Sowing and application of mineral and organic fertilizer is generally done manually in the Sahel, resulting in low precision and delayed application. The objective of this paper is to present a new mechanical planter (Gangaria) for the combined application of seeds and soil amendments (mineral fertilizer, compost, etc.), and to assess the effects of using this planter in pearl millet on labor use, yield and economic return. The labor study showed that the mechanized application of seeds and compost reduced time use by a factor of more than six. The on-station experiments were completely randomized experiments with six replications and six treatments: T0 (control), T1 (0.3 g NPK hill−1), T2 (25 g compost hill−1), T3 (25 g compost + 0.3 g NPK hill−1), T4 (50 g compost hill−1) and T5 (50 g compost + 0.3 g NPK hill−1). Treatments T1 to T5 were sown by the planter with seeds that were primed in combination with coating of seeds with a fungicide/insecticide. The treatment T5 increased grain yield and economic return compared to the control by 113% and 106%, respectively. The advantages for farmers using this approach of agricultural intensification are timelier sowing of dryland cereal crops, easy application of organic fertilizer and more precise delivery of input, thereby making this cropping system more productive and less vulnerable to drought.

Farmers in Northern Ethiopia integrate legumes in their cropping systems to improve soil fertility. However, biological nitrogen fixation (BNF) potentials of different legumes and their mineral nitrogen (N) and phosphorus (P) demands for optimum BNF and yields are less studied. This study aimed to generate the necessary knowledge to enable development of informed nutrient management recommendations, guide governmental public policy and assist farmer decision making. The experiment was conducted at farmers’ fields with four N levels, three P levels, and three replications. Nodule number and dry biomass per plant were assessed. Nitrogen difference method was used to estimate the amount of fixed N by assuming legume BNF was responsible for differences in plant N and soil mineral N measured between legume treatments and wheat. The result revealed that the highest grain yields of faba bean (2531 kg ha−1), field pea (2493 kg ha−1) and dekeko (1694 kg ha−1) were recorded with the combined application of 20 kg N ha−1 and 20 kg P ha−1. Faba bean, field pea and dekeko also fixed 97, 38 and 49 kg N ha−1, respectively, with the combined application of 20 kg N ha−1 and 20 kg P ha−1; however, lentil fixed 20 kg ha−1 with the combined application of 10 kg N ha−1 and 10 kg P ha−1. The average BNF of legumes in the average of all N and P interaction rates were 67, 23, 32 and 16 kg N ha−1 for faba bean, field pea, dekeko and lentil, respectively. Moreover, faba bean, field pea, dekeko and lentil accumulated a surplus soil N of 37, 21, 26 and 13 kg ha−1, respectively, over the wheat plot. The application of 20 kg N ha−1 and 20 kg P ha−1 levels alone and combined significantly (p < 0.05) increased the nodulation, BNF and yield of legumes; however, 46 kg N ha-1 significantly decreased BNF. This indicated that the combination of 20 kg N ha−1 and 20 kg P ha−1 levels is what mineral fertilizer demands to optimize the BNF and yield of legumes. The results of this study can lead to the development of policy and farmer guidelines, as intensification of the use of legumes supplied with starter N and P fertilizers in Northern Ethiopian cropping systems has the multiple benefits of enhancing inputs of fixed N, improving the soil N status for following crops, and becoming a sustainable option for sustainable soil fertility management practice.

Yield And Yield Components

In Malawi the demand of the use of mineral acidifying fertilizer by farmers for sustenance of high crop yields is increasing. The soaring demand is a pointer to the loss of humic substances in the soil and the resultant poor soil health. There is potential however to reduce the amount of mineral fertilizer used by the farmers and retain the applied nutrients within the plants rooting zone for increased use efficiency and productivity. This could be achieved through the combined application of humate based fertilizers with mineral fertilizer. Therefore, an experiment was conducted to evaluate the effect of different rates of NPK and humate based fertilizer (HBF) combinations on potato yield and yield components at Tsangano, Bembeke and Dwale Extension Planning Area (EPA) in the 2016/2017 cropping season. Ten treatments were laid out in a randomized complete block design (RCBD). Baseline soil data were collected and subjected to standard laboratory analytical procedure. Agronomic data collected in the experiment were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance (ANOVA) at 95% level of confidence. The means were separated by the least significant difference (LSD0.05). Laboratory analysis showed that soils were strongly acid at the three sites with low amount of N, P, K except for Dwale EPA which had high P and medium content of K. Furthermore, results showed that different NPK and HBF combination significantly influenced potato tuber yield and yield components at the three sites. The recommended fertilizer rate of NPK 8:18:15 + 6S at 250 kg ha-1 + 60 kg N ha-1 produced the highest tuber yield at Tsangano (20,729 kg ha-1) and Bembeke (5,189 kg ha-1). At Dwale EPA, application of NPK 8:18:15 + 6S at 250 kg ha-1 produced the highest yield (13,956 kg ha-1). Nevertheless, different combinations of NPK and HBF fertilizer (Treatments 7, 8, 9 and 10) also gave comparably high yields and high number of big tubers. Therefore, the combined application of mineral fertilizer and humate based fertilizer potentially could increase potato yield in Malawi, sustainably. More studies however are required in order to confirm the results.

