Abstract
A field experiment was conducted during kharif season with randomized block design allocating 13 fertilizers levels with three replications on pearl millet and observations were taken of light interception and photosynthesis pearl millet crop under rainfed conditions. The photosynthetically active radiation, photosynthesis, leaf conductance and transpiration were measured in all the treatments. Solar radiation trapped by chlorophyll in the process of photosynthesis provides the substances for growth and yielded more in T13 (60 kg N+30 kg P2O5+20 kg K2O/ha) as compared to other treatments. In control treatments as stomatal conductance was minimum 181 m mol m-1s-1 in T1 (control). The per cent absorbed photosynthetically active radiation (PAR) was higher at 45 days after sowing in all the treatments and reverse trend was observed in case of transmitted PAR and maximum in treatment T13 (284 m mol m-2s-1). Similar trends were observed in transpiration rate, water use efficiency deferred in fertility levels, but it was not significant except at 30 days after sowing.
