A research study on the response of different sweet potato cultivars to different levels of NPK 15:15:15 in Igbariam Anambra State, Nigeria was was conducted between May and July 2018 at the teaching and research farm of the Department of Crop Science And Horticulture, Faculty of Agriculture, Chukwuemeka Odumegwu Ojukwu University (COOU) Igbariam Anambra state.It was a factorial experiment laid out in Randomized Complete Block Design (RCBD) with four replications. Three varieties of Sweet Potato viz; TIS 87/0087, Umuspo 1 and Umuspo 3 were planted. Four fertilizer treatments NPK 15:15:15 at 200kg/ha 300kg/ha 400kg/ha 0kg/ha were applied four weeks after planting. Data was collected at 2 weeks’ interval on growth parameters and yield parameters. Analysis of variance was used to know the significant effect of blocking and treatment on various parameters evaluated and separation of treatment means was done using Fisher’s least significant difference. Sweet potato variety Umuspo 1 was found to produce significantly (P<0.05) large number of leaves and was well established compared to other varieties. Umuspo 3 and Tis87/0087 produced longer vine than Umusopo 1. Generally, increase in fertilizer rate resulted in increase in vegetative growth. TIS87/0087 was best in the overall yield performance when compared to other cultivars. Therefore, NPK 15:15:15 at the rate of 300kg/ha can be recommended for the production of TIS/87/0087 in the study area, further breeding work is also recommended.

A field study was carried out during the 2016 cropping season to determine the effect of planting density on the growth and yield performance of two varieties of millet at Ekpoma. Gero badeggi and Gero bida varieties were sown at three densities (111,111, 222,222 and 333,333 plants ha-1). The experiment was a 2 x 3 factorial scheme laid out in a randomized complete block design (RCBD) with three replicates. The result shows that planting density had no significant effect on the growth parameters measured. However, Gero badeggi planted at 111,111 plants ha-1had the tallest plants, highest number of leaves/plant and stem girth while Gero bida planted at 333,333 plants ha-1 gave the shortest plants, least number of leaves/plant and stem girth, respectively. There was no significant difference in flowering trait amongst densities, but the varieties differed markedly in days to 50% flowering. Increasing planting density significantly (P<0.05) increased the forage yield. However, crops sown at higher densities had higher forage yield than the low density. The differences in observed between varieties were significant in some of the studied characters and thus millet sown at 111,111 and 333,333 plants/ha is recommended for millet production in the area.Keywords: Millet, planting density, growth and forage yield.

<p>Improper intercropping of <em>Elaeis guineensis</em> with other crops has impaired the growth and development of the oil palm due to competition for environmental resources. The study was conducted to investigate the impact of intercropping on the growth of juvenile oil palm for 2 years. The research commenced during the rainy season of 2016 at an established juvenile oil palm plantation in Ala, Akure-North Local Government of Ondo State. Four fruit vegetables were intercropped separately within the alley of the plantation at 1, 2 or 3 m away from the oil palms in a randomized complete block design. Growth parameters of the juvenile oils were assessed. Results revealed that at 16 weeks after intercropping (WAI), the intercropped oil palm recorded better growth performance with higher canopy spread, number of frond, number of leaflets and trunk height (218.20, 37.00, 87.48 and 38.17 cm) respectively, than the sole oil palms (214.67, 32.83, 72.89 and 31.67 cm) respectively. There were no significant difference in all the growth parameters examined except canopy height (<em>p</em> &lt; 0.05). Juvenile oil palm cultivated in rainforest agroecological zone of Nigeria can be intercropped with fruit vegetables without any deleterious effect when intercropped at minimum of 1 m away from the oil palms.</p>

Vegetative parameters of eight M3 (third mutant generation) lines of sesame were evaluated under rain fed condition. The seeds of the lines were sown alongside their respective controls using a randomized complete block design. The eight lines were generated from three parental stocks: NCRIBEN-04E (V1), NCRIBEN-01M (V2) and NCRIBEN-03L (V3). The three parental stocks were exposed to different doses of gamma irradiation from cobalt-60 source. 04E-550-G2-3 had the highest plant height (57.40) at the 6th week which was significantly different (P<0.05) from the three checks. 03L-450-G2-2 had the highest petiole length (12.45cm) which was significantly different (P<0.05) from the checks except check three (12.25cm) which was not significantly different (P>0.05). 03L-450-G1-2 had the highest number of leaves (91) and consequently highest number of branches (5.60). Although the number of leaves were significantly different (P<0.05) from Check three (54.60), there was no significant difference (P>0.05) between the number of branches and check three (5.40). The results obtained for vegetative parameters of M3 lines of sesame suggests that some of the genotypes could be used as potential parents for future breeding programmes aimed at improving sesame lines.

