    EVALUATION OF THE EFFECTS OF DEFICIT IRRIGATION LEVELS UNDER DRIP IRRIGATION WITH MULCHING ON TOMATO YIELD AND WATER PRODUCTIVITY.
    (BUSITEMA UNIVERSITY, 2026) ABESIGA, Dennis
    Tomato production in Busia District, eastern Uganda, is increasingly constrained by seasonal water scarcity and inefficient irrigation practices. This study evaluated the effects of three deficit irrigation levels 100% (I₁), 75% (I₂), and 50% (I₃) of crop evapotranspiration (ETc) combined with two mulching treatments (mulched and non-mulched) on tomato (Money Maker) growth, yield, soil moisture dynamics, and water productivity under drip irrigation. The experiment was conducted at Busitema University Research Field, Busia District, during the dry season from December 2025 to March 2026, using a Randomized Complete Block Design (RCBD) with a 3×2 factorial arrangement replicated three times. Results showed that both irrigation level and mulching had highly significant effects (P<0.001) on all measured parameters. The highest marketable yield of 44.17 t/ha was recorded under I₁+Mulch (full irrigation with mulching), while the lowest yield of 20.39 t/ha was recorded under I₃+No Mulch. Mulching provided a mean yield advantage of 4.41 t/ha (+14.2%) across all irrigation levels. Critically, the I₂+Mulch treatment (75% ETc with mulching) achieved a yield of 39.14 t/ha statistically equivalent to full irrigation without mulch (39.61 t/ha) while using 25% less irrigation water. Soil moisture content was maintained above the permanent wilting point (0.10 g/g) in all treatments throughout the season, validating the 50% management allowable deficit (MAD) scheduling approach. The I₂+Mulch treatment recorded the highest irrigation water use efficiency (IWUE) of 17.70 kg/m³, surpassing the full irrigation treatment (16.26 kg/m³), and reduced seasonal irrigation demand by 504 m³/ha compared to full irrigation. The I₂+Mulch treatment was identified as the optimal deficit irrigation strategy, offering the best balance between yield, water productivity, and irrigation efficiency for smallholder tomato production under drip irrigation in Busia District. These findings provide practical, evidence-based guidelines for farmers, extension workers, and policymakers on sustainable irrigation water management for tomato production in sub-humid eastern Uganda.

    President Museveni's simplicity: Why all water is not safe for irrigation
    (New Vision, 2017-01-06) Kanyarusoke, Kant Ateenyi
    Are you inventing a rain-making machine? A close relative and childhood playmate, now in Kampala- Grace Kiiza- teased me during my protracted doctor of engineering research in solar energy. She had learnt I was working on some solar-related invention and both of us were concerned about the changing climate of the country leading to droughts even in regions that had been wet during our youth.

    Steganalysis model for detecting and recovering stego images
    (2026) Nabirye, Barbra
    The National Information Technology Authority of Uganda (NITA-U) lacks effective steganalysis capabilities, leaving government systems vulnerable to covert data exfiltration and hidden communication channels exploited by malicious actors. While encryption secures message content, it does not conceal the existence of communication—a limitation that steganography overcomes by hiding information within innocuous digital media. This study designed, implemented, and experimentally evaluated a steganalysis model to detect, decipher, and recover hidden information from digital image files within the NITA-U context. Using an experimental design, the Least Significant Bit (LSB) technique was implemented in Python with OpenCV and Pillow. A dataset of 45 images was assembled from USC-SIPI, BOSSBase v1.01, and NITA-U operations. Evaluation metrics included PSNR, SSIM, MSE, chi-square analysis, classification metrics, and three feature detection methods (Shi-Tomasi, ORB, Harris). Results showed successful hiding and retrieval of text and image payloads without quality loss. The tool achieved PSNR values of 52.34–54.18 dB (exceeding the 40 dB threshold) and SSIM values of 0.9978–0.9984, confirming imperceptibility. Chi-square statistics (2.14, 1.87) fell below the critical threshold of 3.84, confirming statistical undetectability. No feature detection method distinguished stego images from cover images at significant levels (p = 0.68, 0.72; 94.7% match rate). The proposed model achieved 93.3% detection accuracy (F1 = 0.903) and significantly outperformed Steghide, OpenPuff, and F5 (ANOVA: F = 16.98, p < 0.001).

    Technology to facilitate agricultural financing.
    (Daily Monitor, 2017-10-05) Ladu, Ismail Musa
    Small holder farmers have for years been unable to access credit, hindering their transformation from subsistence farming to commercial agriculture, sector experts have said. According to the chief operations officer of aBiTrust, Ms. Josephine Mukumbya, whose organisation guarantees credit extended to farmers, small holders farmer financing comes with huge risks,
