Doses of cattle manure and levels of irrigation with wastewater in the cultivation of peppers

In areas with water scarcity, recycled water and cow manure in organic substrate makes the cultivation of peppers possible, supplying water and nutrition to pepper. The present research was conducted to evaluate the effect of cattle manure doses and levels of irrigation using wastewater on pepper cultivation (Capsicum frutescens L.). The treatments include: three replacement levels of wastewater treated, based on the...

Nutritional and fermentative quality of sugarcane (Saccharum officinarum) top ensiled with or without urea and molasses

This study was conducted to evaluate the effect of urea and molasses addition on physical properties, pH, temperature, dry matter loss and chemical composition of sugarcane top (SCT) silage. Treatments were arranged as 2*4 factorial, with two SCT types (green and burnt) and four silage treatment types (without additive, 4% molasses, 1% urea and 1% urea + 4% molasses) in a completely randomized design. Forages were...

Correlation of climatic factors between the development of tomato cultivars (Solanum lycopersicum L., Solanaceae) with adults of two key pests

The tomato (Solanum lycopersicum L., Solanaceae) is a crop has suffered from insect attacks and environmental factors. The objective of this work was to evaluate the correlations of climatic factors and two key pests at the development of cultivars. The study was conducted in Alagoas, Northeastern Brazil, monitored from September 2016 to August 2017. The experimental randomized with five treatments and twelve...

Cowpea nutrient responses for Malawi and Tanzania

Research was conducted in Malawi and Tanzania to determine cowpea (Vigna unguiculata L. Walp) grain yield responses to applied P and K, the agronomic and economic efficiency of nutrient application, and the importance of other nutrient deficiencies. Nine site-years of research were conducted. Cowpea did not respond to fertilizer P and K in Malawi. In Tanzania, the yield response to applied P was linear with 21 kg of...

Rainfed rice response to fertilizer in the Sudan Savanna of West Africa

In West Africa, rice (Oryza sativa L. and Oryza glaberrimaI Steud) production is not meeting current demand. Low yields are attributed to diverse biotic and abiotic constraints including nutrient deficiencies, inadequate agronomic practices, and socio-economic constraints. This study quantified yield and profit responses of rainfed rice produced in the Sudan Savanna of Burkina Faso and Mali to fertilizer N, P, K, and...