Peanut (Arachis hypogaea)  is commonly grown during the dry season and most farmers used the native variety. Growth retardants such as paclobutrazol (PBZ) was found to increase yield of some important crops. A study was conducted to determine the effect of different levels of paclobutrazol on the peanut yield of Asha and Farmers’ variety during the wet season. The experimental area was laid out using Randomized Complete Block Design (RCBD) factorial. Treatments were replicated thrice. Data were analyzed by Analysis of Variance (ANOVA) and  the Honest Significant Difference (HSD) test was used to compare treatment means. The increasing level of PBZ increased the number of pods of Asha by 29.97% while the most number of seeds was obtained from farmers’ variety. Applied PBZ Asha at 150mg/L recorded the highest shelling percentage that is 16.19% higher when compared to the untreated. Paclobutrazol application significantly increased seed yield of Asha and farmers’ variety by 43.34% and 20.86% at 150mg/L and 75mg/L, respectively. The increase in yield was due to the observed reduction in plant height and stem growth which possibly enhanced assimilate partitioning to pods. Asha applied with PBZ at 150mg/L obtained the highest seed yield of 4.2 tons/ha. Keywords— Agriculture, yield, peanut, paclobutrazol, experimental design, Pampanga, Philippines

There is significant variation in yield of storage roots and vines of sweet potato (Ipomoea batatas) among farmers due to use of different cutting positions and pruning of vines at different levels. This study was carried out to establish the cutting position and the vine pruning level that give the best yield of both the storage roots and vines. The study was conducted in a 3x3 factorial arrangement in Randomized Complete Block Design (RCBD) with three replications. Treatments included cutting position at three levels (apical cutting, middle cutting and basal cutting) and pruning at three levels, 0%, 25% and 50% respectively. Pruning was done. 50 days after planting. And storage root harvesting was done 100 days after planting. The two measurements were summed up to give the total vine weight. Storage root length, diameter and weight were measured at 100 DAP. Storage root length indicated significant difference (P<0.05) only among cutting positions with highest mean length (16.20 cm) obtained from apical cutting and the lowest (11.98 cm) from basal cutting. Storage root diameter, storage root weight and vine weight indicated significant interaction (P<0.05) of cutting position and vine pruning level. Highest mean root diameter and root weight were obtained from middle cutting and 25% vine pruning level, with the lowest being obtained from basal cutting and 50% vine pruning level. Highest vine weight was recorded from middle cutting and 50% vine pruning level, with the lowest being recorded from basal cutting and 0% vine pruning level. Both middle and apical stem cuttings can be recommended for higher storage root and vine yield. Vine pruning at 25% can be adopted for higher storage root yield while pruning at 50% can be suggested for higher vine yield.

Abstract A field experiment was conducted on sorghum (Sorghum bicolor (L.) Moench cv.) under three cutting system to determine the effect of nitrogen on growth and yield at University of Agriculture Faisalabad, Pakistan, during the season 2010-2011. The experiment was laid out in Randomized Complete Block Design (RCBD), using three replications. There were four levels of nitrogen 0, 50, 75 and 100 kg N/acre in the form of urea. The growth parameters like plant height, number of leaves, leaf area is determined periodically. First reading taken after 20 days of sowing while second and third was taken after 15 days of first cutting. Yield parameter like plant population, fresh and dry weight was determined in three cuttings. Results showed that increasing nitrogen dose increased all growth attributes. Results revealed for first, second and third cuttings showed significant differences at all growth attributes. Thus, the maximum plant height was observed in N4 (100 kg N/acre), having plant height 193.92, 195.24 and 192.79 cm in first, second and third cutting, respectively, which was followed by the treatment N3 (75 kg N/acre), having 179.70 cm in first cutting, while second and third cutting have same plant height 168.62 cm. The exception was the plant population showed non significant behavior in second and third cutting while number of leaves per plant in second cutting only and protein % in third cutting showed non significant difference with nitrogen application.

A research study on the agronomic attributes of five okra genotypes for Okra production were evaluated for growth and yield at the teaching and research farm of the Department of Crop Science and Horticulture, Faculty of Agriculture, Chukwuemeka Odumegwu Ojukwu University (COOU) Igbariam Anambra state. The experiment was conducted using a randomized complete block design (RCBD) with 4 replications using 3m row plots. The total field size was 187 m2 (0.00187 ha) and a plant spacing of 0.60m × 0.30m was used. There was no significant difference in the treatment means for all the parameter studied, however, result from the seedling characteristics revealed that Nkwelle Okra was the earliest to emerge (4.25 days) while Awkuzu okra was the last to emerge (6.00 days). The experiment showed that Awkuzu okra was earliest to flower at 60.30 days after planting while Nteje Okra was the last to reach 50% flowering at 70.10 days after planting. Awkuzu Okra had the highest number of pods per plant (11.80), pod weight (50.90g) and yield t/ha (0.00005t/ha) while the least was Nteje Okra for number of pods per plants (6.50), pod weight (29.60g) and yield t/ha (0.000029 t/ha). Therefore, a further genetic study was recommended for the studied genotypes to produce hybrid and synthetic cultivar for the production of okra in the study area.
