Since the recent legalization of medical and recreational use cannabis ( Cannabis sativa ) in many regions worldwide, there has been high demand for research to improve yield quality. With paucity scientific literature on topic, this study investigated relationships between light intensity (LI) photosynthesis, inflorescence yield, quality grown an indoor environment. After growing vegetatively ...

Traditional Chinese medicine relies heavily on herbs, yet there is no information on how these herb plants would respond to climate change. In order to gain insight into such response, we studied the effect of elevated [CO2] on Isatis indigotica Fort, one of the most popular Chinese herb plants. The changes in leaf photosynthesis, chlorophyll fluorescence, leaf ultrastructure and biomass yield ...

The studies on growth regulation in black gram cv. ADT (Aduthurai) 5 exhibited significant changes in growth, physiology and yield due to chemicals and plant growth regulators. Foliar application of NAA @ 40ppm at pre-flowering stage influenced growth characteristics by showing increased plant height, more number of branches, higher leaf area index and leaf area duration. But, with regard to ph...

this study assessed the optimum water need of pepper (capsicum annuum l. cv. california wonder) and the critical irrigation level to be applied in order to achieve a reasonable economic yield in water shortage conditions. in a controlled field experiment involving five different treatments, seasonal evapotranspiration for pepper fluctuated from 89 mm in the severe stress treatment (i0.00) to 1,...

agroecology emphasizes the use of organic materials in agriculture. the organic acids are important sources of organic materials. in order to study the effect of different levels of humic acid on yield and yield components of corn (zea mays l.) an experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, during 2009. the experiment was conducted...

Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...

A field experiment was conducted to study the effects of N fertilization on uptake,accumulation/remobilization, use efficiency and yield of sunflower grown in alluvial plains ofnorthwestern India comprising four hybrids (PSH 996, PAC 3789, PSH 569 and SH 3322)and five N levels (Control, 40, 80, 100 and 120 kg N ha-1) in split-plot design with threereplications. Increased N fertilizer rates sign...

Field research was conducted at Students Farm, Sindh Agriculture University, Tandojam, Pakistan, during 2005 and 2006. The sunflower variety HO-1 was treated with 0-0, 101.5, 10-2, 15 -1.5, 15-2.0, 201.5 and 202.0 Zn-B kg ha. A basal dose of N, P, and K was applied at the rates of 90, 45 and 45 kg ha respectively across Zn-B treatments. The increase in Zn and B fertility from 10-1.5 to 20-2 kg ...
