the Influence of Nitrogen Nutrition Population Density on the Yield and Yield Components of Grain Sorghum at Fifty Centimeter Row Spacing
No full textTwo sorghum varieties, Darso and Feterita, were subjected to three nitrogen rates and three population densities. The experiment was conducted during the dry season (1967) and during the wet season (1968) at the Central Experiment Station, U. P. College of Agriculture.
Heading for Feterita was earlier than Darso during the dry season but later during the wet season. While Darso was not affected by season, Feterita prolonged the vegetative phase which would account for taller plants during the wet season. As nitrogen increased from 50 to 100 and 150 kilograms per hectare, heading was hastened.
Grain yield for Darso was higher than Feterita during the dry season. Nitrogen treatments, 100 and 150 kilograms, gave significantly higher yield than the 50-kilograms rate. Grain yield was also increased during the dry season as plant population increased from 100,000 to 150,000 and 200,000 plants per hectare
Kesiapan Belajar Siswa Dan Interaksi Belajar Mengajar Terhadap Prestasi Belajar
Get PDFOne of the most important parts to improve the ability to read drawings in learning process is students' learning readiness and teaching-learning interaction on a subject of reading technical drawings, which are often overlooked by school. This study aims to investigate the influence of students' learning readiness and teaching-learning interaction on achievement in the subject of reading technical drawings. The study shows that there is a correlation between students' learning readiness and their academic achievement, which is 0,45; the correlation between teaching-learning interactions exists in the level of 0,67; there is a correlation between students' learning readiness and teaching-learning interactions in the level of 0,34; and there is a correlation of students' learning readiness and teaching-learning interaction on academic achievement, which is 0,71. The coefficient for the variable of students' readiness and teaching-learning interaction is significant in the level of significance α = 0.05. Thus, it can be concluded that the students' learning readiness and teaching-learning interactions between teachers and students provide a meaningful/significant impact on the academic achievement in reading technical drawings subjec

Heading for Feterita was earlier than Darso during the dry season but later during the wet season. While Darsp was not affected by season. Feterita prolonged its vegetative phase which would account for taller plants during the wet season. As nitrogen increased from 50 to 100 and 150 kilogrmas per hectare, heading was hastened.
Grain yield for Darso was higher than Feterita during the dry season. Nitrogen treatments, 1000 and 150 kilograms, gave significantly higher yield than 50-kilogram nitrogen rate.

The Diversity of Insect in Paddy Field in Karawang, West Java with Different Pest Management Techniques
Get PDFThe practice of rice crop cultivation will affect the trophic structure and the diversity of insects that are formed. One of the common cultivation practices carried out by farmers was the control of pests by using pesticides. This study aimed to find out which pest management strategies that are effective in maintaining environmental health and understanding how natural enemies were affected by the application of synthetic pesticides. The first treatment was paddy field with integrated pest management (IPM), the second treatment was conventional rice field with a technique of chemical pest management (C-T), while the third treatment was mixed pest management (M-T). Insect sampling was conducted using sweep net, pitfall trap, and direct observation for 10 weeks after planting. Overall, it was found 100 morphospecies, 9 Orders, 56 families, with a total abundance of 6242 individuals per planting season. Based on functional roles it was found 39% as herbivores, 30% as predators, and 14% as parasitoids, 1% pollinators, and 13% decomposers. High insect diversity and abundance were found in the plots using low synthetic pesticides. The C-T control plot had a lower relative abundance of herbivorous insects, parasitoid insects, predators, and decomposers than the other control plots. H\u27 and D index in the Integrated Pest Management (IPM) and Mixed Pest Management (M-T) plots did not show significant differences but differed significantly from the Chemical Control plot (C-T). Therefore, controlling the herbivore insects could apply the pest management based on IPM strategies.

Fluctuation of Insect Population on Rice Field in Pangkalan Sub-district Karawang Regency: Indicator for Environmental Health
Get PDFPangkalan Sub-district is a forest edge area in Karawang that is rich in flora and fauna that has not been much identified. Because of its unique location that is bordered by primary forest, agricultural ecosystems in the area will not be separated from the influence of the surrounding forest. So, it is necessary to know more about the diversity and abundance of insects in the wetland rice ecosystems.The research was conducted in Pangkalan sub-district, Karawang regency. The size of each plot was 5 x 5 m (25 m2) and each treatment was repeated five times. Treatments carried out with integrated pest management (IPM), chemical pest management techniques (P-K), and Mixed Pest Management (P-C). Insect retrieval technique using sweep net method, yellow pan trap, and direct observation. The abundance of arthropod species found in 12 Orders consist of: Thysanoptera Order (2.4%), Orthoptera (0.5%), Odonata (1.4%), Mantodea (0%), Lepidoptera (8.7%), Hymenoptera (2.4%), Hemiptera (61.8%), Diptera (2.4%), Derma ptera (3.6%), Coleoptera (8.3%), Architaenioglossa (0.5%), and Aranea (8.0%). Based on the species richness, it was found that the orders of Diptera (25 species), Coleoptera (19 species), and Hymenoptera (18 species) showed higher numbers than other orders. The H 'diversity index in this study ranged from 1.99 to 2.45, the D index ranged from 0.73 to 0.88, and the E index ranged from 0.5 to 0.7. Overall the P-K plots showed a lower population abundance compared to IPM and P-C plots. Intense and scheduled spraying of insecticides on P-K plots causes a lower population abundance, which makes the diversity become low.

No full textOne of the limiting factors for sweet corn plant growth is nutrients. The state of nutrients in the soil will determine the yield of sweet corn. To achieve optimum results sweet corn plants require adequate nutrient input. Nutrients are one of the important factors that affect plant growth and development. Fertilization as nutrient fulfillment can be done through the application of a combination of micro organism local (Mol) fertilizer banana hump and NPK compound fertilizer. Provision of micro organisms local and NPK compound fertilizers on sweet corn plants is useful for accelerating the destruction of organic matter, can also serve as additional nutrients and nutrients needed by plants, so as to increase growth and yield of sweet corn plants as expected. The research method used is an experimental method using a single factor randomized block design (RBD). The number of treatments used in this study were 10 treatments which were repeated 3 times. So there are 30 experimental units. The treatments were as follows: A. 300 kg/ha NPK, B. 10 l/ha Mol + 300 kg/ha NPK, C. 20 l/ha Mol + 300 kg/ha NPK, D. 30 l/ha Mol + 300 kg/ha NPK, E. 10 l/ha Mol + 250 kg/ha NPK, F. 20 l/ha Mol + 250 kg/ha NPK, G. 30 l/ha Mol + 250 kg/ha NPK, H. 10 l/ha Mol + 200 kg/ha NPK, I. 20 l/ha Mol + 200 kg/ha NPK, J. 30 l/ha Mol + 200 kg/ha NPK, K. No fertilizer (control). The results showed that the combination of micro organisms local of banana weevil and NPK fertilizer had a significant effect on the growth components. Treatment G with 30 l/ha MOL + 250 kg/ha NPK gave the highest yield of growth components
