ThesisItem Open Access EVALUATION OF INDIGENOUS MATERIALS AS PROTECTANTS OF PIGEON PEA AGAINST PULSE BEETLE(Birsa Agricultural University, 1988) SINGH, DEVI DAYAL; CHAND, PREMA potted plant experiment was conducted in soils. collected from eighteen different locations of Ranchi district of Bihar using moong as a test crop to study (1) the response of legumes to P application (11) the suitability of different chemical extract ants for prediction of P requirements of legumes. Results indicated significant response of moong crop to fertilizer phosphorus. Higher response was observed at higher dose of phosphorus (60 ppm P) in comparison to a lower dose (30 ppm P). Correlation coefficients were worked out between available P determined by different chemical extract ants and dry matter yield as well as P uptake. The Olsen and Bray P₁ extract ants were found to be superior to other extract ants. Results also indicated that available phosphorus in these soils increased with a rise in soil pH and organic carbon content. Correlation study between inorganic P fractions and available P estimated by Olsen & Bray P, method indicated that Al-bound 1 phosphorus contributed more in P nutrition of moong followed by solid bound and Fe-bound phosphorus.
