Effect of nutrient sources on cucumber production in different substrates

The research was conducted in two successive seasons to compare the effect of nutrient sources, organic manure and inorganic conventional nutrient solution, in cucumber production performed with different local substrates. In fall, the experiment was designed to test three factors, namely cultivar [(a) Armada, (b) Gordion], nutrient source [(a) inorganic nutrient solution, (b) solid organic manure] and substrate [(a) 3 + 1 perlite + clinoptilolite, (b) 1 + 1 perlite + clinoptilolite, (c) 3 + 1 tuff + clinoptilolite, (d) 1 + 1 tuff + clinoptilolite, v/v]. Results showed that organic manuring decrease the total yield by 22.4% in comparison to inorganic nutrient solution. In organic manure treatment, vigorous variety (Armada) gave higher yield than less vigorous variety (Gordion). In the spring season, the tested factors were decreased to two and tested as nutrient source [(a) inorganic nutrient solution, (b) solid organic manure, (c) organic nutrient solution] and substrate. Armada was the only cultivar. Compared to that of the inorganic nutrient solution, total yield was reduced by 10.9% in the organic nutrient solution system and 31.3% in solid organic manure treatment. [1]

Reduction of CO2 emission by improving energy use efficiency of greenhouse cucumber production using DEA approach

The main purpose of this study was to determine energy use efficiency in greenhouse cucumber production using a non-parametric production function. Energy use efficiency of greenhouse cucumber producers was studied and degrees of technical efficiency (TE), pure technical efficiency (PTE) and scale efficiency (SE) were determined using data envelopment analysis (DEA). Additionally, wasteful uses of energy inputs were assessed and energy saving from different sources was computed. Furthermore, the effect of energy optimization on CO2 emission as one of the major greenhouse gases (GHG) was investigated and total amount of CO2 emission was calculated. Average of total input and output energies were calculated as 1667164.8 MJ ha−1 and 151846.2 MJ ha−1. Energy use pattern indicated that natural gas and electricity were the main energy inputs. Based on the results 24.46% (407916.3 MJ ha−1) of overall energy resources can be saved if the performance of inefficient farms is enhanced. Additionally, the total CO2 emission was calculated as 45177.3 kg CO2eq ha−1. Finally it was concluded that, by energy optimization the total energy consumption can be reduced to the value of 1,259,248 MJ ha−1 and correspondingly the total CO2 emission is reduced to value of 34995.9 kg CO2eq ha−1.

A PDA-based record-keeping and decision-support system for traceability in cucumber production

For the small-scale and scattered fresh cucumber production in China, the result that production record-keeping and its transfer are inefficient have prevented the wide application of traceability systems in China. With the mobility and computability, Personal Digital Assistant (PDA) provides a new way for agricultural information collection to solve the above problems. Thus a PDA-based Record-keeping and Decision-support System (PRDS) for traceability in cucumber production was developed on Windows Mobile platform invoking a Geographic Information System (GIS) control. For improving the decision making feasibility of PRDS, the fertilization recommendation model and pesticide usage early warning model were developed by using the Technical Specification of Balanced Fertilization by Soil Testing and the Guideline for Safety Application of Pesticides in China. The architecture of PRDS was provided. With Unified Modeling Language (UML), a requirement model including two types of users and 17 use cases was described, and a static class model was also designed, which consisted of table class, table operation class, algorithm class and interface class. Based on these models, the functions of system setup, map management, data management, production record-keeping and decision-support and query, etc., were implemented by adopting Hosting MapInfo MapX Mobile Controls on the .NET Compact Framework 2.0, and the data synchronization was realized by Remote Data Access (RDA). Two agricultural production enterprises were chosen as case study to evaluate the system by questionnaires. The results show that the efficiency of production record-keeping and decision-support is improved by the simple and friendly system. [3]

Effect of Cow Dung and Urea Fertilization on Soil Properties, Growth, and Yield of Cucumber (Cucumis sativus L)

In this work, effect of cow dung and urea fertilization on soil properties, growth and yield of cucumber was evaluated. Four different rates of treatments [12 kgplot-1 cow dung (CW), 391 g ureaplot-1 equivalent to 150 kgha-1, 6 kg cow dung + 196 g urea equivalent to 75 kgha-1 thoroughly mixed (CWU) and CO kgplot-1 (control that received no treatment application)] were used. The treatments were applied following a randomized complete block design (RCBD). Results obtained showed significant differences between the treatments in the soil and in agronomic parameters assessed. The CWU treated plots recorded the highest value in all growth parameters measured. The values of the fruit yield vary from 3.21 kgha-1 – 8.29 kgha-1 with the highest value 8.29kgha-1 recorded in CWU treated plots. The CWU had the highest values in bulk density (1.41 gcm-3), moisture content (28.38%) and aggregate stability (32.05%) but showed non-significant values in hydraulic conductivity (2.45 cmhr-1) and least value in mean weight diameter (0.85). The results revealed that the combination of cow dung manure and urea fertilizer could enhance cucumber growth, yield quality and soil fertility in the studied area. [4]

Climate Change Information Source and Indigenous Adaptation Strategies of Cucumber Farmers in Enugu State, Nigeria

The study assessed the climate change information source and the indigenous adaptation strategies of cucumber farmers in Enugu State. A multi-stage sampling technique was used in selecting 80 respondents. Data were elicited using structured interview  schedule and presented in percentage and mean scores. Findings showed that the majority (92.5%) of cucumber farmers never had contact with extension workers. Information on climate change was mainly from neighbours/friends and personal experience. The indigenous strategies employed for climate change adaptation were organic manure ( =2.91), crop diversification (=2.75), early harvesting ( =2.74) planting early maturing varieties ( =2.59), prompt weeding ( =2.79) among others. The major challenges encountered by the respondents included poor market facility ( =2.36),  non-availability of credit facility ( =2.74), non-availability of storage facilities ( =2.75), high cost of labour ( =2.48), poor access to information sources ( =2.30), limited income ( =2.58). It was recommended that high level awareness via media campaign be employed by government extension agency to educate  cucumber farmers on climate change issues. Also, a sustainable national climate change policy should be championed by the Ministry of Agriculture to build farmers capability to adapt to climate change. Also, government should intervene in the issues of credit, input/facilities and map out a framework to guarantee access to land by farmers for enhanced resilience and expand of production. [5]
