A field experiment was conducted for two consecutive seasons to assess the impact of four plant spacing (10, 20, 30 and 40 cm) and three weeding levels (no weeding, weeding once (at two weeks from sowing) and weeding twice (at two weeks and at four weeks) on growth and yield of peanut (groundnut). An overview of research into peanut breeding, varieties, improvement and evaluation crop duration current research is evaluating various row and plant spacing configurations to make up for the yield loss back to top numerous papers outlining this work have been published in the scientific literature. Abstract: plant analysis has been used as a method for determining the relative quantities of mineral elements in plants in order to measure the leaf n, p, k and mg of groundnuts (arachis hypogaea l) grown under irrigation, an experiment was done on at a fixed inter-row spacing of 50cm the intra.
The responses in the growth of peanuts (arachis hypogaea l cv florunner) to plant density and to spatial ratio (ratio of inter-row: intra-row spacing) in a tropical monsoonal environment were investigated biological yield (above-ground biomass plus pods) was unresponsive to spatial ratio over the range 1:1-1:7:19, but it.
Loose soil, use of blade harrow within the inter row spacing of groundnut is a widely followed method for effective weed control as it cuts the root system and weed die owing to desiccation harrowing also loosen the soil considerably and thus, has a good impact on peg penetration and pod development it also act as a soil. An experiment was conducted at the crop botany field laboratory of bangladesh agricultural university, mymensingh, during the period extended from november 2010 to april 2011 to study the effect of row spacing on the growth and yield of peanut (arachis hypogaea) the experiment comprised five row spacings viz. Studies in peanut row spacing dating back as far as the late 1800s, many years prior to mechanization of the peanut harvest, have generally commented that narrow spacing results in higher yields and reduced weed pressure row spacing was recommended primarily on optimal yield, with superseding.

Determination of coefficient defining leaf area development in different genotypes , plant types and planting densities in peanut (arachis hypogeae l) each plot (2 m2) contained two rows (2-m long, 50-cm distance between rows), with a spacing of 10 cm between plants within a row, giving a total of 40 plants per plot.
