“…Data in Table (5) show that N, P and K in both foliage and tuber were not affected by the source of phosphorus in both seasons. These results are in agreement with those reported by Mishra et al (1981).…”

“…This superiorty might be due to that mixing farmyard manure with rock phosphate substantially enhanced dissolution of rock phosphate in the soil through the action of microorganisms which can play an important role in releasing phosphorus and other nutrients from rock phosphate and consequently increased the average of tuber weight and total tubers yield (Hauka et al, 1990 andEl-Nagar, 1999). Similar results were reported by Mishra et al (1981); Dass et al, (1991) and Singh et al (1996). Percentage of tuber dry weight and tuber starch content were not affected by the interaction between phosphorus sources and other treatments in both seasons of 1997 and 1998.…”

“…Data in Table ( 4) indicate that average of tuber weight increased significantly by application of rock phosphate in the two seasons, this increasing resulted as a reflection of increasing of plant growth. On the other hand, total tubers yield / fed., tuber dry weight (%) and tuber starch content were not affected by the source of phosphorus, these results agreed with Mishra et al (1981), Sud and Negi (1991) and Hellums et al (1992), who found insignificant differences between rock phosphate and super phosphate on dry matter of tuber and total tubers yield.…”

“…plant height, number of main stems / plant and fresh and dry weight / plant as well as total tuber yield and tuber dry weight. Mishra et al (1981) reported that tubers yield, tuber dry matter content, N, P and K contents in the crop (tuber + shoots) were not affected by phosphorus source (rock phosphate or superphosphate), and they found that mixture of rock phosphate and pyrites was more effective than superphosphate on tubers yield, and the results indicated that mixing rock phosphate with pyrites substantially enhanced dissolution of rock phosphate in soil through the actions of H2SO4 in oxidation.…”

Two field experiments were carried out at El-Zahraa, Belqas, Dakahlia Governorate, Egypt, during the two summer seasons of 1997 and 1998 on potato cv. Diamant to evaluate the effect of rock phosphate application as a natural source of P in comparison with single super-phosphate (75 kg P2O5 for both sources) and four sources of fertilizers, i.e. farmyard manure, livestock manure, poultry manure and mineral fertilization in addition to their interactions on vegetative growth, tubers quality, total tuber yield and the concentrations of N, P and K (%) in both foliage and tubers.Results indicated that application with rock phosphate increased significantly both fresh and dry weight of foliage plant in the first season and average of tuber weight in both seasons. On the other hand, plant height, number of main stems / plant, total tuber yield ton/fed., tuber dry matter, starch content in tuber, content of N, P and K in foliage and tuber in both seasons were not affected by phosphorus sources (rock or super-phosphate).Mineral fertilization increased significantly plant height, tuber dry matter, content, N and K content in foliage in both seasons, while application of farmyard manure increased average of tuber weight in both seasons. Results also indicated that applying either farmyard manure or mineral fertilization increased significantly the total tuber yield in both seasons. The interaction between rock phosphate and farmyard manure increased total tuber yield and average tuber weight in both seasons.Generally, using rock phosphate, or super phosphate together with farmyard manure at the rate of 15 ton/fed. in addition to 180 Kg N + 96 kg P2O5/fed. increased total yield of tubers / fed., but economically application of rock phosphate would save a considerable amount of phosphate fertilizers and consequently would decrease the total costs/fed. as compared with super-phosphate fertilizer. In the meantime, the price of one ton of rock phosphate powder (Abo-Tartour rook 26-28.5% P2O5) evaluate between 90-110 L.E., whereas the price of one ton of super-phosphate is about 300 L.E. Moreover, application of rock phosphate together with organic manure may help in decreasing the pollution of environment.

“…The tuber yield obtained with MRP was only 5-9 t/ha, compared with 14-1 t/ha with SSP (Table 1). Mishra, Sharma & Mishra (1981) reported that MRP was only 48-8 % as effective as SSP for potato production in the sandy loam neutral soils of Pantnagar, U.P., India, when the fertilizers were compared at 52-5 kg P/ha. Likewise, in the wheat crop, grown on an acid soil (pH 5-6) of Palampur, H.P., India, MRP at 34-9 kg P/ha was found to be 44-8 % as effective as SSP at an equivalent rate of application of P (Marwaha, 1983).…”

A field experiment on an acid soil of Shillong, in 1982 and1983, investigated the comparative performance of Mussoorie rockphosphate (MRP), single superphosphate (SSP) and their combinations for potatoes. MRP, when applied alone, proved much inferior to SSP, on an equal P basis, in tuber characters, tuber yield and nutrients (N, P and K) uptake. Application of SSP together with MRP improved the efficiency of the latter. SSP and MRP combinations in 25:75, 50:50 and 75:25 proportions, on a P basis, were 79-3, 95-8 and 101-2% as effective as SSP in terms of tuber production. The response to P was optimum at 70 kg P/ha with SSP and was linear up to the highest rate (105 kg P/ha) with the combinations of SSP and MRP. Concentration of N in tubers declined with the increasing amounts of P, whereas P and K concentrations were little affected.
