‘Big Beef’ tomatoes produced 2.68 kg/plant from a 72 day harvest period when they were grown in 0.35 liter aluminum beverage cans by a sub-irrigation hydroponic method. Tomatoes growing in net pots (70 ml) suspended by expanded polystyrene bead boards with a sub-irrigation method gave similar yields in one trial but lower yields in another trial than tomatoes growing in beverage cans. Tomatoes ...

Eight genotypes of lentil (Lens culinaris Medik.) were tested for bioaccumulation and transport of arsenic (As) in a pot experiment under controlled growth condition. Along with control (no As was added), plants were grown for 60 d in pot soil spiked with 100 mg As kg, added as Sodium arsenate. Significant (P < 0.05) variations among eight genotypes were observed in bioaccumulation and transpor...

Parthenium density and species richness were found to be more in non-invaded (N-I) sites as compared to invaded (I) sites of Jaunpur district. pH, OC and %N of the soil indicates that the plant survive naturally at higher level of salinity. In pot experiment, plant growth, proline content, TSS content, chlorophyll, N, P and K was not significantly affected up to 1% NaCl (w/w) over the control a...

A pot experiment was conducted to examine the effects of.various fertilizers on the dynamics of soil-borne DDTs and their subsequent impacts on DDTs uptake by a test plant. The results show that there was a significantly lower soil residual DDTs concentration in the iron-rich fertilizer-treated soil than in other fertilizer-treated soils. However, all the non-iron-rich fertilizers showed no sig...

The application of biochars to improve soils and to mitigate global climate change is a popular research area all over the world, although it is not a new topic. In our study, wood chips char (BC) and animal bone char (ABC) were applied. The pot experiments were conducted under laboratory conditions. 2 grams of rye-grass (Lolium perenne) were seeded into each pot. The following various soil par...

The heavy metal uptake of ten plant species was studied under different soil and climatic conditions. Effects of soil pH, temperature, plant species and phenophase on the heavy metal content of stems and leaves were determined in pot experiments. Plants and soil samples were collected from a lead/zinc mine ore (Gyöngyösoroszi, Hungary) and characterised by high contents of Pb, Zn, As, Cd, Cu. T...

Improvement in leaf hydraulics is directly related to the improvement of plant tolerance to drought stress. Therefore, a field and pot experiment was carried out to determine the type of genetic variability and selection of parental types on the basis of combining ability for leaf hydraulics. Genotypes showed similar performance in both experiments; higher values were shown by drought tolerant ...

this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

Wazirpur industrial area of Delhi generates a huge quantity of sludge per day, which is highly acidic in nature (pH 2.7 to 4.4) and contains macronutrients, micronutrients as well as toxic metals. A pot-culture experiment was conducted by taking the two soils (JNU and Chhattarpur) amended with sludge (0%, 10%, 20%, 30%), pretreated with lime (0%, 0.5% and 1%). Two wheat seedlings were planted p...
