“…Therefore, leaves with better length and width have more leaf area and subsequently LAI. Similarly, the better leaf area ensures the better light harvesting which resulted in production of more assimilates and subsequent CGR (Muhsin et al, 2021;Aslam et al, 2021). The current results also coincide with the outcomes of Aslam et al (2003) and Sattar et al (2010) they noted that use of 150 kg/ha seed rate provided the greatest value of leaf area index and CGR.…”

“…There is a big gap among potential and actual yields of wheat crop and this large gap is due to a lack of knowledge about agronomic management and certain factors including late sowing of wheat, non-availability of high-quality certified seeds, poor plant geometry. poor fertilization, improper irrigation technique and high weeds infestation, seed rate and seed size (Sattar et al, 2010;Zain et al, 2017;Hassan et al, 2020a, b;Muhsin et al, 2021;Aslam et al, 2021).…”

| Optimum seeding density and seed size are imperious agronomic practices for improving wheat productivity. Therefore, this field study assessed the impact of diverse seeding rates and seed sizes on performance of wheat. The study was comprised of various seeding rates 100, 125 and 150 kg ha -1 and different seed sizes i.e., bold seed (more than 2.7 mm), medium seed (less than 2.7 mm) and small seed (less than 2.3 mm). The various seed sizes and rates significantly affected performance of wheat crop. For seed sizes maximum LAI, CGR, plant height (94.32 cm) productive tillers (PT) (364 m -2 ), thousand grain weight (TGW) (42.67 g), biological yield (BY) (10.61 t ha -1 ), grain yield (GY) (4.49 t ha -1 ) and harvest index (HI) (41.94%) was obtained with 150 kg ha -1 seeding rate and lowest LAI, CGR, height (88.65 cm) PT (283.11 m -2 ), TGW (38.30 g), BY (9.57 t ha -1 ), GY (3.66 t ha -1 ) and HI (38.66) was noted in seed rate of 100 kg ha -1 . In case of seed size maximum LAI, CGR, plant height (99.67 cm), PT (348 m -2 ), TGW (42.67 g), BY (10.68 t ha -1 ), GY (4.53 t ha -1 ) and HI (42.68%) was recorded with bold seed (more than 2.7 mm) LAI, CGR, plant height (88.09 cm) PT (294 m -2 ), TGW (36.29 g), BY (9.62 t ha -1 ), GY (3.61 t ha -1 ) and HI (36.92%) was recorded with small seed size (less than 2.3 mm). In conclusion, 150 kg ha -1 of seed rate and bold seed size can be used under Faisalabad conditions to get the maximum wheat production.

“…A pesar de la creciente evidencia sobre el aumento de la eficiencia del uso del nitrógeno, a través del manejo del cultivo, como el momento y cantidad correcta de aplicación del fertilizante (Olson and Swallow, 1984, Wuest and Cassman, 1992, Morais, 1998, Romero-Lozada et al, 2016, Rosas-Patiño et al, 2017, pocas investigaciones se han realizado para examinar si la fuente nitrogenada mineral puede mejorar el rendimiento y calidad de los cultivos, así como mejorar los ingresos de los productores y mitigar la contaminación ambiental, especialmente en ecosistemas amazónicos. Algunos trabajos indican que existe influencia significativa en el crecimiento y producción de acuerdo a la fuente nitrogenada aplicada a los cultivos de maíz, papa, arroz, trigo, verdolaga entre otros (DeAndrade, et al, 2009, Kaymak, 2013, Pineda-Taco et al, 2020, Yan et al, 2020, Alsam et al, 2021. Granja and Covarrubias (2018), reportan disminuciones de pH a nivel del suelo e incremento de clorofila en aguacate cultivado en suelos calcáreos al aplicar sulfato de amonio en comparación con urea y nitrato de calcio.…”

Background. In the new global economy, cocoa is an important crop. However, far too little attention has been paid to the nutritional aspects. On the other hand, nitrogen is the most important nutrient in crop production, and mineral nitrogen fertilizers are the most widely used by farmers. Improving the efficiency of nitrogen uptake and utilization could potentially increase crop yields and quality, as well as reduce nitrogen fertilization and environmental pollution. Objective. Therefore, the objective of this study was to evaluate the effect of three nitrogen sources on morphological characteristics, yield and quality of CCN-51 cocoa, and soil chemical characteristics in the Ecuadorian Amazon. Methodology. A randomized design was established with 4 treatments with the same N dose, but varying the source (amide: urea, calcium nitrate, NC, and ammonium sulfate, SA), plus a control without N application. The investigated variables are soil chemical characteristics, shoot growth, fruit morphology, seed chemical characteristics, production and yield estimates, and agronomic efficiency of the sources. Results. NC maintained soil pH at 5.29 points compared to SA and urea, which acidified at a higher rate (4.32 and 3.96), leading to an increase of N and a decrease Ca in the soil. SA increased the fat content in the cocoa seed (54.1 %), with a higher number of fruits per plant (16.7) and, therefore, a better yield (0.799 t/ha). Implications. These results provide basic information on the nitrogen source effects and cocoa nutrition to be considered for future research. Conclusion. The findings suggested that NC conserves soil pH better than the other sources. SA increases production and fat content, so it can be considered the most efficient.

Agricultural Waste - New Insights

Increasing demand of agricultural production for human, animal, and industrial requirements is responsible for the enhancement of agricultural and agro-industrial activities. Each step of such activities produces various types of agricultural waste that include crop residue, on-farm livestock and fisheries waste, forest waste, agro-industrial waste, etc. Currently, handling and managing agricultural waste is a challenging task worldwide, especially in the context of environmental pollution control and sustainable agriculture. Thus, efficient management in terms of reuse, recycling, and reduction of agricultural waste is needed not only for the sustainable agriculture but also for farmers’ profitability. Various type of farm machinery is available and are in use to collect the crop residue from the field or directly incorporate the residue into the soil. The incorporated crop residue not only increases the soil fertility but also decreases the greenhouse gases emission due to burning of the crop residue. The crop residue chopper can be a solution of residue management at farmer field level. This chapter provides a review on the crop residue collection handing and incorporation machinery performance and their advancement.
