Potato (Solanum tuberosum L.) is one of the most important tuber crops produced in Pakistan. Due to its nutritive importance, it ranks as fourth after rice, wheat and maize in the world. However, production of the crop is far below the average due to poor crop stand, soil fertility and water management practices. There is a strong need for improvement in the fair yield of potato through managed production techniques and best soil nutrient combinations. To find out the best combination of fertilizer level of NPK on growth, yield and quality of the potato crop, nine field experiments on potato crop were conducted at Rawalpindi division, Punjab Pakistan for three successive Rabi seasons during 2014-2017. Treatments consisted of four levels of N (244, 300, 356 and 412 Kg N ha-1), P (163, 200, 237 and 275 kg P ha-1) and K (136, 167, 198 and 229 Kg K ha-1) laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that there was no significant difference of location in terms of yield (T ha-1). However, mean data showed that the fertilizer combinations significantly (<0.05) affected yield and yield components of the potato crop. Among the treatments, NPK level (412, 275 and 229 Kg ha-1) gave maximum (100 tuber m-2), potato yield (3.2 Kg m-2), dry matter (1.3 Kg m-2), while the least number of tuber m-2 (63), potato yield m-2 (2.02 Kg), dry matter yield m-2 (0.9 Kg) were recorded where combination NPK (244, 163and 136 Kg ha-1) were applied. From the results, it can be concluded that farming community can obtain the maximum potato yield by adopting NPK (412, 275, 229) levels of fertilizers

Field experiments were conducted during the 2015 and 2016 cropping seasons at the Teaching and Research (T & R) Farm of the College of Agriculture, Kwara State University, Malete, to determine the effect of cropping patterns on weed infestation, growth and yield of a maize/soybean intercrop in the southern Guinea savanna of Nigeria. The experiments consisted of six treatments as follows: one row of maize alternated with one row of soybean (1:1), one row of maize alternated with two rows of soybean (1:2), two rows of maize alternated with one row of soybean (2:1), two rows of maize alternated with two rows of soybean (2:2), sole maize (1:0) and sole soybean (0:1). The treatments were laid out in a randomized complete block design with three replicates. Data collected were subjected to analysis of variance and means were separated by the least significant difference (LSD) at the 5% level of probability. Results showed that sole soybean consistently suppressed weeds and resulted in a higher yield. Similarly, the 2:1 ratio of maize to soybean did not only reduce weed density, it produced significantly higher yields of maize and lower yield of soybean, and had the higher land equivalent ratio and economic returns followed by sole maize.

Nitrogen fertilization has considerable effects on growth and yield of potato crop. Leaf expansion is one of the most important growth parameters that can be used to optimize nitrogen fertilization management in agroecological practices. We evaluated the effect of nitrogen fertilization on the leaf area index (LAI) of potato crop during different phenological stages by two different methods. Experimental plots were established in a randomized block design with the following treatments: no nitrogen supply (0-N), 133 kg N ha-1 (133-N), and 400 kg N ha-1 (400-N), using the Granola variety, at the Andes region, Merida city, Venezuela. We measured leaf area at the main phenological stages of the crop using a plant canopy analyzer. LAI showed significant differences among treatments and phenological stages, except during the emergence stage. The maximum LAI values were obtained 55 days after emergence: 400-N (1.42±0.16) > 133-N (0.92±0.21) > 0-N (0.34±0.08). Nitrogen fertilization had a significant effect on the development of LAI in potato crop along its different phenological stages.

Field experiments were conducted at the Agricultural Engineering Experimental Farm of The Federal University of Technology, Akure, during 2006/2007 and 2007/2008 seasons to investigate the response of cassava under drip irrigation. The experiment was laid out in a randomised complete block design (RCBD) with three replications. The treatments were based on four different water regimes; with T100 receiving 100% available water (AW), T<sub>50</sub> and T<sub>25</sub> receiving 50% and 25% of AW and T<sub>0</sub> with zero irrigation (control treatment). Disease free stems of the cassava cultivar TMS 91934 were planted at a spacing of 1 m by 1 m. The results indicated that T<sub>100</sub> full treatment produced the highest average total dry matter yield of 49.12 and 37.62 t/ha in 2006/07 and 2007/08 cropping seasons, respectively. However, the average total dry matter production in T<sub>50</sub>, T<sub>25</sub>, and T<sub>0</sub> showed significant differences in their values. Low total dry matter yields of 7.12 and 5.92 t/ha, respectively, were associated with T<sub>0</sub> for the two cropping seasons. The total water use of 1491.75 and 1701.13 mm was recorded for T<sub>100</sub>, while total water use of 729.00 and 651.13 mm were obtained for T<sub>0</sub> in the two cropping seasons. The water use efficiency determined for the two cropping seasons ranged between 7.38 kg/ha and 32.93 kg/ha. The percentages of total water applied from total water use for T<sub>100</sub> were 51.11% and 61.72%, while 14.83% and 17.85% were recorded for T<sub>25 </sub>for 2006/07 and 2007/08 cropping seasons, respectively.

