Field experiment was conducted for 2 seasons to study the influence of drip fertigation in combination with or without bio fertilizers on yield, plant uptake and soil fertility of Bt cotton. The treatments comprised of four levels of drip fertigation viz., 75, 100, 125 and 150 per cent of recommended dose of fertilizers (RDF, NPK) combined with and without bio fertilizers, drip irrigation w...

Grass pea (Lathyrus sativus L.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of Iran. It is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. To study the seed and DryMatter (DM) yield and agronomic traits, six genotypes of Lathyrus sativus L. and twogenotypes of Lathyrus inconspicuous L. were provided b...

Pepper is one of the nutrition demanding vegetable. In order to compare N fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. In which fertilizer was the main factor and included Ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. Half of these amounts appliedpre planting ...

A complete diallel cross using eight flax genotypes including four Iranian breeding lines and four Canadian genotypes was carried out to estimate genetic parameters for days to flowering, days to maturity, plant height, primary branches per plant, number of capsules per plant, number of seeds per capsule, seed yield per plant, 1000-seed weight, seed yield and harvest index. Analysis of variance...

five genotypes of chickpea as a half diallel crossed with each other, in 2008, 5 parents and 10 progenies were planted as randomized complete block design and some traits including days to podding, basal pod height, number of pods per plant, number of double seed pods per plant, number of single seed pods per plant, number of empty pods per plant, seeds per plant and seed yield per plant were e...

safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...

in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...
