Abstract
Millets are important natural grain source for wild and game birds and the
domesticated varieties are good sources of grain for human and livestock nutrition
as well as summer forage. Unlike sorghum, millet seed has less anti-
nutrient factors and is a better choice for animal feed formulations. Pearl
millet is an example of such millets and has both forage- and grain-type varieties.
However, opportunities exist for dual use of millet for grain and residue
for forage. In this study two millets: Pennisetum glaucum (L.) R. Br.
(Pearl millet var. TifGrain 102) and Panicum ramosum (L.) (Browntop millet)
were evaluated for their response to potassium (K) and manganese (Mn)
fertilizer. The experiment was a randomized complete block with treatments
in a split-split arrangement. Potassium and Mn were supplied as K fertilizer
(0-0-60) and manganese sulfate (MnSO4·2H2O), respectively. Potassium and
Mn fertilizer rates and their interaction with each other and variety had no
effect on determined parameters. TifGrain 102 grain yield averaged at 5900
kg·ha−1 was significantly greater than 4680 kg·ha−1 obtained for Browntop
millet. While grain oil contents were similar, Browntop grain had greater
contents of crude proteins. And except for K, Browntop seed had greater
contents of all determined macro-and micronutrients. Residual stalks of
Browntop had greater forage crude protein, total digestible nutrient (TDN)
and lower acid detergent fiber (ADF). Browntop residual material had greater
quantities of estimated net energy for growth (NEG), lactation (NEL), maintenance
(NME). While TifGrain 102 residual stalks had greater contents of P
and K, it had significantly lower contents of Ca, Mg and S compared to
Browntop. Overall, while these two millets have shown good potential for
dual use, Browntop may offer a better choice for high quality seed and residual
stalks for forage.
