Abstract

Regulators (PGRs) are used to stimulate the development and growth of bulbs in order to produce a large number of bulbs. This study aims to identify the effect of PGRs and boron formulations that can increase the growth and yield of several variety of shallots. This research took place in the cultivation field of Ngringo Village, Jaten District, Karanganyar Regency from April-August 2023. The method used was a Complete Randomized Blok Design (CRBD) consisting of two factors with four replications. The first factor was PGRs and Boron formulation (without and with GA3 200 ppm+BAP 50 ppm+NAA 50 ppm+ IAA 300 ppm + 1500 ppm boron formulation). The second factor was variety (Bima Brebes, Maja Cipanas, Batu Ijo and Tajuk). Data were analyzed by F test with 95% confidence level followed by Duncan’s Multiple Range Test (DMRT) with 95% confidence level. The results showed that the application of PGRs formulations GA3 200 ppm + BAP 50 ppm + NAA 50 ppm +IAA 300 ppm + 1500 ppm boron on shallots of Tajuk varieties was able to increase number of leaves by 5 leaves and able to increase number of bulbs per clump of 3 bulbs compared to without the aplication of PGRs and boron formulations. The Tajuk variety provides the best growth in fresh weight of 16 g higher stalks and in the yield of fresh weight of bulbs per clump 23 g compared to the Batu Ijo variety. Shallots treated with 200 ppm GA3 + BAP 50 ppm + NAA 50 ppm +IAA 300 ppm + 1500 ppm boron have not shown an increase in growth and yield accros various shallot varieties.

Abstract

Soil degradation is a major constraint to agricultural sustainability, particularly in areas characterised by diverse environmental conditions. Halong District, Balangan Regency, South Kalimantan Province, is characterised by heterogeneous land uses, soil types, slope variations, and variable rainfall patterns, which influence soil quality and degradation risks. This research aims to assess the potential for soil degradation concerning environmental diversity and its implications for sustainable integrated agriculture. The study highlights that differences in land use, from shifting cultivation to permanent farming, combined with acidic soils, steep slopes, and uneven rainfall distribution, increase vulnerability to erosion, nutrient depletion, and declining soil fertility. The results show that the Potential Soil Degradation Risk (PSDR) in the low-risk class (PSDR.II) covers 298.22 km2 (45.20%), followed by the intermediate-risk (PSDR.III) covering 335.15 km2 (50.79%), and the high-risk (PSDR.IV) covering 26.48 km2 (4.01%). Land use and slope are determining factors for PSDR, as indicated by ANOVA, DMRT, and correlation test results. Understanding these linkages is essential for designing site-specific land management practices that reduce degradation risks while improving agricultural productivity. The outcomes of this research are expected to provide scientific recommendations for stakeholders in developing sustainable agricultural management strategies, such as soil conservation, organic matter management, and integrated crop-livestock systems, to mitigate degradation risks and support long-term agricultural resilience in Halong District.
