Abstract Mangrove is a renewable resource that provides services related to the environment, such as abrasion protection, seawater control of incursion, reduction sea wave height and speed, cleaning water contaminants, among others, important support living beings. Its objectives include study evaluate impact planting distance from beach which useful for increasing growth mangrove ecosystem typ...

The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...

Restoration has been elevated as an important strategy to reverse the decline of coastal wetlands worldwide. Current practice in restoration science emphasizes minimizing competition between out-planted propagules to maximize planting success. This paradigm persists despite the fact that foundational theory in ecology demonstrates that positive species interactions are key to organism success u...

On global scale, community participation in various activities is the core in the quest for sustainable development and environmental protection related issues. Community involvement in tree planting in Kenya is as old as modern agroforestry that started in 1971. However, certain biophysical environmental factors have not worked against the concept of community participation in tree planting. A...

Experiments were conducted at the CSIR-Crops Research Experimental station at Kumasi, Ghana, to determine the effects of seed sorting and planting device on yield of maize in the 2014 major growing season. Two jab planters were used to plant sorted and unsorted seeds. The control treatment was cutlass planting of unsorted seed. One of the jab planters was imported from China; and the other was ...

Eggs of Meloidogyne arenaria race 1 were encapsulated in calcium alginate for use as inoculum to infest peanut field plots. Some eggs within the capsules remained viable up to 10 weeks after preparation. A field site was successfully infested at peanut planting and (or) 6 weeks later. Dual applications of nematode inoculum (at planting and 6 weeks later) were superior to single applications (at...

This experiment was conducted at Azad University experiment station to evaluate the effects of planting date and time of nitrogen application on yield and sugar content of sweet sorghum in 2003. Four planting dates (May 4, March 19, June 3 and June 18) and three stages of nitrogen application (3-5/8 leaf stage, boot stage and soft dough stage) were assigned to the main and subplots, respectivel...

Microplot experiments were conducted to evaluate the effects of inoculum level and time of application of Paecilomyces lilacinus on the protection of tomato against MeIoidogyne incognita. The best protection against M. incognita was attained with 10 and 20 g of fungus-infested wheat kernels per microplot which resulted in a threefold and fourfold increase in tomato yield, respectively, compared...

In 1984-85 metham-sodium and the combination of 1,3-dichloropropene plus aldicarb decreased (P = 0.05) soil population densities of Pratylenchus penetrans at planting, midseason, and at harvest relative to the untreated control. These treatments increased (P = 0.05) marketable potato tuber yield from 27% to 46% in 1984 and from 23% to 37% in 1985, as compared with the control. In 1984 oxamyl (1...

Knowledge about fungi diversity following different planting patterns could improve our understanding of soil processes and thus help us to develop sustainable management strategies. The objective of this study was to determine the impact of different furrow-ridge mulching techniques on fungal diversity in rhizosphere soil under continuous cropping system. The investigated treatments were: flat...
