“…The cultivation of STRVs encourages the farmers to invest more on inputs due to reduced risks of crop failure. This results in an increase in farm output during all the years, irrespective of the severity of stresses [128][129][130]. Besides, STRVs represent an important adaptation to climate change that can increase farm productivity and ensure production from the affected land.…”

Rice is globally a major food crop and its production has progressively been affected by various types of abiotic stresses especially drought, flooding, salinity, heat and cold in most of the cultivable rice ecosystems. The incidence, intensity and duration of these stresses are anticipated to aggravate due to climate change consequences, demanding resilient yields in these situations to be essential. Present paper deals with reviewing various types of abiotic stresses and their mitigation strategies for enhancing and stabilizing rice production in stress prone areas. Review of available literature pertaining to the study area has been used as research methodology for this paper. The available literature suggests that stress-tolerant varieties can serve as the most viable strategy to contribute in coping with the problem of abiotic stresses. Although, good progress has been made in the development of stress-tolerant rice varieties (STRVs) and incessant efforts are being made to spread these varieties in target areas, adoption by farmers is yet to meet expectations. Advantage, affordability, awareness and availability are the main factors responsible for adopting of any technology. The adoption of stress-tolerant varieties has not reached its potential, predominantly due to the lack of awareness and non-availability of seeds amongst farmers. Strategic and intentional collaborations should be ensured for scaling the sustainable delivery and diffusion of STRVs. A promotional roadmap that ensures the linkages between private and public seed sectors remains the key factor for its successful adoption. Similarly, strengthening of formal, informal and semi-formal seed systems is crucial to accelerate the dissemination of these varieties. There is an imperative need to create strategic plans for the development of varieties possessing multiple stress tolerance. Significant investments for sustainability of rice production in stress prone areas form the essential component of long-term agricultural development. The sooner these investments and strategies are accomplished, the greater the gains are expected.

“…In India, maize is cultivated on an area of 9.86 million hectares (mha) with a production of 31.51 million tonnes and a productivity of 3.19 t ha-1 [1]. In Jammu and Kashmir, maize is the second most important cereal crop after rice [2], cultivated over an area of about 3.08 lakh hectares with a production of 5.12 lakh tons and a productivity of 1.7 t ha-1 [3].…”

In the Kharif season of 2021, a field experiment was conducted at the crop research farm of the Division of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir. The primary objective of the study was to investigate the phenology of maize hybrids in relation to agrometeorological indices. The experimental design included two factors: Factor A, representing different irrigation regimes at various growth stages (I1 to I6), and Factor B, consisting of two maize hybrid varieties (Shalimar Hybrid-2 and Shalimar Hybrid-3). The irrigation treatments ranged from early vegetation stage to rainfed conditions. The experiment followed a split plot design with three replications. Results indicated that the treatment I5 (Irrigation at IW/CPE ratio of 0.8) and Shalimar Hybrid-3 exhibited the highest values for key agrometeorological indices, including GDD, HTU, PTU, and HYTU. These findings provide valuable insights into optimizing irrigation practices and selecting suitable maize hybrids for enhanced phenological performance.

“…In Jammu and Kashmir, the crop is cultivated over an area of about 0.31 million ha with the production of about 0.52 million tonnes and productivity of 1.7 tonnes ha -1 . In Kashmir valley, 14.50 per cent of the maize area is irrigated and the remaining 85.5 per cent is rainfed (Ahangar et al 2020). Maize requires 450-600 mm of water during its life cycle at critical stages of crop growth viz., knee height stage, flowering stage (tasseling and silking) and grain filling stage (Aslam et al 2015).…”

Drought is one of the major constraints affecting the economic yield of maize worldwide. Present study was carried out to select the surrogates for drought resilience in 70 maize landraces collected from diverse agro-ecologies of Kashmir Himalayas. Significant variation was observed among the genotypes for all the traits under well-watered and drought conditions. Due to the drought stress, the highest reduction was observed for the canopy temperature (175.18%), followed by root volume (69.77%), top root biomass (69.1%), shoot biomass (67.2%), bottom root biomass (53.75%), chlorophyll content (22.85 SPAD units) and shoot height (21.63%). The reduction was also recorded for other traits like shoot to total biomass ratio (2.70%), relative water content (13.42 %), cell membrane stability (17.33%) and rooting depth (19.86%). Root to total biomass ratio was found to increase in response to drought stress (7.69%). A positive significant correlation was observed between grain yield and root volume, top root biomass, bottom root biomass, rooting depth, root to total biomass, chlorophyll content, cell membrane stability, canopy temperature depression and relative water content. These can be used for selection of appropriate surrogates of drought tolerant genotypes. The landraces viz., KD-L35, KD-L37, KD-L19, KD-L23, KD-L17, KD-L21, KD-L46, KD-L43, KD-L29, KD-L25 and KD-L38 showed promising performance under drought for most of the surrogates identified. The landraces selected can be used as sources of novel and/or favourable alleles to breed for climate resilient maize cultivars. Bangladesh J. Bot. 51(3): 487-498, 2022 (September)
