The T1/2 of Hexythiazox was calculated using Hoskins formula (Hoskins1961). The residual half life values were found to be in the range of 1.42 to 2.13 for recommended dose (T1) and 1.84 to 2.47 days for double the recommended dose (T2) respectively for all four locations. The soil sample was collected on 10th day after the application of the chemical. Hexythiazox residue was found below quantification level (0.03 ug/ml) in soil for all the four locations. Abd-Alrahman SH (2012) in a trial of Hexythiazox in bean-pods found that the initial deposit of Hexythiazox was 0.76 ug/g and the half life value of Hexythiazox 2.70 days.
Flowering per cen was calculated by number of flower buds over 100 total buds on a shoot. Initial fruit set was calculated after three weeks of flowering. Final fruit set percentage of replicated trees was studied after 60 days of fruit set and calculated by the following
The grass cutters were housed in a concrete cell measuring 200×80×40cm (length × breath height) which was disinfected one month before the arrival of the animals. The floor of the cell was made of solid concrete, temperature within the cells were within the range of 27-30℃ during the period of experiment. On introduction of the grass cutter the anti stress (strexia) was added into the drinking water. Feed intake and weights were recorded daily and weekly respectively throughout the experiment, which lasted for 60 days. Preparation of experimental diets Wild sunflower leaf meal was prepared by air drying wild sunflower strands harvested when the first inflorescence had opened in 50-80% of the plants; it is later spread on a concrete floor to air dry.
A field trial was made during November to March 2010-2011 and 2011-2012 at Central Research Farm, Gayeshpur, B.C.K.V. farm, Nadia, West Bengal to study the floral biology of two species Cucurbita moschata and C. pepo. One genotype each of both the species was chosen as the materials for the study. The study revealed that both species showed monoecious sex form. Using statistical analysis of mean and standard error it was found that it took lesser number of days for visible flower bud to opening of both male and female flower in C. moschata compared to C. pepo flower from the visible bud stage irrespective of the species.
The growth performance of tomato plants was evaluated in terms of shoot length (SL) and root length (RL) plant−1, shoot (SFW) and root fresh weight (RFW) plant−1, shoot (SDW) and root dry weight (RDW) plant−1 and area leaf -1. The leaf area was measured directly using a Leaf Area Meter (LI-COR Inc., USA). The area of three leaves (upper, middle, and lower) from each plant of the sample (consisting of five plants) was determined. 2.3.1. Determination of physio-biochemical characteristics of plants 2.3.2.
Plot sizes were 2m x 1.8m with 1m gap between plots. Total land area for the experiment was 20m x20m (400m2).The seedling spaced at 60cm x30cm with one plant per stand. Weed was controlled by the use of hoe as at when necessary while insect pest was controlled using Karate at the rate of 40ml to 20litre of water as at when needed. The plant were allowed to grow for 8 weeks after transplanting while the fertilizer treatments were applied a week after transplanting using ring method. The fertilizer treatments were: 0kg/ha (control) ,100,200,300 and 400kg/ha.
Ten to twenty explants were used per treatment in each replication. Observations were recorded on the frequency (number of cultures responding for multiple shoot proliferation and root development) and the number of shoots per explant, shoot length, number of roots per shoot, root length, increase in plant height after successive hardening, number of inflorescence heads per plant, number of floral buds per inflorescence respectively. The analysis of variance (ANOVA) appropriate for the design was carried out to detect the significance of differences among the treatment means and the treatment means were compared using Duncan’s Multiple Range Test (DMRT) at a 5% probability level (Gomez and Gomez,
Would that affect the growth of the plant and the life span? 3. What would happen if the Venus flytrap were to be watered with salt water other than rain water? Hypothesis When peat-free compost is used the plant, Venus flytrap, will grow twice as less as with peat compost when observed over a period of six weeks. Aim To determine the growth and the life span difference between when using peat compost against using peat-free compost in a fixed temperate
So forth did Award Urea after conducting tests with BWD every 1 weeks. How to Apply Fertilizer on Rice plants: Sow evenly on paddy fields, if the system uses tiles. If using Legowo row planting system, of the system is necessary fertilizer only at the place of existing plants or outside legowo. Giving or distribution itself can be done through the legowo. There is also a provision of fertilizer dijimpitkan or placed at intersections within tanman rice.

Pest Management Barn Owl Owl, Tyto alba javanica is used to control rats problem at field such as Rattus argentiventer, Rattus tiomanicus and Rattus diardii. Therefore, barn owl is build from north to south. The reason of build pattern is to prevent sunlight penetration into the barn. This biological control method was done after full percentage identification of rats population at field area.
