Application Rates

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.

Compost is an important source of organic fertilizer that can be used to amend degraded soil to improve soil nutrient and crops yield. This experiment was to evaluate the effect of sawdust – piggery compost on soil properties, growth and yield of maize and it was carried out at the Ambrose Alli University Teaching and Research Farm, Emaudo, Ekpoma, Edo State. The experiment was fitted in a Randomized Complete Block Design (RCBD) with seven treatments and three replicates. The treatments were; control (0), 2, 4, 6, 8, 10 and 12 tonnes of sawdust – piggery compost per hectares (ha-1). Data collected were analysed using ANOVA and LSD was used to separate means. Soil nutrients were below critical levels and the application of compost improved fertility status of the soil. Growth parameters, dry matter yield, cob weight, grain yield and nutrient uptake were determined. It was observed that application of Sawdust – piggery compost significantly (p 0.05) increased the growth of maize compared to control. The application of 8 to 12 tonnes of sawdust – piggery compost significantly (p 0.05) increased the plant height, leaf area and stem girth of maize compared to other treatments. The application of 8 to 12 tonnes per hectares (ha-1) of sawdust – piggery compost significantly (p 0.05) increased the cob weight, grain and dry matter yield of maize compared to other treatments, however, the application of 10 t ha-1 of compost to maize increased grain yield of maize than others rate of applications with the yield value of 4.60 t ha-1. The uptake of nitrogen, phosphorus and potassium were higher with application of 12 tonnes of compost. In conclusion, the application rates of 10 t ha-1 of sawdust – piggery compost per hectare on nutrient depleted soils will improve the growth and yield of maize.

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.

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.

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.

Purpose: The aim of the study was to assess the effects of groundnut shell incorporation rates on the growth and yield of maize. Research methods: The study was carried out at the students’ demonstration farm of the Federal Polytechnic, Mubi, Adamawa State, in 2018. Seeds were sown on a prepared land treated with four (4) doses of groundnut shells (0, 25, 50 and 75 tons/ha) arranged in a randomized complete block design (RCBD), replicated 4 times. Each plot was marked out at 2.0 m length × 2.0 m width with 0.5 m gap between the replicated plots and blocks. Maize growth parameters were determined at 2, 4, 6 and 8 weeks after sowing and maize yield parameters were determined at 10 and 12 weeks after sowing (WAS). Findings: The groundnut shell application rates increased maize growth parameters such as, plant height, number of leaves per plant, leave area index, and stem girth, number of cobs per plant and cobs weight. The results revealed that plant height, number of leaves, leaf area index and stem girth were significantly (P≤ 0.05) influenced by the treatments, except for the control treatment at 2- WAS. The higher application rates (50 and 75 t/ha) of groundnut shell significantly (P≤ 0.05) influenced the plant growth components better than the 25 and 0 t/ha treatment rates. Research limitations: There were no limitations to report. Originality/Value: The results suggests that groundnut shell incorporation rate at 50 t/ha could be recommended as the most appropriate and profitable for high performance of maize plants in Mubi. The results generally suggest that maize plants may tolerate even higher rates of groundnut shell incorporation beyond the rates used in the study.
