Nutrient Management of Shallot Farming in Sandy Loam Soil in Tegalrejo, Gunungkidul, Indonesia

Abstract

The serious problems of sandy soils for crop development are low water-holding capacity, nutrient retention, and low content of all nutrients. The objective of the study was to increase the nutrient content of sandy soil and evaluate nutrient types that mostly affect the high shallot yield with reasonable economic values. The field experiment was conducted on the upland sandy loam soil. Six treatments consisting of complete nutrients, N-, P-, K-, Mg- and S-omission tests were arranged in a randomly completed block design with four replicates. The observed parameters included soil physicochemical properties, tissue nutrient content, growth, yield, and input-output of shallot cultivation. The results showed that N, P, K, Mg and S application successfully increased shallot bulb, achieving 11.43 t ha−1 on sandy soil. The order of shallot tissue content was K > N > P~Mg > S, where the S, P, N, and Mg are limiting factors, as revealed by significantly lower relative yield (varying from 79 to 88%). The highest weight loss during storage occurred for S-omission treatment (40 to 60%), indicating insufficient S tissue is the most responsible for the quality of shallot. The complete nutrient treatment gave the highest income (7446.09 USD ha−1) with a revenue cost ratio of 2.41 compared to other treatments. The tolerance limit for price reductions that do not cause losses was 58.59%.

The effect of cultivation habits on the growth and yield of several shallot varieties

“…Primary data were obtained through observation and interviews. The parameters observed include plant height, number of leaves, number of bulb splits, the intensity of pests and diseases, number of the bulb, diameter of the bulb, fresh weight of bulb per plant, consumable dry weight of bulb per plant, and tuber weight loss [5,14]. Meanwhile, secondary data is obtained from literature and other supporting libraries.…”

“…Shallots are valuable spices and play a crucial role in the human body for both flavoring dishes and medicinal plants [5,6] . The public widely consumes Shallots as a seasoning for flavoring dishes and is used as processed products such as fried shallots [7].…”

Increasing the Efficiency of Cattle Bone Ash P Fertilization with Nano Technology and Its Effect on the Growth and Yield of Shallots

“…Thus, adding P nutrients in the form of nano cattle bone ash by foliar application is expected to meet plant growth needs and increase photosynthesis results. Sutardi et al (2022) stated that the achievement of high shallot yields was due to the availability of macronutrients such as N, P, K, Mg, and S so that they were sufficiently available for plants. P element has a role in bulb formation and smooth carbohydrate metabolism (Tekeste et al, 2018).…”

Modeling of climate parameters with planting area and pest attacked area on shallots for the development of early warning systems and horticultural cropping schedules

“…Shallot production during planting season in Indonesia requires a holistic and adaptive approach considering the unique climatic conditions. The range of shallot cultivation is quite wide, from lowlands until highlands [14] and shallots are commonly farmed in diverse weather conditions, including warm climates in open fields and cold climates with moderate rainfall [15]. By combining traditional knowledge and modern farming techniques, farmers can maximize yields and contribute to the availability of this strategy commodity for both local consumption and the wider market.…”
