Abstract

Application of GA3 and NPK fertilizers is already known to promote growth of plants. Potential effects of GA3 and NPK on the growth of Phalaenopsis ambilis L. orchid were investigated in the present study. However, increasing application GA3 concentrations of 0, 1, 2, 3, 4, 5 ppm/plant and NPK concentrations of 0, 1, 2, 3, 4 gram/plant. The observation started 30, 45, 60, 75, 90 days after application. This research was use the concentration of GA3 and NPK separately (without combination), each treatment showed a significant effect on the number of leaves, stem diameter, leaf area and leaf area index and had no significant effect to plant height variables. Treatment of GA3 (3 ppm / plant) showed positive results on the variable number of leaves, leaf area and leaf area index. Increasing the concentration of GA3 to 5 ppm / plant did not show any significant difference with the treatment of GA3 concentration of 3 ppm / plant. This shows that plants are needed in small amounts. The dose of fertilizer 1 g / plant showed positive results on the variable number of leaves and stem diameter, while for the leaf area variable and leaf area index required higher NPK fertilizer osis ie 2 g / plant. The increase of NPK fertilizer dosage up to 4 g / plant was not significantly different from treatment 1 and 2 g / plant.Keywords: Phalaenopsis ambilis L., GA3, NPK, Growth

Abstract

Garlic (Allium sativum L.) is one of the crops of economic importance that has increased considerably in recent years in Indonesia. Garlic roots have endophytic bacteria with the potential to promote plant growth, which is support in agriculture. Improving the quality and quantity of garlic can be done through the improvement of cultivation. Intensification of local potential systems techniques is a novel technology using electricity induction to improve physical chemical and biological properties in the soil. The electricity induction applied to the soil would increase ion and cation exchange in the ground. SIPLO is a new technology in agriculture and easy to improve for farmers. The result of combination foliar fertilizer and SIPLO were shown a good impact of the application to the production. Induction of SIPLO for 60 minutes and foliar fertilizer of 150 ml / l gave positive results for garlic production.

Abstract

The pattern of durian planting in the community, in general, uses the agroforestry pattern so that in one area of land there is more than one annual crop cultivated (multiple cropping). However, there is no distribution data map and its production potential. Research on mapping and potential of durian production in Wonosalam district is needed as an effort to provide data-based and to develop durian crop farming. The purpose of this study is to map the distribution of plants and the potential for durian production in the Wonosalam sub-district, Jombang district. The research is descriptive with surveys, observation, and in-depth interview methods. Farmer respondents were taken by "purposive sampling" from 4 hamlets. Each hamlet was taken from 15-20 durian farmer respondents. The mapping of the distribution of durian plants was made using Principle Component Analysis (PCA) using the Past (Palaeontological statistic) version 3.14 open source. The results showed that the distribution of durian trees in Wonosalam village was found in the four hamlets studied, namely Sumber, Wonosalam, Notorejo, and Mangirejo. The highest population of durian trees is in the highest order in Sumber hamlet, followed by Mangirejo, Wonosalam, and the lowest is Notorejo. The most planted varieties are local varieties, Bido, other local seedlings, and Introduction varieties (Montong and Weasel King). Bido variety were found in all four hamlets, but the number of farmers who plant these varieties is a maximum of 5 people. Bido variety as a national superior variety needs to be developed and spread to farmers so that it does not become extinct. The total potential of plant population in Wonosalam village is only 0.75% (2,075 trees) out of 278,369 trees in Jombang district. Keywords: durian, distribution, mountains, conservation

Abstract

The conventional system of rice plantation has been applied in Malang, Indonesia. Standard chemical fertilizer and pesticide application were used in this field. Soil samples in rhizosphere of rice plantation showed the existence of several entomopathogenic fungi including Penicillium sp, Aspergillus sp, Trichoderma sp and some unidentified fungi. The diversity value also demonstrated a medium diversity. We conclude that an application of pesticides and chemical fertilizer according to recommended practices, are not negatively affect the diversity of entomopathogenic fungi. Aspergillus sp and Penicilium sp can cause death against Spodoptera litura.
