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.

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.

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.

Pleurotus ostreatus, an edible mushroom is an essential food product. Recognised as one of the cheapest sources of proteins, their high nutritional and anti-nutritional properties are of immense importance to humans. The present study evaluated the effect of sawdust and dried plantain leaves on the growth and yield of Pleurotus ostreatus. Sawdust and dried plantain leaves were composted into seven substrates; as single substrates and at different combinations. The composted substrates include sawdust 100 % (M0), Dry plantain leaves 100% (M1), Dry plantain leaves + sawdust at the ratio of 1:4 (M2), 2:3 (M3), 3:2 (M4), 1:1 (M5) and 4:1(M6). Growth parameters of interest assessed flush include mycelia running rate (MRR), area of pileus, length of the stipe, the girth of the stipe, fresh weight and dry weight, number of fruit body, total yield and biological efficiency. At the end of the three weeks spawn running period, M0 was overall best in supporting mycelia running rate with a mean MRR of 16.00 cm. M1 substrates produced mushroom with longer and bigger stipes (7.17 cm) at the first flush. A higher number of fruit bodies (82.66), total yield (130.35 g), and biological efficiency (43.45 g) were all seen in M0 substrates. Sawdust at 100 % (M0) proved to be the best substrate for the cultivation of Pleurotus ostreatus.

A study was conducted to determine the best agronomic practices for the cultivation of jerangau merah as a new medicinal crop. Jerangau merah is scientifically known as Boesenbergia stenophylla is a ginger plants that is highly endemic to the Borneo Highland. This understorey herb grows in cluster and under the heavy shades of forest canopies and perceived only the sunflecks that pass through the forest canopies. Jerangau Merah has been consumed by the locals for its medicinal values since decades ago. Generally, B. stenophylla is well known for its function as antidote for alcohol. Moreover, the B. stenophylla is also beneficial for rheumatic pains, remedies for stomach ache and toothache and as antiseptic wash as well. This herb is not propagate by the locals due to its sensitivity to sunlight and lack of agronomic information for B. stenophylla. Harvesting it from their natural habitat, however, seen the decline it its population size hence cultivation is essential. This paper aimed to determine the total nutrients, dry matter yield and phytochrome content of Bosenbergia stenophylla R.M. Smith under different light regimes. A study for determining suitable planting media for B. stenophylla was conducted at Universiti Putra Malaysia (UPM). The treatments are: i) (M1) with the ratio of 3:2:1 top soil: sand: organic matter, media ii) (M2) consists of soil mixture 3:2:1 placed in water-logged polyethylene bags and media iii) (M3) contained only leaf litters. The results showed that the herbs showed significantly higher number of shoots and leaves in the common soil mixture. But, better root development in media containing leaf litters. The study proceeded with field experiment at Ba’Kelalan to determine the effect of different shade levels and fertilizing regimes on growth. B. stenophylla was cultivated under two different levels of shade cloths: 70% and 90% level of shade and different fertilizing regimes (T1 as control, no fertilizer applied to the plants; T2, chicken dung; T3, NPKMg and T4, mixed of chicken dung and NPKMg). The study for determining the effects of different shade level and fertilizing regimes on seedling’s growth which conducted at Ba’Kelalan in factorial randomized completely blocked design (RCBD). The data collected for 9 weeks of planting which include nutrient content in soil, leaf, PAR and phytochrome content and growth parameters. Regarding the nutrient uptake, the results showed no interactions between fertilizing regimes and shade levels. There were no significant different in nutrient elements except for magnesium and potassium. Magnesium is essential for the formation of chlorophyll which ensure efficiency of photosynthesis when under higher light intensity. Among all the fertilizer treatment, it was showed that chicken dung amendment has higher nutrient uptake. Thus, it is recommended chicken dung should be added into the NPKMg for better nutrient uptake. Further study on suitable fertilizer rates apply to B. stenophylla should be taken into consideration. Moreover, plants cultivated under 70% have been higher and have higher dry matter yield than those plants cultivated under 90%. The result also revealed that there was significant different in chlorophyll content of B. stenophylla cultivated under 70% which treated either with chicken dung and NPKMG respectively. However, plants under 90% have higher chlorophyll content than those under 70%. Based on the results, plants under 70% shade was taller than those under 90% and there were significant difference in height among treatments under 70%.  It was observed plant treated with NPKMg was taller. This study showed that shade and fertilizers significantly affected the dry matter yield of B. stenophylla. Moreover, adding NPKMg to the treatments yields more dry matter content of jerangau merah. As for phytochrome content, there was no significant effect of fertilizer on phytochrome content. However, there was significant difference among the shade levels. 90% shade showed higher phytochrome content than those under 70%. In overall, both shade and fertilizer is important in cultivation of Jerangau Merah. 70% shade was observed to have significant effects on growth of jerangau merah and also more economical compared to 90%. Moreover, combination of organic matter and NPKMg also promote the growth of jerangau merah enhance the nutrient uptake efficiency of jerangau merah. However, further investigation of suitable fertilizer and application rate are required to determine suitable fertilizer for jerangau merah and application rate for optimum growth of jerangau merah.