A comparative analysis of the seeds ash composition of the breed Rif (Brassica napus L.) rapeseeds grown in the Lipetskaya region was held. The plants were grown in the conditions of the agroecological experiment using mineral (NPK and zeolite) and organic (hen droppings) fertilizers. 6 variants of the experiment were studied – the plants are grown without fertilizers application (the control); the mineral fertilizer (N60:P60:K60) separately and together with zeolite (5 t.ha-1); the zeolite in pure form (5 t.ha-1); hen droppings (5 t.ha-1) separately and together with zeolite (5 t.ha-1). We studied the accumulation of 9 basic elements (in mass %) contained in Brassica napus. seeds ash using the method of energy-dispersive X-ray spectroscopy. The accumulation order of the elements was determined: P ≈ K > Mg ≥ Ca > Mo > S > Zn > Mn > Fe. The proportion of P fluctuated from 10.852 to 11.855 mass %; the proportion of K – from 9.933 till 12.343 mass %. The rapeseeds contained Mg, Ca, and Mo in similar concentrations within the range of 4.0 -5.8 mass %. The combined application of zeolite with organic fertilizer ensured the accumulation of the minerals in the seeds. Correlations between the elements were established. High correlation between elements K and Mo was found (r = 0.96); P and Mg (0.86); P and Fe (r = 0.94); C and Mo (r = 0.86). The positive effect of the combined organic-mineral fertilizers with poultry farms wastes usage on the mineral elements accumulation in rapeseeds was stated. It is noted that the accumulation of P, Ca, Mo, and S in rape seeds leads to a decrease in Zn.

Application of organic fertilizers in improving soil fertility has become a major factor that has enabled the world to feed billions of people. However, the required quantities of organic material are enormous, so it becomes necessary to combine different types of fertilizers to feed plants. The effectiveness of human feces compost (HC) alone, as well as in combination with single super phosphate (SSP), was evaluated in the present study. A field experiment was conducted at farmer field located in district Swabi (Pakistan). A total of eight possible treatments combination were arranged in randomized complete block design (RCBD), replicated four times. Two levels of human feces compost (HC), including control (HC0: control and HC1: 7.5 t ha-1) and four levels of P, as single superphosphate (SSP), including control (P0: control, P1:40 kg ha-1, P2: 60 kg ha-1 and P3: 90 kg ha-1) were utilized in the experiment. Results revealed that among all the treatments, combined application of SSP at 60 kg ha-1 along with 7.5t ha-1 HC significantly improved the growth, as well as the yield parameters of wheat crop. These results allow saving a half of usually made mineral fertilizer dose for the cultivation of wheat crop. Combined use of HC and SSP were strongly recommended for obtaining maximum wheat yield in the prevailing soil and environmental conditions.

Terminal Drought Stress

Wheat is an important global staple food crop; however, its productivity is severely hampered by changing climate. Erratic rain patterns cause terminal drought stress, which affect reproductive development and crop yield. This study investigates the potential and zinc (Zn) and silicon (Si) to ameliorate terminal drought stress in wheat and associated mechanisms. Two different drought stress levels, i.e., control [80% water holding capacity (WHC) was maintained] and terminal drought stress (40% WHC maintained from BBCH growth stage 49 to 83) combined with five foliar-applied Zn-Si combinations (i.e., control, water spray, 4 mM Zn, 40 mM Si, 4 mM Zn + 40 mM Si applied 7 days after the initiation of drought stress). Results revealed that application of Zn and Si improved chlorophyll and relative water contents under well-watered conditions and terminal drought stress. Foliar application of Si and Zn had significant effect on antioxidant defense mechanism, proline and soluble protein, which showed that application of Si and Zn ameliorated the effects of terminal drought stress mainly by regulating antioxidant defense mechanism, and production of proline and soluble proteins. Combined application of Zn and Si resulted in the highest improvement in growth and antioxidant defense. The application of Zn and Si improved yield and related traits, both under well-watered conditions and terminal drought stress. The highest yield and related traits were recorded for combined application of Zn and Si. For grain and biological yield differences among sole and combined Zn-Si application were statistically non-significant (p>0.05). In conclusion, combined application of Zn-Si ameliorated the adverse effects of terminal drought stress by improving yield through regulating antioxidant mechanism and production of proline and soluble proteins. Results provide valuable insights for further cross talk between Zn-Si regulatory pathways to enhance grain biofortification.
