There is interest in the identification of the best seeding density for new corn hybrids and on reduced use of herbicides for weed control. The objective of this study was to evaluate the effects of seeding density (30, 50, 70, and 90 thousand plants ha) and weed control on green ear yield and grain yield in corn cultivar AG 1051. A completely randomized block design was adopted with split-plot...

India is a leader in the usage of ancient ayurveda system and blessed with vast richness medicinal herbs. Over 68 Ayurveda formulations contain medicine Guduchi as one its main constituents, need for this medication has climbed from 3000 to 6000 MT 9.1% yearly increase. Unfortunately, uncontrolled harvesting causing natural populations decline. There plenty room expand commercial production the...

The addition of organic compounds to fertilizers has shown positive effects on plant metabolism. This study aimed evaluate the macronutrient accumulation and productivity potato with use biofertilizer (BF) applied leaves. A 2×7 factorial plot a subdivided in time ten replications used two forms fertilization: chemical fertilizer conventional NPK (nitrogen, phosphorus potassium: control) plus bi...

Utilization of Solanum lycopersicum L. and its varieties contribute to plant biotechnology study the effect genes flower transition events. This aims optimize media light intensity for in vitro flowering a cherry tomato variety. Induction was carried out using seven types combined with 3 intensities, followed by feeding adding liquid medium MS+PBZ 1 mg/L. A positive response is shown at 2,600 l...

in order to study of hydropriming, planting depth and nitrogen split application effect on yield and yield components of double cross hybrid of corn, an experiment was carried out as factorial based on randomized complete block design (rcbd) with four replications. nitrogen split application included (400 kg/ha at sowing date, 100 kg/ha at sowing date and 300 kg/ha 25 to 50 days after sowing da...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

Reciprocal pollination was made between Lilium nobilissimum and L. regale. Pollen tubes reached the base of style within 144 h after pollination, but no mature seeds were obtained in either cross combination. Explants, or ovules-with-placental-tissue excised from each carpel 30 and 40 days after pollination (DAP), were cultured on a medium composed of major salts of B-5 macronutrient (Gamborg, ...

Late blight of potato caused by an oomycete, Phytophthora infestans (Mont.) De Bary limits the production worldwide. management has been based on chemical fungicide application, and repeated use these fungicides introduces new more aggressive genotypes, which can rapidly overcome host resistance. Therefore, innovative effective control measures are needed if is to be reduced or eliminated. Some...
