Residual of the mixture of glyphosate and 2,4-d herbicides on yellow red latosol with soybean cultivation

The objective of this study was to evaluate the residual effect of glyphosate and 2.4-D herbicides in the initial development of the soy crop in a Yellow Red Latosol. The experiment was conducted in randomized design, consisting of 4 different doses of herbicides (0, 1, 2 and 5 times the recommended dose of the glyphosate and 2.4-D mixture), applied at intervals of 0, 3, 7 and 10 days before sowing, with 4 repetitions...

Effectiveness of three pesticides against carmine spider mite (Tetranychus cinnabarinus Boisduval) eggs on tomato in Botswana

The carmine spider mite (CSM; Tetranychus cinnabarinus Bois.) is one of the most destructive pests of vegetables, especially tomatoes. Its management in Botswana has, for years, relied on the use of pesticides. This study evaluated the efficacy of abamectin, methomyl and chlorfenapyr against CSM eggs under laboratory conditions in Botswana. Each treatment was replicated three times. The toxic effect was evaluated in the...

Response of maize (Zea mays L.) to foliar and soil applied fertilizers in the Semi-deciduous forest zone of Ghana

This experiment was conducted in 2019 major cropping season in the Semi-deciduous forest Agro-ecological zone of Ghana to solve low maize yield and improve maize productivity and enhance farmer’s income using foliar and soil applied fertilizers as nutrient sources. Eight treatments (T) were used; T1= {N, P2O5, K2O (90-60-60) kg/ha} at 2 and 6 weeks after sowing (WAS); T2= {Poultry manure (4 t/ha)} at 2 weeks...

Fruit and seed physiological quality changes during seed development and maturation in African eggplant (Solanum aethiopicum L.)

This work aimed at determining the optimum harvest time of African eggplant (Solanum aethiopicum L.) seeds, cv. Oforiwa and cv. Kpando for maximum physiological seed quality under tropical (TCC) and temperate oceanic climatic (TOC) conditions. Fruit morphological metrics such as fruit weight and size were also related to seed physiological quality. Seeds were harvested at different maturation stages from 20 to 82 days...
