Drought is one of the most emerging threat that causes a severe reduction in cotton plant growth and development. Being cotton is a major cash crop has great threat to prevailing drought events in Pakistan. A field experiment was conducted in Kharif season 2018 at Research Area of MNS-University of Agriculture, Multan, Pakistan to assess the role of foliar applied kaolin and jasmonic acid on vegetative growth, gas exchange and reproductive traits of cotton under normal irrigated and artificial water deficit conditions. The experiment was laid -out in a factorial randomized complete block design with split – split plot arrangement. Main plots were allocated for irrigation levels, sub-plots for two -cotton genotypes viz. NIAB − 878 and SLH − 19 while sub – sub plots for treatments of kaolin and Jasmonic acid. Water deficit stress was created by skipping irrigation at flowering for 21 days. Foliar sprays of Kaolin (5%, w/v) and Jasmonic acid (100 μM) were applied alone or in combination at 60 days after planntinon both to normal irrigated and water-stresse skip irrigation while irrigation water alone was sprayed in control plots. Both cotton genotypes responded variably to normal irrigated and skip conditions. Skipping irrigation for up to 21 days at flowering caused a significant decrease in leaf relative water content, SPAD values, net photosynthetic rate and seed cotton yield in both the genotypes. Seed cotton yield showed an overall decline of 24.7% in skip over Normal irrigated crop. The genotype NIAB − 878 produced maximum seed cotton yield of 3.304 Mg ha −1 in normal that dropped to 2.579 Mg ha −1 in skip, thus showing an average decline of 21.9 %. Similarly, SLH − 19 produced 2.537 Mg ha −1 seed cotton under normal that dropped to 1.822 Mg ha −1 in skip, showing an average decline of 28.2%. The Application of Kaolin and JA Jasmonic acid, either applied individually or in combination, improved vegetative and reproductive development of both cotton varieties in normal and skip regimes. However, combined kaolin and Jasmonic Acid application proved to be more beneficial in terms of seed cotton production and other parameters studied.

Mentha arvensis or mint is a renowned medicinal and aromatic plant. It is annual plant and cultivated in the tropical and sub-tropical regions under irrigation. Its cultivation has significant importance, such as for food flavoring, medicinal applications, essential oil applications, and also using in traditional purposes. Its essential oil contains many components phenolic, aldehydes, ketones, and carbohydrates. Menthol is a fundamental component of Mentha arvensis essential oil. Menthol has also several industrial applications, especially in food, cosmetics, pharmaceuticals, and by-products. There are many types or variations of menthol found in Mentha arvensis depending on the species or cultivars as well as cultivation conditions, such as weather, irrigation, soil type, pruning, and other agronomical practices. It has interesting and valuable botany, morphology, and ecology. Its growth rate is strongly affected by the change of variables, such as pH, temperature, and nutritional values of soil. The extraction of essential oil and the post-harvest analysis are done by using traditional methods for Mentha arvensis oil production in developing countries. Research on oil extraction methods, maximizing yield per hectare, and optimum preservation are needed for the further, especially in post-harvest of mint leaves and roots.

Two Experiments were carried out in 1999 season. The first was at the experimental farm of Rice Research and Training Center (RRTC),Sakha, whereas the second was at the experimental farm of Gemmiza Research Station. The study aimed to investigate the effect of rice blast disease on yield losses at different growth stages of cvs. Giza 171, Reiho and Giza 176. The cultivars were evaluated in split-plot design as a main plots, wheras the treatments (protection by Beam at the rate of 100g/ fed) at both tillering and heading stages, artificial inoculation with spore suspension of Pyricularia grisea (5×10 4 spores/m 2 ( at tillering and or heading stage (milking, soft dough) and natural infection were allocated as Sub-plots. The highest severity and area under disease progress curve (AUDPC) for leaf blast infection were obtained from artificial inoculation at tillering stage. Also, the highest severity and AUDPC of panicle blast infection were recorded from artificial inoculation at milking stage. Giza 171 was the highest susceptible cultivar during vegetative stage, while Giza 176 was the most susceptible cultivar during heading stage. Maximum actual loss due to blast infection in grain yield and 1000-grain weight was obtained from artificial inoculation at milking stage. Panicle blast infection had stronger influence than leaf blast infection. Whereas yield losses due to panicle infection of Giza 171 were two folds compared to those due to leaf infection. These losses were three and four folds in case of Reiho and Giza 176.
