“…The lack of significant differences in grain yields between the BR and SP methods of P fertilizer application in the first season is consistent with findings by Okalebo et al (1990). Other agronomic studies in Africa indicate occasional but not consistent superiority of SP compared to BR of P fertilizers .…”

Simultaneous deficiencies of nitrogen (N) and phosphorus (P) which limit crop production in western Kenya can be overcome through a combined application of organic and inorganic fertilizers. An experiment was conducted with maize (Zea mays) for two seasons to compare two methods of applying inorganic P fertilizer (broadcast versus spot) in a factorial combination with three N sources, i.e. farmyard manure (FYM), Tithonia diversifolia green manure (tithonia) and urea. Net financial benefits of the tested practices were computed using partial budgeting. Maize yield was not significantly affected by the P fertilizer application method in the first season, but the broadcast method was generally superior to spot application in the second season. The three N sources produced maize yields that were comparable in both seasons. FYM integrated with P fertilizer applied using the broadcast method, however, had the highest cumulative net benefit and was therefore the most economically attractive input combination.

“…The significant increase in plant height might also be because phosphorus improved the root development which had a great effect on the plant height, probably due to advanced root system that increased nutrient absorption (Hussain et al, 2006). These findings are in conformity with those by other scientists (Okalebo et al, 1990;Sahoo and Panda, 2001) who found significant increase in height of maize with P application over that of the control. In another study similar results were reported where application of phosphorus fertilizer ISSN 2166-0379 2017 increased plant height gradually in two sorghum cultivars (Khalid and Muhammad, 2003).…”

Finger millet production on more than 30% of world arable land is limited by P availability and more than 70% in the semi-arid and marginalized areas which covers most of the Sub-Saharan Africa. Phosphorus is one of the most important elements significantly affecting plant growth and metabolism. Three finger millet varieties (U-15, P-224 and Ikhulule) were evaluated under four P fertilizer levels (0, 12.5, 25 and 37.5 kg ha (13) at Kakamega site. The highest rate led to the greatest vigor in both sites for both seasons while the control had the poorest vigor. Variety P-224 showed the highest lodging count with 32 out of 246 plants per experimental unit during the rainy season at Kakamega. The unit increase in grain yield was positively and significantly correlated with increased values of the harvest index (r=0.375), number of leaves (r=0.393) and plant height (r=0.431) but negatively and significantly correlated to the 1000-grain mass (r=-0.578) and lodging (r=-0.233). The best phosphorus treatment for most of the parameters was 25 kg ha -1 P 2 O 5 at Alupe while maximum levels of the study parameters were realized under the 37.5 kg ha -1 P 2 O 5 rate at Kakamega.

“…Finger millet (Eleusine coracana L. Gaertn) is one of the important millets grown extensively in Dharmapuri District. It is a hardy crop, has good adaption to wide range of environment especially heat, drought, marginal and degraded soils (Okalebo et al, 1991). Finger millet is the principal food grain of the rural population in India, especially in South India.…”
