Abstract

Field study was carried out at Umuowa Ibu1 via National Horticultural Research Mbato Okigwe Imo state, Nigeria, to evaluate the effect of cropping systems on growth and yield of castor southeastern Nigeria. The experiment was laid in a randomized complete block design. The treatments were nine castor based cropping systems. Data collected were subjected to analysis of variance. Significant means were compared with LSD at 5% probability level. Result showed that castor seed yield was influenced by cropping systems. Significant castor yield was recorded in the treatment of sole castor with 1289.34 and 1286.77 kg/ha in both cropping seasons, followed by 1288.43 and 1280.44 kg/ha recorded in castor + cowpea intercrop. The yield obtain from sole castor was not significant difference when compared to yield obtained from castor + cowpea and also in the treatment of castor + groundnut intercrop. The least castor seed yield; 1002.23 and 1007.23 kg/ha was recorded in castor + groundnut + garden egg intercrop. The yield of component crops decreases as number of crops in the systems progressed from two to three. Castor + cowpea + pepper cropping system had the highest land equivalent ratio (LER); 5.62 and 5.63 in both cropping seasons. The least LER: 2.23 and 2.24 was recorded in castor + groundnut treatment. Castor based cropping system with cowpea and pepper was recommended for higher land use efficiency.

Abstract

Methods and Aims: Field experiment was conducted at Ndikpa, Umuowa Ibu 1 via National Horticultural Research Institute (NIHORT), Okigwe Sub-Station Imo state, Nigeria in 2021 and 2022 to assess the effects of different soil amelioration on performances of cucumber and soil physico-chemical properties. The treatments were organic fertilizers (goat manure, cow dung, and wood ash) and recommended dose of inorganic fertilizer (250 kg/ha NPK), and control (no soil amendment). The experiment was laid out in a randomized complete block design and replicated thrice. Soil, growth, and yield data were collected and subjected to analysis of variance. Significant means were compared with the least significant difference at 5% probability level. Result: Results showed that cow dung had the highest organic matter content after harvesting, 2.55 and 2.43 % in 2021 and 2022, while the least organic matter content of 0.71% and 0.65 % was recorded in the control. Wood ash had significantly higher K levels after harvesting, while cow dung had the highest Ca. Goat manure had significantly higher Mg and Na than the other soil amendments. Treatment of NPK had significant fruit yield of 21.12 and 22.54 t/ha in both cropping seasons, respectively. The fruit yield recorded in goat manure was 20.23 and 20.81 t/ha in both cropping seasons, while 19.80 and 17.99 t/ha fruit yield were recorded in the wood ash treatment. The fruit yield obtained from NPK treatment was not significantly different when compared with yields obtained from goat manure and cow dung treatments. The least fruit yield, 5.12 and 6.03 t/ha in 2021 and 2022 was recorded in the control treatment. Conclusion: Based on the study findings, the application of organic soil ameliorations (cow dung and goat manure) was recommended for higher fruit yields and sound soil conservation practices for sustainable crop production in an ultisol.

Abstract

Background: Fluted pumpkin is a major leafy vegetable widely cultivated and consumed in Nigeria and other rainforest ecological zones of West and Central Africa. The cultivation of this crop faces challenges due to the low soil fertility of the ultisols found in southeastern Nigeria, making it difficult for farmers in the region to achieve bumper harvests of both foliage and pods.Aims: The experiment aimed to evaluate the response of fluted pumpkin (Telfaria occidentalis Hook. F) to varying rates of wood ash application in ultisol soils. This study seeks to determine the optimal wood ash level that improves soil fertility and enhances the growth and yield of fluted pumpkin, thereby providing sustainable agricultural practices for farmers in southeastern Nigeria.Methods: The field experiment was conducted to evaluate the effect of wood ash application on growth and yield of fluted pumpkin (Telfaria occidentalis Hook. F). The experimental treatments were four wood (dried oil palm rachis) ash rates; 0, 2, 4 and 6 t/ha. The treatment was laid in a randomized complete block design, replicated four times.Results: The results showed that the application of wood ash enhanced growth and yield of fluted pumpkin. The treatment of 6t/ha wood ash produced 19.71 t/ha foliar yield. The treatment of 4t/ha produced 18.63 t/ha foliar yield. The least foliar yield, 8.81 t/ha was recorded in the control treatment. Comparing the number of pods per plant, the treatment of 6t/ha wood ash produced significant number of pods per plant; 3.60, followed by 3.43 fluted pumpkin pods per plant recorded in the treatment of 4t/ha wood ash. The least number of pods per plant; 1.12 was recorded in the control treatment. The treatment that received 6t/ha oil palm rachis ash (OPRA) produced 26.81 t/ha pod, followed by 25.01 t/ha recorded in 4t/ha wood ash rate. The least pod yield; 7.44 t/ha was recorded in the control treatment. The study revealed that application of wood ash to fluted pumpkin could assist farmers in achieving bumper harvest in the study area. Farmer in the study area should adopt the application of 4t/ha of wood ash to fluted pumpkin.

Abstract

Background: Weeds pose a significant challenge to crop farming, particularly in cucumber production in Nigeria. They compete with cucumber plants for essential resources such as water, nutrients, and sunlight, which can lead to reduced crop yields. They harbor insects and disease organisms, serve as alternate host to pests, and compete with crops for nutrients, moisture, light, and space. Weeds cause damage to crops, reduce the yield and quality by competing with the crops, and cause harm to animals that feed on them. The production of cucumber has increased in Nigeria due to its importance, but it is still in short supply because of poor yield, which could be attributed to weed infestation.Aims: This study was conducted to investigate the impact of spacing and mulching on weed control and fruit quality of cucumber (Cucumis sativus) at various sowing dates in humid ecology.Methods: The experiment was carried out using a split-split plot arrangement layout in a Randomized Complete Block Design. The treatments consisted of three factors (time of planting, spacing, and mulching). The main plot was sowing dates (April, May, June, July, August and September), the sub plot was spacing (20cm x 50cm, 40cm x 50cm and 60cm x 50cm), sub-sub plot was mulching (no mulch, black plastic mulch, transparent plastic mulch, wood shaving) all were replicated 3 times. Result: The sowing date had a significant effect (p<0.05) on weed dry weight at 4 and 6 weeks after emergence. Sowing in April recorded the lowest weed dry weight (0.31g at 4 WAE and 0.79g at 6 WAE) in 2015 and (3.84g at 4 WAE; 3.16g at 6 WAE) in 2016. Cucumbers that were spaced at 20 cm x 50 cm recorded the lowest weed dry weight (8.53g at 4WAE and 4.60g at 6WAE) in 2015 and also in 2016 (10.36g at 4WAE and 5.33g at 6WAE). Black polythene recorded the lowest weed dry weight (2.87g at 4WAE; 1.79g at 6WAE) in 2015 and (2.95g at 4WAE and 1.88g at 6WAE) in 2016. Conclusion: The study revealed that effective weed control and high fruit quality were achieved by sowing early in April and May at closer spacing, combined with black polythene mulching. These practices recorded the lowest weed dry weight, while early sowing also produced better fruit quality. Therefore, the study recommends sowing early in April and May at closer spacing and using black polythene mulch for optimal cucumber production
