i) It is accepted that phosphorus should be applied in winter crop so that residual effect of P can be found in rainy season crop.

ii) For optimum nitrogen economy, organic manure should be added in rainy season crop so that it will be sufficiently decomposed and benefits the succeeding winter and spring season crops.

iii) Any inorganic fertilizer nutrient should be applied to the crop, which should maximize the response in cropping sequence. For example if potato based sequence is taken then potassic and phosphatic fertilizer should be added because potato is most responsive to potash and phosphorus.
