It is grown in various regions of the world and is subjected to diverse environmental or nutritional constraints that affect its growth and productivity. Among these constraints, NPK deficiency is a major nutritional constraint in alkaline-calcareous soils. The problem of NPK deficiency in cotton has been addressed by the application of different NPK fertilizers; however, their efficacy in alkaline soils is not well understood. This experiment was carried out to look into the comparative effect of NPK fertilizers, such as DAP, Urea, SOP, CAN, and NP on the growth of cotton. The aim of the findings was to assess the impact of different NPK fertilizers on the growth and productivity of cotton in alkaline-calcareous soils. Five different treatments were used in the experiment, which was carried out using a randomized complete block design, a control treatment and three replications. The results showed that the treatment with NP+CAN+SOP (T5) had the highest number of bolls (46.75), followed by T3 (42.25) with DAP+CAN+SOP, and T4 (36.55) with NP+ Urea + SOP. The highest plant height (163.48 cm) and fresh stalk weight (290 g) were observed in T5. Similarly, the maximum yield (2350 kg/ha) was observed in T5 followed by T3 (2081 kg/ha). T5 also showed highest relative water content (94.7%) and staple length (27.4 mm)). In conclusion, the application of NP+CAN+SOP (T5) had a significant optimistic impact on the growth and productivity of cotton in alkaline-calcareous soils. The findings of this investigation offer insightful information on the efficacy of NPK fertilizers for cotton production in these soils and can be used to make informed decisions for future fertilizer management practices.
Wheat is a staple food globally and is greatly affected by nutrient management practices usually ... more Wheat is a staple food globally and is greatly affected by nutrient management practices usually required for fixing soil organic carbon and optimum growth of the crop. Therefore, to determine the effectiveness of amendments of organo-mineral and tillage systems on phenology, growth of wheat, and yield and yield components, a field experiment was conducted at the Agronomic Research Area, University of Agriculture Faisalabad. The experiment was triplicated to minimize the error percentage under a randomized complete block design (RCBD) with a split-plot arrangement. There were two tillage practices such as reduced tillage and conventional tillage which were randomized in main plots and six nutrient management practices as Control, required levels of N from NPK, farmyard manure (FYM), poultry manure (PM), half of N from NPK + half of N from FYM, and half of N from NPK + half of N from PM respectively. These treatments were randomized in subplots. Data on growth, yield, and phenology was recorded during the experiment according to standard procedure. Results revealed that wheat crops reached earlier phenological stage i.e., tillering, anthesis, and maturity under the application of conventional as well as reduced tillage along with poultry manure (PM) while reducing tillage along with control (no fertilizer) has shown delay in phenological attributes. Yield and yield parameters showed highly significant variations. The application of reducing tillage along with nutrient management practices performed better in terms of yield attributes such as the number of grains per spike, grain yield, and biological yield. Whereas conventional tillage showed poor results regarding yield-related attributes. Application of reduced tillage along with the farmyard manure performed better regarding growth parameters i.e., leaf area index, leaf area duration, crop growth rate, net assimilation rate, and total dry matter, while conventional tillage along with control (no fertilizer) recorded poor results. For statistical analysis, Fisher's method of analysis of variance was Muhammad Zubair Ayyoub 18 used and assessed on a 5% probability level. The treatment means were compared using Tukey's test of HSD.
