“…However, numerically the highest value of N, P, K content of 2.169, 0.308 and 1.470 per cent, respectively in grain and N, P, K content 0.581, 0.205 and 1.097 per cent, respectively in straw was recorded with application of 30 kg K 2 O ha -1 (K 3 ) and the lowest value of N, P, K content of 2.143, 0.302 and 1.451 per cent, respectively in grain and N, P, K content of 0.562, 0.197 and 1.083 per cent, respectively in straw was recorded by control (K 1 ). The results of present investigation are conformity with results observed by Patil et al (2017). They reported that no significant difference in primary nutrients content (N, P and K) in grain and stover of maize with varied levels of K 2 O i.e., 50, 75, 100 and 125 per cent of recommended dose of K 2 O.…”

Background: Maize (Zea mays L.) is one of the most versatile emerging crops having wider adaptability under varied agro-climatic conditions. Nitrogen though an expensive input is very important as it is intimately involved in the process of photosynthesis and directly reflected in the total dry matter production. Phosphorus is involved in a wide range of plant processes from permitting cell division to the development of a good root system and for ensuring timely and uniform ripening of the crop. Potassium plays a vital role as macronutrient in plant growth and sustainable crop production. The current study aimed to study the effect of nitrogen, phosphorus and potassium on yield, quality, nutrient content and uptake on hybrid maize (Zea mays L.) under south Gujarat condition. Methods: A field experiment was conducted during rabi season of the year 2019-20 to study the effect of different levels of nitrogen, phosphorus and potassium on yield, quality, nutrient content and uptake by hybrid maize (Zea mays L.). In this experiment twelve treatment combinations consisting of three levels of nitrogen fertilizer, two levels of phosphorus fertilizer and two levels of potassium fertilizer were tried in factorial randomized block design with three replications. The protein content and nitrogen, phosphorus, potassium content and their uptake by seed and stover and available nitrogen, phosphorus, potassium status in the soil after harvest of the crop were determined by different methods. Result: The result showed that quality parameter viz., crude protein content, crude protein yield, nutrient content and uptake by grain and straw of hybrid maize were increased with the increased in nitrogen (180 kg N ha-1), phosphorus (60 kg P2O5 ha-1) and potassium (30 kg K2O ha-1) level.

“…(2014) [16-18, 25, 26] also reported significant effect of K fertilizer on potassium uptake by crop. Patil et al (2017) [14] reported that significantly higher total N, P, K uptake by maize crop was recorded when 125% of K 2 O was applied. The increase in uptake of zinc with increasing levels of K may be due to the favourable effect of K on photosynthesis and metabolic processes thereby augmenting the production of photosynthates and their translocation to different plant parts which eventually increased the Zn concentration in the stalks.…”

Field experiments were carried out on sandy soils of Karnal, Bawal and Balsamand of Haryana for (2018 to 2019) to study the effect of potassium application (0, 30, 60 and 90 kg K2O ha -1 ) on maize fodder (African Tall). The results revealed that maize crop responded to potassium application significantly up to 60 kg K2O ha -1 . The potassium application significantly increased maize straw yield and fresh yield. The K content and K uptake by maize crop increased with potassium fertilizer application to the soil.
