“…Ruidisch et al (2013) evaluating nitrate leaching in horticultural areas observed that the split of nitrogen fertilization can reduce nitrate leaching by up to 59%, generating a higher nitrate content available to plants. In addition, split can increase fertilizer efficiency due to the provision of higher doses in phenological stages that the crop needs most, preventing N from participating in biochemical processes in the soil and becoming unavailable to plants (Viana et al, 2020).…”

Evaluating the effects of crop successions in no-tillage system (NTS) is essential for the correct recommendation of agronomic practices, such as top-dressing nitrogen fertilization. The aim was to evaluate the effect of the crop succession and the splitting of top-dressing N fertilization on the agronomic performance and economic viability of common bean crop. The experiment was conducted in southeastern Brazil for two agricultural seasons in an area under NTS, using a split-plot in randomized complete block design. The plots represented three cropping successions (maize in sole crop, maize intercropped with Urochloa ruziziensis and U. ruziziensis in sole crop) and the subplots composed of ten combinations of splitting of top-dressing N, at the stages V3, V4 and R5 of the common bean crop. In relation to the single application of the N dose of 90 kg ha−1, the common bean had higher response as a function of the N splitting schemes adopted, regardless of the previous cropping succession. The cropping successions evaluated did not interfere with the seed yield of common bean as subsequent crop, even at the beginning of the establishment of NTS. To obtain higher seed yield and economic viability, the N dose of 90 kg ha−1 indicated for the crop must be split and applied among the phenological stages V3, V4 and R5.

Potatoes are one of the horticultural commodities with high economic value and have the opportunity to fill the domestic and export markets. However, potato productivity in Central Java tends to decline due to suboptimal fertilization technology. This study aims to assess crop growth, potato production, and the economic feasibility of potato farming. The experiment was carried out in Sumberejo Village, Batur District, Banjarnegara Regency, in September-December 2021 with a pilot demonstration plot covering an area of 0.4 ha by applying dibbling and spreading fertilization. Data on plant growth and production were analyzed using average values and t-tests‒; input-output data were analyzed financially to calculate economic feasibility. The results showed that the dibbling method had an insignificant effect on the vegetative and generative plant growth, but potato production by dibbling was about 3 kg ha-1 compared to production by dispersing. The dibbling method gave a higher profit memberikan nilai keuntungan lebih tinggi with B/C = 0.81 compared to the dispersed method with B/C = 0.68. The change in fertilization from spread to dibble gave high benefits with an indication of MBCR = 8.11. If there is a decrease in production and prices, then fertilization by dibbling has a higher tolerance limit (44.87%) to the losses caused than dibbling fertilization, which has a tolerance limit of 40.49%. Keywords: fertilization methods, economic feasibility, potato, profits, production

Potato is one of the horticultural crops with high economic value and potential as an export commodity. The productivity of potatoes in Central Java tends to decrease, and it is suspected that the use of production inputs is not optimal. This study aims to evaluate the performance of the use of production inputs, the factors that influence potato production, and the optimization of the use of production inputs in potato farming in the Dieng Plateau. The research was conducted from October to December 2021 in Sumberejo Village, Batur Subdistrict, Banjarnegara District, which has an altitude of + 1700 meters above sea level. This research used a survey method on 30 potato farmers. The data obtained were analyzed descriptively, and analyzed the factors that influence production using multiple linear regression, followed by an optimization test on the use of production inputs. The results showed that the use of production inputs among farmers still varied and had not followed the results of soil analysis. Seed, manure, and labor are production inputs that have a significant positive effect on potato production. To get maximum production, farmers need to add seeds, NPK fertilizer, and manure according to recommendations, while the use of labor needs to be reduced to achieve optimal yields. Keywords: highlands, inputs, increased production, potato, production
