Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...

Nitrogen (N) is an essential and often limiting nutrient to plant growth. Maize grain yields are highly responsive to supplemental N, leading to annual application of an estimated 10 million metric tons of N fertilizer to the maize crop worldwide (FAO 2004). Nearly all cultivated maize in developed countries receives some form of N fertilizer and N use is increasing in developing countries, whe...

limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

Abstract Over application of nitrogen (N) fertilizers to crops ultimately causes N pollution in the ecosphere. Studying response plant growth and uptake low-N stress may aid elucidating mechanism low tolerance plants developing crop cultivars with high use efficiency (NUE). In this study, a high-NUE mutant line A9-29 wild-type barley cultivar Hua30 were subjected hydroponic culture supply, dry ...

Lettuce (Lactuca sativa L.) efficient use of nitrogen (NUE) determines its growth and yield. We assessed the interaction effect N fertilizer biochar different particle sizes rates on NUE, yield lettuce. A factorial design arranged in Randomized Complete Block Design with four replications was used to conduct a field experiment at FRNR farm, Kwame Nkrumah University Science Technology, Ghana. Th...

The low nitrogen utilization efficiency (NUE) of commercial fertilizers is one the main hurdles in higher crop production and reduction fertilizer N losses to environment. However, interactions between most macronutrients could have synergistic outcomes that affect NUE. coating urea with biopolymers may control release synergistically impact its In this study, was coated 3% different polymers, ...

In wheat production, improving resource utilization and grain yield is the goal researcher have been pursuing. This study aimed to investigate if a regulated nitrogen (N) selenium (Se) fertilizer management could increase N use efficiency (NUE). reports effects of three application levels (N0: 0 kg ha−1, N1: 180 N2: 270 ha−1) combination Se (Se0: g Se1: 450 Se2: 900 on metabolism, NUE in 2020–2...

Low soil nitrogen (Low N) is one of the major abiotic stresses causing maize yield reduction in tropics Africa. However, genetic variation observed under low N and crossing among adaptive/NUE elite lines should be targeted for different secondary traits, economic disease inheritance studies breeding maize. In addition, drought have common traits indicating that adaptive mechanism thus, appear t...
