It also saves a large amount of irrigation water without having a negative impact on yield. Considering the relationship between water consumption and the amount of energy consumed, the evaluation of water productivity (WP) and energy productivity (EP) seems essential to develop a suitable method for efficient use of water for agriculture in the arid regions with limited water resources. Therefore, in this study, it was attempted to investigate WP and EP, some nutritional traits and stress indices for silage maize and silage sorghum in a loamy sandy soil using a drip tape irrigation system. For this purpose, a field experiment was performed using a randomized complete block split-plot design with three replications under three irrigation levels of I1: 100% (conventional), I2: 80%, and I3: 60% of the crop evapotranspiration (ETc), and four cultivars of sorghum and maize were planted as the main and split plots. The irrigation scheduling was done using a reference crop evapotranspiration (ETo) calculator (Penman–Monteith equation) and AquaCrop simulation model. The results showed that the amount of irrigation water had a significant effect on fodder and dry yield, WP and EP (<i>p</i> &lt; 0.01). The values of fresh and dry yields and WP for silage maize were 61.23 tons/ha, 18.91 tons/ha and 10.73 kg/m<sup>3</sup>, respectively. However, for silage sorghum, with relatively lower water requirements, these values were much higher (103.84 tons/ha, 30.00 tons/ha and 19.82 kg/m<sup>3</sup>, respectively). The maximum WP and EP for sorghum and maize were obtained in I3 and I1 treatments, respectively. It was also found that the nutritional traits, including dry matter (DM) and crude protein (CP), were affected by crop type (sorghum and maize) and deficit irrigation levels. Hence, the maximum DM (31.72%) and CP (9.607%) were observed for Speedfeed sorghum cultivar under I1 irrigation level, the maximum ash (9.86) was reported for Speedfeed sorghum cultivar under I3 irrigation level, the maximum neutral detergent fiber (NDF) (74.47%) was obtained for Maxima maize cultivar under I1 irrigation level, and the maximum acid detergent fiber (ADF) (39.183%) was achieved for Pegah sorghum cultivar under I1 irrigation level. According to the results, it was concluded that it would be wise to replace sorghum with maize in order to achieve higher WP in arid regions.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135193866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recognizing the significance of alternate wetting and drying technology in sustainable agriculture, this study aims to promote the adoption of this technology among both Good Agricultural Practices (GAP) and non-GAP farmers in Suburban, Bangkok, Thailand. Data were collected through a structured questionnaire, which gathered information on farmers' cost and return values, as well as their adoption opinions. The collected data were then analyzed using cost and return analysis, as well as stochastic frontier analysis. The results indicate that non-GAP farmers face significantly higher total costs due to increased fixed costs compared to GAP farmers. While there were no significant differences in yield between the two groups, GAP farmers achieved significantly higher total income and net profit due to lower total costs and higher selling prices. Furthermore, the analysis suggests that both groups of rice farmers have the potential to improve their efficiency levels, with non-GAP farmers showing a higher potential for improvement. In terms of adoption opinion, both farmer groups recognize the advantages of wet and dry farming technology over traditional flooded rice farming. This study highlights that the adoption levels of both GAP and non-GAP farmers can be significantly improved through the implementation of best management practices. Overall, the findings emphasize the importance of trustworthy information dissemination to encourage the adoption of wet and dry farming technology, as it enhances farmers' trust in the received information and their engagement with the technology.

This calibrated UAV performed automated optical sensing and intelligent planning options apart from data collection which was subjected to 3D spectral analysis and derive functions of Leaf Area Index Curve Fit Models, Logistic and S-Curve functions. The schematics embedded in the UAV were re-designed and iterated to obtain ordinal data that was classified into hyperspectral information by way of a <i>k</i>-means algorithm to function as a text stream cluster based on adaptive feature selection. The study endorsed that Object Based Image Analysis with algorithms of AI asymptotically can derive yields that was previously thought of as impossible. The study also reinforces that conjoining UAV technology and transportation science can address challenges across the commercial spectrum in an analytical and portable pattern by looping the routing and scheduling path (fixed interval repetition) of UAV’s which is of paramount importance and unique to this current study.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47902259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
