Growth of Ichiban Boshi Rice Variety for Different Number of Seedlings Per Hill

Authors : Hilali H. S. ; Ziba H. S.
Abstract:
One of the major constraints in the rice production for many African countries is the use of incorrect number of seedlings per hill. For example, in Tanzania, Uganda and Malawi; different plant numbers per hill are planted, calling the need to establish the common optimum number that will be recommended to farmers. In this study, three different numbers of seedlings per hill were planted; 2 seedlings per hill, 4 seedlings per hill and 8 seedlings per hill to assess their growth performance for plant height, number of tillers per hill and nitrogen content using leaf colour chart. Generally, the results did not show great variations for plant height, number of tiller per hill and leaf colour chart values in all treatments. However, the value of plant height and number of tiller per hill during early growth phases and that of leaf colour chart at late growth phase were significant higher (p˂0.05) for 8 seedlings per hill compared to 2 seedlings per hill and 4 seedlings per hill. Therefore, planting 8 seedlings per hill led to irregular growth pattern which might have undesirable effect in rice yield. On the other hand, 2 seedlings per hill proved optimal for all the growth parameters observed.

Growth Response and Bacteria Count of Broiler Starter Given Delonix regia Leaf Extract as a Natural Alternative to Antibiotics

Authors : Alagbe J. O.
Abstract:
This study was carried out to investigate the growth response and bacteria count of broiler starter given Delonix regia leaf extract (DRP) as a natural alternative to antibiotics. Two hundred (200) one day old commercial unsexed broilers of Ross-308 strain were randomly distributed into 4 dietary treatments of 5 replicates, each replicate had 10 birds. Treatment 1 (T1) was given Oxytertracycline at 0.30g/liter of water, T2, T3 and T4 were given DRP at 5ml, 10ml and 15ml/liter of water. Feed was formulated to meet the nutritional requirement of birds according to NRC (1994) and the experiment lasted for 4 weeks. Feed and water offered were offered ad libitum in a completely randomized design (CRD). Data on growth performance revealed that DRP had significant (p<0.05) effect on final body weight, body weight gain, daily weight gain and feed conversion ratio of the birds. Birds fed 15ml/liter DRP recorded significantly (p<0.05) higher body weight gain and superior feed conversion ratio than the control. The data on bacteria count indicated no significant difference (p>0.05) in the E.coli counts, a significant increase was observed in the Lactobacillus count (p<0.05). No mortality was recorded throughout the experimental period. Based on the results of this study, it can be concluded that DRP is an organic and effective herbal alternative to antibiotics because of its numerous bioactive chemicals and can be given to broilers up to 15ml/liter of water without any deleterious effect on the health and performance of the birds.
