There is a need to develop more efficient nutrient management strategies to maximize wheat (Triticum aestivum L.) grain yields and increase grain protein levels. Urea, most widely used N fertilizer, is susceptible to substantial losses, resulting in low nitrogen use efficiency (NUE). This study assessed the effect of N and K fertilization on hard red spring wheat production under dryland no-till conditions in Montana. A field experiment was conducted during one growing season at two locations in Northcentral Montana. Fertilizer N was applied as urea (46-0-0) or as a urea-KCl (50:50 blend) at planting to achieve two target N rates, 135 and 270 kg N ha −1. Biomass weight, N content, and sensor-based Normalized Vegetative Difference Index (NDVI), yield, test weight, and grain protein content of wheat was evaluated. Results indicated that: (a) N may increase wheat grain quality (protein content) even when wheat yield is not increased, (b) KCl application, along with N, may result in greater wheat biomass production and grain protein values, and (c) NDVI may be more sensitive to the amount of produced biomass than to N content of that biomass. In conclusion, even if yield response to N is minimal, N is beneficial for improving grain protein content of wheat. Addition of KCl along with N may produce greater wheat biomass and increase biomass N content. The NDVI may be more sensitive to the amount of produced biomass than to its N content.

Leaf rust (Puccinia triticina f. sp. tritici) is universal threat for wheat production. In present study, effect of sowing dates (30 th Oct; 10 th , 20 th and 30 th Nov) and NPK levels (N1-80Kg, N2-100Kg, N3-60Kg, P 1-58Kg, P 2-70Kg, P 3-50Kg, K 1-63Kg, K 2-75, K 3-55Kg) against leaf rust and their impact on 1000 grain were evaluated under Randomized Complete Block Design (RCBD) at Plant Pathology research area in University of Agriculture Faisalabad during 2009. Results showed that among 3 fertilizers, K exhibited significant result as compared to N, P and control for management of leaf rust and produced maximum 1000 grain weight. Among sowing dates, rust severity was minimum in early sown (30 th Oct) and maximum in late sown (30 th Nov). Thus early sowing with different levels of NPK has paramount importance to combat leaf rust severity effectively.

An experiment was conducted to study dry matter partitioning, yield and grain protein content of fine aromatic Boro rice (cv. BRRI dhan50) in response to nitrogen and potassium fertilization. The experiment consisted of four levels of nitrogen viz., 0, 50, 100 and 150 kg/ha and four levels of potassium viz., 0, 30, 60 and 90 kg/ha. The results revealed that at growth stage, the highest total dry matter partitioning and accumulation were obtained from 150 kg N/ha along with 90 kg K/ha at physiological maturity stage. At harvest, the highest number of tillers/hill (8.58), number of grains/panicle (113.9), grain yield (5.15 t/ha) and grain protein content (8.30%) were obtained from 100 kg N/ha along with 90 kg K/ha. Total dry matter partitioning and accumulation were greatly influenced by the application of 150 kg N/ha along with 90 kg K/ha. Application of 100 kg N/ha along with 90 kg K/ha interaction appeared as the promising practice in fine aromatic rice (cv. BRRI dhan50) cultivation in terms of yield and grain protein content.
