Six tomato genotypes were grown in the field under full sun at 50% reduced light intensity using shading net to evaluate growth, fruit set, and fruit cracking incident. The experiment was conducted during the rainy season in December 2016 to March 2017 in Cikarawang Experimental Station, Bogor, Indonesia. The genotypes tested were sensitive (“Tora” and F7005001-4-1-12-5), tolerant (F7003008-1-12-10-3 and F7003008-1-12-16-2), and shade-loving (SSH-3 and “Apel Belgia”). The results showed 50% shading delayed flowering and harvesting time in all genotypes. Genotype and shading treatments had an independent effect on fruit set. Shaded plants had lower flower abortion and resulted in a higher number of fruits per harvest, except in “Apel Belgia” and “Tora” genotypes. Fruit cracking incidents were low under shading implying the use of shading can increase tomato quality. However, it needs further investigation through using natural shading, e.g., intercropping system before this finding is applied in farmers’ field.

Pemupukan N pada padi hibrida menjadi krusial mengingat varietas padi hibrida sangat responsif, sehingga harus diketahui dosis yang tepat untuk menghasilkan produksi yang tinggi. Penelitian ini bertujuan untuk mengkaji pengaruh dosis N terhadap serapan N, efisiensi penggunaan N, dan hasil padi hibrida. Penelitian menggunakan Rancangan Acak Kelompok yang diulang tiga kali. Faktor pertama adalah varietas padi hibrida yang terdiri dari Varietas Mapan P05, Varietas SL-8 SHS Sterling, dan Varietas Intani 602. Faktor kedua adalah dosis pemupukan N yang terdiri dari kontrol tanpa pemupukan N, dosis N 100 kg ha-1, dan dosis N 200 kg ha-1. Terdapat respon yang beragam antar varietas padi hibrida terhadap taraf pemupukan N, Serapan N, efisiensi penggunaan N tertinggi yang dihasilkan oleh varietas Intani 602 masing-masing sebesar 138,57 %, dan 36,13%. Serapan N tanaman padi tertinggi dicapai pada dosis N 100 kg ha-1, dan efisiensi penggunaan N tertinggi pada dosis N 200 kg ha-1. Hasil gabah tertinggi dicapai pada varietas Mapan P05 sebesar 7,42 t ha-1, dan dosis pemupukan N 100 kg ha-1 memberikan hasil tertinggi sebesar 7,47 t ha-1. Implikasi dari penelitian ini bahwa dosis nitrogen 100 kg ha-1 dapat menjadi acuan sebagai dosis pemupukan N varietas padi hibrida di Indonesia. Hybrid rice is responsive to nitrogen, so it’s necessary to find the optimum dose to optimize the production. The aim of this research was to examine the effect of nitrogen on N uptake, N use efficiency, and yield of hybrid rice. This study used a randomized block design with three replications. The first factor consisted of the Mapan P05 variety, the SL-8 SHS Sterling variety, and Intani 602 variety. The second factor was Nitrogen dosage consisted of control, 100 kg ha-1, and 200 kg ha-1. There were various responses among hybrid rice varieties to the level of fertilization. The highest N uptake and N use efficiency was achieved in the Intani 602 variety at 138.57% and 36.13%, respectively. The highest N uptake was achieved at 100 kg ha-1 of N, and the highest N use efficiency was at 200 kg ha-1. The highest yield was achieved in the Mapan P05 variety (7.42 t ha-1), and the dose of N at 100 kg ha-1 gave the highest yield (7.47 t ha-1). The implication of this research is that the nitrogen dose of 100 kg ha-1 can be used as a reference for hybrid rice varieties fertilizer in Indonesia.

Research on rice plant breeding to get superior black rice varieties with tender rice texture can be carried out by crossing Black Rice and Mentik Wangi variety. The rice lines derived from a crossing of these two varieties have recently reached the F6 line. The texture of rice is distinguished by the amylose content. The lower of the rice amylose, the more tender of the rice texture, and vice versa. This study aimed to find out the profile of amylose content and the grains morphology of the lines that will be developed as waxy pigmented rice. Analysis of amylose content was carried out using iodine-colorimetry methods. The quantification of amylose was measured based on the regression of the standard amylose curve. The results showed that all the F6 lines had the potential to be developed as waxy pigmented rice. Based on the Kruskall Wallis test, there was a variance in the amylose profile average of the eight genotypes. In terms of grains morphology, the line 482-17-7 and 482-17-18 had a combination colour between the two parents. In addition, there was a significant difference in grains size between the genotypes and the grain size of all lines were classified in the medium size. F6 lines resulted from the crossing between Black Rice and Mentik Wangi are recommended to be used as superior varieties of waxy pigmented rice.

Abstract. PP Al Jamil is an Islamic boarding school in Banyumas regency, Central Java, with 126 pupils. This number of occupants would certainly produce a significant amount of organic household waste. The technology transfer introduced to the school as a community service was a method to turn organic waste into organic fertilizers for growing vegetables. So far, vegetables consumed in PP Al Jamil have been obtained from the nearest markets. A pre-trial survey conducted on the pupils in March 2020 showed that the majority (90%) understood the difference between organic and inorganic wastes. Furthermore, some students had sorted wastes into those two categories (61.22%), generated organic fertilizers from household waste (53.06%), and grown vegetables (65.30%). Based on this information, the technology transferred to the pupils increased the knowledge and skills on producing organic fertilizers and cultivating vegetables. The procedures comprised lectures, discussions, practices, and counseling on the above subjects, including pest control, fertilizing schedule, and plant care. A post-trial survey conducted in September 2020 indicated that the pupils' understanding of waste types increased by 10%, while their experience in vegetable farming increased by 26.37%. Furthermore, this community service activity reduced the school's daily expenditure on vegetables by 50%. --- Abstrak.

Introduction: Plants that grow and develop in a shaded environment are difficult to produce optimally. Therefore, the use of plant species that are able to produce optimally in a shaded environment is very important to be used as an agroforestry area. The research purposes was to observe morpho-physiological characters that can be used as characters to determine chilli plants that can produced in low light intensity area. Methods: A field experiment was conducted at farmer field in Pekuncen, Banyumas, Indonesia from May to October 2020. The research was arranged in randomized complete block design (RCBD) with three replications. The first plot was shading intensity (0% (control) and 50%) and the second plot consisted of nine chilli varieties, V1 (Segana), V2 (Lada Hijau), V3 (Bara), V4 (Catas),V5 (Kerinci), V6 (Raya), V7 (Genie), V8 (Sonar), and V9 (Rajo). Results: The results of this research showed that shade affected on leaves number and leaves area, but not affected on plant height and stem diameter. Shading net was affected on chlorophyll a and b, but not affected on chlorophyll content. Decreasing of total chlorophyll on 50% shade net occurring in shade sensitive varieties was significantly different than shade-tolerant varieties. Tolerant varieties based on the observation criteria were Bara (V3), Genie (V7), and Sonar (V8). Conclusion: Leaf area and leaf pigment character can be used as a reference for determining the resistance of varieties to low light.
