In this study the plant growth-promoting bacteria were analysed for their growth-stimulating effects on two wheat cultivars. The investigations were carried out in pot experiments using calcareous soil. The results showed that bacterial strains Pseudomonas spp. NUU1 and P. fluorescens NUU2 were able to colonize the rhizosphere of both wheat cultivars. Their plant growth-stimulating abilities were affected by wheat cultivars. The bacterial strains Pseudomonas sp. NUU1 and P. fluorescens NUU2 significantly stimulated the shoot and root length and dry weight of wheat cv. Turon, whereas cv. Residence was less affected by bacterial inoculation. The results of our study suggest that inoculation of wheat with Pseudomonas strains can improve plant growth in calcareous soil and it depends upon wheat cultivars. Prior to a selection of good bacterial inoculants, it is recommended to select cultivars that benefit from association with these bacteria.

The search for plant growth-promoting rhizobacteria is an ongoing need for the development of new bioinoculants for use in various crops, including sugarcane. Bacterial strains with various plant growth-promoting properties can contribute to sustainable agricultural production. The present study aimed to isolate, characterize and select sugarcane rhizobacteria from six different varieties through principal components analysis. This study selected 167 bacterial strains with the ability to fix nitrogen, produce indolacetic acid, exhibit cellulolytic activity, and solubilize phosphate and potassium were isolated. Of these 167 bacterial strains, seven were selected by principal component analysis and identified as belonging to the genera Staphylococcus, Enterobacter, Bacillus and Achromobacter. Bacillus thuringiensis IP21 presented higher potential for nitrogen fixation and CaPO4 and AlPO4 solubilization and a lower potential for K solubilization in sugarcane. Enterobacter asburiae IP24 was efficient in indolacetic acid production and CaPO4 and FePO4 solubilization and inefficient for Araxá apatite solubilization.

The community service aims to empower the pineapple farmers (Ananas comosus L.) in Ngancar and Plosoklaten Districts, Kediri Regency, by improving cultivation technology to produce higher quality fresh fruit and diversifying post-harvest products to add various marketable products. Farmers need for pineapple seeds that have not been met and improper plant cultivation technology were some of problems faced by farmers in this area. In addition, superior varieties developed are still limited, hence choices in improving quality are limited. Farmers limited knowledge on the post-harvest technology in pineapple cultivation has caused the farmers have no other choice but to market their products only in the form of fresh fruit. Part of the plant which is prioritized for production was only the fruit, there has not been any innovation in utilizing other plant parts such as pineapple leaves as raw material for pineapple fiber industry. In this community service, counseling has been successfully conducted on the selection of pineapple seedlings and superior varieties, improvement of pineapple plant maintenance and Plant Growth-Promoting Rhizobacteria (PGPR). Implementation of community service started with socialization and counseling on the selection of pineapple seedlings and superior varieties, improvement of pineapple plant maintenance and PGPR. In addition, practice and assistance were carried out in the characterization and selection of superior varieties of pineapple seedlings. The result obtained is that the partner community is able to apply pineapple plant cultivation technology in an integrated manner.   Keywords: Pineapple, extension, seeds, superior varieties.   ABSTRAK Tujuan pengabdian masyarakat adalah pemberdayaan kelompok tani Langgeng Mulyo nanas (Ananas comosus L.) di Kecamatan Ngancar dan Plosoklaten, Kabupaten Kediri dengan cara perbaikan teknologi budidaya untuk menghasilkan buah segar yang lebih berkualitas dan diversifikasi produk pasca panen untuk menambah berbagai produk yang bisa dipasarkan. Permasalahan pada Kelompok Tani di Kecamatan Ngancar dan Kecamatan Plosoklaten, Kabupaten Kediri, antara lain adalah kebutuhan bibit nanas yang belum dapat dipenuhi dan teknologi budidaya tanaman nanas yang kurang tepat. Varietas unggul yang dikembangkan masih terbatas sehingga pilihan dalam perbaikan kualitas menjadi terbatas. Keterbatasan pengetahuan tentang teknologi pasca panen pada pelaku budidaya nanas menyebabkan pelaku budidaya tidak mempunyai pilihan lain selain memasarkan produk hanya dalam bentuk buah segar. Bagian tanaman yang diutamakan produksinya hanya pada bagian buah, belum terdapat inovasi memanfaatkan bagian tanaman yang lain seperti daun nanas sebagai bahan baku industri serat nanas. Pada pengabdian ini telah berhasil dilakukan penyuluhan mengenai seleksi bibit nanas dan varietas unggul, perbaikan pemeliharaan tanaman nanas dan Plant Growth Promoting Rhizobacter (PGPR). Pelaksanaan pengabdian masyarakat dilakukan diawali dengan sosialisasi dan penyuluhan tentang seleksi bibit nanas dan varietas unggul, perbaikan pemeliharaan tanaman nanas dan PGPR. Selain itu dilakukan praktek dan pendampingan dalam karakterisasi dan seleksi bibit nanas varietas unggul. Hasil yang diperoleh adalah masyarakat mitra mampu menerapkan teknologi budidaya tanaman nanas secara terpadu.   Kata kunci: Nanas, penyuluhan, bibit, varietas unggul.

The response of sugarcane (Saccharum spp.) families to the inoculation with plant growth-promoting bacteria (PGPB) may show positive or negative interaction values depending on the plant genotype, allowing the selection of responsive genotypes to the association. Based on these precepts, this study aimed to evaluate the response of 27 sugarcane families treated with two PGPB-based inoculants in two sugarcane cycles: plant-cane and first ratoon. Four months after germination, 27 families from crosses between clones of sugarcane were: (T0) not inoculated; (T1) inoculated with Triazo, which consists of a mixture of the strains Abv5, Abv6, and Abv7 of Azospirillum brasilense; and (T2) inoculated with an inoculant called Mix, which contains five strains of PGPB (Gluconacetobacter diazotrophicus Pal5, Azospirillum amazonense CBAmC, Burkholderia tropica Ppe8, Herbaspirillum rubrisubalbicans HCc103, and Herbaspirillum seropedicae HRC54). The productivity traits evaluated were the number of stalks, average height, stalk diameter, and Brix. The correlation values between the two cycles were 0.87 for the number of stalks, 0.70 for average height, 0.48 for stalk diameter, and 0.63 for Brix. Differences were observed between treatments for average height, stalk diameter, and Brix. Differences were also observed between families for all the studied traits. Brix was the only parameter that presented a significant interaction between family and inoculant. Different responses were observed between cycles for some families, showing that other factors can also influence the association.
