Abstract: | Chickpea contains high levels of protein, vitamins and minerals. Acceptable chickpea yield is the result of meeting
nitrogen and phosphorus requirements. The effect of appropriately meeting such requirements reflects on growth
and can easily be evaluated using growth analysis. This research determined: (a) The effect of nitrogen and phosphorus fertilization on phenology, net assimilation rate, number of green leaves, leaf area, leaf area index and leaf
area duration; (b) Green chickpea yield and number of pods due to fertilization; and (c) The combination of
nitrogen and phosphorus fertilization that yields the most net revenue. Nitrogen and phosphorus fertilization
was evaluated; each at the doses of 0, 75 and 150 kg ha–1 (N0, N75, N150; P0, P75 and P150, respectively).
The combination of the levels of both nutrients generated nine combinations of treatments which were distributed in the field in a randomized complete block design in an arrangement of divided plots with four repetitions.
Timing of phenological phases were similar among treatments. Nitrogen and phosphorus fertilization increased
number of leaves, leaf area index, and leaf area duration that translated into increased green chickpea yield (GCY).
Combinations N150-P75 and N150-P150 produced the highest GCY. The highest net revenue and revenue per
peso invested was obtained with N150-P75. |