Field experiment was carried out during the spring and fall seasons of 2019 at the Abu Ghraib Research Station of the Agricultural Research Office/ Ministry of Agriculture, was aimed to investigate the effect of plant growth inhibitors on growth and yield of several sorghum varieties .Randomized Complete Block Design within split plot arrangement with three replications was used. The main plot consists of three growth inhibitors (Cycocel, Ethiphon, and Mebiquat), which were added at stages six and eight leaf stage, in addition to the control treatment (distilled water only), the sub plot was included three cultivars (Mabrouk, Buhooth 70 and Giza 113). The results showed in both seasons significant interaction between cultivars and growth inhibitors in most of the studied traits. The plants of the variety Giza 113 sprayed with Ethiphon recorded the lowest period of reaching physiological maturity, the highest average dry matter yield, and the highest weight of 1000 grains (89.00 days, 17.32 ton ha-1, and 39.33 gm) respectively. The same variety recorded the highest content of chlorophyll in the leaves and the highest grain yield due to the effect of Mebiquat (49.50 spad, 3.93 ton ha-1. The cultivar Buhooth 70 with the effect of Cycocel achieved the highest average of dry matter yield of 33.27 ton ha-1.

ABSTRACTSilage cut twice annually (June and August) from a tetraploid red clover/grass sward and three times annually (May, July and September) from a low nitrogen (N) and high N perennial ryegrass/white clover sward was fed in proportion to dry-matter yield from each cut, over a 10-week period, each winter for 3 years to castrated male cattle of initial live weight 401 kg in year 1 and 425 kg in years 2 and 3. The silages were supplemented with 0, 1, 2 and 3 kg concentrate per head daily.Total dry-matter yield from the red clover/grass sward was similar to that from the perennial ryegrass/white clover sward (high N grass) receiving 360 kg N per ha but the digestibility, particularly of first cut material was much lower. Dry-matter production of the low N grass/white clover sward was 0·73 of high N grass sward and produced silages of similar digestibility and fermentation.Dry-matter intakes by the cattle were higher on the legume-based silages in years when clover made a worthwhile contribution to total yield, but this did not significantly improve utilization or animal performance compared with high N grass silage. Mean daily carcass gain per head on red clover/grass silage was 0·41 kg which was significantly less than the 0·61 kg on white clover/grass silage and 0·59 on high N grass (P < 0·001). Carcass output from red clover/grass silage was 618 kg/ha and 629 kg/ha from white clover/grass, both of which were significantly less than the 863 kg/ha from the high N grass silage (P < 0·001). Dressing proportion was also significantly poorer in animals fed red clover/grass silage compared with the other silage types.
