A field experiment was conducted to investigate the effect of pruned materials of two hedgerow species on wheat production and soil nutrient changes at different nitrogen levels in the research farm of the Bangabandhu Shiekh Mujibur Rahman Agricultural University (BSMARU) during November 2012 to March 2013. The design of the experiment was split plot, where two multipurpose tree species (MPTS) namely Gliricidia sepium and Leucaena leucocephala were arranged in main plots and five different doses of nitrogen (0, 25, 50, 75 and 100 % of recommended dose) with pruned materials were distributed to sub plots. Alley widths of both tree species were 6.0 meter. There were also control plots where full dose of recommended nitrogen was applied but no pruned material (PM) was incorporated. The soil chemical properties in the alleys consisting of G. sepium and L. leucocephala responded differently. Positive changes in the soil fertility in terms of soil pH, organic C, total N, available P, available S and exchangeable Ca, Mg, K and CEC of the top soil layer were observed in alley cropping system. Pruned materials application substantially reduced the nitrogen requirement for wheat production and 50 % Nitrogen fertilizer could be saved through pruned materials application. Among the tree species G. sepium seemed to be superior over L. leucocephala in building soil health.

Collection Data

This study was conducted in Eltemada, Boli and Umghoghai villages at Babanosa area in El-salam locality, South Kordofan State during 2012 and 2013. The objectives were to (1) identify and assess the most important agroforestry systems, (2) to investigate the main factors that affecting the sustainability of the systems, (3) to determine the important field crops that cultivated with trees and (4) to evaluate the effect of the agroforestry systems on the yield of the traditional field crops. For accomplishment of these study 80 questioners was designed and distributed in the selected villages. After the data collection data was analyzed by using descriptive statistic. The results showed that the most important agroforestry systems in the study area are parkland cropping system (58%), boundary planting (26%), wind-breaks (13%) and alley cropping (3%).The most important forest trees in the study area are Acacia senegal (32%), Ziziphus spina- christia (28%), Balanites aegeyptiaca (26%), Sclerocary birrea and Guera senegalensis (3%). The main field crops in the study area are groundnut (44%), sorghum (35%) and roselle (21%). The results showed that yield of groundnut and sorghum is higher under agroforestry systems compared with the mono-cropping system. The results showed that the majority of respondents (70%) prefer to cultivate field crops in agroforestry system, while (30%) prefer to cultivate the field crops in a mono-cropping system. The cultivation methods used in the study area include shifting cultivation (52%), mono-cropping (36%) and intercropping (12%).The majority of respondents (94%) showed that trees improve soil fertility in their farm land. The benefits from trees in farm land include improvement of soil properties (36%), protecting the farm land from wind erosion (28%), improvement of micro-climate (24%) and source of income which was indicated by (12%) of the respondents. The study recommended that modern agroforestry system such as improved fallow system and alley cropping should be introduced in the study area and multi-purpose trees such as Acacia senegal, Fedherbia albida and Sclerocarya birrea that improve soil fertility and diversify farmers income should be maintained.

De nos jours, la carence en fertilité des sols est un problème très répandu dans la plupart des pays subsahariens. G. sepium a été testé en association avec le cotonnier, le maïs et le sorgho afin de développer les meilleures pratiques dans deux stations de recherche et en milieu paysan dans les zones soudaniennes et soudano-guinéenne du Mali. L'objectif de cette étude était de développer, avec les producteurs participants, une technologie agro-forestière basée sur le Gliricidia sepium dans le système de culture en couloir. Le dispositif expérimental utilisé a été le Split plot à quatre répétitions. Le pH, le carbone organique du sol et l'azote ont été analysé dans des échantillons de sol de 0 à 20 cm de profondeur prélevés en 2016 au début de l'expérience et en 2018. Les rendements grains moyens de coton, de maïs et de sorgho associés au G. sepium étaient respectivement de 812, 1457 et 1377 kg.ha-1, alors qu'ils étaient significativement plus faibles sans G. sepium, avec 623, 1014 et 807 kg.ha-1 respectivement. Pendant la troisième année suivant la plantation de G. sepium, la teneur en carbone organique et en azote total du sol a augmenté de 5% dans les sols situés entre les allées. Le G. sepium en association avec les cultures a le potentiel d'améliorer leurs rendements et le sol.Mots clés : Carbone organique, azote, rendements, zones soudanienne et soudano-guinéenne, Mali English Title: Evaluation of Gliricidia sepium (Jacq.) Kunth ex. Walp effect on soil fertility, yields of cotton, maize and sorghum Nowdays, soil fertility deficiency is a widespread issue in most Sub-Saharian countries specially where the application of less input is the common agricultural practices. Thus the legume plant, G. sepium was established with cotton, maize and sorghum to develop best practices for increasing crop yield and soil fertility at two research stations and farming environment in the Sudanian and Sudano-Guinean zones of Mali. The objective of this study was to develop an agroforestry technology with farmers based on Gliricidia sepium in alley cropping system. The experimental design was Split plot with four replications. Soil pH, soil organic carbon and nitrogen were analyzed from 0-20 cm deep soil samples taken in 2016 at the beginning of the experiment and in 2018. Mean grain yields of cotton, maize and sorghum associated with G. sepium were 812, 1457 and 1377 kg.ha-1, respectively, while they were significantly lower without G. sepium with 623, 1014 and 807 kg.ha-1 as respectively cotton, maize and sorghum yield. In the third year after planting G. sepium, the soil organic carbon and total nitrogen content increased by 5% between the alleys. G. sepium in association with crops has the potential to improve crop yields and soil fertility.Keywords: Gliricidia sepium, organic carbon, nitrogen, yields, Mali.

