Greengram productivity has been improved by application of farmyard manures in the last two decades; however, these manures are not readily available as at when needed. In some cases, they are available but in limited supply. Kolgrace bio-fertilizer, a novel commercial product of the Association of Organic Agricultural Practitioners could serve as a superior alternative to farmyard manures. Hence, a field experiment was carried out at the Teaching & Research Farm of the Department of Agronomy, University of Ibadan, Nigeria during the 2015 cropping season to evaluate the effects of five rates (0.00, 0.25, 0.50, 1.00, and 2.00 t ha–1) of Kolgrace bio-fertilizer on the performance of greengram. The aim was to determine the optimum rate of application of this biofertilizer for greengram production. The experimental design was a randomized complete block design with four replications. Data were collected on growth and yield traits, and were subjected to analysis of variance. Results showed that Kolgrace rates significantly (p < 0.01) influenced all the traits measured with exception of fresh pod yield (FPY). Plant height (112 cm), number of leaves (87), stem girth (1.43 mm) and number of flowers (10) at 8 weeks after planting (WAP) were significantly highest with the application of 0.5 t ha–1 whereas, 0.25 t ha–1 gave best results for number of pods (42) and pod yield (3.85 t ha –1). The application of 0.5 t ha–1 is, therefore, recommended if the interest of the farmer is sprout, fodder or green manure, and 0.25 t ha–1 if the interest is for seed production.

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.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

Field experiment was carried out during 2010 rainy season to find the effect of seeding rate on the growth and yield of okra (Abelmuschus esculentus) in Zuru Northern Guinea Savannah. Zuru is located in Zuru Local government area of Kebbi State (Latitude 11o 251 to 11o 551 North and Longitude 4o 51 to 5o 251 East of the equator). The experiment consisted of three treatments that is planting okra at one plant per stand (S1), two plants per stand (S2) and three plants per stand (S3). The experiment was laid out in randomized complete block design (RCBD) and the treatments replicated three time. The result of the experiment has shown that plant height and number of leaves/plant at 3, 6 and 9 weeks after planting (    WAP) were significantly influenced by seeding rate (P<0.05). At 3, 6 and 9 WAP tallest plants were obtained from okra plants planted at three plants/stand (27.83, 54.0 and 77.0cm) respectively followed by okra planted at two plant/stand (24.77, 50.67 and 74.33 leave/plant respectively ). However, more number of leaves/plant were obtained from okra plant at one plant/stand (9.67, 24.67 and 48.0 leaves/plant respectively) followed by okra planted at two plants/stand (8.33, 18.33 and 36.33 leaves/plant respectively). Seeding rate had significant influence on time of 50 percent flowering with one plant/stand first attaining 50 percent flowering stage just within 36.33 days followed by okra planted at two plants/stand (38 days). The mean fresh fruit yield of okra was also significantly influenced by seeding rate with the highest yield of fresh fruits obtained from three plants/stand (83.34/ha) followed by okra planted at two plants/stand (55.56/ha). However, the result of the findings recommends that, okra should be planted at two plants/stand for medium sized and marketable okra fresh fruits since at three plants/stand leads to the production of undersized fresh fruits which do not often attract customers. At one plant/stand, there seemed to be early fruiting and bigger sized fresh fruits but low total yield due to underutilization of land resource/space. Planting at one plant/stand should therefore be avoided

The experiment was conducted in the Dekarhaor of Noagaon village under South Sunamganj Upazila of Sunamganj district during November 2017 to February 2018 to observe the effect of nutrients management on growth and yield of cauliflower hybrids. Two Hybrids namely ShiraGiku (V1) and Rupali (V2), and four combinations of nutrients, viz. (i) recommended rate of N-P-K-S-Zn-B @ 180-80-180-28-4.5-2.1 kg ha-1(F1), (ii) F1 + 25% N-P-K- S-Zn-B of F1 (F2), (iii) F1 – 25% N-P-K-S-Zn-B of F1 (F3), and (iv)  cow dung @ 10 t ha-1 (F4)  was conducted in a factorial randomized complete block design (RCBD) and replicated thrice. Plant height (cm), numbers of leaves plant-1, leaf length (cm) and leaf breadth (cm), and spreading diameter (cm) were collected at 15 days intervals, while the yield data were recorded at harvest. The parameters were significantly varied due to hybrids and fertilizers packages. Higher gross yield (42.52tha-1) was found in Shira Giku and lower (42.12 t ha-1) from Rupali. Higher curd yield of 25.17 t ha-1 was obtained in Shira Giku than Rupali (9.61 t ha-1). The highest gross yield of 44.45 t ha-1 was obtained when the crop was treated with cowdung @ 10 t ha-1 followed by recommended fertilizer rate (F1). The curd yield of 18.19 t ha-1 was obtained with 25% less than recommended fertilizer rate of application (F3). The highest gross yield of 52.93 t ha-1 was obtained in V1F1 combination and the lowest of 30.10t ha-1in V2 F1. Results revealed that the Hybrid ShiraGiku with recommended dose of fertilizer (180-80-180-28-4.5-2.1 kg ha-1N-P-K-S-Zn-B) performed the best in comparison to other treatment combinations.

