A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

In this study, the effects of different pruning heights and number of branches left were evaluated to determine the most effective pruning height and optimum number of branches to be left after branch thinning to increase seed yield production of Jatropha curcas. The experiment, which was conducted at the MMSU Experimental Station from 2009-2011, was laid-out in Split plot design and was replic...

The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

in order to investigate the effect of organic and chemical fertilizers on growth characteristics of marjoram, a factorial experiment was conducted based on randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad during 2012-2013 growing season. treatments were comprised of four urea levels (0, 21.7, 108.7 and 195.7 kg.ha-1) a...

sustainable development of the production in every region requires consideration of energy flow in the production system, moreover, investigating the production system inputs from environmental management point of view is of high importance. in this study energy use and greenhouse gas emissions is investigated. data were collected through interviews with 75 tea farmers and comparing the results...

This study was carried out to determine the effects of putrescine(Put) and humic acid (HA) foliar applications on growth, yield and chemical composition of Egyptian cotton (Gossypium barbadense L. cv. Giza 90)plants grown under saline soil condition. A soil mixture of, clay: sand (1:1), was used as a plant growing media. Three different doses of putrescine (0, 1 and 2 ppm) and humic acid (0, 1 ...

ABSTRACT- One of the big problems today human societies are faced with is the problem of soil erosion. In this study, the "MPSIAC model" was used to estimate sediment yield and provide sediment yield map in Cachoyeh watershed. The MPSIAC method incorporates nine environmental factors that contribute to sediment yield of the watershed. These factors are: surface geology, soil, climate, runoff, t...

Six cowpea genotypes (Danila, IT96D-772, IT90K-277-2, IT95K-1091-3, IT96D-740, IT96D-757) were intercropped with a local millet cultivar using four row arrangements (1:1, 1:2, 2:2 and 2:4 millet to cowpea rows) in a field experiment conducted at Minjibir near Kano in the Sudan savanna ecological zone of Nigeria during the 1999 and 2000 wet seasons. Cowpea genotypes and row arrangement had no ef...
