Plant density

Field experiments were carried out to evaluate the effects of four seed size (large, medium, small, and very small) and five plant populations (12.5, 25, 50, 100, and 150 plants m -2 ) on local faba bean yield and yield components. A split plot design with three replications was used, in which plant populations were assigned to main plots and

SUMMARY The change in the sowing date of maize modifies the response in grain yield to the plant density. The objective of this work was to study in the central region of Córdoba, Argentina, the effect of sowing date and plant density on the determi- nation of the yield and its components. The experiments were conducted in the field in

To derive optimal benefits from intercropping timber, farmers should make important initial decisions on tree species and planting density with a good understanding of their tradeoffs. Complex and data-intensive models used by researchers should be ...

A field study was conducted on the effect of four primary tillage implements and three seed densities on the grain yield of rain fed wheat (Tajan cultivar), using a drill planting machine with the end wheels. The experimental design was a split plot design in a 4×3 factorial with three replications. In this study, the main plots were the tillage treatments, namely Mouldboard plough, Disc Plough, Chisel Plough, Offset Disc, and sub-plots were seed rates of 350, 400 and 450 seeds.m-2. Determinations included grain yield and selected yield components. The results showed that grain yield was not affected by the densities of seed and tillage machine treatments. The use of Chisel Plough, with 400 seeds.m-2 sowing rate, had the highest grain yield of wheat grown in the Golestan province (Iran), a region with an average annual rainfall of 450 mm.

Summary 1. Increasing functional diversity often leads to an increase in ecosystem productivity in the form of overyielding. While the mechanisms (ie complementarity or facilitation) that underlie overyielding provide strong insights into species coexistence and community assembly, they are rarely tested. In subalpine grasslands, traditional management through manuring and hay-making results in intermediate productivity that is associated with high functional diversity. This functional diversity results from the ...

Tomato is the main vegetable crop cultivated in both open field and greenhouse in the world. One of the main problems for efficient irrigation management is the lack of information about irrigation requirements for the conditions of the Valley of Mexico; consequently, irrigation scheduling is empirical. In this paper daily irrigation requirements for tomatoes were obtained for a season, under the local conditions, with agronomic and climatic management, and typical infrastructure and plant density used in Chapingo, Mexico. Saladette type tomato (Lycopersicon esculentum Mill. cv. Tequila) was cultivated with a density of 4.3 plants m-2 in a polyethylene-covered greenhouse using tezontle as substrate and drip irrigated. The results show that the crop evapotranspiration changed from 0.2 L plant-1 in the initial stage to 1.5 L plant-1 in the maximum demand stage. The gross volume applied to each plant in the whole season was 143 L, water productivity was 35 kg m-3 and yield was 20 kg m-...

The objective of this study was to evaluate grain yield and yield components of popcorn with different nitrogen rates and plant densities. Field studies were conducted in 1995 and 1996 at Kazova Plain in Tokat. The experiment was designed in a randomized-complete-block design with a split-plot arrangement with three replications. The treatments comprised six levels of nitrogen (0, 50, 100,

Plant density and harvest methods for potato seed tuber multiplication in pots The limited volume of substrate might reduce tuber multiplication rates when production is carried out in pots. The results of potato seed tubers multiplication in pots are presented in this publication, taking into account different plant densities and harvest methods. Experiments were carried out in an aphid-proof screenhouse,
