<div>Background: Fertilizer application combined with successive foliage cuttings can positively affect plant growth, yield and quality. The objective of this study was to evaluate the response of chipil&iacute;n to successive foliage cuttings and nitrogen and phosphate fertilizer application under greenhouse conditions.&nbsp; 
 
Methods: During 2018, an experiment was carried out in a greenhouse under a completely randomized design, with six replications of each treatment. The treatments were as follows: control, 100 kg ha-1 N as urea and 60 kg ha-1 P2O5 as triple superphosphate. The fertilizers were applied one month after planting (MAP). Two MAPs, uniform cuttings were performed, followed by three successive cuttings, with one every 30 days. At each cutting, the traits evaluated included the number of new shoots; the length, diameter, leaf area and dry biomass of the new shoots by component (leaves and stems); the relative growth rate (RGR) of the biomass of the shoot leaves, the chlorophyll (a, b and total) and carotenoid content and NDVI.&nbsp; 
 
Result: Cutting foliage every 30 days increased (p&lt;0.05) the number of new shoots, leaf biomass, total biomass and leaf area, but reduced the length and diameter of the shoots. There was no effect (p&gt; 0.05) of cutting on root biomass or nodulation, but there was an effect of fertilizer application, with both variables decreasing with nitrogen addition.</div>

Background: Aluminium (Al) stress is among the prime limitations of crop production including Lentil, in acidic soils as Al solubilizes into phytotoxic forms at low pH causing root growth inhibition, minimizing plant-vigor and yield. The current study was performed to identify the Al tolerant RILs based on root-regrowth studies, short term growth culture and organic acid exudation in reaction to Al toxicity under hydroponics.&nbsp; 
 
Methods: The study involved screening for Al toxicity tolerance in recombinant inbred lines (RILs) population of lentil through root re-growth studies, short term growth response method under hydroponics treated with toxic concentration of Al (148 &micro;M), organic acid exudation using HPLC and correlation analysis among the traits.&nbsp; 
 
Result: ANOVA for root and shoot traits revealed presence of highly significant genotypic differences for all the traits. High GCV along with high H2bs and GA% were observed for the traits revealing the influence of additive genes and suggested reliable selection of these traits for Al toxicity tolerance. Citric acid was exudated in highest amount in all the genotypes and was positively and significantly correlated with RRG. Based on the hydroponics study and organic acid exudation, RILs identified as tolerant were LRIL-10, LRIL-37, LRIL-68, LRIL-96, LRIL-97, LRIL-113, LRIL-125, LRIL-133, LRIL-143, LRIL-144 and LRIL-148. With further evaluation, these RILs may serve as important Al toxicity tolerant varieties suitable for acidic soil conditions. Also, these lines may serve as donors of Al toxicity loci and mapping of Al tolerance genes.
