Recent India Program Articles Published in Better Crops with Plant Food

North & West Zone
The Impact of Soil Test-Based Fertilization on Tomato By K.N. Tiwari, B.R. Gupta, R.K. Pathak, H.L. Sharma, and T.P. Tiwari
Current fertilizer use in tomato production in the central plain of Uttar Pradesh is generally confined to nitrogen (N) and phosphorus (P). This situation will not sustain tomato as an important cash crop system for northern India. A research and extension project has begun to effect positive change within the region.

Rebalancing Nutrient Application in Late-Sown Potato By B.R. Gupta, T.P. Tiwari, Rakesh Tiwari, and K.N. Tiwari
Common practice for cropping systems in the Gangetic Plain places a heavy reliance on soil nutrient reserves. Nutrient balances for most crops indicate significant depletion, especially for K. Potato provides one such example of a system in need of revitalization.

Diagnosing Potassium Deficiency and Maximizing Fruit Crop Productivity By K.N. Tiwari
The potassium (K) requirement of fruit crops is particularly high. In contrast, however, the use of K fertilizers in Indian agriculture/horticulture is negligible. Appearance of K deficiency symptoms in fruit crops of India is becoming a common field problem. This article will serve as a diagnostic tool for K management in fruit crops.

Site-Specific Nutrient Management in Mandarin Orchards By A.K. Srivastava, Shyam Singh, and K.N. Tiwari
Site-specific nutrient management (SSNM) can help tailor fertilizer applications for individual orchards and begin to address a more complex problem of wide variation in fruit yield within orchards.

East Zone
Balancing Potassium, Sulfur, and Magnesium for Tomato and Chili Grown on Red Lateritic Soil By P. Bose, D. Sanyal, and K. Majumdar
Potassium (K) improved yield and yield attributes in tomato and chili, as well as post-harvest quality...particularly at higher K rates. In both crops, use of potassium magnesium sulfate (K2SO4·2MgSO4) in conjunction with potassium chloride (KCl) proved superior to using KCl alone.

Spatial Variability in Available Nutrient Status in an Intensively Cultivated Village By: P.Sen, K. Majumdar, and Gavin Sulewski
Available nutrient status showed wide variation across the study area which was associated with fertilization history and the cropping sequence adopted by individual farmers.

South Zone
Sulfate of Potash Foliar Spray Effects on Yield, Quality, and Post-Harvest Life of Banana By A. Ramesh Kumar and N. Kumar
The benefits of applying foliar K included increased fruit bunch yields and enhanced physical and market quality traits. Foliar spray in the form of SOP could be economically integrated into banana nutrition strategies.

Site-Specific Nutrient Management for Maximization of Crop Yields in Northern Karnataka By D.P. Biradar, Y.R. Aladakatti, T.N. Rao, and K.N. Tiwari
On-farm rice, wheat, and chickpea demonstrations conducted across the region show substantial increases in yields and economic returns compared to recommended and common fertilization practices...which lead to stagnant and reduced food production.