Term Trial

SUMMARYA long-term trial with Leucaena leucocephala was initiated in 1982 to test the sustainability of Leucaena-based alley farming compared to a conventional cropping system without trees and with continuous cultivation of maize. It assessed the integration of short grazed fallows in rotation within Leucaena alleys and their effect on soil fertility and crop yields.The various treatments had no effect on soil pH during the four-year period of the trial. The organic carbon and total nitrogen contents of the soils under conventional cropping were lower by the end of the fourth year than those under alley cropping and alley grazing treatments, whereas soil phosphorus levels were lower in the alley cropping and grazing plots. Foliage dry matter production of Leucaena under alley cropping management ranged from 6.0 to 6.7 t ha−1 a−1 under continuous cropping and reached 8 t ha−1 when alley cropping was preceded by a grazed fallow. Crop yields were consistently higher with alley cropping than with conventional cropping. Alley cropping plots in rotation with two year grazed fallows gave significantly higher crop yields during cropping years than those under continuous cultivation.

The Relationship

Soil fertility determines a plant's development process that guarantees food sufficiency and the security of lives and properties through bumper harvests. The fertility of soil varies according to regions, thereby determining the type of crops to be planted. However, there is no repository or any source of information about the fertility of the soil in any region in Nigeria especially the Northwest of the country. The only available information is soil samples with their attributes which gives little or no information to the average farmer. This has affected crop yield in all the regions, more particularly the Northwest region, thus resulting in lower food production.  Therefore, this study is aimed at classifying soil data based on their fertility in the Northwest region of Nigeria using R programming. Data were obtained from the department of soil science from Ahmadu Bello University, Zaria. The data contain 400 soil samples containing 13 attributes. The relationship between soil attributes was observed based on the data. K-means clustering algorithm was employed in analyzing soil fertility clusters. Four clusters were identified with cluster 1 having the highest fertility, followed by 2 and the fertility decreases with an increasing number of clusters. The identification of the most fertile clusters will guide farmers on where best to concentrate on when planting their crops in order to improve productivity and crop yield.

In OOO “Dubovitskoe” which was organized in 2006 as investment project of the AO “Shchelkovo Agrokhim” for 2010 – 2012 three advanced crop rotations have been developed. Before their introduction the grain crops fraction in the cropping system was 62%, then it fell to 49%. At the same time the portion of raw crops increased from 15 to 20%, legumes from 6 to 8%, others (buckwheat, grain maize, etc.) - up to 23%. As of 2017, the crops of leguminous crops have increased noteworthily. There are two predominant soil types here heavy clay loam podzolized chernozem (6615 ha) and grey forest soil (856 ha). Weighted average indicators (as of 2017): humus content in the soils of arable land is 5, 34%; acidity pH is 4.92; labile phosphorus - 111.8 mg / kg soil; exchange potassium - 144 mg / kg soil. The coefficient of the soil fertility in the enterprise (weighted average) is 0.66. This means that maintaining and increasing the soil fertility for arable land of the enterprise is critical task. As a result of the research, it has been established that the technologies introduced in the crop vegetation management (CVS) in the crop rotation conditions ensure high productivity of cultivated crops and stability of humus content in soils as an energy basis and a guarantor of increasing fertility. The indicators of the labile phosphorus Р205 and exchange potassium К20 in the soils depending on the crop rotation vary from a certain decrease to expressed steady growth. Therefore it is necessary to specify seeding rates based on actual data. Sustainable soil acidification in the crop rotations under crop cultivation in OOO “Dubovitskoe” it is the result of the acid feterlizers high rates application, during studying period did not carried out required agromelioration with calcium contenting elements.
