<p style="text-align: justify;">The food security is a huge problem with the increase in population of the Pakistan. Maiz (Zea mays) is one of the major cereal crop and has the capability to compete with the production as well as supporting the controlling applications. As, the modern genotypes has the good potential to resist with the potassium (K) application into the field, an experiment was conducted on K levels with 0, 30, 60 and 90 kg ha-1. Maize genotypes viz MM-50, MM-44, ZMS-52, ZMS-51, ZMS-40, ZMS-06, GV-41, Kiramat-2C, 325-PW and Babar-1C were tested into the field. Our results concluded that K levels had a significant effect on grain yield and yield components. Application of K at 60 kg ha-1 showed good yield compared to all other levels of K applications. The tested genotypes also had a significant effect on the tested traits. The genotype (MM-50) showed maximum grains yield (3924 kg ha-1) and maximum yield components to all the genotypes. Maximum grains yield (4593 kg ha-1) and 1000 grain weight (260.4 g) were obtained from genotype (MM-50) at K level of 60 kg ha -1.</p>

<div style="text-align: justify;">The utilization of organic fertilizers in farmlands to enhance crop productivity and soil health is increasing globally. Compost and charcoal obtained from the decomposition and slow pyrolysis (respectively) of plants and animals wastes. Here we evaluated the effect of charcoal and compost on the growth and yield of wheat (Triticum aestivum L.) at Agriculture Research Farm Peshawar, Pakistan during 2014-2015. Results showed that the application of compost and charcoal as sole or in combination significantly affected the yield and yield attributes of wheat. Data divulged that the maximum numbers of plant tillers (337 m-2), number of productive tillers per plant (313 m-2), number of grains per spike (56 spike-1) and 1000 seeds weight (50.2 g) were produced by the combined application of compost and charcoal at 5+5 Mg ha-1 while plant height (95.3 cm) was enhanced with the application of charcoal at 10 Mg ha-1. The gain (4106.7 kg ha-1) and biological yield (8473.3 kg ha-1) was significantly increased with the compost application at the rate of 10 Mg ha-1. These results proved that charcoal and compost can be used as organic fertilizers for boosting growth and yield performance of wheat under the agro-climatic conditions of Peshawar, Pakistan.</div>
