-Zn application to avoid P/Zn imbalance. Some elements’ status and their ratios were recorded.

Inoculation of seven different crop plant species by Azospirillum brasilense Cd resulted in an increase in plant yield, as well as in changes in several other plant parameters, in tomato, eggplant, pepper, and cotton plants. Analysis of 56 different experiments revealed that the rate of success (positive plant response) ranged from 71 to 75 %. The dry weight of plants and yield responses ranged from significantly high yield increases to negligible or no response in similarly performed experiments. The average increases in yield in the positive response experiments were 30, 23, 18, and 16% for tomato, eggplant, pepper, and cotton, respectively. Significant earlier maturation was also detected in the four responding plant species. The response of other plant growth parameters varied between plant species. The level of root colonization by A. brasilense Cd was similar in all four plant species, i.e. root population size of 5 × 105 cfu/g fresh weight root. It is suggested that inoculation of noncereal crop plants by the cereal-root originate A. brasilense Cd is nonspecific with inconsistency in plant response to inoculation.

Tithonia (Tithonia diversifolia) has been known as shrubs having potential as a green manure crop. Its growth exceeding legume in poor soil nutrients is strongly influenced by mycorhyzosphere. This study tried to use infected root of tithonia as innoculant of arbuscular mycorrhizal fungus (AMF) on growth and yield of maize (Zea mays L.). The purpose of this research was to study the effect of a given amount of root of tithonia as AMF innoculants on the growth and yield of maize.  The study was designed in Completely Randomized Design (CRD) with 5 replicates. The treatment used in this experiment was amount of innoculum consisting of 4 levels: without innoculum (0 g), 10 g, 20 g, and 30 g of innoculum per pot.  The results obtained showed that tithonia roots infected with AMF could be used as innoculum.  It also caused plant height, dry weight of straw, and P- uptake by crops significantly increased. The use of 20 g of innoculum was the best treatment in this experiment which could increase the weight of dry maize straw to 69.67 g per pot which was significantly different from treatment without innoculation. At the same treatment was also found that the best nutrients (N, P, and K) uptake was determined on straw. Innoculation of AMF using tithonia roots affected the increase in frequency and intensity of infection and numbers of spores found in maize rhizosphere.Keywords: arbuscular-mycorrhiza, innoculation, maize, production, tithonia
