High temperature stress at reproductive stages of cotton crop severely affects the yield and quality of cotton crop under changing climatic conditions. To alleviate the adverse effects of high temperature stress on cotton crop, the regulatory effects of potassium (K), zinc (Zn), and boron (B) were assessed by applying different temperature regimes at three reproductive stages of cotton crop under field and glass house conditions.

The Treatments consists of 2 levels of Potassium viz. K1(40 kg K2O/ha), K1(50 kg K2O/ha) and 4 levels of Iron viz.10 and 20 kg/ha as basal and 0.1 and 0.2% as foliar application. There were 9 treatments each being replicated thrice and laid out in Randomized Block Design. The results revealed that treatment T8 (50kgs potassium + 0.2% iron) recorded maximum Dry weight, Number of cobs per plant, cob length, cob girth , cob weight without husk, cob yield without husk, Green fodder and B: C ratio.

The experiment comprising nine treatment combinations were laid out in randomized block design and replicated thrice. The treatment consisted combination of 3 levels of nitrogen viz. 75kg/ha, 60 kg/ha and 45 kg/ha, and 3 levels of potassium viz. 20 kg/ha, 30 kg/ha and 40 kg/ha along with Phosphorus at 40 kg/ha. The Yield parameters viz. Number of Heads/hill, Number of Grains/head, Grain yield, and maximum Gross return, Net return and B:C ratio were recorded with the application of 75 kg/ha Nitrogen + 40 kg/ha Phosphorus + 40 kg/ha Potassium.

Research information on response of crops to phosphorus and potassium levels generated very scanty and as such generating further information is very much essential specially in low phosphorus and potassium containing soils to combat the present situation. With this in view, the present study was initiated in low phosphorus and potassium soils to assess the effect of phosphorus and potassium levels on growth, yield and economics of finger millet in Alfisols of Ramanagara district of Karnataka.

After nitrogen, phosphorus and potassium, sulphur is the fourth nutrient, whose deficiency is widespread in India. Sulphur deficiency is observed primarily due to high crop yield and therefore higher rate of sulphur removal by crops, and lesser use of sulphur-containing fertilizers. Boron foliar sprays seemed to overcome the deleterious effects of drought by overcoming the drought-related molecular responses and consequently appeared to meliorate sunflower growth under insufficient water conditions.

Agricultural production continues to be constrained by a number of biotic and abiotic factors that can reduce crop yield quantity and quality. Potassium (K) is an essential nutrient that affects most of the physiological processes that influence plant growth. To understand the effect of potassium, a pot culture experiment was carried out with graded levels of potassium to study the influence of potassium on physiological parameters of maize in black calcareous and non-calcareous soils.