The decline in rice yields as a result of excessive chemical fertilizer (CF) inputs is a matter of great concern in rice-growing regions of Asia. In two-year’s field experiments, the nitrogen, phosphorus, and potassium (NPK) status, growth characteristics and yield of rice were examined by application of poultry manure (PM), cow manure (CM) and compost (CP). Organic fertilizers were applied as EMN (estimated mineralizable N) based on their total N content. Six treatments were assigned in a randomized complete block design: (1) no-N fertilizer (N0); (2) 50% CF (CF50), (3) 100% CF (CF100); 50% CF + 50% EMN from (4) PM or (5) CM or (6) CP. Compared with CF100, the CF50PM50 (total N ≥ 4%) accumulated higher N, P and K content in leaf, sheath, panicle and seeds, resulting in greater growth and yield. The CF50PM50 increased yield by 8.69% and 9.70%, dry matter by 4.76% and 5.27% over CF100 in both years. The continuous application of CF50CM50 (total N < 4%) and CF50CP50 (total N < 4%) treatments led to similar NPK contents but higher yields than those of CF100 treatment in 2018. In conclusion, the organic fertilizer (total N ≥ 4%) with the EMN method enhances higher N availability in each year. Continuous application of organic fertilizer (total N < 4%) over two years effectively increased N availability in the second year. The 50% organic fertilizer (total N ≥ 4%) and 50% CF led to increased NPK availability and rice yields over the 100% CF treatment, reducing CF usage and leading for sustainable agriculture.

: The field experiment was performed during the autumn growing season 2019 in Al Khyoot village of the Qurna town which is located at 75 km northern Basrah city centre. For improving the maize growth and yield, the effect of foliar spraying with iron and zinc and the most important technological characteristics of the knapsack sprayer such as nozzle types was studied. Three nozzle types were investigated as standard Flat fan nozzle, Hollow cone nozzle, and Tip nozzle (as reference nozzle in this study). Three foliar concentrations (0, Zn30 + Fe100 and Fe100+ Zn30) as well as a 16- litre capacity of the knapsack sprayer were used for fertilizer spraying experiments. All field experiments were carried out using the complete randomized block design (RCBD) with three replications. The results of the statistical analysis showed that there was a significant effect of the nozzle type and foliar spraying on the plant growth and yield characteristics as plant height, stem diameter, number of leaves, leaf area, number of grains, and yields (152.39 cm, 1.88 cm, 13.98, 4559 cm2, 376.51 and 5.51 Mg ha-1 respectively). Also, these characteristics showed an increase percentage as following (2.79%, 2.25%, 0.60%, 3.11%, 3.70%, and 1.73% respectively) when the hollow cone nozzle was used compared to the reference nozzle. In addition, an interaction between the studied factors also appeared a significant difference in the grain number and yield characteristics.

A case study in Indonesia of circular bioeconomy implementation was investigated by managing livestock wastes, especially goat manure (GM), which an excess of its availability may be adverse to the environment. The efficacy of this scenario to control pollution or to increase productivity still needs to be proven. Hence, this research aimed to study the possibility of circular bioeconomy implementation using biotic and abiotic resources in Indonesia under excessive nutrients (GM and mycorrhizal) on P. angulata production. Outdoor factorial container experiment was carried out using a randomized complete block design in Central Java, Indonesia. Treatments included four levels of GM (0, 10, 20, 30 g plant−1) and four levels of mycorrhizal (0, 10, 20, 30 g plant−1) applied in the soil with six replications. This case study revealed that the use of mycorrhizal inoculant and GM indicated no significant difference to most of P. angulata’s growth and yield parameters. The implementation of circular bioeconomy through integrated farming of P. angulata was not an instant solution for economic and environmental optimization, but can be considered as a way to tackle environmental problem due to the excessive livestock wastes. The environmental sustainability can be achieved step by step, without hindering farmers’ income.
