Since open-field agriculture will face some severe problems in the near future like availability of land and agricultural productivity, an alternative cultivation system, such as soilless cultivation is needed for the sustainability of supply and demand for healthier and safer food. This study aimed to test the effect of vermicompost application method and dosage on growth, yield, and chlorophyll content of water spinach. This experiment used a factorial randomized block design with controls. The first factor was the vermicompost application method, which consisted of three levels, namely solid vermicompost, the combination of solid and liquid vermicompost, liquid vermicompost. The second factor was the vermicompost dosage, which consisted of five levels: 100, 200, 300, 400, and 500g per polybag, compared with control using inorganic fertilizer. The results showed that the vermicompost application method did not significantly affect plant growth and yield. The dosage of 500g in the three different application methods gave significantly higher plant growth compared to control. The fresh weight of water spinach per plant and per polybag in the dosage of 500g showed the highest yield of 13.95g and 122.17g, respectively. The highest chlorophyll content of water spinach was found in solid vermicompost treatment with an application rate of 500g, namely 30.10 µg/ml (chlorophyll A) and 54.79 µg/ml (chlorophyll B). These results indicate that to produce high-quality water spinach in soilless culture systems, it is recommended to use solid vermicompost with an application rate of 500g per polybag.

Nutrient availability is very significant in supporting plant growth. The low content of organic fertilizers and existing minerals appear as the primary limiting factors for soybean cultivation on acid soils. Therefore, the purpose of this research is to determine the effect of organic fertilizers and Plant Growth Promoting Rhizobacteria (PGPR) on plant growth and yield. A completely randomized block design (CRBD) factorial with three replications was employed, where the first variable involved the chicken and cow composts as well as Tithonia green fertilizer. Meanwhile, the second referred to PGPR at 0, 5, 10 and 15 ml.L-1. The results showed no interaction between the application of organic fertilizers and PGPR on soybean growth as well as the yield. Furthermore, the cow manure treatment of 10 t.ha-1 reportedly increased the total dry weight and sample growth rate by 0.44 and 0.86%, respectively, compared to the chicken manure at similar composition. Also, 10 ml.L-1 of PGPR was known to improve the pod quantity per plant and harvest index by 0.58 and 2.66% harvest index, correspondingly, than without PGPR.

Excessive nitrogen fertilization and improper management can cause a decrease in NUE in the maize cropping system. Most nitrogen fertilizers are applied when the corn is 4-5 weeks after planting. However, recent studies have shown that modern hybrids take up high amounts of nitrogen at the flowering stage. This suggests that a nitrogen fertilization strategy that starts at the beginning of vegetative growth and later in the flowering phase is needed to maximize the yield of hybrid maize in upland. The study was conducted in 2018-2019 in Liban, Jawi, and Toke Kutaye Districts in the West Showa Zone of the Central Highlands of Ethiopia. The research design used a randomized block design with the one-time treatment of fertilizer application consisting of six levels, namely 1/3 at planting + 1/3 at 4-5 weeks after an emergency (WAE) + 1/3 at 70-80 days after planting (DAP ); 1/3 part at planting + 2/3 part at 4-5 WAE; 2/3 share at 4-5 WAE + 1/3 at 70-80 DAP; 1/4 at planting + 1/2 at 4-5 WAE + 1/4 at 70-80 DAP; 1/2 at 4-5 WAE + 1/2 at 70-80 DAP; and full at 4-5 WAE). Nitrogen fertilization on2/3part at 4-5 WAE + 1/3 part at 70-80 DAP significantly affected plant height, cob length, grain yield, and biomass yield, but it did not influence root and stem lodging. When the data were combined over the two years, the treatment of 2/3part N application at 4-5 WAE (knee height) + 1/3 part at 70-80 DAP (before tasseling) resulted in the highest grain yield with a yield advantage of 1,598 kg/ha and gave maximum net benefit over the typically used full application at 4-5 WAE (knee height). This fertilizer management strategy could be advised for the Liban Jawi, Toke Kutaye areas, and other similar agro-ecosystem environments.

Soybean is including a major protein source with a relatively higher consumption rate. Similarly, various efforts have been adopted towards boosting production, including selecting high-yield species and soil fertility improvement using fertilizers. This research aims to increase soybean production by employing the appropriate variety and phosphate fertilizers to improve soil fertility. This experiment was conducted in Takalar, South Sulawesi, between April-July 2019. The split-plot design method was applied with three replications. Consequently, the main plot encompasses the treatment of three varieties, termed Argomulyo, Anjasmoro and Gema, while the subplots relate to phosphate fertilization, comprising three levels, including fertilization with a dose of SP-36 at 50, 100 and 150 kg.ha-1. The results showed that the modifications in variety and phosphorus fertilization significantly influenced soybean production, as Argomulyo obtained the maximum rate of 2.77 t.ha-1, followed by Anjasmoro at 2.45 t.ha-1. Furthermore, phosphate fertilization with a dose of SP-36 at 100-150 kg.ha-1 demonstrated the optimal soybean production as indicated by the maximum productive nodes and pods. Therefore, no interaction was observed between the various species and phosphate fertilization.

The success of durian pollination in nature is very low (<5%) due to high self-incompatibility in durian flowers. Artificial cross-pollination is an alternative method that can be used to increase the successful pollination of durian. So, information on the pollen viability of the durian flower and the time of artificial cross-pollination accurate and effective is required. This research aimed to examine the pollen viability of the durian varieties of Montong and Sitokong varieties at three different times and to determine the success rate of artificial cross-pollination between both varieties at three different times. This research was carried out at the Morpoyan Seed Center and the Genetic and Breeding Laboratory of the Faculty of Agriculture, UIN Suska Riau. Pollen viability testing used the staining method. Artificial cross-pollination between the Montong durian and the Sitokong durian was carried out reciprocally at three different times (11.00–13.00, 15.00–17.00, and 19.00–21.00). The total number of flowers crossed was 300. The results of this study showed that the percentage of pollen viability of Montong durian at 11.00–13.00, 15.00–17.00, and 19.00–21.00 was 94.91, 97.67, and 97.23%, respectively. While the pollen viability of Sitokong durian was 93.33% at 11.00–13.00, 94.45% at 15.00–17.00, and 94.76% at 19.00–21.00. The successful rate of crosses of durian Montong (♀) x Sitokong (♂) at 11.00–13.00, 15.00–17.00, and 19.00–21.00, respectively were 46, 26, and 34%, while the percentage of success of durian Sitokong crosses (♀) x Montong (♂) is 48% at 11.00–13.00, 54% at 15.00–17.00, and 22% at 19.00–21.00. Successful artificial cross-pollination between Montong and Sitokong durian or vice versa was higher at 11.00–13.00 compared to other times. The results of this study can be utilized to formulate the timing of artificial cross-pollination of durian in the future.
