to study the effect of different levels of hydrogel, farm yard manure (FYM) and mulching on chlorophyll a, chlorophyll b, total chlorophyll content and chlorophyll stability index of groundnut under rainfed condition. The experiment was laid out in a Randomized Complete Block Design (RCBD) with ten treatments replicated thrice. The results revealed that, treatment with application of recommended dose of fertilizers (RDF) along with hydrogel @ 4 kg ha -1 and FYM @ 10 t ha -1 recorded significantly higher Chlorophyll 'a', Chlorophyll 'b', total chlorophyll content (before and after boiling) and higher chlorophyll stability index at different growth stages. However, significantly lower CSI was noticed in the treatment with application of RDF alone.

“…The overall average values for the proline content in the current study was higher than the values reported earlier by Anantharaju and Muthiah (2008) who reported the proline content in the ranges of 0.97 to 1.89 mg g -1 (dry weight) in ten cowpea genotypes in India. Moreover, similar result was reported in groundnut genotypes (Shinde et al, 2018).…”

The genetic potential for drought tolerance in cowpea within the small holder sector has not been fully exploited in South Africa. Thus, a drought evaluation experiment was conducted at the ARC-VOP to evaluate 28 cowpea germplasm accessions including two controls viz. IT96D-602 (drought tolerant) and TVU7778 (susceptible to drought) in the drought screening house using plastic box evaluation method in January, 2017. Genotypes raised for three weeks were subjected to 5 weeks of water stress treatment to determine their physiological response through leaf wilting index, relative water content and proline content followed by re-watering to determine genotype (s) with ability to recover from drought stress. Analyses of variance showed highly significant differences in response to moisture stress among the cowpea accessions for the selected physiological traits except for leaf wilting index at week two of drought stress. Stem greenness and recovery appeared to be a reliable indicator of drought tolerant genotypes which was readily observed in Acc1257, Acc1168, Acc2355, IT96D-602 and Acc5352 which also correlated significantly and positively with relative water content and proline content. The genotypes responded differently to drought stress indicating that there is sufficient genetic variability that can be utilized further in breeding for drought stress within the cowpea species.

“…The leaf relative water content representing the plant water status gives a biological baseline or reference. It is a significant determinant of metabolic activity and tissue or organ survival (Kalariya et al, 2015;Shinde et al, 2018). A maximum of 47.13C, minimum of 30.68C and mean of 40.08C CT were recorded and it was lesser in TMV2 (41.4C) than TMV2NLM (38.0C) (Table 2).…”

Background: Genotype sensitivity to mid-season drought suggests the possibility of identifying genotypes with high yield potential and low sensitivity to mid-season droughts. The overall objective of the present research was to select genotypes with high tolerance to mid-season moisture stress. This effort includes assessing the variation of physiological and productive traits among RIL population lines, assessing the range of correlation for physiological and productive traits across two seasons and identifying a set of contrasting material under drought stress conditions. Methods: To assess the recombinant inbred lines (RIL) under moisture stress, we screened RIL population of groundnut with 432 lines and parents under mid-season drought stress conditions in rabi for two years. During the drought stress period, soil moisture content (SMC) and temperatures were measured. SPAD chlorophyll meter reading (SCMR), specific leaf area (SLA), relative water content (RWC), visual wilting rate (VWR) and canopy temperature (CT) were recorded at the end of the stress period. Pod yield per plant (PYPP), kernel yield per plant (KYPP) and shelling percent (SP) were recorded at harvest. Result: Physiological traits and yield attributes varied significantly among the RIL population. The Genotype by Trait biplot (GT biplot) revealed that the yield attributes showed a positive association with RWC, SCMR and a negative association with SLA, VWR and CT. The inbred lines were classified as visually healthy with high physiological and high or moderate yield traits; visually wilting with low physiological and low yield traits under a drought environment. The identified superior and inferior lines werefurther utilized to analyze genomic regions and genes for drought tolerance in groundnut.
