Considering the aforementioned information, the aim was to evaluate the occurrence of lateral shoot growth and productivity characteristics in garlic plants, cv. Chonan, subject to herbicide chemical stress. The chemical stress caused by herbicides paraquat, ammonium gluphosinate and glyphosate in underdoses of 25, 40 and 36 i. Garlic Allium sativum is cultivated in most regions of Brazil, both by large and small producers. In this sense, several factors have been related to the lateral shoot growth in garlic, such as photoperiod Wu et al. In vernalized noble group garlic cultivars, the lateral shoot growth has been the cause of greatest concern, given they are more sensitive to this anomaly.

However, to solve the problem, a pot culture experiment was conducted at the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period of November to March to examine the effect of potassium K on the growth, yield, nutrient content, and its uptake by garlic.
In this study, six levels of K viz. All the parameters, i. Garlic is a member of the family Liliaceae. It is the second most widely used spices crop of Allium after onion Purseglove One million hectares of garlic produce about 10 million metric tons of garlic globally each year, according to the United Nations Food and Agriculture Organization FAO The average yield of garlic in Bangladesh is very low as compared to other countries of the world FAO In Bangladesh, the demand for garlic increases day by day because of gradual increase in utilization in different ways and means.
It is not possible to increase the area of crop due to the limitation of land. So, the way to solve this problem is by increasing the yield per hectare and this can be done in many ways.
The most important is by using the proper doses of fertilizers. The production of garlic in Bangladesh is still in the hands of marginal farmers. Its production technology has not yet been standardized. Moreover, necessary in-depth knowledge and information regarding the use of potassium fertilizer in garlic production under Bangladesh conditions are scanty.
The judicious application of fertilizer may enhance bulb yield significantly. Potassium K is a vital nutrient for increasing garlic yields. Proper application rates and timing are critical for generating a yield or quality response.
As crop yield increase, the amount of K required also increases, along with all other nutrients Mendez et al. Total bulb yield was increased with increasing level of K application Sing and Verma ; Sharma et al. Potassium helps in the root development and increasing the efficiency of leaf in the manufacture of sugar and starch. It is essential for the translocation of sugars. It exerts a balancing role on the effect on both nitrogen and phosphorus. Consequently, it is especially important in multi-nutrient fertilizer application Brady Thus this research aimed to study the effect of K addition on growth, bulb yield, and quality of garlic.
Considering the above facts, the present investigation was undertaken with the following objectives to observe the effect of different levels of K fertilizer on the growth, yield, and quality of garlic and to determine the impact of different levels of K on the nutrient content and their uptake by garlic.
The pot experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh from November to March Kharif season April to September and Rabi season October to March were considered and details of climatic condition viz.
Bulbs were collected from Kushtia district of Bangladesh. The cloves of uniform size were selected for planting. The average weight and diameter of the cloves were 1. The initial surface soil samples were collected 15 cm depth and the collected soil samples were air-dried and sieved with 2 mm sieve. This experiment was conducted in a completely randomized design CRD and total of seven treatments were used in three replicates.
Collected soil samples were mixed with potassium K using seven different pre-treatments as described below, K0: 0 kg K only soil , K kg K, K kg K, K kg K, K kg k, K kg K, K kg K per hectare respectively. Each pot contained a total amount of 7 kg of soil.
The dimension of the used plastic pots was 35 cm of height with a top diameter of 30 cm. All kinds of fertilizers were applied to soils before the planting of cloves. Only nitrogen was applied in three splits. First split was applied before planting the cloves and the second split was applied at 30 DAS as well as third split at 60 DAS. Both time fertilizers were applied as broadcast and incorporated into the soil followed by weeding.
Seven cloves were planted in each pot. The depth of planting was around 2. Frequency of irrigation depends upon the moisture status of the soil. Irrigation was provided in each pot uniformly after the application of nitrogen fertilizer at 90 days after planting DAP. After the complete emergence of the crop, Rovral at 50 g mixed with 10 l of water and applied every 15 days later to prevent the attack of diseases.
Extra care was taken so that no bulb was injured during lifting. Five plants were randomly selected from each pot. The following parameters were considered such as plant height, and a number of green leaves per plant was measured at 30, 45, 60, 75, 90, DAP. The Fresh weight of leaves of were weighted. The fresh weight of bulb was taken from five sample bulb and calculated the average value of individual bulb. Bulb diameter was measured with slide calipers from the five sample plants and calculated the average value.
The number of cloves of sample bulbs were counted and average number of cloves was calculated. Moisture content was calculated according to the following formula:. Where W 1 is the initial weight of sample and W 2 is the final weight of sample. Soil pH was measured by pH meter. The soil to water suspension ratio was 1 to 2. Organic carbon was determined by the wet oxidation method as described by Black and the organic matter content was calculated by multiplying the percent organic carbon with the Van Bemmelen factor of 1.
Total nitrogen in initial soil was determined by micro-kjeldahl method. Digestion by titration followed by the Page et al. The percentage of nitrogen in the soil was calculated by the following formula:. Where V is the volume of 0.
Phosphorus was estimated colorimetrically by the stannous chloride method as described by Jackson The content of potassium in the plant samples was determined separately with the help of flame emission spectrophotometer using appropriate filters as described as Ghosh et al. The concentration of sulfur in the extract was estimated turbidimetrically with the help of a spectrophotometer as described as Wolf Calcium content in plant samples was determined by the complexometric method of titration using Na2EDTA as a complexing agent at pH 12 where calcon was used as an indicator Page et al.
Boron concentration of the extract was determined colorimetrically as described by Page et al. The content of Na in plant extract was determined by the use of flame photometer and the intensity of light emitted by sodium at nm Jackson After chemical analyses of plant samples, the nutrient contents were calculated and from the value of nutrient contents, nutrient uptakes were also calculated by the following formula:.
The data were analyzed statistically by F test Gomez and Gomez The mean differences of the treatments were adjusted by least significant difference LSD test. The physical and chemical properties of the initial soil have been presented in Table 1. The result of K on yield and yield contributing characters of garlic have been presented in Tables 2 and 4. The highest plant height was At DAP, the maximum number of leaves were 7.
