Abstract:

A field experiment was conducted at RARS Nandyal during Kharif season of 2017 to study the precision nitrogen management in rice crop, grown under conservation agriculture. The experiment was laid out in a randomized block design with seven treatments (absolute control, recommended dose of fertilizers (100% RDF), STBF, precision N management practices like green seeker, LCC, SPAD) in vertisols. Amongst tested N management strategies; a saving of N by 45 and 20 kg with green seeker, LCC and SPAD, respectively was found compared to recommended dose of fertilizers (RDF).

Abstract:

Precision agriculture technologies have developed optical sensors which can determine plant’s normalized difference vegetation index (NDVI).To evaluate the relationship between maize grain yield and early season NDVI readings, an experiment was conducted at farm land of National Maize Research Program, Rampur, Chitwan during winter season of 2012. Eight different levels of N 0, 30, 60, 90, 120, 150, 180 and 210 kg N/ha were applied for hybrid maize RML 32 × RML 17 to study grain yield response and NDVI measurement. Periodic NDVI was measured at 10 days interval from 55 days after sowing (DAS)

Abstract:

Enhancing sustainability in modern farming systems, it is crucial to minimize environmental pollution from nitrogenous fertilizers by optimizing their application rates. The cost of production for wheat is increasing in Pakistan due to irrational use of nitrogen fertilizers by farming community which are costly and sometimes lead to high vegetative growth causing severe lodging thereby reducing yield. Optimum use of nitrogen (N) fertilizer is therefore empirical to improve the productivity of wheat at a reasonable cost. A field study for two-year was conducted at Ayub Agricultural Research Ins

Wheat nitrogen-use efficiency in the Yaqui Valley has been estimated at about 0·31. The nitrogen that is not recovered by the crop has important environmental costs that have regional and global consequences. In addition, these nitrogen losses represent an important reduction in farm income. The objective of the present work was to validate a technology that includes the use of N-rich strips together with the GreenSeeker™ sensor and a crop algorithm in farmers' fields with the ultimate goal of improving nitrogen-use efficiency through site-specific nitrogen management in irrigated spring wheat
