Current research wasconducted to analyze the coefficient and distribution of direct and indirect influence of yield components and earliness characteristics in wheat genotypes. Both experiments were carried out at the Pot House of the (NIA Nuclear Institute of Agriculture, Tandojam)(Latitude: 25.433. Longitude: 68.533), the experiment was established as a randomized complete block design (RCBD). Therewere six varieties of wheat, namely IBWSN1010, IBWSN 1025, TD1, ESW9525 Chakwal86 and Khirman, which were used to study the correlation coefficient between morphological and physiological traits. The study was based on fifteen (15) morphologically and physiologicallytraits that were observed. The analysis of variance showed significant differences between the characteristics of the varieties. The ESW9525 showed better performanceforall morphological and physiological traits. The correlation and the coefficientanalysisshowed that the days to maturity and the days to growth predicted significant positive predictions related to the height of the plant (cm) and the length of the ear. Days to75% heading and days to 75% maturity showed negative and positive effects forosmotic potential, relative water content in% and total chlorophyll content in%. Plant height (cm) had negative and positive and significant withtiller plant-1. Therefore,in our research trial,variety ESW9525 may be favorable for hybridization in orderto produce a promising and drought tolerant wheat cultivar

Maize (Zea mays L.) is a valuable forage crop. It is also an essential and promising crop for the Republic of Kazakhstan, cultivated in the southern zone. Some new maize hybrids have been introduced, which have been beneficial for high yields with less fertilizer input. This study aims to introduce the new maize hybrid, Arman 689, for the judicial use of fertilizer and the high yield. This study was carried out in 2015 in the southeast region of Kazakhstan. There are five treatments with various mineral fertilizer and poultry manure doses: 1. control (T0), 2. P60 K100 (T1), 3. N100P60K100 (T2). 4. N100P60K100 + 40 tons of manure/ha (T3), and 5. N100P60K100 + 60 ton of manure/ha (T4). The fertilizers used were ammonium nitrate (N—34.6%), amorphous (N—11.0%, P2O5—46.0%), and potassium chloride KCl (K2O—56%). The results showed that the grain yield ranges from 5.51 t/ha (T0) to 8.49 (T4) t/ha. The protein contents in the maize grain varied from 9%(T0)–11.3%(T4). The grain nitrogen content accounted for 54.2 to 52.0%. The nutrient uptake results by different treatments indicated that nitrogen contributed to 41.5% of the total yield increase. Using manure in combination with mineral fertilizers reduced the payback of the applied resources, as the payback of T2–T4 was 8.8–9.1 kg of grain. With the application of recommended mineral fertilizer (NPK), the protein yield was 0.83 t/ha, 0.33, and 1.22 t/ha higher than T0 and T1 treatments, respectively. There was no significant yield difference under T3 and T4 treatments (p > 0.05). Overall, the treatment, NPK + 40 tons of manure, was proved the ultimate for the Arman hybrid in providing the optimum quantity and quality of maize, as well as reducing the payback cost (8.8–9.1 kg of grain). It is suggested to apply NPK-recommended doses along with manure in maize (Arman hybrid)-based intercropping systems to utilize the resources efficiently.
