Three cropping systems using 5 crop species were compared over a 10-year period on a cracking clay soil (Vertisol) in the sub-humid subtropics of eastern Australia. The 3 cropping systems were continuous (the same crop every year), alternate (the same crop every second year) and double (a winter and summer crop in the one year). There were 2 cereal crops (sorghum and wheat) and 3 grain legumes (chickpea, green gram and black gram). The effect of cropping system was measured in terms of grain and protein yields and changes in soil organic carbon (surface 0-10 cm) and nitrogen concentrations. Summer and winter rainfall was below average in 8 and 5 years out of 10, respectively. Grain yield of cereal monocultures was about twice that of legume monocultures. The potential for double cropping, despite the generally below-average rainfall, was clearly shown with the highest grain and protein yields coming from the combination of green gram (summer) and wheat (winter). Averaged over 10 years, wheat yield (1460 kg/ha. year) was identical in the continuous and alternate cropping systems. Sorghum yields were marginally higher with alternate cropping (1340 kg/ha. year) than continuous cropping (1050 kg/ha. year). With double cropping, average wheat yields were 1081 and 698 kg/ha when combined with green and black gram, respectively. Black gram gave half the average yield of either green gram or chickpea (about 300 v. 600 kg/ha). This was attributed to the indeterminate nature of the crop in an environment with variable rainfall and to the detrimental effect of above-average rainfall during harvest time. Soil nitrogen and carbon levels, with initial values of 0.22 and 2.96%, were reduced at the end of 10 years by 16 and 27% respectively. Their rate of decline did not differ between cropping systems.

Planting energy sorghum to remove soil cadmium (Cd) has been selected as an effective phytoremediation method in subtropical farmland in China in recent years. Nevertheless, the effects of energy sorghum species and cropping systems on Cd removal by energy sorghum are still not fully understood. In the present work, biomass sorghum (BS) and sweet sorghum (SS) were planted for screening varieties and comparing the applicability of cropping systems to remove Cd from contaminated soils through batch field experiments. The results indicated that BS had a higher plant height (4.70–75.63%), lower water content in the shoot (4.78–13.49%), greater dry biomass yield (13.21–125.16%), and stronger Cd removal (average 45.71%) compared with SS. Significant differences (p < 0.05) were observed in the agronomic traits and Cd accumulation of energy sorghums with genetic regulation of varieties. Pearson correlation coefficients analysis and the structural equation model (SEM) showed that plant height was the crucial agronomic parameter affecting the dry biomass yield, and Cd concentration in the stem was the key factor for evaluating the Cd extraction ability of energy sorghums, which indirectly determined the removal of Cd by energy sorghum together. Furthermore, the regeneration cropping system was the most suitable because of the adaptation to climatic conditions of energy sorghums in subtropical regions of China, and its Cd removal efficiency increased by more than 49% compared with double cropping and single cropping systems, respectively. Our study provides valuable information for the phytoremediation of Cd-contaminated soil in Chinese subtropical farmland.

Globally, the majority of farmers use various cropping systems. In order to increase the production of food grains, the adaptation of these cropping systems necessitates intensive cultivation, which eventually calls for a greater quantity of macronutrients as well as micronutrients. The availability of micronutrients is greatly influenced by cropping practices, their distribution by profile and chemical pools, and their accessibility to plants. Many crops can reach beneath the soil layers and access the micronutrients with their deep roots, which they require to grow. The present study was conducted to quantify the impact of different cropping systems on DTPA extractable micronutrients viz., Zn, Fe, Cu, and Mn over time. Soil samples were collected from the surface layer (0-15 cm) of four cropping systems i.e., cereal-cereal (CC), cereal-oilseed (CO), vegetable-vegetable (VV), and fodder-fodder (FF). The micronutrient cations were found highest under the VV cropping system when compared with all four cropping systems. The results illustrate that availability of micronutrients is affected by the presence of high organic carbon content and favourable soil reaction.

This is the first study to investigate alternative fertilisation strategies to increase cereal production while reducing greenhouse gas emissions from the most common soil type in subtropical regions. The results of this research will contribute to define future farming practices to achieve global food security and mitigate climate change. The study established that introducing legumes in cropping systems is the most agronomically viable and environmentally sustainable fertilisation strategy. Importantly, this strategy can be widely adopted in subtropical regions since it is economically accessible, requires little know-how transfer and technology investment, and can be profitable in both low- and high-input cropping systems.

