ABSTRAK Euchema cottonii mengandung unsur mikro dan makro nutrien, serta zat pengatur tumbuh tanaman seperti auksin, giberelin, sitokinin, dan etilen sehingga sangat berpotensi sebagai pupuk organik penyubur tanaman. Penambahan buah nanas berfungsi sebagai sumber C, P, dan K pada ekstrak pupuk rumput laut cair. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan bioaktivator PGPR (Plant Growth Promoting Rhizobacteria)dan buah nanas terhadap kandungan C-organik, nitrogen, fosfor, kalium, pH, suhu, bakteri patogen, dan organoleptik warna. Material yang digunakan dalam penelitian ini adalah E. cottonii, PGPR, dan buah nanas.. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan yaitu perlakuan kontrol (A), penambahan PGPR dan  buah nanas 40% (B), penambahan PGPR dan buah nanas 50% (C), dan penambahan PGPR dan  buah nanas 60% (C). Parameter yang diukur adalah C-organik, nitrogen, fosfor, kalium, pH, suhu, bakteri pathogen, dan oraganoleptik warna. Data parametrik dianalisa dengan uji ANOVA. Hasil penelitian menunjukkan bahwa penambahan buah nanas yang berbeda memberikan pengaruh nyata terhadap kadar C-organik, fosfor, dan kalium (p<0,05), sedangkan nilai nitrogen tidak berbeda nyata. Perlakuan penambahan nanas 50% akan meningkatkan kandungan nitrogen dua kali lebih besar dari pada kontrol. Perlakuan terbaik yaitu pada penambahan PGPR dan nanas 60% dengan kandungan C, P, K berturut-turut adalah 7,02%, 3,44%, dan 3,41%. Kata kunci: Euchema cottonii, Pupuk Oganik Cair, PGPR,  Nanas ABSTRACT Euchema cottoniicontains elements ofmicroandmacronutrients, andplantgrowth regulatorssuch asauxin, gibberellin, cytokinin, andethyleneso ithasgreat potentialas anorganicfertilizer forfertilisingcrops.

Micronutrient Fertilizer

At present in agricultural techniques engaged the optimal nutrient supply is very imperative factor for elevated crop yield and all essential plant macro and micronutrients. Micronutrients play vital role in photosynthesis. For balanced crop nutrition micronutrient support is essential. Micronutrient fertilizer required in small quantities by plants and occupy vital role in physiology of plant kingdom. Proven fact is decisive plant functions are over involved if enough micronutrients are engaged. In this paper the author developed a new N-P-K fertilizer fortified with tri -micronutrient matrix and its application for optimal Plant growth. The author developed and analyzed hundred percent water soluble active fertilizer(15-15-15) with three important micronutrients (-3.4 0.5%Zn, 0.5%Fe, 0.5% Mg). Pot experiments were conducted with and without proposed fertilizer on Solanum lycopersicum(tomato) seeds. The proposed enhanced efficiency fertilizer with tri micronutrient matrix showed better plant growth as compared to normal untreated fertilizer in low nutrient soil field.

Soil salinity is the main obstacle to worldwide sustainable productivity and food security. Zinc sulfate (Zn) and paclobutrazol (PBZ) as a cost-effective agent, has multiple biochemical functions in plant productivity. Meanwhile, their synergistic effects on inducing salt tolerance are indecisive and not often reported. A pot experiment was done for evaluating the defensive function of Zn (100 mg/L) or PBZ (200 mg/L) on salt (0, 50, 100 mM NaCl) affected pea plant growth, photosynthetic pigment, ions, antioxidant capacity, and yield. Salinity stress significantly reduces all growth and yield attributes of pea plants relative to nonsalinized treatment. This reduction was accompanied by a decline in chlorophyll, nitrogen, phosphorus, and potassium (K+), the ratio between K+ and sodium (Na+), as well as reduced glutathione (GSH) and glutathione reductase (GR). Alternatively, salinity increased Na+, carotenoid (CAR), proline (PRO), ascorbic acid (AsA), superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) over nonsalinized treatment. Foliar spraying with Zn and PBZ under normal condition increased plant growth, nitrogen, phosphorus, potassium, K+/Na+ ratio, CAR, PRO, AsA, GSH, APX, GR, and yield and its quality, meanwhile decreased Na+ over nonsprayed plants. Application of Zn and PBZ counteracted the harmful effects of salinity on pea plants, by upregulating the antioxidant system, ion homeostasis, and improving chlorophyll biosynthesis that induced plant growth and yield components. In conclusion, Zn plus PBZ application at 30 and 45 days from sowing offset the injuries of salinity on pea plant growth and yield by upregulating the antioxidant capacity and increasing photosynthetic pigments.

Soil microbiota are vital for successful revegetation, as they play a critical role in nutrient cycles, soil functions, and plant growth and health. A rehabilitation scenario of the abandoned Kettara mine (Morocco) includes covering acidic tailings with alkaline phosphate mine wastes to limit water infiltration and hence acid mine drainage. Revegetation of phosphate wastes is the final step to this rehabilitation plan. However, revegetation is hard on this type of waste in semi-arid areas and only a few plants managed to grow naturally after 5 years on the store-and-release cover. As we know that belowground biodiversity is a key component for aboveground functioning, we sought to know if any structural problem in phosphate waste communities could explain the almost absence of plants. To test this hypothesis, bacterial and archaeal communities present in these wastes were assessed by 16S rRNA metabarcoding. Exploration of taxonomic composition revealed a quite diversified community assigned to 19 Bacterial and two Archaeal phyla, similar to other studies, that do not appear to raise any particular issues of structural problems. The dominant sequences belonged to Proteobacteria, Bacteroidetes, Actinobacteria, and Gemmatimonadetes and to the genera Massilia, Sphingomonas, and Adhaeribacter. LEfSe analysis identified 19 key genera, and metagenomic functional prediction revealed a broader phylogenetic range of taxa than expected, with all identified genera possessing at least one plant growth-promoting trait. Around 47% of the sequences were also related to genera possessing strains that facilitate plant development under biotic and environmental stress conditions, such as drought and heat.

After the nitrogen phosphorus is the second most important plant nutrient to necessary for plant development and growth. The use of excess phosphate fertilizers potentially causes surface and ground water pollutions and soil fertility depletation and accumulation of phosphate in soil which is unavailable for plant. Biofertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, solubilized insoluble soil phosphates and produces plant growth substances in the soil. There have been a number of reports on plant growth promotion by microorganisms that have the ability to solubilize inorganic and organic P from soil. There is a dynamic and complex relationship among the different forms of P involving soil, plant and microorganisms. Microorganisms can enhance the capacity of plants to acquire P from soil through various mechanisms. They are able to solubilize unavailable form of unsolubilized phosphate in available form. Purpose of this review is to focuses on the understanding of the mechanism of phosphate solubilisation their role of PSMs(phosphate solubilizing microorganisms) in crop production as biofertilizers.
