Taro, Colocasia esculenta (L) Schott., is a staple food for many people in Africa. Despite the numerous importance of the crop, it still remains an underutilized crop in Ghana with little information on many aspects of the crop, especially agronomic practices. This experiment was conducted to identify the effect of planting distance on growth and yield of two promising taro accessions. The experiment was laid out using the split-plot design arranged in Randomized Complete Block Design (RCBD) with three replications in which accessions (BL/SM/80 and BL/SM/16) were used as main plots and three planting distances (1 m × 1 m, 1 m × 0.75 m, and 1 m × 0.5 m) as subplots. Data were recorded on the 4th, 8th, 12th, 16th, 20th, 24th, and 28th week after planting (WAP) for growth parameters while yield data were taken at harvest. The results indicated that plant height (63.4 cm), petiole length (44.0 cm), number of leaves (4.7), leaf length (31.7 cm), and width (20.5 cm) were significantly ( P ≤ 0.05 ) higher in closely spaced plants than widely spaced plants at 4 WAP and 8 WAP for petiole length (70.3 cm) and in the 28th WAP where there was an accession effect on leaf length and number of suckers/plant. The highest corm yield/plant (0.63 kg) and total corm yield/ha (11.7 t/ha) in both accessions were achieved by the medium plant spacing (1 m × 0.75 m) and lower plant spacing (1 m × 0.5 m), respectively. Accession BS/SM/80 recorded the highest total yield/ha of 13.0 t/ha for 1 m × 0.5 m plant spacing. The higher number of suckers (8.1) was recorded by higher spaced plants. From the study, it was seen that growth parameters correlated significantly and positively with yield. It is therefore recommended that farmers in the area and those in similar production areas use a spacing of 1 m × 0.5 m for optimum growth and yield.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

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.

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg/ha P2O5) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in randomized block design in factorial mode to find out the effect on yield and quality of fodder cowpea [Vigna Unguiculata (L.)Walp.]. Growth parameters viz. plant height, number of leaves, number of branches, leaf length, leaf width and leaf stem ratio were improved with the application of 60 kg/ha P2O5 and 20 kg/ha ZnSO4. Application of 60 kg/ha phosphorus recorded 27.64 t/ha yield, which was 7.50 and 55.6 % higher than 40 kg/ha and no phosphorus application, respectively. Application of zinc in the form of ZnSO4 @ 20 kg/ha increased significantly the green fodder yield (25.89 t/ha). Interaction effect of phosphorus and zinc application was found significant with respect to green fodder, dry matter yield and nutrient uptake. Yield, phosphorus and zinc uptake in cowpea fodder were showing declining trend at combination of application rate more than 60 kg/ha P2O5 and 20 kg/ha ZnSO4.

Pepino melon (Solanum muricatum Ait.) is an exotic vegetable whose consumption is on the increase in Kenya due to its health and nutritional benefits. A study was conducted at Egerton University, Kenya in 2018-2019 to investigate the effect of NPK fertilizer rates (0, 100, 200. 300 and 400 kg ha-1) on growth and yield of field and greenhouse grown pepino melons. The experiment was laid in a randomized complete block design with three replications. Data was recorded on plant height, stem diameter, number of leaves per bush, number of branches, days to 50% flowering, fruit weight and total yield. Data were analyzed using analysis of variance with the SAS statistical package. Significant means were separated using Tukey’s Honestly Significant Difference at p ≤ 0.05. Results indicated that NPK fertilizer rates and growing environment influenced growth and yield of pepino melon. At 100 DAP plants grown in the greenhouse and supplied with 200 kg NPK ha-1 had a stem diameter of 14.01 mm which was significantly bigger p ≤ 0.05 compared to those grown in the field and supplied with 300 kg NPK ha-1 with a stem diameter of 11.71 mm in trial two. Application of 300 kg NPK ha-1 for field grown pepino melons gave the highest yield of 1102.48 kg ha-1 and 1060.55 kg ha-1 in trial one and two respectively. In conclusion, application of 300 kg ha-1 of NPK fertilizer for field grown pepino melon is recommended.

