“…Fine ridges were prepared, maintaining suitable row-to-row (75 cm) and plant-to-plant distance (9 cm), whereas the plot size was 12 m 2 . The recommended seed rate of maize hybrid Pak-Afgoi (SG 2002, Chattha Seed Corporation, Pakistan), i.e., 75-100 kg ha -1 , was used in the experiment (Ayub et al, 2003). Plants were irrigated continuously during the complete growth period to maintain the optimum moisture level.…”

The hot climate is the major reason to promote salt salinization and sodication, which retards the crop productivity. The increase in salt-affected soils is adversely affecting worldwide productivity. The antagonistic effect among P and Zn causes nutrient deficiency and increases under saline conditions. The present study aimed to identify the targeted influence of foliar application of P and Zn on maize biometric and fodder quality parameters under saline-sodic conditions. The experiment was based on three P (0, 1, 2, 2.5%) and Zn levels (0, 1, and 1.5%), with three replications. The study showed that P concentration in maize was improved significantly with Z1P1 (51.0%) application, followed by Z0P2 (33.15%) and Z1.5P2.5 (28.0%). The Zn concentration enhanced with Z1P0 (91.73%), followed by Z0P1 (84.45%) and Z1.5P1 (84.18%). Nitrogen concentration improved with Z1.5P2.5 (39.84%). Total mineral contents were increased with Z1.5P2 (156.71%), followed by Z0P1 (142.64%) and Z0P2 (141.99%). Crude protein concentration was improved in Z1.5P1 (39.92%), followed by Z0P2 (11.92%). Crude fat percentage was increased with Z0P2.5 (51.89%), followed by Z0P1 (34.91%) as compared to Z0P0. The study concludes that foliar application of P and Zn in saline-sodic conditions helps retard the negative impacts of salts on biometric and quality parameters of maize fodder.

Fertilizer Phosphorus Solubility Effects on Indian Mustard–Maize and Wheat–Soybean Cropping Systems Productivity

et al. 2018

In Indian mustard and wheat, newly developed phosphorus fertilizers, Suphla of 20:20:0 grade with 60 and 80% water solubility were comparable with di‐ammonium phosphate for crop productivity. Residual effect of newly developed phosphorus fertilizers sources was significant in succeeding maize and soybean crops. All P sources were found equally effective and recorded higher yields and nutrient uptake compared to omission of P. Phosphorus fertilizer sources, Suphla of 20:20:0 grade with 60 and 80% water solubility can be used to meet out the P requirement of mustard–maize and wheat–soybean systems. Crop responses to P fertilization, in terms of productivity, phosphorus‐use efficiency (PUE), and residual fertility in soil, can depend on the form of P applied. A field experiment was conducted to determine the effect of various P fertilizer forms on productivity and PUE indices in two predominantly practiced Indian mustard [Brassica juncea (L.) Czern & Coss.]–maize [Zea mays (L.)] and wheat [Triticum aestivum (L.) emend. Flori & Paol]–soybean [Glycine max (L.) Merrill] cropping rotations. The experiment was conducted during 2012–2014 at the Indian Agricultural Research Institute, New Delhi, India. A ‘Suphala’ P fertilizer, with 30, 60, and 80% water solubility was compared with single superphosphate (SSP) and di‐ammonium phosphate (DAP), all including the recommended dose of N and K through urea and muriate of potash. The seed yield (6.0—21.3%), crop equivalent yield (4.7–10.3%) and system net returns (1.8–11.8%) of Indian mustard were higher with direct application of SSP over other soluble and partially soluble P fertilizers. Wheat yield (4.6–9.6%) and system net returns (2.7–9.6%), were higher using DAP. However, the residual effect of P fertilizers exerted a significant influence on the performance of succeeding maize and soybean crops. Using DAP as P fertilizer form recorded higher grain yield and system net returns of maize and soybean than other soluble P forms. Irrespective of the fertilizer form, treatments involving P application improved P use indices, and apparent N and K recovery in Indian mustard and wheat crops. Hence, the studied P fertilizer forms will result in higher productivity, sustainable use of resources and reduction in production costs for these cropping systems.
