Co-Application of Farmyard Manure and Gypsum Improves Yield and Quality of Peanut (Arachis hypogaea) under Rainfed Conditions

Abstract

Peanut (Arachis hypogaea L.) is the common cash crop of the rainfed areas. Appropriate management practices are very important to get better yield of peanut in sandy loam soil. A field study was carried out during the growing seasons of 2018 and 2019 to evaluate the effect of poultry manure (PM) (37.1 t ha-1), farmyard manure (FYM) (49.4 t ha-1), gypsum (GYP) (2.5 t ha-1), liquid humic acid (HA) (49.4 L ha-1) and co-application of GYP (1.2 t ha-1) and FYM (24.7 t ha-1) on peanut yield, quality and soil physical properties. Application of FYM, PM, HA and GYP (alone or in combination) significantly improved peanut yield, quality and soil physical properties. The combined application of GYP and FYM proved most effective (P ≤ 0.05) in improving the peanut yield (no. of pods per plant, 100 seed weight etc), quality (crude protein and oil content) and soil physical properties (moisture percentage, infiltration rate and bulk density). The combined application of GYP and FYM increased the pods yield by 67 and 65% during 2018 and 2019, respectively than control. Crude proteins (21%) and oil contents (9.0%) were also substantially increased in the combined application. Moreover, the combined application of GYP and FYM significantly retained the soil moisture and reduced bulk density of soil. Present findings suggest that integrated use of FYM and GYP under field conditions could improve the crop productivity, crude protein, oil contents, moisture percentage, and reduce the bulk density of soil thus improving overall soil health. © 2021 Friends Science Publishers

“…This is in accordance with Sulaiman and Mohammed 24 , who stated that application organic and NPK fertilizers increased the sweetness level of grapes. Likewise, Latif et al 13 reported that, the combined application of gypsum and compost increased pod yield by 67 and 65% during 2018 and 2019, respectively compared to the controls. Crude protein of 21% and oil content of 9.0% also increased substantially in the combined application.…”

“…Based on the report by El-Negar and Mohamed 12 , cow manure contains the mineral N. This process depends on the type of manure and its nutrient content, soil temperature and humidity among other factors. The chicken manure contains N (6.99-7.78%), P (0.89-099%), K (4.88-5.70%), organic matter (37.80-38.09%), bulk density (0.39-0.86%) and total porosity (31.00-60.40%), while the mineral nutrient content of compost (agricultural waste) contains N (0.51-0.53%), P (0.21-0.23%) and K (0.60-0.65%) 13 .…”

Improving the Quality of Functional Food Crops and Land Efficiency by Intercropping System on Application of Integrated Fertilizer

“…Cow manure includes the mineral N [20]. In contrast to compost (agricultural waste), which has N, P, and K content of 0.51-0.53%, 0.21-0.23%, and 0.60-0.65%, respectively, as its mineral nutrients, chicken manure contains 6.99-7.78% N, 0.89-099% P, 4.88-5.70% K, 37.80-38.09% organic matter, 0.39-0.86% bulk density, and 31.00-60.40% total porosity [21]. Based on the report of Nguyen et al [22], adding compost + mulch or compost alone can increase available water and air exchange tomato cultivation, whereas Abouziena and Haggag [23] reported that straw mulch was consistent in controlling weeds and had an effect on soil chemicals properties and had a low effect on apple fruit yield.…”
