Short Term Effects

The ecological impact of fire regimes on plant diversity and soil fertility has become a subject of intense discussion, especially in savannas where recurring incidences are common. This study assessed the short-term effects of early-season fire on herbaceous composition, dry matter yield and soil fertility in the Guinea savanna belt of Nigeria. Data on ground cover, dry matter yield (DMY) in plants and concentrations of C, N, P, K, Ca and Mg in soil were collected from 10 delineated subplots in the burned and unburned zones of four sites after annual wildfire had occurred. Ground cover was significantly higher in the burned zones, increasing progressively from January to April (dry season). Eleven herbaceous species in addition to 2 tree seedlings occurred and represented families of Asteraceae, Cyperaceae, Fabaceae and Poaceae. Digitaria nuda, Brachiaria lata, Daniellia oliveri and Aeschynomene indica were limited to the burnt zones while Cyperus tuberosus, Mariscus alternifolius and Rottboellia cochinchinensis were restricted to the unburned zones. DMY ranged from 0.32 g m-2 (Desmodium tortuosum) to 52.96 g m-2 (Megathyrsus maximus). Average biomass in the burned and unburned sites was 35.86 g m-2 and 28.42 g m-2, respectively. Soil C, N and P concentrations decreased (positive deterioration index - DI), while those of K, Ca and Mg improved (negative DI) in the burned sites. Burning altered the growth (ground cover) and composition of plant species in the short term, and could significantly influence soil nutrient dynamics in the long term, especially with recurring fire events.

Studies were conducted to investigate the effect of continuous cropping and NPK fertilizer on the growth and yield of cowpea (Vigna unguiculata (L) Walp) grown on soils from different management systems. The investigations were carried out in two parts. The first dealt with the effect of continuous cropping while the other focused on the effect of NPK fertilizer on cowpea. Representative soil samples were obtained at 0-15 cm depth from land which had been continuously cropped, under forest tree fallow, and secondary bush fallow. These were bulked, processed, and analyzed. Six (6) kg of each type of soil were weighed into 25 x 22 cm polybag of 500 gauge. The continuous cropping experiment involved three cropping cycles of 35days each of cowpea on the same soils from 3 cropping systems. In the second experiment, a 2 x 3 factorial involving 2 levels of fertilizers (0, 40 kg NPK/ha) and 3 sources of soil were carried out to test their effects on cowpea. The growth parameters measured were plant height, number of leaves/plant and number of branches/plant. Number of nodules/plant, number of pods/plant, dry matter and grain yield were also estimated. Successive cropping of soils significantly reduced cowpea growth. Cowpea plants grown on soils from continuously cropped land had the least growth performance. Number of nodules/plant increased with successive cropping. Higher dry matter yield was obtained from the continuously cropped land. A significant (r = +0.55) positive correlation was found between soil P and dry matter yield of cowpea. NPK fertilization had only significant effect on plant height at 10 WAP but not on other growth parameters measured. The highest grain yield was obtained from unfertilized secondary bush fallow soil. Sources of soil (soil management system) had significant effect on some of the agronomic characters of cowpea.

A trial was conducted in a field where a previous study suggested that a deficiency of manganese (Mn) or zinc (Zn) was created by the application of limestone, with the objective to confirm whether lime-induced deficiency is a potential problem in coastal British Columbia acidic soils. The trial involved the application and incorporation of limestone at two rates (9 and 19 Mg ha-1) in addition to a control with no limestone, and five foliar applications of Mn and Zn. The foliar applications included a control, Mn at two rates (2.3 and 4.5 kg ha-1), Zn at one rate (2.3 kg ha-1) and a combination of Mn and Zn, both at 2.3 kg ha-1. The trial was conducted at the same location over seven growing seasons (1979-1985), with the cauliflower grown in five of those years. The plot was fallowed in 1981 and 1983. The limestone treatments were applied in the spring of 1979, and again in the summer of 1981, while the foliar applications were applied to the plant each cropped season. Limestone increased plant dry matter yield in three years, decreased it in one, and had no effect in the other. The micronutrient applications did not affect dry matter yield in any of the years. Chemical analyses on the plants showed that limestone increased Ca and decreased Mn and Zn concentrations. The foliar applications increased plant Mn and Zn concentrations. Limestone, but not the micronutrient, applications influenced other element concentrations, with decreased concentrations of potassium, magnesium, sodium, strontium and rubidium. Iron and copper concentrations were not influenced by limestone applications. The decreased concentrations of nutrients could not account for the yield reduction by limestone applications in the one year, since concentrations of the nutrients measured in that year were not significantly different to concentrations in years when yields were increased. Further, basal applications of nutrients (nitrogen, phosphorus, potassium, magnesium and boron) had been applied to ensure that non-treatment nutrients were not deficient. Although monthly weather conditions were similar for one year of increased yield and one year of decreased yield, the influence of weather on the variable response by the crop could not be discounted as there could have been adverse weather conditions at critical stages of plant growth. Strontium and rubidium tended to respond to limestone similar to calcium and potassium, showing that their measurements have potential to further evaluate nutrient dynamics since they have characteristics similar to calcium and potassium, respectively. This field trial showed that limestone applications had many and variable effects on the availability of numerous nutrients and associated elements on cauliflower in addition to Mn and Zn. This showed the high degree of complexity of limestone applications on acidic soils.Key words: Liming, soil pH, Ca, nutrient elements, nutrient analogs

