Non-organic agriculture has succeeded in increasing the production of lowland rice, but on the other hand also has a negative impact on the ecosystem of agriculture and the environment, such as the decreasing content of soil organic matter. One effort that can be done, is by adding bio-slurry organic fertilizer to the NPK fertilizer. This study was conducted to determine the effect of the combination of bio-slurry fertilizer and NPK fertilizer on the production of four rice paddy varieties. This research by experiment was conducted in Screen House Agrotechnopark, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Tembalang Semarang campus, taking place from October 2018 to January 2019. The experiment used a randomized completely block design with two factors and three replications. The first factor was a combination of bio-slurry + NPK fertilizer ie without N (P0) fertilizer, NPK 550 kg ha-1 fertilizer (P1), bio-slurry fertilizer 3 tons ha-1 + NPK fertilizer 400 kg ha-1 , 6 tons ha-1 bio-slurry fertilizer + 250 kg ha-1 NPK fertilizer, 9 tons ha-1 bio-slurry fertilizer + 100 kg ha-1 NPK fertilizer and 12 tons bio-slurry fertilizer ha-1. Whereas the second factor was the lowland rice varieties namely Inpari 23, Sultan Unsrat, Sintanur and Gilirang. The results of the variance analysis showed that the combination of bio-slurry + NPK fertilizer and lowland rice varieties had a very significant effect on grain yield per clump, number of filled grains, number of empty grains, total grain count, weight of 1000 grains, rice yield per pot and harvest index. The highest grain yield per clump (85.33 g) was obtained from the treatment of 550 kg ha-1 NPK fertilizer, while the highest grain yield per clump (58.06 g) was obtained from the Gilirang variety (V4), the highest total grain amount (174.58 grains) was obtained from the treatment of NPK 550 kg ha-1 and (212.28 grains) fertilizer produced by varieties Inpari 23. The highest yield per pot of rice (61.83 g) was obtained from the treatment of 550 kg ha-1 NPK fertilizer , while the highest paddy rice varieties which produced rice per pot of (63.22 g) were Inpari 23.
非有机农业在提高低地水稻产量的同时，也对农业生态系统和环境产生了负面影响，如土壤有机质含量下降。一种可行的办法是在氮磷钾肥料中加入生物浆有机肥。本试验旨在研究生物浆肥与氮磷钾肥配施对4个水稻品种生产的影响。实验研究于2018年10月至2019年1月在迪波尼戈罗大学三宝垄校区畜牧与农业学院Screen House Agrotechnopark进行。试验采用双因素、3个重复的完全随机区组设计。第一个因素是生物浆+氮磷钾肥料的组合，即不施氮(P0)肥，NPK 550 kg ha-1肥(P1)，生物浆肥3吨ha-1 + NPK肥400 kg ha-1, 6吨ha-1生物浆肥+ 250 kg ha-1 NPK肥，9吨ha-1生物浆肥+ 100 kg ha-1 NPK肥和12吨ha-1生物浆肥。而第二个因素是低地水稻品种，即Inpari 23, Sultan Unsrat, Sintanur和Gilirang。方差分析结果表明，生物浆+氮磷钾肥与洼地水稻品种配施对籽粒单株产量、灌浆粒数、空粒数、总粒数、千粒重、亩产和收获指数均有极显著影响。氮磷钾550 kg hm -1处理籽粒单产最高(85.33 g)，吉日让(V4)籽粒单产最高(58.06 g)，总粒数最高(174.58粒)的氮磷钾550 kg hm -1 +英百丽23(212.28粒)处理。550 kg hm -1氮磷钾处理的亩产最高，为61.83 g，而亩产最高的水稻品种为英丽23号(63.22 g)。

Eggplant pest attack, does not only decrease quantity of the yields, but also the quality. Because of this, it needs effort to use resistant eggplant againt the pests. The purpose of this research was to evaluate the intensity of pest attack on several types of eggplant and their effect on the yield. The design used in the study was a completely randomized block design (RCBD). The research was consisted of 4 treatments with 3 replications. The treatments were 4 types of eggplant that were purple , white eggplant, green eggplant, and green streak white. Data were analyzedby F Test, if it was significantly different, by then it was continued with DMRT (Duncan’s Multiple Range Test) at the level of 5%. Pest attack intensity of grasshopper (Orthroptera: Acrididae), caterpillars (Lepidoptera: Pyralidae), ladybird Epilachna sp. (Coleoptera: Coccinellidae), leafhopper Amrasca sp. (Hemiptera: Cicadellidae), and Aphis sp. (Hemiptera: Aphididae) on the eggplant types showed there was no significantly difference. The intensity of pest attacks which were not significantly different in all types of eggplant along with the results of analysis of plant height and number of fruits which also showed there was no significantly difference in all type eggplants.

Punung is a village in Pacitan Regency which potentiall for cultivating of cocoa, on the contrary it produces low seeds quality. This condition is caused by unintensive fertilization and low light intensity caused by shading. The effort to increase cocoa seed quality was by light compensation and the use of nitrogen (N) fertilizer. The purpose of this reseach was to determine of optimum N dosage fertilizer for inproving seed quality. The research was arranged in Completely Randomized Block Design with one factor which is the varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization was applicated three times. Fertilization of P (SP36) and K (KCl), 1390 and 1000 gram tree-1 year-1 respectively. The observation variables are soil character, micro climate, leaf anatomi, physical and chemical seed quality. The result showed that N fertilizer influenced positively toward increasing potassium (K) content in leaf tissue on the first and second month, while on the third month no significant influence toward N, P and K content. However there was preference of increased N, P and K content in leaf tissue on each month although in small rise number. In the leaves tissue, there was detected that nitrogen proportion was larger than potassium and phosphorus. N fertilizer increased the physical and chemical seed quality (protein and fat content). Optimum dosage was 870 gram tree-1 year-1, highest weight of 100 seed (146 gram) and seed quality was categorized as grade 1.

Mung beans are one of the common beans comodities consumed after soybeans and peanuts. The national mung beans production was 0.7 tons in average, which is lower than the potential yield. Production of mung bean can be improved by modifying the microclimate by mulching and regulating crop density. The purpose of this research was to improve the yield of mungbean. Research method used was Completely Randomized Design (CRD). The treatments were organic mulching of mahagony leaves, straws, husks, and without mulch (M1, M2, M3, M0) and the crops density 1 and 2 crops (B1 and B2). The results showed interaction between organic mulches and crops density significantly affected the crops’ height and number of productive branches. Interaction of straw mulches and two crops density increased the crops’ height 37,91% than the control and has the most productive branches. Organic mulches significantly affected to flowering period and number of hardseeds. Husk mulches accelerated flowering period and decrease the number of hardseeds. Organic mulch and number of crop’s density treatments has not to improve the yield of mungbean yet. The yield of mungbean can achieved in this research was 1,54 ton ha-1.
