Biochar, relative water content, chlorophyll stability index, proline Keywords:The field experiments were conducted at Agricultural College and Research Institute, Madurai during summer and winter irrigated cotton seasons of 2016 and 2016-17. Experiments were laid out in split plot design with three replications. Moisture regimes were assigned to the main plots viz., Irrigation at IW/CPE ratio 0.4 and 0.8. The subplot comprises with moisture stress management practices viz., Cotton stalk biochar @ 5 t ha -1 , Cotton stalk biochar @ 5 t ha -1 +Crop residue mulch @ 5 t ha -1 , Cotton stalk biochar @ 5 t ha -1 +Crop residue mulch @ 5 t ha -1 and PPFM @ 500 ml ha -1 on 75 and 90 DAS, Prosopis biochar @ 5 t ha -1 , Prosopis biochar @ 5 t ha -1 +Crop residue mulch @ 5 t ha -1 , Prosopis biochar @ 5 t ha -1 +crop residue mulch @ 5 t ha -1 and PPFM @ 500 ml ha -1 on 75 and 90 DAS and Control. The stress physiological parameters observed viz., Relative leaf water content, Chlorophyll stability index and Leaf accumulated proline were greatly influenced during moisture stress period. The Maintenance of higher relative water content helps in sustaining the photosynthetic capacity of plants which ultimately contributes to higher yield. In this study higher relative leaf water content, chlorophyll stability index, lower leaf accumulated proline and higher yield of cotton was recorded in irrigation at IW/CPE to 0.8 and Prosopis biochar @ 5 t ha -1 +crop residue mulch @ 5 t ha -1 and PPFM @ 500 ml ha -1 .

“…In fact, Si raised the relative leaf water content (RWC) and the stomatal size in severely drought-stressed collards to the same conditions that were found in well-watered plants. Drought-stressed plants usually have lower RWC (Farooq, Wahid, Kobayashi, Fujita, & Basra, 2009;Sampathkumar, Pandians, Jeyakumar, & Manickasundaram, 2013), but addition of Si increased the RWC in drought-stressed maize (Zargar & Agnihotri, 2013), wheat (Gong & Chen, 2012;Pei et al, 2010) and pepper (Lobato et al, 2009) to similar levels of non-stressed plants. The increased RWC shows that Si improved water uptake and retention in drought-stressed collard.…”

It was postulated that Si‐mediated plant resistance to herbivory changes with soil water status, increasing when plants are under drought stress. We subjected collard (Brassica oleracea) to such soil variables and assessed plant responses and effects on the leaf‐chewing larvae of Plutella xylostella and the sap‐sucking aphid Brevicoryne brassicae. Silicon accumulated in collard leaves independently of soil water conditions, but it influenced mainly drought‐stressed plants. Silicon suppressed harmful effects of drought on leaf and root length and raised leaf water content and stomatal size to the same conditions of well‐watered plants. Drought stress reduced hemicellulose and cellulose, but Si did not influence them or lignin. Combination of drought and Si increased total and soluble leaf nitrogen. Drought decreased total glucosinolates, but Si increased such defence metabolites to similar concentrations that were found in well‐watered plants. Nutritional changes mediated by drought and Si in fibre, leaf water content, soluble nitrogen and glucosinolates did not increase insect performance in any feeding guild. Instead, caterpillars performed worse in drought‐stressed or Si‐treated collards, mainly in plants under combined conditions. Silicon improved plant resistance to drought and herbivore stresses.

“…At first sight, deliberate exposure to water stress and induction of stress tolerance may be used for maximizing water use efficiency by agricultural crops (Sampathkumar et al 2013). However, this technique may be impractical if a high biomass production is desirable, and the issue may become even more complex when insect pests are taken into account.…”

An initial destabilization of functions triggered by drought stress in plants is followed by acclimatization and acquisition of tolerance; however, knowledge remains limited on drought-mediated changes in plant quality for herbivores. We tested whether a water-stressed fast-growing plant negatively affects host-specialist insects in both sap-sucking and leaf-chewing feeding guilds. Collards (Brassica oleracea var. acephala) were grown in wellwatered, slightly water-stressed and severely water-stressed conditions. Decreasing soil moisture adversely affected plant development, assessed as a reduction in leaf number and size, stomatal size and relative water content. Severely stressed plants had less fiber and glucosinolates; however, they showed more total nitrogen and lipids. Larval survival, pupal weight, reproductive rate (Ro) and rate of population growth (r) were lower when the leaf-chewing Plutella xylostella was reared with severely stressed collards. In multiple-choice tests, moths laid fewer eggs on leaf discs of collard that were exposed to drought. The fecundity of the sap-sucking Brevicoryne brassicae was higher and the development of alates was lower when insects were fed on plants kept in well-watered regime as compared to slight-stress and severe-stress. Despite higher nitrogen content and fewer glucosinolates, a higher level of leaf surface wax in severely stressed collards possibly decreased food quality for both herbivores. Thus, hostspecific herbivores of different guilds showed similar responses to drought-stressed, fast-growing plants. Waterstressed crops could discourage the attack of specialist insects, but the intensity of the stress that is required to achieve this effect will greatly reduce crop production, in terms of plant growth or foliage increment.
