Enhancing Non-symbiotic N2 Fixation in Agriculture
Much of the demand for nitrogen (N) in cereal cropping systems is met by using N fertilisers, but the cost of production is increasing and there are also environmental concerns. This has led to a growing interest in exploring other sources of N such as biological N2 fixation. Non-symbiotic N2 fixation (by free-living bacteria in soils or associated with the rhizosphere) has the potential to mee...
متن کاملAssociation of transpiration efficiency with N2 fixation of peanut under early season drought
Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...
متن کاملN-feedback Regulation of N2 Fixation in Medicago Truncatula under P-deficiency
The objective of the present study was to determine a possible interconnection between a P-deficiency induced decline in nitrogen fixation of Medicago truncatula Gaertn. (barrel medic) cv. Jemalong and the accumulation of nitrogen or amino acids in different organs of the plants as a possible agent of a N-feedback mechanism. Nodulated plants were grown in N-free nutrient solution at increasing ...
متن کاملAssociation between aflatoxin contamination and N2 fixation in peanut under drought conditions
Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...
متن کاملEvidence that P deficiency induces N feedback regulation of symbiotic N2 fixation in white clover (Trifolium repens L.).
Trifolium repens L. was grown to test the following hypotheses: when P is deficient (i) N2 fixation decreases as a result of the plant's adaptation to the low N demand, regulated by an N feedback mechanism, and (ii) the decrease in the photosynthetic capacity of the leaves does not limit N2 fixation. Severe P deficiency prevented nodulation or stopped nodule growth when the P deficiency occurre...
