Wheat is a staple food for approximately 35% of the global population, with Pakistan being the largest consumer, consuming 120 kg per person annually. The country cultivates 24.2 million tonnes of wheat over 8.7 million hectares. Wheat is rich in protein (>10%), fats (2.4%), and complex carbohydrates (79%). Given its significance, wheat is a key priority in Pakistan’s agricultural policy. However, wheat cultivation faces challenges, particularly from abiotic stresses like drought, which reduces soil moisture content. These stresses cause alterations at morphological, biological, molecular, and physiological levels, leading to decreased production and potential crop failure. Drought tolerance in wheat is complex, as low water availability can induce toxicity, nutrient deficiencies, and temperature instability, all of which affect plant function. To develop drought-resistant wheat, both traditional breeding and genetic engineering approaches are used. This paper explores the latest technologies for improving drought resistance in wheat, including drought-inducible genes, promoters, and transcription factors. Integrating molecular breeding strategies with conventional methods is recommended to develop resilient cultivars tailored to local environmental conditions, ensuring sustainable wheat production amidst increasing drought pressures.

Chickpea (Cicer arietinum L.) is a vital legume crop regarding its high protein content and adaptability to semi-arid conditions, which make it a stable in diverse agricultural systems. Current experiment was designed to evaluate the effects of water soaking durations and NPK levels on the growth of chickpea under semi-arid conditions of Thal-Khushab, Punjab. The experiment was conducted in Randomized Complete Block Design (RCBD) with 4 replications and 20 treatments consisting of all possible combinations of 5 water soaking durations (W0=no water soaking, W1=soaking for 30 mints, W2= soaking for 60 mints, W3= soaking for 90 mints, W4=soaking for 120 mints) and 4 fertilizer levels (NPK) (F0=no NPK, F1=20:40:20 kg ha-1, F2= 25:50:25 kg ha-1, F3=30:60:30 kg ha-1). Data of growth parameters was recorded and analyzed using ANOVA, LSD test which showed a significant effect of the treatments. Among the growth parameters, the minimum emergence time was recorded under W2F2 (5.96 days), maximum plant stand count (100m-2) was recorded with W2F1, maximum Primary branch number (8.37 per plant) under W2F2, maximum plant height (120.59 cm) with W1F3, maximum Biomass Yield (kg ha-1) with W0F3 and maximum harvest index (6.3) was recorded with treatment W4F2. Correlation test was also conducted, which showed mixed response including positive, negative and no association among the different parameters.

Grapes (Vitis vinifera) are woody perennials propagated mainly via cuttings, with berries that can be green, pink, golden, black, red, or purple. In this study, we investigated the effect of Indole-3-Butyric Acid (IBA) concentrations on the propagation of grape cultivars using cuttings in the monsoon season under greenhouse conditions. The experiment was designed as a Completely Randomized Design (CRD) with each treatment replicated three times. The medium used was solarized sand, free from pathogens and weed seeds. Cuttings, 6–8 inches long and from three grape cultivars (“King’s Ruby”, “NARC Black”, and “Flame Seedless”), were treated with 0 (control), 2000, 3000, and 4000 ppm IBA concentrations. Various parameters were measured, such as the number of leaves per cutting, shoot length, rooting percentage, and survival percentage. The data showed a significant effect of IBA concentrations (p<0.05). “King’s Ruby” showed the highest number of leaves and roots per cutting at 4000 ppm IBA, while “Flame Seedless” responded with the most extended shoot and root length at 2000 ppm IBA. Interestingly, “Flame Seedless” without IBA application had the best shoot diameter, rooting percentage, and survival rate. These results suggest that grape cultivars respond differently to IBA concentrations.
