Growth and development of cereal crops are linked to weather, day length and growing degree-days (GDDs) which make them responsive to the specific environments in specific seasons. Global temperature is rising due to human activities such as burning of fossil fuels and clearance of woodlands for building construction. The rise in temperature disrupts crop growth and development. Disturbance mainly causes a shift in phenological development of crops and affects their economic yield. Scientists and farmers adapt to these phenological shifts, in part, by changing sowing time and cultivar shifts which may increase or decrease crop growth duration. Nonetheless, climate warming is a global phenomenon and cannot be avoided. In this scenario, food security can be ensured by improving cereal production through agronomic management, breeding of climate-adapted genotypes and increasing genetic biodiversity. In this review, climate warming, its impact and consequences are discussed with reference to their influences on phenological shifts. Furthermore, how different cereal crops adapt to climate warming by regulating their phenological development is elaborated. Based on the above mentioned discussion, different management strategies to cope with climate warming are suggested.

Aphid is a major pest of wheat that causes substantial agricultural damages to wheat crop annually. In the present study, experiments on ecofriendly management of this pest were conducted at the experimental area of Arid Zone Research Institute (AZRI), Bhakkar. The trials were laid down in Randomized Complete Block Design (RCBD) with three replications. Data was collected at seven days interval by counting method. As far as efficiency of yellow sticky traps is concerned, the plot having 4-traps captured maximum (848.07) aphids. As a result, minimum (11.16 aphid tiller-1) were observed in the respective plot. The same plot exhibited maximum population reduction (71.93%) and grain yield (6617.9 kg ha-1). The plot having 1-trap captured minimum (257.33) aphids. Consequently, maximum (33.37 aphids/tiller) were found in the field. The same treatment showed minimum population reduction (23.99%) and grain yield (5489.1 kg ha-1). Chrysoperla carnea was found a voracious predator of the pest. The plot having 4-egg cards of this predator showed minimum (7.69 aphids tiller-1) with maximum (49.50%) population reduction of the aphid followed by 8.78 aphids/tiller in the plot having 3-egg cards with 42.56% population reduction. Lowest population reduction (12.33%) was found in the plot having 1 egg card.

C itrus fruits are produced in many tropical and subtropical countries of the world. Pakistan is also one of the largest producers of Citrus (Kinnow) fruit along with leading countries like Brazil, USA, China, Japan and Maxico etc. (Amador, 2008). Moreover, citrus, in the entire scenario of Pakistan fruit culture constitutes to be the major fruit crop of the country both in area and production. These fruits Abstract | An elaborated study on evaluating quality characteristics of exotic fruits belonging to orange group of citrus was carried out at Citrus Research Institute Sargodha. The candidate varieties/cultivars were Rhode Red Valencia, Cara Cara, Amber Sweet, Sun Star and Salustiana. All of these different five citrus varieties evaluated objectively assessing their suitability both for direct consumption and value addition. The work spread over two years (2018and19) produced distinctive results for their commercial exploitation. The attributes in analytical work for fruit quality evaluation were fruit size, weight, peel thickness, peel percentage, juice percentage, rag percentage, total soluble solids (TSS), acidity, TSS/acid ratio, number of segments, and number of seeds, maturity period and degree of granularity. This was ever important study in Pakistan for evaluating the citrus exotic material of latest generation. This endeavour led to the sound recommendation of sweet oranges like Rhode Red Valencia and Sun Star in the two years of study. In case of taste imparting characteristics like TSS, acidity and their respective ratio in the
