Tillage influences soil quality via its effects on soil physical, chemical, and biological properties, which in turn affect crop productivity. This study evaluates the effects of conventional (CT) and no-till (NT) systems on (1) soil temperature, bulk density, soil gravimetric water content (GWC), saturated hydraulic conductivity (Ksat), soil organic carbon content (SOC), and total nitrogen (N), and (2) growth and yield of 3 sweet potato (Ipomoea batatas) (L) Lam varieties (87/00/87, ex-Igbariam, and 8164). A field experiment was conducted in 2005 and 2006 on a Typic paleudult in south-eastern Nigeria. The experimental plots comprised 6 treatments (CT 87/00/87 variety, CT ex-Igbariam, CT 8164, NT 87/00/87 variety, NT ex-Igbariam, NT 8164 variety) laid out in the field using randomised complete block design replicated 3 times. Soil temperature was 1–2°C higher in CT plots during early stages of crop development. CT plots had significantly lower soil dry bulk density (1.30–1.35 Mg/m3) than NT plots. Soil GWC was higher, whereas Ksat was lower, in NT plots than CT plots at 35 and 65 days after planting (DAP) for both planting seasons. NT plots had a 0.22–0.26-fold increase in SOC and 16–27% higher N content compared with CT plots at 35 and 65 DAP. The 3 varieties of sweet potato used did not significantly influence soil properties at the different times after planting. Sweet potato yield obtained in CT 87/00/87 variety (21.7–24.9 Mg/ha) for both seasons was higher (P < 0.05) than sweet potato tuber yield obtained from NT ex-Igbariam plots (which had the lowest yield) by about 88%. For each variety, CT plots has significantly higher yield than NT plots. This study showed that although NT practices conserved soil moisture, decreased soil temperature, reduced water infiltration, and increased SOC and soil total N content when compared to CT plots, the reduction in soil compaction at the early stages of crop development (0–65 DAP) in CT plots had a more positive impact on tuber yield and masked the positive effect of other soil productivity parameters for this crop.

Integrated Nutrient Management

This experiment was conducted in the farmer’s field at Khajrauta, Gadhawa-4, Dang, Nepal to evaluate the effect of integrated nutrient management on growth and yield of cauliflower as well as their residual effects on soil properties. The cauliflower variety silvercup-60 was grown under eight different treatments; T1: 50% N through RDF + 50% N through FYM; T2: 50% N through RDF + 50% N through PM; T3: 50% N through RDF + 50% N through VC, T4: 50% N through RDF + 25% N through FYM + 25% N through PM; T5: 50% N through RDF + 25% N through VC + 25% N through PM; T6: 50% N through RDF + 25% N through VC + 25% N through FYM; T7: 50% N through RDF + 25% N through  VC +25% N through FYM; T8: 50% N through RDF + 50% N  through FYM,VC and poultry manure. The experiment was laid out in RCB design with three replications. The result revealed that the  highest plant height (36.40 cm), number of leaves (15), plant spread (31.72 cm), leaf area (526.5 cm2), curd weight (207.3g) and curd yield (12.85 t/ha) were found under 50% N through RDF +50% N through VC. The root length, root diameter and root density were better under all INM treatments as compared to 100% N through RDF. INM treatments showed lesser bulk density, lesser particle density, greater infiltration rate and greater organic matter content than application of 100% N through RDF. Soil total nitrogen was increased in all INM treatments while soil available phosphorus decreases in all treatments except 100% N trough RDF and 50% N through RDF +50% N through PM. Thus, farmers are suggested to apply 50% N through VC along with 50% N through RDF to increase cauliflower yield.

AbstractBiochar has a low chemical composition and is recalcitrant to degradation. For good soil fertility and nutrient use efficiency of crops it becomes imperative that addition of a fast releasing nutrient source to biochar be sought. Therefore, studies were conducted in 2017 and 2018 to evaluate the effects of biochar with poultry manure (PM) and NPK fertilizer on soil properties, growth and yield of ginger. Treatments evaluated were: biochar applied alone at 15 t ha-1 , PM applied alone at 15 t ha-1, NPK fertilizer applied alone at 200 kg ha-1, biochar applied at 15 t ha-1 with poultry manure applied at 15 t ha-1 (B+PM), biochar applied at 15 t ha-1 with NPK fertilizer applied at 200 kg ha-1 (B+NPK) and a control with no amendment whatsoever. The experimental design was a randomized complete block design with three replications. Biochar, PM, NPK fertilizer alone or B+PM and B+NPK improved soil physical and chemical properties, growth and yield of ginger compared to no amendment (control). NPK fertilizer did not improve soil physical properties nor increased pH, OM, Ca and Mg significantly. B+PM and B+NPK improved soil physical and chemical properties, growth and ginger yield compared to their sole forms. Although B+PM had better soil physical properties, B+NPK increased yield and growth of ginger compared to B+PM. B+NPK increased the yield of ginger by 12.2% and 10.6% in 2017 and 2018, respectively compared with B+PM. B+NPK also increased the yield of ginger by 49.2% and 50.3% in 2017 and 2018, respectively compared to biochar alone. This was related to high presence of nutrients in B+NPK especially N and K which are important for ginger rhizome formation.