Aim: This study evaluates the effects of soil amendment with organic manure-OM and agricultural lime-AL on the growth and yield of Phaseolus vulgaris and Vigna aconitifolia grown on soils with 3 different pH (locations) in Southern Cross River State. Study Design: The study was laid in randomized complete block design (RCBD) with three replications. Place and Duration of Study: This study was carried out at the Greenhouse, Department of Plant and Ecological Studies, University of Calabar for a period of 3 months. Methodology: The three locations were: Akamkpa with pH 4.0, Calabar Municipality with pH of 7.0 and Odukpani with pH of 9.0. The treatments were; control (0 g), OM1 (100 g organic manure), OM2 (200g organic manure), AL1 (100 g agricultural lime), AL2 (200 g agricultural lime), OM1 + AL1 (50 g organic manure + 50 g agricultural lime) and OM2 +AL2 (100 g organic manure and 100 g agricultural lime. Results: Results obtained from the physico-chemical properties of the soil before treatment application revealed low nutrients and minerals which increased after treatment application. Six weeks after planting, there were significant increase in plant height (p<0.05) of P. vulgaris and V. aconitifolia on soil from Akamkpa (169.66 cm) and Odukpani (146.63 cm) treated with OM2 + AL2 compared to 43.77 cm and 71.77 cm from control. Leaf area, petiole length, number of leaves were all significantly improved especially at 8 weeks after planting. Fresh weights of leaf, stem and root revealed higher yield (p<0.05) at the final harvest recorded as 8 weeks after planting than the amount at 4 weeks after planting. The results obtained from the pod number, pod weight and number of seed showed significant improvement after treatment application. Conclusion: The findings of this study strongly support the use of organic manure and agriculture lime as affordable and accessible sources of manure especially for our local farmers.

Critical P eriod of W eed Control (CPWC) is the period in crop growth cycle during which w eeds must be controlled to prev ent unacceptable yield losses.T w o sets of treatments w ere imposed to represent both increasing duration of w eed interference and the length of the w eed-free period measured after germination. The first set of treatments consists of increasing duration of w eed interference by delaying w eed control from the time of crop emergence up to predetermined w eek (w eedy up to 2,4,6,8,10 and 12 w eeks after germination (W AG) of Kala Zeera ) . The second set of treatments established six lev els of increasing length of the w eed-free period (w eed free upto 2, 4, 6, 10 and 12 W AG). Besides tw o controls (W eed free and w eedy check). These comprised of 14 treatments which w ere laid out in randomized complete block design with three replication. It w as rev ealed that v ariation in Kala zeera seed yield due to w eeds is upto 88% and yield gets reduced as low as 48 % in w eedy check plots. Early w eed competition does not hav e hav e profound influence in Kala zeera crop.According to av erage data of tw o y ears inv estigation, it w as concluded that W eeds emerging betw een 6-12 W AG appear to be most detrimental to Kala zeera growth and yield and hence qualifies critical stage for w eed competition.

An experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during  the period from November 2010 to January 2011 to study the effects of cowdung and potassium on growth and yield  of Kohlrabi. The experiment consisted of three levels of cowdung (0, 20 and 40 t/ha) and four levels of potassium (0,  20, 50, 80 kg /ha). The experiment was laid out in randomized complete block design with three replications. All the  parameters were significantly influenced by application of cowdung and potassium. The highest plant height (44.65  cm), number of leaves per plant (12.11), length of largest leaf (37.54 cm), and breadth of largest leaf (18.66 cm) were  obtained from the highest dose of cowdung and potassium applied (40 t cowdung + 80 kg K/ha) while the lowest  plant height (33.64 cm), number of leaves (9.01), length of largest leaf (27.94 cm), and breadth of largest leaf (11.00  cm) were obtained from control treatment combination. The highest fresh weight of leaves (49.33 g), fresh weight of  knob (328.66 g) and fresh weight of roots (66.55 g) per plant were also recorded under the treatment combination of  40 t cowdung + 80 kg K/ha, while the lowest fresh weight of leaves (22.11 g), fresh weight of knob (136.00 g) and  fresh weight of roots (23.33 g) were obtained from control treatment combination. Similarly, the dry weight of leaves  (19.34%), knob (15.19%) and roots (32.75%) were highest under the same treatment combination of 40 t cowdung +  80 kg K/ha and the lowest dry weight of leaves (11.71%), dry weight of knob (7.38%) and dry weight of roots  (15.29%) were obtained from control treatment combination C0K0. The marketable yields of knob per plot (7.86 kg)  and per hectare (39.58 tons) were also the highest under the treatment combination 40 t cowdung/ha and 80 kg  potassium per hectare.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12035   J.
