Abstract
A field experiment was conducted during 1991-93 at Hyderabad to study the effect of P in rice-sunflower-greengram cropping system in sandy loam soil with moderate available P. The number of tillers and panicles/m2, filled grainstpanicle and test weight of rice significantly increased up to 60 kg P20dha. The mean rice grain yield increased by 1,082 kglha over control (without P). The yield of sunflower in succeeding rabisignificantly improved by residual P applied at 60 kg P205/ha to preceding rice and the direct effect of 60 kg P205/ha to sunflower. The mean seed yield of sunflower increased from 1,156 kgtha in control to 1,611 kg/ ha with direct application of 60 kg P20dha. The mean sunflower yield increased significantly due to the cumulative effect of 60-60 kg P,05/ha to rice in kharif and sunflower in rabi. The cumulative effect of P through 60-60 kg P205/ha to rice- sunflower also increased the mean grain yield of greengram to 912 kglha in the following summer season compared to 692 kglha through residual effect of 60 kg P205/ha only to rice and 707 kgtha through residual effect of 60 kg P205/ha only to sunflower. However, the rice grain equaivalent yield of 11,546 kglhdyear was obtained with application of 60 kg P20dha both to rice and sunflower, being on par with 60 kg P205/ha to rice in kharif and 30 kg P205/ha to sunflower in rabi. Thus there was a saving of 30 kg P205/hdyear.
