Abstract

Lombok Island, Indonesia, possesses approximately 893,758 ha of dryland with significant potential for developing drought-tolerant crops such as sweet sorghum (Sorghum bicolor L.) to strengthen food security in semi-arid regions. This study evaluated the agronomic adaptation of three sweet sorghum varieties, namely Bioguma 3, Soper 9, and Numbu, under two contrasting dryland agroecosystems: clay-textured Vertisol in East Lombok (pH 6.8, organic C 2.2%, CEC 64.6 me/100 g) and sandy loam Entisol in North Lombok (pH 6.3, organic C 1.0%, CEC 15.9 me/100 g). The experiment employed a randomized complete block design with four replications, observing stem biomass, leaf biomass, and grain yield at 75, 90, and 105 DAS. Results demonstrated that soil physical and chemical properties strongly influenced varietal performance. The Vertisol soil, characterized by high cation exchange capacity and moisture retention, significantly enhanced vegetative growth, with Bioguma 3 producing the highest stem biomass (75.00 tons/ha) and leaf biomass (8.18 tons/ha). In contrast, the Entisol soil generated lower biomass yields (41.64 tons/ha stems and 5.55 tons/ha leaves) but supported more stable grain production across varieties. Soper 9 recorded the highest grain yield, reaching 6.09 tons/ha on Vertisol and 4.70 tons/ha on Entisol. These findings highlight the importance of integrating appropriate varietal selection with soil management strategies to improve dryland agricultural productivity and promote sustainable food security.

Abstract

A single and long-term use of inorganic fertilizers harms soil quality. Therefore, it is highly recommended that inorganic fertilizers be combined with other fertilizers. This study explores the synergistic effect of inorganic, organic, and biofertilizers on maize rhizosphere properties and production. Biochar (BC) and compost (OF) were applied as organic sources, a consortium of phosphate solubilizing bacteria (PSB) was applied as phosphate biofertilizers, while urea and NPK-PONSKA fertilizers (IF) were used as inorganic fertilizers. A greenhouse experiment was designed as a completely randomized arrangement involving six treatments in triplicate, namely control (only IF), a combination of IF+BC, IF+PSB, IF+BC+PSB, IF+PSB+OF, and IF+BC+OF+PSB. The best changes in soil microbial and chemical properties, maize root dry weight, and production were observed in the IF+BC+OF+PSB combination, followed by IF+OF+PSB, IF+BC+PSB and (IF+BC; IF+PSB) and control treatment, respectively. A fertilizer combination involving the addition of BC (IF+BC, IF+BC+PSB, IF+BC+OF +PSB) significantly increased soil organic C content and soil pH compared to without biochar (IF+PSB and IF+OF+PSB). A higher root dry weight also results in higher maize production. Maize production Increased in the 4, 3, and 2 combinations compared to production in the control by 43.11%, 31.32-36.55%, and 18.57%-21.34%, respectively. In conclusion, the synergy of biochar, compost, and PSB, when integrated with fertilizer, can improve soil quality and the sustainability of maize production. This study will be useful in developing sustainable nutrient management programs to increase crop productivity with high efficiency in using inorganic fertilizers.Barbarslot adalah salah satu situs resmi slot deposit 5000, 5rb dan depo 5k terbaru dengan beragam permainan terbaik tahun 2025.
