Abstract

Aphis glycine is one of the soybean pests that can develop rapidly and cause yield loss. Neem is a plant known as botanical incesticide. This study tested the toxicity of neem cake against A. glycine and its effect on increasing tannin content in the soybean plant. The effect of neem cake extract to the mortality of A. glycine was tested by spray method and root dipping method. The application was carried out on four-week-old soybean plants with 10 individual of adult A. glycine as test insects.  Observations were carried out every day for 8 DAT (day after treatmen) by counting the population of A. glycine. The testing of tannin levels and azadirachtin content  is done by applying neem cake extract using root dipping method. The treatment is divided into two groups, which are infested plants and non-invested plants by A. glycine. The leaf of soybean (fourth day after application) was taken as samples for tannin and azadirachtin analysis. The results showed that the extract of neem cake at the spray method caused the death of A. glycine up to 97% at a concentration 2.5%. The root dipping method could make mortality of nymphs (new born) 100% at concentrations of 0.1% and 0.125% at 8 DAT , but cannot make mortality to adult of A. glycine. The tannin content in soybean plants (with A. glycine and without A. glycine invested) was increased after 0.125% neem cake application. Azdirachtin uptake was not detected at concentrations of 0.125% and 0.250% at 5 DAT. Neem cake extract can suppress A. glycine population in soybean plants and increase of tannin content in plants.

Abstract

Golden snail is one of the important pests that attack paddy crops. The structure of golden snail is divided into 3 based on the size of the shell diameter, namely juveniles (0.5-1 cm), preadults (1-2.5 cm), and adults (2.5-4 cm). The paddy cultivation system can affect the golden snail population. The purpose of this study was to determine the density, distribution and population structure of the golden snail (Pomacea canaliculata L.) with case studies in Cicalengka (conventional field) and Ciparay (organic field), District of Bandung, from October 2020-January 2021. This research used survey method with sampling technique in purposive sampling.  At each location divided into 5 fields with sized 10x5 m which were divided into 7 quadrant plots. Sampling was carried out at the age of paddy crops 14,21,28, and 35 days after planting. The observerd parameters were density, distribution pattern using the Index of Morisita (Id) and population structure of P. canaliculata. The results showed that the density of P. canaliculata in organic field was higher than in conventional field. The average population structure of pre-adult golden snails in organic and conventional rice fields was significantly different at 14-35 days after planting (DAP) and adult golden snails at 14, 28, and 35 DAP. Distribution pattern of P. canaliculata in organic and conventional were grouped.

Abstract

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords:  Chili, Chromolaena odorata, compost  fertilizer, tanglefoot

Abstract

Burung bondol jawa (Lonchura leucogastroides) merupakan salah satu hama pada tanaman padi ketika memasuki fase generatif. Petani seringkali menjaga sawah selama sehari penuh untuk mengendalikan hama burung. Cara tersebut kurang efektif karena banyak waktu petani yang terbuang hanya untuk mengendalikan burung. Penelitian ini bertujuan untuk mengetahui tingkat kematangan padi yang disukai bondol jawa dan mengetahui kelimpahan kunjungan tertinggi burung bondol jawa di sawah. Penelitian dilakukan pada bulan Maret hingga bulan Mei 2020 bertempat di lahan sawah milik petani di Desa Cileles, Jatinangor dan Laboratorium Vertebrata, Fakultas Pertanian, Universitas Padjadjaran. Metode uji kelimpahan kunjungan tertinggi dilakukan dengan menghitung jumlah burung yang berkunjung pada lahan penelitian. Sementara itu, metode uji preferensi pada bondol jawa dilakukan dengan membandingkan bagaimana cara makan bondol jawa ketika diberi pakan padi yang matang susu dan padi yang sudah matang penuh. Hasil penelitian menunjukkan bahwa bondol jawa menyerang sepanjang pengamatan, yaitu 11 MST-14 MST. Tingkat kematangan padi yang disukai bondol jawa adalah saat matang susu. Kelimpahan bondol jawa mengunjungi sawah adalah saat sore hari, yaitu mulai dari jam 14.00 hingga jam 17.00. Hal ini menunjukkan bahwa masa tersebut dapat digunakan petani untuk mengendalikan hama burung di sawah.

Abstract

The aquatic ecosystems in rice fields has macroorganisms such as aquatic arthropods which have an important function in the food web. The siam weed and neem cake can be utilized as organic fertilizer to support the productivity and biodiversity of the paddy field, This research aims to understand application of organic fertilizer on diversity of aquatic arthropods and black rice performance in the field ecosystem. The experiment was carried out in paddy field at Jatinangor from January to June 2020. The method used was an experimental method with a Randomized Complete Block Design consisted of five treatments (neem cake, siam weed compost, cow manure, synthetic fertilizer and control) with six replications. The result showed that the abundances of aquatic arthropods have tendency to be higher in neem cake at 1104 individuals and siam weed compost treatments at 905 individuals compared to the cow manure, NPK and control. Furthermore, the diversity index of the aquatic arthropods in all treatments were categorized as moderate with details as follow neem cake (H’=1,726), cow manure (H’=1,450); synthetic fertilizer (H’=1,458); siam weed compost (H’=1,450) and control (H’=1,502). In addition, the evenness index (E) of aquatic arthropods was higher in neem cake treatment (E=0,623) compared to other treatments. Whereas, the dominance index (C) and richness index (R) in all treatments showed no dominant species and it classified as low category. The results also showed that the siam weed compost were not significantly different with all treaments except NPK (synthetic fertilizer) in plant hight, tiller number and SPAD value.
