Vulnerability of agriculture to climate change is becoming increasingly apparent in recent years. During 2014 and 2015, India experienced trails of unusually widespread and untimely hailstorm events. The increased frequency of hailstorm events, especially in vulnerable ecosystem of Deccan Plateau region of India demanded appropriate measures to minimize adverse impact on agricultural crops. Therefore some of the post-hail measures including nutritional supplement, plant bio-regulators and canopy management were evaluated in field trials conducted at Maharashtra, India during 2014 and 2015. Amongst these, pruning of the hardy and indeterminate eggplant crop induced effective branches, which produced more flowers and fruits. Nitrogen supplemented with urea drenching and stress alleviating effects of salicylic acid promoted recovery in maize while drenching with humic acid along with spraying of potassium nitrate improved productivity of onion. These studies indicate the potential of technological interventions to cope with extreme events such as hailstorms.Keywords

This study analysed frost heave lands in the cold arid Leh–Ladakh region of the Himalaya, India through semi-detail field survey and remote sensing. Most of these sites are highland grasslands occurring along the alluvial plains of rivers in the Leh and Nubra valleys. The study identified the occurrence of some unique frost heave patterns whose morphometry varied from simple, isolated to complex ones with elongated, coalesced and superimposed bedforms. These lands can be further subdivided into vegetated and degraded types. The degraded forms exhibited several cracks, dry, collapsed and slump structures. Invasion of Cirsium arvense over native grass species, soil salinity and feeding pressure by livestock have been identified as major land degradation factors. C. arvense has replaced the native vegetation on frost heaves and has allowed Carex species to grow, which is known to degrade and deplete the pasture ecology.Keywords

Makhana (Euryale ferox) is a high-value commodity of nutritional, medicinal and ritualistic significance. North Bihar has occupied a prominent position in terms of both production and productivity of makhana not only in India, but across the globe. Leaf blight disease on makhana was noticed in April 2018, with a severity of 15–20% in a survey of farmers’ ponds in North Bihar. Symptoms of the disease were circular, small, light-brown, necrotic, sunken lesion that later turned into a large, dark, blighted area in the leaves. Blighting of fruits was also noticed during June and July 2018. Blighted fruits were small, distorted and twisted with less seed. Alternaria alternata was identified as the pathogen causing the disease based on morphological and cultural characteristics of the culture maintained on potato dextrose agar from symptomatic leaf and fruit samples. The fungus gave rise to greyish to grey–black colonies with obclavate to obpyriform, catenulate conidia in chains. Conidia consisted of 2–5 horizontal and 0–2 vertical septa and measured 15–60 ´ 5–9 mm in dimension. Molecular confirmation was done by sequence analysis of the internal transcribed spacer (ITS) regions of rDNA using ITS1 and ITS4 primers. Eventually, pathogenicity test inferred that leaf and fruit blight in makhana are due to A. alternata infectionKeywords
