Effect of Composted Rock Phosphate with Organic Materials on Yield and Phosphorus Uptake of Berseem and Maize

Abstract

Field experiments were conducted to determine the effect of composts prepared from different organic materials with rock phosphate (RP) on yield and P uptake of berseem and their residual effect on maize crop (cv. Azam) during 2011-2012. Composts prepared from RP fed farm yard manure (FYM), simple FYM, organic waste and city garbage were applied at the rate based on their P concentrations. Composts significantly (P ≤ 0.05) increased total dry matter weight of Berseem in first and second cut over control. Residual effect of the prepared composts was determined on yield and plant P uptake of maize in the same layout of Berseem. Maximum and significantly (P ≤ 0.05) higher maize grain yield, total dry matter yield and stover yield of 3161 kg•ha −1 , 9633 kg•ha −1 and 6472 kg•ha −1 , respectively were recorded by the residual effect of compost of organic waste with half dose of SSP. Thousand grains weight of 220 g was noted in the treatment of residual effect of compost of RP fed FYM with half dose of SSP. Post harvest soil N and P concentrations improved with composting. Significant (P ≤ 0.05) increases in N and P uptake by berseem and maize plants were observed with added composts. Results suggest that the use of composts prepared from different organic materials with RP is environmental friendly and has potential to improve crops yield and plants N and P uptakes for a prolonged time.

Effect of Composted Rock Phosphate with Organic Materials on Yield, Nutrient Uptake and Soil Fertility after Harvest of Maize (Zea mays L.)

“…It is well documented that P uptake by crop largely depends on dry matter accumulation and concentration of P in plant parts at cellular level and increased availability of P in the soil due to solubilization of added phosphorus by P solubilizers through production of organic acids. These results are similar to findings of Ali et al, (2014) who reported that nutrients accumulation in plant were enhanced by the use of RP composted and inorganic materials. Erdal et al, (2000) also reported that accumulation increased in plant N and P when dung as organic material and chemical fertilizer was applied.…”

“…Most of the simple cationic forms of nutrients present in the soil at any time are in exchangeable forms associated with clay minerals and the organic fractions of the soil, of which these can be rapidly exchanged with cations in the soil solution. These results are collaborated with findings of Ali et al, (2014) who reported that composted rock phosphate with organic material significantly increased the content of nutrients in soil.…”

Combined Effect of Enriched Compost and Microbial Inoculants on Soil Nutrients and Phosphorus uptake by Rice

“…Mycorrhiza which chiefly act as the nutrient mobilizers due to extension of plant roots also helps in nutrient solubilisation to some extent. These results corroborate with findings of Ali et al, (2014) who reported that composted rock phosphate with organic material significantly increased the content of nutrients in soil (Fig. 3).…”

Effect of organic farming practices on soil and performance of soybean (Glycine max) under semi-arid tropical conditions in Central India

“…The higher yield was attributed to the higher organic carbon (Walker et al, 2004) and available macronutrients viz., N, P and K. Organic farming practice involves judicious application of nutrient which improved the productivity (Sushila and Giri, 2000). Significant increase in the yield of maize (Ali et al 2014;Bekeko, 2014), rice (Tedesse et al 2013) and wheat (Saini and Kumar, 2014) with the application of organic nutrients has already been reported.…”