This thesis investigated the impact of organic sources of nutrients on greenhouse gas emissions (carbon dioxide, nitrous oxide and methane), nitrogen use efficiency and biomass production in subtropical cropping soils. The study was conducted in two main soil types in subtropical ecosystems, sandy loam soil and clay soil, with a variety of organic materials from agro-industrial residues and crop residues. It is important for recycling of agro-industrial residues and agricultural residues and the mitigation of greenhouse gas emissions and nitrogen use efficiency.

In the warm and humid tropics and subtropics, conservation agriculture, based on no-tillage and cropping systems with high biomass production, creates a positive balance between the output and input of carbon (C), which increases soil organic C (SOC) stocks by 0.3–0.6 Megagrams per hectare per year (Mg ha-1 yr-1 )in the top 30 cm and in some cases >1.0 Mg ha-1 in the top 1 m of soil. The occlusion of organic matter (OM) inside stable aggregates, facilitated by no-tillage and organo-mineral interactions, are important factors in SOC accumulation, in addition to the high biomass input by crops, such as maize, and by cover crops, including legumes. Lower nitrous oxide emission and higher methane consumption in no-tillage soils reduce the yield-scaled greenhouse gas (GHG) emission compared with conventionally tilled soils. There is potential to foster C sequestration in tropical and subtropical soils, but only when suitable soil and OM management is utilised.

The majority of strawberries produced in the world are grown in the open field, and only in the past 50 years has protected cropping become established as a commercially viable system. Soilless culture (hydroponics) is an important component of this form of intensive production because it enables the strawberry crop to be grown above the ground (table top system) which can provides an improved root environment, nutrition and irrigation and at the same time easier fruit harvesting. Solid media systems predominate over liquid based systems with peat and coir being the most popular media. Future production appears to be increasingly towards year round production by the improved control of the plant environment, combined with reducing harvesting costs by robotic harvesting.

Legumes are economically important crops for the achievement of food security status in many countries in the tropical and subtropical regions of the world. Among various environmental stresses, biotic constraints to the production of grain legumes such as cowpea and soybean are becoming increasingly significant with the recurring change in climatic patterns and diverse environmental alterations. The economic impact of biotic factors such as disease-causing pathogens (fungi, bacteria, viruses and nematodes), insect pests and parasitic weeds has become overwhelming. These biotic stressors induce a wide range of damage symptoms which include stunting, wilting of stems, defoliation, root rots and premature death of plants. Yield losses due to the activities of biotic stress factors have been very significant. Hence, it is imperative to be informed of the various biotic stressors that affect the growth and yield potential of cowpeas and soybeans in various cropping systems. This review seeks to highlight existing pests and diseases in cowpea and soybean and evaluate their impact on the growth and productivity of these crops. It is hoped that the review will further spur scientific research into how these biotic factors can be managed or even manipulated to ensure agricultural sustainability, high economic returns, and global food security.

Abstract Balancing resources against opportunities is a skill developed over generations by African smallholders. By exploiting variations in the local environment, both in time and in space, farmers and pastoralists minimize the risk of loss in an unpredictable environment. This is an indigenous alternative to more tecnologically developed systems where ecological variation is eliminated, or significantly reduced, with the aid of technology. Constantly juggling the limited resources available to them, indigenous farmers adjust to a non-equilibrial physical environment and changing social and economic circumstances by working round problems rather than by combating them directly. The case of farmers in Gambia’s Western Division is a good example. In response to protracted drought and to the loss of labour from rural-urban migration, dryland farmers adjusted their cropping patterns, growing less labour-intensive and more drought resistant crops such as cassava and tree crops, particularly fruit (see Chapter 6). Irrigation and labour-saving mechanization were never options. As the drought has continued, labour remains a problem, the cost of living has risen, the cost of education, with which most families are concerned, has escalated, and farmers have begun to specialize in the production of mangoes and more recently, cashew. These tree crops are more drought resistant than oranges and are higher in value, as long as they can be marketed. Contrary to expectations, cassava production has fallen back slightly because farmers find it difficult to successfully fence more than one, or at most two, cassava plots. Fencing is critical because cassava grows through the dry season and unless very well protected, is easy prey for animals which, in this part of the region, are not herded in the dry season. Thus adaptations to change are being made constantly but there is little evidence that such changes are being noticed either by government or by the aid agencies involved in the agricultural sector in The Gambia. This reinforces a personal view that in spite of verbal acknowledgement of the competence of smallholder producers, their skill in coping with problems receives little recognition from policy makers. Smallholders are not perceived as a resource and their potential contribution to agricultural development remains invisible to those with the power to influence change.