Production of leaf vegetables requires intensive soil nutrients management. A 3-year field experiment was carried out to assess effects of vermiculite application rates on the growth and yield of Brassica napus. The experiment was conducted during the 2016/17, 2017/18 and 2018/19 summer seasons at the Marondera University of Agricultural Sciences and Technology (MUAST) farm, Mashonaland East Province, Zimbabwe. Vermiculite was applied at five levels of 0 (control), 1, 2, 5 and 10 t ha-1 in a completely randomised block design (RCBD) with 3 replicates. Basal and top-dressing fertilizers were applied using the recommended rates in the study area. The B. napus leaf width, leaf length, fresh and dry matter yield, leaf nutrient concentration and N and P uptake were measured. Analysis of variance (ANOVA) at p = 0.05 was done to compare the effects of vermiculite application rates on growth and yield of B. napus. Growth parameters and yield of B. napus significantly (P <0.05) differed among the five levels of vermiculite. Application rates of 5 t ha-1 and 10 t ha-1 improved leaf width and length, fresh and dry matter yield of B. napus. Farmers may therefore apply 5 -10 t ha-1 of vermiculite in order to increase rape leaf yields. However, there is need for further researches to determine the optimum application rates of vermiculite are essential.

Intercropping is not a common practice in forage production in Sudan, in spite of its importance; farmers don’t know the potentiality of this type of cultivation and more experiments needed to adopt this type of cropping system and it is an example of biological interaction. A field experiment was conducted under irrigation for two consecutive seasons during 2013-2014 and 2015-2016 in the demonstration farm, college of Animal production, University of Bahri, Sudan to study the effect of intercropping of two leguminous forage crops (clitoria and phillipesara) cultivated with one non leguminous crop (Sorghum). Randomized complete block design (RCBD) was used. Yield of sole crops produced more forage, but the total yield (Over yielding) of the intercropped plants as revealed by land equivalent ratio was higher compared with the individual crops. Clitoria growth parameters (plant height, number of leaves and stem diameter) were not significantly affected by intercropping, but there was significant difference in plant population in the two seasons. Intercropping did not significantly affect growth parameters during the two seasons of Phillipesara except plant population and the first reading of plant height. Sorghum showed significant differences in plant population and some readings during the two seasons (the fourth reading of plant height in the first season, the first reading of number of leaves in first season, the fourth reading of stem diameter in the first season and the first reading of stem diameter in the second season).

A field study was conducted at Horticultural Research Farm, Institute of Agricultural Sciences of Banaras Hindu University, Varanasi, India during summer season of 2017-2018 to test the sole effect of phyto-hormones and micro-nutrients on growth of brinjal (Solanum melongena, L.). The thirteen treatments having six different concentration of phytohoromnes viz., T1 (20 ppm NAA), T2 (40 NAA), T3 (60 ppm NAA), T4 (25 ppm GA3), T5 (50 ppm GA3), T6 (75 ppm GA3), and six different concentrations of micronutrients viz., T7 (Boron 0.1%),T8 (Boron 0.2%), T9 (Boron 0.3%), T10 (Zinc 0.1%), T11 (Zinc 0.2%), T12 (Zinc 0.3%) and T13 (control-water spray) for a “Kashi Uttam” cultivar of brinjal were grown under randomized complete block design (RCBD) having three replications. The results findings indicated that treatment T4 (25 ppm GA3) had significant effect on growth parameters, mainly plant height, number of leaves, leaf length, leaf width, crop canopy, number of side roots and main root length. Similarly, yield parameters like number of fruits per plant, fruit weight, fruit yield per plant were found to be significantly superior under treatment T4 (25 ppm GA3). Number of branches per plant, stem diameter, main root length and fruit weight were found superior under treatment T1 (20 ppm NAA). Among the different concentrations of micronutrients treatment T9 (Boron 0.3%) and T12 (Zinc 0.3%) were found to be significant over control. It can be concluded that the phyto-hormones and micro-nutrients can be judiciously used for increasing the growth and yield of brinjal.
