    Assessing the productivity of Mchare Banana under drip irrigation and rainfed conditions in Northern Tanzania
    (NM-AIST, 2020-06) Kibona, Erick
    Mchare banana (Musa spp. AA genome) is a primary household’s source of diet and incomegenerating crop in the Northern part of Tanzania. Despite its importance and popularity, the yield records of Mchare - Huti Green (HG) cultivated under drip irrigation remain unavailable in the area. The overall objective was to quantify yield benefit of Mchare - Huti Green banana plant grown under full drip irrigation (FD) compared with rainfed - based (RF) in Meru District, Arusha Region. The performance of HG under FD and rainfed condition (RF) was quantified by recording the vegetative parameters and yield and yield components at harvest. The results for mean bunch weight in FD was 28.3 ± 1.75 kg plant -1 and that of RF 19.6 ± 0.97 kg plant -1 and fresh aboveground biomass (AGB) in FD was 78.81 ± 2.61kg plant -1 compared with RF 59.23 ± 1.06 kg plant -1 . The correlation coefficient for banana growth parameters and bunch weight indicated significant exemplified by pseudostem girth base (r = 0.48, < 0.001),1 m height (r = 0.38, < = 0.05) and mid-height (r = 0.51, <0.01), pseudostem volume (r = 0.38, < 0.01), height (r = 0.47 < 0.01), LA (r = 0.32 < 0.05) and LAI (r = 0.29 < 0.05) with correlation range 0.44 to 0.73 respectively. Conversely, for banana bunch weight and its components, correlation ranged from 0.30 to 0.50. Based on the current findings, banana plants under the FD outperformed those under the RF in terms of growth and yield. Therefore, the FD is hereby highly recommended for application in a banana for improved yield of banana in the study area.

    Growth comparison of Banana cv. Mchare (Huti Green) under full and deficit irrigation conditions in Northern Highlands, Tanzania
    (International Journal of Agronomy and Agricultural Research, 2020-02-15) Kibona, Erick; Mbega, Ernest; Mtei, Kelvin; Ndakidemi, Patrick
    Drip irrigation in banana farms is an uncommon practice as compared with other horticultural crops. Records for East African Highland Banana (EAHB) diploid (AA subgroup) cv Mchare-Huti Green (HG) cultivated under drip irrigation remain unavailable in the study area. The objective of this study was to assess the influence of drip irrigation on banana growth and bunch yield in the research site situated at 3°23′ 58″ S and 36°47′ 48″ E at an altitude of 1,188m above sea level in Arumeru District, Arusha Region, northern highlands of Tanzania . We investigated the performance of HG under Full irrigation (FI) and Deficit Irrigation (DI) treatments, to assess the influence of drought on banana growth parameters and bunch yield. The results exhibited significant differences within and between treatments of most tested variables. The mean bunch weight in FI was (28.3± 1.75kg plant-1) and DI (19.6±0.97kg plant-1) at (p<0.05) and fresh Aboveground biomass (AGB) in FI (78.81±2.61kg plant-1) and DI (59.23±1.06kg plant-1) at (p<0.05). The correlation coefficient in this study for growth parameters and bunch weight versus AGB indicated significant closer association exemplified by pseudostem girth, pseudostem volume height and bunch weight, with correlation 0.44 to 0.73. Conversely, for bunch weight and its components, correlation ranged from 0.30 to 0.50. The variation in allometric growth parameters calls for integrated soil water management in banana production to ensure the optimal level of available moisture for better performance from the vegetative phase to the generative phase.
