Abstract: In current era, modern technologies need to be used in agriculture in india to increase crop productivity because over 70% of the rural people depends upon the agriculture fields. Indian farmers are facing challenges such as crop monitoring, Soil and field analysis , estimation of soil conditions, Fighting infections and pests, irrigation monitoring , need of more human power and money etc., To overcome these agricultural challenges, agricultural drones are used in agriculture. Because of the applications of agricultural drone, it can be used easily where the equipment and labors are difficulty to operate in agricultural fields. To yield better crop quality and preventing fields from any sort of damage , agricultural drones are needed. Agricultural drones have a number of advantages over the more traditional agricultural methods. And moreover data processing applications are becoming less expensive and easier to use due to applications of agricultural drones. In this paper brief discussion about classification and importance of drones , application of agricultural drones, future use of agricultural drones etc., are discussed and finally concluded about the need of using modern technologies in agriculture fields . Keywords: Drones, agricultural drones, crop monitoring, crop spraying, pipeline inspection.

Subsurface drainage technology may offer a useful option in improving crop productivity by preventing water-logging in poor drainage paddy fields. The present study compared two paddy fields with and without sheet-pipe type subsurface drainage on land and water productivities in Indonesia. Sheet-pipe typed is perforated plastic sheets with a hole diameter of 2 mm and made from high-density polyethylene. It is commonly installed 30–50 cm below the soil surface and placed horizontally by a machine called a mole drainer, and then the sheets will automatically be a capillary pipe. Two fields were prepared, i.e., the sheet-pipe typed field (SP field) and the non-sheet-pipe typed field (NSP field) with three rice varieties (Situ Bagendit, Inpari 6 Jete, and Inpari 43 Agritan). In both fields, weather parameters and water depth were measured by the automatic weather stations, soil moisture sensors and water level sensors. During one season, the SP field drained approximately 45% more water compared to the NSP field. Thus, it caused increasing in soil aeration and producing a more significant grain yield, particularly for Inpari 43 Agritan. The SP field produced a 5.77 ton/ha grain yield, while the NSP field was 5.09 ton/ha. By producing more grain yield, the SP field was more effective in water use as represented by higher water productivity by 20%. The results indicated that the sheet-pipe type system developed better soil aeration that provides better soil conditions for rice.

Nitrogen is important for crop productivity and usually added in form of urea into the soil which negatively affects the environment. It is important to utilize nitrogen fixing bacteria for improving the nitrogen content of soil in India. Here, we have isolated nitrogen fixing-bacteria Pseudomonas mendocina S10 from rhizospheric soil and studied its nitrogenase activity along with its survival under sterile soil conditions. Enterobacterial Repetitive Intergenic Consensus (ERIC) PCR and Real-time quantitative PCR were employed to investigate the population and nifH transcripts level respectively in presence of ammonium and moisture additives. Strain S10 was capable of growth and expressing nifH transcripts in the presence of 2.5 mM ammonium and 20 percent water availability. Population of isolated strain and it’s nifH mRNA was found at low levels when exposed to 5 mM ammonium for 60 days of incubation period. However, viable bacterial count and nifH transcript levels remained low in the presence of 1.25 mM ammonium and zero percent water content. These findings indicate that isolated strain could tolerate ammonium up to 5 mM for 60 days and can maintained their cell viability in low moisture conditions. Results revealed the advantage of using gene expression to evaluate the physiological state of microorganism’s population in soil.

Indonesia is a country that has vast agriculture and has a majority source of income as farmer. The agriculture area still cannot be optimized considering that still a lot of dry agriculture land and have not got good irrigation system, several problems that cause are still a lot of dry agriculture which higher position of irrigation system available and there are limited land so that if irrigation system built or DAM then operational coast outweigh of impact on the land, another problem occurs is limited ability of community for built independent and modern irrigation system so that assistance is needed and technology that can be utilized as resource for built independent and modern irrigation system. One of potential resource in Indonesia is energy of sun which can be converted to electric power, this is energy very much in Indonesia, so that can be using as energy to pump water from springs to be distributed to dry agriculture land. To be able to reduce human power and monitoring this paper using Ant Colony Optimization as computation system.  This algorithm used to optimized water distribution evenly on dry agriculture land which is adapted to the soil conditions.

Rapid Urbanization

Increasing pressure on farming systems due to rapid urbanization and population growth has severely affected soil health and fertility. The need to meet the growing food demands has also led to unsustainable farming practices with the intensive application of chemical fertilizers and pesticides, resulting in significant greenhouse gas emissions. Biochar, a multifunctional carbon material, is being actively explored globally for simultaneously addressing the concerns related to improving soil fertility and mitigating climate change. Reviews on biochar, however, mainly confined to lab-scale studies analyze biochar production and its characteristics, its effects on soil fertility, and carbon sequestration. The present review addresses this gap by focusing on biochar field trials to enhance the current understanding of its actual impact on the field, w.r.t. agriculture and climate change. The review presents an overview of the effects of biochar application as observed in field studies on soil health (soil’s physical, chemical, and biological properties), crop productivity, and its potential role in carbon sequestration. General trends from this review indicate that biochar application provides higher benefits in soil properties and crop yield in degraded tropical soils vis-a-vis the temperate regions. The results also reveal diverse observations in soil health properties and crop yields with biochar amendment as different studies consider different crops, biochar feedstocks, and local climatic and soil conditions. Furthermore, it has been observed that the effects of biochar application in lab-scale studies with controlled environments are not always distinctly witnessed in corresponding field-based studies and the effects are not always synchronous across different regions. Hence, there is a need for more data, especially from well-designed long-term field trials, to converge and validate the results on the effectiveness of biochar on diverse soil types and agro-climatic zones to improve crop productivity and mitigate climate change.

Modern technologies of cultivation of crops directly depend on climatic parameters: temperature, amount of precipitation and their distribution by months. Crop productivity can be controlled by studying and understanding the influence of the climatic potential of Western Siberia. This paper is devoted to its features. Analysis of the influence of abiotic factors on the yield of spring barley for the period 2014-2019 showed that: the sum of effective temperatures of 1500°C, necessary for the growth and development of plants, accumulates annually; the harvest is formed by atmospheric precipitation for five months (May-September), which is 60% of the average annual norm with fluctuations from year to year from 12.1 to 38.0% (303.6-373.7 mm); the hydrothermal coefficient for May-July has an average effect on the yield of the Abalak, Acha, Vorsinsky 2 varieties (the coefficient of variation of the yield is 11.9, 14.9 and 16.3%, respectively) and significant effect on the crops of the Chelyabinsky 99 variety (the coefficient of variation is 25.7%). The Abalak and Chelyabinsky 99 varieties turned out to be more responsive to changes in growing conditions, as evidenced by the values of the regression coefficient (bi) (1.04 and 1.48) exceeding unity. The Acha and Vorsinsky 2 varieties are characterized by a weak response to improved growing conditions.
