“…Chemical fertilization is a quick method of providing plants with their required nutrients, however, due to its adverse effects on the environment, it cannot be considered as the sole suitable method of fertilization. Accordingly, biological fertilization (use of soil microbes) has been tested as the alternative method of fertilization, and it has been proved to be effective (Berg 2009;Miransari 2011a, b;Miransari and Mackenzie 2012). N and P are the two most important nutrients for plant growth and production.…”

Integrated nutrient management with bio and chemical fertilizers can improve rice (Oryza sativa L.) productivity, bio-fortification, soil health and fertility. Accordingly, this study was planned to evaluate the combined effects of biological fertilizers including arbuscular mycorrhizal (AM) fungi (Glomus mosseae) and free-living nitrogen-fixing bacteria (Herbaspirillum seropedicae), as well as chemical fertilizers on the yield and nutrient contents of wetland rice under field conditions. Seedlings were inoculated with AM fungi and the bacteria in the nursery and were then transplanted to the field. The experiment was carried out as a split factorial design with three replicates. Treatments included three rates of nitrogen (N1, N2 and N3) and phosphorous (P1, P2 and P3) fertilizers (100, 75 and 50% of the optimum level) in the main plots and mycorrhizal and bacterial treatments in the sub plots. The total of urea (g) used per plot was equal to N1=200, N2=150 and N3=100 at three different growth stages (seeding, tillering and heading) and the total of P (g) per plot used once at seeding using triple super phosphate including P1=16, P2=13 and P3=10. Plant growth and yield as well as the concentration of nitrogen (N), phosphorous (P), potassium (K), iron (Fe) and zinc (Zn) were measured in the soil, straw and grains. N-fertilizer and biological fertilizers had significant effects on root, shoot and grain yield of rice, however, P-fertilizer just significantly affected root and shoot dry weight. Interestingly, analyses of variance indicated that biological fertilizer significantly affected all the experimental treatments except straw N. AM fungi, N1 and P1 resulted in the highest rate of rice growth and yield. The interactions of chemical and biological fertilizer resulted in significant effects on grain Zn, Fe, P, and N as well as soil Fe, K and N. The highest rate of grain nutrient uptake was resulted by the combined use of biological fertilizer and the medium level of chemical fertilization. Interestingly, with decreasing the rate of chemical N fertilization, rice nutrient use efficiency increased indicating how biological fertilization can be efficient in providing plants with its essential nutrients such as N. However, the highest rate of soil and straw nutrient concentration was related to the combined use of biological fertilizer and the highest rate of chemical fertilization. We conclude that biological fertilizer, (mycorrhizal fungi and H. seropedicae) can significantly improve wetland rice growth and yield (resulting in the decreased rate of chemical fertilization), especially if combined with appropriate rate of chemical fertilization, by enhancing nutrient uptake (fortification) and root growth.

“…Depth of soil sampling is the first issue to be addressed. For soil sampling for nitrogen measurement Miransari & Mackenzie [16] suggested a depth between 30 cm and 100 cm. Due to the limited payload weight of the AgriRover, it is important to keep the drill weight to a minimum, and deeper penetration will lead to longer and heavier sampling mechanisms.…”

This paper presents an investigation of a novel development of a multifunctional mobile platform for agriculture applications. This is achieved through a reinvention process of a mechatronic design by spinning off space robotic technologies in terrestrial applications in the AgriRover project. The AgriRover prototype is the first of its kind in exploiting and applying space robotic technologies in precision farming. To optimize energy consumption of the mobile platform, a new dynamic total cost of transport algorithm is proposed and validated. An autonomous navigation system has been developed to enable the AgriRover to operate safely in unstructured farming environments. An object recognition algorithm specific to agriculture-has been investigated and implemented. A novel soil sample collecting mechanism has been designed and prototyped for on-board and in-situ soil quality measurement. The design of the whole system has benefited from the use of a mechatronic design process known as the Tiv model through which a planetary exploration rover is reinvented into the AgriRover for agricultural applications. The Agri-Rover system has gone through three sets of field trials in the UK and some of these results are reported.

“…As one of the major food crops in the world, rice feeds more than half of the world's population [24]. With the increasing world population, global climate change, the abuse of pesticides and fertilizers causing environmental pollution, hampering rice productivity, and many other challenges, the human living environment is encountering unprecedented challenges, and there is a surge in demand for healthy foods [25][26][27][28][29]. To realize the sustainable development of agriculture and maintain the ecological balance, it is crucial to lessen the excessive use of chemical fertilizers and pesticides and ensure grain output.…”

In a long-term evolution, fungal endophytes have formed a mutually beneficial relationship with host plants. Therefore, what roles do fungal endophytes play in the growth and development of rice, one of the major food crops in the world, and agricultural production? This mini-review aims to highlight the diversity, identification, colonization, function, and mechanism of action of endophytic fungi isolated from rice tissues through a literature review; comprehensively expound the interaction mechanism between rice fungal endophytes and their hosts in stimulating the growth of rice plants and alleviating biological and abiotic stresses on plants; and contribute new ideas for rice production and a sustainable rice industry. Additionally, rice fungal endophytes, as a new resource, have broad prospects in the development of biopesticides, biocontrol agents, and new medicine.
