The estimation of crop phenological distribution is of great importance for controlling time of thinning flowers. In order to improve the efficiency of flower thinning in modern orchard, a detection method of apple flower phenological distribution based on YOLO-CG network model is proposed to detect, which aims at improving incomprehensive and low-efficient manual traditional detection method of apple flower phenological distribution. First of all, the YOLO-CG network model is to integrate the CA mechanism into the YOLOv5 network, which could obtain more shallow features to improve network performance; Secondly, in order to improve the training speed to reduce the calculation amount of the network model, the Ghost-Bottleneck module is proposed to replace the Bottleneck module; Finally, the CIOU is used as the bounding box regression loss function to improve the stability of the target box regression. The model is fine-tuned and trained with manually-marked apple flower images in 4 phenological stages. The proposed method was compared with the detection models of YOLOv3, YOLO v4, YOLO v5 and Faster R-CNN, and the detection performance of apple flower under different shooting conditions are discussed, which proves the effectiveness of this method. Experimental results show that the mAP value of apple flower detection at different stages was 94.90%, an increase of 1.98%, 7.1%, 5.42% and 2.53% respectively compared with Faster R-CNN, YOLO v3, YOLO v4 and YOLO v5.
Root rot is a serious threat to the sesame crop, causing a significant yield loss in Odisha, India. Ten isolates were recovered from different geographical locations in Odisha, India, to understand the relationship among phenotypic characteristics, virulence, and genetic base of the pathogen Macrophomina phaseolina. Genetic diversity analysis using four ISSR primers generated twenty-seven bands with 71.9% polymorphism. The PIC value ranged from 0.59 to 0.663, with a maximum PIC value in ISSR9. UPGMA grouped isolates into three distinct clusters with 60 % genetic similarity. The ordination of isolates in the dendrogram and PCA analysis showed a consistent relationship of geographic origin with the genetic base of the pathogen. A similar grouping pattern was observed based on phenotypic traits and virulence of isolates. All isolates exhibited a significant variation in phenotype (colony colour, colony type, growth rate, aerial mycelium microsclerotia size, shape, colour, and abundance) and virulence (against cultivar VRI- 1). In addition, a negative correlation was observed between the sizes of microsclerotia with virulence. The findings confirm a considerable variation among the isolates and a strong relationship between phenotypic characteristics, virulence, and the genetic base of the pathogen. Knowledge of these characteristics may help to understand the population structure of the pathogen.
Internet of Things (IoT) has been a serious influence in agriculture since its application to the sector. This paper provides an in depth review of the employment of good technologies in agriculture and elaborates the progressive technologies for good agriculture together with, web of Things, cloud computing, machine learning, and computer science. The application in smart agriculture in crop production and post-harvesting is mentioned. The impact of climate change on agriculture is additionally thought-about. This paper contributes to information by iterating the challenges of good technology to agriculture whereas lightness the problems known from existing framework of smart agriculture. The authors determine several gaps in existing analysis affecting the application of IoT in smart agriculture, and counsel any analysis to boost the current food production globally, to supply higher food management and property measures across the world.
This study has accessed the economic impact of Sub-Surface Drainage (SSD) technology on sugarcane production. The 'with' and 'without' approach was adopted for the collection and analysis of data. 60 sample farmers ‘with SSD’ and 60 sample farmers ‘without SSD’ consisting of total 120 farmers were selected from three tahsils of Sangli district of Maharashtra. The average per hectare establishment cost of SSD system was observed to be Rs. 1,38,183. The per quintal cost of production for adsali sugarcane for with and without SSD farms was Rs. 219 and 279 respectively. The gross return of adsali sugarcane was observed to be 40.77 per cent more on ‘with SSD’ farms as compare to the ‘without SSD’ farms of adsali sugarcane. The per quintal cost reduction for adsali sugarcane observed to be 27.43 per cent on ‘with SSD’ farms over the ‘without SSD’ farms. The per farm gross income accrued from cultivation of adsali sugarcane was Rs. 414675.25 and Rs. 245619.15 on farms with and without SSD, respectively showed an increase of 40.77 per cent in gross returns due to the adoption of SSD technology. While, the farm business income, family labour income, net income were also higher on farms with SSD over the farms without SSD with the tune of 67.98, 86.65and 104.44 per cent, respectively.
Seed pelleting is the process in which inert materials are added to seed with an objective to improve seed placement, germination and crop stand and to reduce seed rate and to impart protection against various biotic and abiotic stresses specially in case of pulses as few of them have very small seeds which are difficult to handle otherwise. In present scenario pulses are proving to be an essential immunity booster as they are rich source of proteins and other essential nutrients. In Indian prospects the major constraints in pulse production are their low production and productivity. Thus, seed pelleting has vast potential to overcome these issues because of above stated advantages.
