Mazao Fertilizer Grown on Olasiti Soils from Minjingu-manyara, Tanzania]]>KisetuEliakira Medutieki TeveliChristina Ngomzee 1220131622A screen-house pot experiment was conducted to assess the
response of green gram (Vigna radiata L.) to the application of Minjingu
Mazao fertilizer (31% P2O5) on Olasiti soil, Manyara Region-Tanzania.
This study was prompted by very low or limited use of Minjingu Mazao fertilizer
by smallholder farmers in the country while yields turnout of most crops, green
gram inclusive, is not promising. The soil was clay with medium pH (pH 5.5-7.0)
and neutral reaction (pH 6.6-7.3). The results showed that the number of pods
and seeds increased from 3-6 and 7-9, respectively, at 40 to 160 mg per 4 kg
soil of fertilizer applied. Similarly, the tissue N and P increased with treatment
levels. The number of pods per plant and seeds per pod showed similar increase,
signifying the role of these nutrients in protein synthesis in leguminous plants
like green gram. Soil properties could be the spearhead to low responses obtained
at low (<80 mg per 4 kg soil) and high (>320 mg per 4 kg soil) rates of
Minjingu Mazao fertilizer applied. It was concluded that to optimize green gram
production in Olasiti soil, Minjingu Mazao fertilizer containing 31% P2O5
should be applied at a rate of 160-320 kg ha-1 while considering
other necessary agronomic practices. However, field studies to confirm the findings
of this study and verify the usefulness of this fertilizer brand to green gram
in Olasiti soil under field conditions could practically be the viable option
before its recommendation to the smallholder farmers.]]>Kisetu, E. and J.P. Mrema,20112011Kisetu, E. and J.P. Mrema,20102010pp: 719723Malik, M., Fayyaz-ul-Hassan, A. Waheed, G. Qadir and R.