Aim: To study the effects of cocoa pod husk based compost: Soil mixtures on growth of cocoa (Theobroma cacao L.) seedlings. Study Design: The experiment was laid out in a Complete Randomized Design with four replications. Place and Duration of Study: The experiment was conducted at the main nursery of Cocoa Research Institute of Ghana at New Tafo - Akim (06°13’ N and 00°22’ W) in the Eastern Region of Ghana, between November, 2016 and December 2017. Methodology: Surface soil classified as Ferric Lixisols together with four compost types produced from cocoa pod husk, poultry manure and Panicum maximum was used to fill polythene bags. A Soil alone (T1) and Soil + standard foliar fertilizer (T2) with a four compost:soil mixture treatments namely T3 - 1:1 w/w, T4 - 1:2 w/w, T5 -1:3 w/w and T6 - 2:1 w/w were tested. Each of the four compost types was used for T3 to T6. Surface soil, poultry manure, compost and compost-soil mixtures were carried out using standard laboratory procedures. Mixed hybrid cocoa seedlings were raised and growth evaluated monthly. Results: Interaction effect was observed between compost types and compost-soil mixtures on dry matter yield of cocoa seedlings. Cocoa seedlings grown in T5 of compost 1 had the highest dry matter yield. Higher shoot: root ratio of cocoa seedlings were observed in compost 1. The order of desirability for the four compost types in terms of compost-soil mixtures was compost:soil (1:3 w/w) > compost:soil (1:2 w/w) > compost:soil (2:1 w/w) > compost:soil (1:1 w/w). CMPT1 will ensure more vigorous cocoa seedlings growth after transplanting and subsequently, higher establishment rate. Conclusion: The optimum mixture of compost and soil for growing cocoa seedlings under limited availability of fertile surface soil is compost 1 mixed with surface soil at the ratio of 1:3.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

N Rates

Sweet basil (Ocimum basilicum) is an important culinary herb in Virginia and other areas. The objective of this study, conducted during 1997, was to determine optimal N rate for fresh and dry matter yield. Seed of Broad Leaf sweet basil were direct-seeded on 18 June in rows 0.75 m apart in a RCBD design with 8 replications. Four N rates (0, 25, 50, and 75 kg N/ha) were used. Calcium nitrate (15.5% N) was used as the fertilizer source. All plants from 1-m row length from middle row of each plot were harvested by hand on 23 Sept. and fresh weights were recorded. The plant material was dried at 70°C for 48 h to record dry weights. The moisture content at harvest was calculated from fresh and dry weights. The fresh yields following 0, 25, 50, and 75 kg N/ha were 3.7, 5.4, 6.4, and 6.8 kg/m2, respectively. The yield difference between two highest N rates was not significant, however, both these rates had significantly higher yield than the two lowest rates. Similar results were also obtained for dry matter yields. The highest N rate of 75 kg N/ha resulted in significantly higher dry matter yield (1.3 kg/m2) as compared to the other three rates. The lowest dry matter yield was obtained after the control treatment (0.6 kg/m2). An opposite relationship between N rate and moisture content was observed when the highest moisture content resulted from control and 50 kg N/ha treatments. These results indicate that optimum N rate for sweet basil in Virginia is 50 to 75 kg/ha.
