Response and productivity of Garlic (Allium Sativum L.) by different levels of potassium fertilizer in farm soils

Abstract

Background: Garlic (Allium sativum L.) has been used as a medicine throughout ancient and modern history; it has been taken to prevent and treat a wide range of conditions and diseases. In Bangladesh, the demand for garlic increases day by day, but on the other hand, due to a shortage of land, production of garlic is not up to the mark. 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 2007 to March 2008 to examine the effect of potassium (K) on the growth, yield, nutrient content, and its uptake by garlic. Results: In this study, six levels of K viz. 0, 100, 125, 150, 175, 200, 250 kg ha −1 were used as treatments. All the parameters, i.e., plant height, number of leaves plant −1 , fresh and dry weights of leaves (g plant −1), fresh and dry weights of bulb (g plant −1), bulb diameter, and number of cloves bulb −1 significantly varied due to different doses of K application. The maximum total yield and size of garlic bulb were obtained with potassium application at 200 kg ha −1. Potassium at 200 kg ha −1 produced the highest fresh and dry weights of bulbs and leaves, diameter, moisture content, number of cloves, and yield as compared to the other treatments. The uptake of nutrients like N, P, K, S, Ca, Mg, B, and Na significantly varied due to the application of different doses of K. The highest contents and nutrient uptake of N, P, K, S, Ca, Mg, B, and Na were found with potassium application at 200 kg ha −1. Conclusions: The overall results suggested that the yield of garlic increased with increasing potassium fertilizer, where K application at 200 kg ha − 1 is suitable for obtaining maximum yield.

The Effects of Using Sulfur and Organic Bedding on the Content of Macro- and Micronutrients and Biologically Active Substances in Winter Garlic Bulbs

“…In this study, more P in cloves was determined in cultivation with S (0.42% DM on average) without mineral fertilization than without S (0.38% DM on average). Jiku et al [73] determined the P content in garlic cloves at the level of 0.15% DM in cultivation without K fertilization (K0) and 0.35% in cultivation with K 200 kg ha −1 . The above-cited authors also showed that potassium increases the N content in garlic bulbs.…”

Salinity Stress Alleviation by Foliar Bio-Stimulant, Proline and Potassium Nutrition Promotes Growth and Yield Quality of Garlic Plant

“…Scientists reported that the uptake of different nutrients by garlic plant varied significantly due to the different application levels of K. Potassium alone induced maximum uptake of all the elements studied (N, P, K, S, Ca, Mg, B, and Na) at K at 200 kg•ha −1 and the lowest in control K0 treatment [29]. It was found that these essential and beneficial nutrients could protect crop plants against both abiotic and biotic stresses by enhancing the plant resistance power and regulating the mineral nutritional status [32].…”

“…Proline accumulation is a common physiological response in many plants in response to a wide range of biotic and abiotic stresses [33]. It is obvious from data presented in Table 4 that Jiku et al [29] reported that the maximum total yield and size of garlic bulb were obtained with potassium application at 200 kg [31], K is responsible not only for higher production but also for the improved quality of the harvest. Thus, K…”

“…Open Journal of Soil Science timing are critical for generating a yield, high quality response, and good storage ability of garlic. As crop yields increase, the amount of K required also increases, along with all other nutrients[29]…”

Influence of Planting Dates and Some Nk-Rates on Productivity and Storability of Garlic

“…Furthermore, contents of N, P and K in leaf and bulbs of garlic and volatile oils in bulbs were much increased by increasing N-level (Naruka, 2002 andShokr, 2005). Likewise, several researchers reported that garlic plants growth and yield were improved by application of potassium (El Sayed and El Morsy, 2012;Arisha et al, 2017 andJiku et al, 2020). Furthermore, Maupua and Rathoipe (2007), Shiferaw et al (2015) and Khan et al (2016) found that the garlic plant growth, yield and its quality were increased with increasing NP and/or NK rates.…”
