Potassium concentrations in irrigation waters varied greatly across different locations in India (spatial), different times of the year (temporal), and different sources of irrigation used.
West Bengal soils, thought to be rich in K, showed a significant increase in grain yield of rice and wheat with K addition over the existing fertilisation practice.
On-farm and on-station trials showed that balanced fertilisation (i. e. , applying the right rates of N, P, K, S, Zn, B, and Ca) helped in maximising groundnut yield, nutrient uptake, and farmer profi ...
On-farm experiments conducted at 60 locations in northern India demonstrated that yields and profits for rice and wheat increased significantly with a combined application of K, S and Zn along with fa ...
Emerging data from on-farm and on-station experiments in the rice-maize systems in India and Bangladesh have revealed very high system productivity and high responses of maize and rice to applied K.
A review of the published literature showed variable K response in oilseeds and pulses across India. Economic calculations, using current prices of crop commodities and potash fertiliser, revealed sig ...
Potassium application led to increases in tuber yield, plant growth characteristics, tuber quality, K uptake and maintenance of available K in soil under cassava.
Potassium input-output balances in different states of India were estimated and mapped using the IPNI NuGIS approach. Results showed negative K balances in most of the states suggesting deficit K appl ...
