Influence of soil calcium carbonate on yield and quality of Nagpur mandarin
This article examines the macronutrient status and quality of 11-14 years old of five Nagpur mandarin orchards of Saoner tahsils, Nagpur district as influenced by soil calcium carbonate. Calcareous soils (pH 7.41 to 8.38) with high free CaCO3 content (3.13 to 15.48%) indicating that these soils are moderate to high calcareous in nature and it adversely affects the availability of macronutrients and yield of Nagpur...

Additive main effects and multiplicative interaction (AMMI) and GGE-biplot analysis of genotype × environment interactions for grain yield in bread wheat (Triticum aestivum L.)
The combine ANOVA analysis for grain yield of 10 wheat genotypes at 12 environments showed that bread wheat grain yields were significantly affected by E (environment), which explained 75.01% of the total treatment (G+E+GEI) variation, whereas the G (Genotype) and GEI were significant and accounted for 9.48 and 15.5% respectively. Additive main effects and multiplicative interaction (AMMI) analysis indicated that three...

Technical and economic feasibility of biodiesel production by family farmers
The study aims to assess the economic feasibility of biodiesel production in association with others by family farmers in the town of Corbélia/PR. Biodiesel is presented as a partial alternative to socio-economic and environmental oil or total replacement of diesel oil, thus requiring studies on its economic viability. The work was developed through a case study to verify the economic feasibility of installing a...

Soil properties of a fallow field under long-term cultivation and fertilization regimes in Northern Guinea Savanna, Nigeria
The long-term dung (D), Nitrogen (N), Phosphorus (P) and Potassium (K) commonly referred to DNPK experiments in northern guinea savannah of Nigeria was subjected to different fertilization regimes from 1950 to 1996 under continuous cultivation. Experimental plots have been under fallow from 1997 till now. Surface soils (0 to 5 and 5 to15 cm) were sampled and analyzed for physical and chemical properties under different...

Studies on genetic diversity in Snake Gourd (Trichosanthes anguina L.)
Genetic diversity among 50 genotypes was worked out using Mahalanobis D2 statistic. Based on D2 analysis, the genotypes were grouped into four different clusters, where the cluster I possessed higher number (32) of genotypes followed by the cluster II (2), III (15) and IV (1). Clustering pattern revealed that geographical diversity was not associated with genetic diversity that is, genotypes collected from same location...

Effect of processing method on the quality of palm kernel cake: Chemical composition and nutrient utilization in enzyme supplemented diets
The feed value of palm kernel cake (PKC) from two expeller sites and two hydrothermal production facilities were assessed using 30 laboratory rats as a model. Following chemical analysis, the PKC were incorporated at 0% (control, CON) or 35% (w/w) into isonitrogenous maize-based diets (2.9% N, DM basis) and fed to individually caged albino rats for 28 days (n=6). All PKC diets included 0.5% (w/w) Alzyme Vegpro (Alltech...

Antifeeding and insecticidal effects of Capparis spinosa L. on Spodoptera littoralis (Boisduval) larvae
Insect pest management is facing the economic and ecological challenge worldwide due to the human and environmental hazards caused by the synthetic pesticide chemicals majority. A search for an alternate technique for the insect pests’ management arises in recent years. The present study was carried out under laboratory conditions, to evaluate the potential of Capparis spinosa L. as control agents...
