Field experiment was conducted during 2006-2007 to study the effect of phosphorus management in greengram-safflower sequence in a Vertisol. The twelve treatments and three replications designed in RBD consisted of 100% RDF (20:40:20 NPK kg/ ha to greengram and 25:25:25 NPK kg/ ha to safflower), 50% recommended P, No P, 50% recommended P + PSB (25 g/ kg seed), 5 t FYM/ ha, 5 t FYM/ ha + PSB applied in various combinations to greengram in <italic>kharif</italic> and safflower in <italic>rabi</italic> season. The results indicated that application of 100 % recommended P along with recommended N and K significantly enhanced the yield of greengram and safflower. However, these results were comparable with application of 50 % P (20 kg/ ha to greengram and 12.5 kg/ ha to safflower) + PSB along with recommended dose of N (20 kg/ ha to greengram and 25 kg/ ha to safflower) and K (20 kg/ ha to greengram and 25 kg/ ha to safflower) to greengram and safflower in crop productivity with higher nutrient uptake and apparent nutrient balance. The higher P use efficiency was observed with the application of 50 % recommended P to both the crops alongwith PSB.

System productivity, nutrient uptake and apparent nutrient balance in the wheatmungbean- T. aman rice cropping system was studied. The experiment comprised four treatments-absolute nutrient control (T1); farmer’s practice (T2); AEZ basis fertilizer application (T3) and soil test basis fertlizer application (T4). The treatments were compared in a RCBD with three replications over two consecutive years, 2008-09 and 2009-10. The experiment was conducted in Chhiata clay loam soil. The average yields of wheat, mungbean and T. aman ranged from 1415 to 3096 kg ha-1, 1020 to 1463 kg ha-1 and 2999 to 4282 kg ha- 1, respectively showing T4 as the best treatment. The same treatment (T4) demonstrated the highest nutrient uptake by the crops. The apparent balance of N and K (difference between nutrient uptake and nutrient addition) was negative; however it was less negative for T4 treatment. The P balance was positive for all the treatment except T1. Positive S balance was observed in T3 and T4 but negative in absolute control and farmer’s practice. Zinc and B balance was also positive in case of T3 and T4, but negative for T1 and T2 except B. The study suggests soil test basis fertlizer recommendation for the wheatmungbean- T. aman rice cropping system.Bangladesh J. Agril. Res. 42(3): 509-520, September 2017

Phosphorus (P) deficiency is one of the serious problems affecting plant growth in mungbean in different parts of the world. The root, shoot and biomass related traits were investigated for identifying P-efficient genotypes in 54 mungbean genotypes under low-P (LP) and normal-P (NP) conditions. In this study, the membership function value of P use efficiency of studied traits was used as a compendious index for studying P use efficiency (PUE) in mungbean. Among the studied traits, mean values of total root volume, chlorophyll concentration, root dry weight (RDW) and root to shoot ratio increased >25% under LP condition indicating that these traits are highly responsive to P deficiency. Correlation and stepwise regression analysis revealed that RDW explained most of the variation and could be used as a clear indicator of PUE. The five highly P-efficient genotypes namely, MH 805, M 42, PUSA 9531, EC 398885 and M 209 with high MFVP values may be used for PUE improvement in mungbean.

Nutrient Uptake Efficiency

The scarcity of water in the Mediterranean area has frequently led to the use of saline water for irrigation. Container grown ornamental production has relatively high rates of water and nutrient loss from fertigation. A better understanding of water and nutrient use efficiency with water that has elevated levels of saline could reduce runoff water and its environmental impact. Fern leaf lavender (Lavandula multifida) plants were grown for 8 weeks in plastic containers with a sphagnum peatmoss and perlite substrate (80:20 by volume) to evaluate the effect of saline water [2.0 (T1 or control), 4.5 (T2), or 7.5 (T3) dS·m−1] on water and nutrient uptake efficiency. Leachate was collected to determine runoff volume and composition which included nitrate-nitrogen (NO3−-N), phosphate-phosphorus (PO42−-P), and potassium (K+) concentration. Plant dry weight (DW) and nutrient content were determined in plants at the beginning and at the end of the experiment to establish the nutrient balance. Increasing salinity levels of irrigation water did not significantly reduce either the plant DW or the water use efficiency (WUE). Based on nutrient balance, the increasing salinity (2.0 to 7.5 dS·m−1) affected the plant nutrient uptake efficiency, which decreased 28% for N, increased 26% for P from the lowest to highest sodium chloride levels; whereas K did not show a clear trend. Nutrient runoff increased (28% N, 9% P, and 27% K) to the environment from the lowest to highest sodium chloride levels.

Aim: The present study was conducted to investigate the effect of combined application of rock phosphate with water soluble phosphorus fertilizers on its efficiency in relation to soil and crop production. Methodology: Rock phosphate and single super phosphate were used as supplemental source of phosphorus and applied in variable combinations at graded doses, with maize and groundnut as test crop. Lime was applied in combination with 100% SSP to analyse its effect. The composite surface (0-15 cm) soil samples were collected at critical growth stages of maize and groundnut and further analyzed for different physical and physico-chemical characteristics. The plant samples were collected from each treatment at harvest stage for nutrient analyses. Results: Application of rock Phosphate increased the available phosphorus in soil. The combined treatment significantly influenced the yield attributes and nutrient uptake of both maize and groundnut crops. Among the combination, equal proportion of soluble single super phosphate and insoluble rock phosphate source of P outreached the other combination ratios. The highest agronomic phosphorus use efficiency and relative agronomic efficiency of the cropping sequence was obtained with the combined treatment of Single super phosphate along with lime. Interpretation: Combination of rock phosphate which has been reported to be farmer’s pocket friendly along with single super phosphate under acid soil conditions holds the potential to produce better results as compared to use of lone conventional water soluble phosphatic fertilizer like single super phosphate.

Fertilization with high levels of phosphorus increases the risk of environmental pollution. Identification of critical values of P in soil (SOP) and in plant tissues (PiP) is essential for achieving the maximum wheat yield without P loss. The critical value is the value of P which gives the optimum yield; the response of crop yield to P fertilization above this value is not predictable or nil. Here, a 4-year field experiment was conducted to identify the SOP and PiP for achieving maximum yield of bread wheat using 11 rates of P fertilization (0, 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 kg P2O5 ha−1). The linear–linear and Mitscherlich exponential models were employed to estimate the PiP and SOP. The degree of phosphorus saturation (DPS) was used to assess the potential environmental risk; furthermore, phosphorus use efficiency (PUE) was also calculated under the studied fertilization levels. Phosphorus in soil and wheat plant was affected by the application rates and growing seasons. Increasing P fertilization rates led to gradual increases in soil and plant P. The SOP ranged between 21 and 32 mg kg−1, while the PiP ranged between 6.40 and 7.49 g kg−1. The critical values of P calculated from the Mitscherlich exponential models were 20% higher than those calculated from the linear–linear models. Adding levels of P fertilization ≥90 kg P2O5 ha−1 leads to higher potentials of P runoff and leaching, in addition, PUE decreased sharply under high P fertilization levels. The response of wheat yield to P fertilization in sandy calcareous soil is predictable below Olsen P values of 21 mg kg−1. Identification of critical P values for wheat production is of great importance to help policy makers improve P use efficiency and attain optimum wheat yield under eco-friendly environmental conditions by eliminating the accumulation of excess P fertilizers in soil and water.
