Soybean (glycine max. (l.) Merrill) vegetative growth performance under chemical and organic manures nutrient management system
Optimization of fertilizers sources and doses occupies pivotal position for triggering crops growth along with reducing a halt to environmental pollution caused by excessive use of mineral fertilizers. This field research was conducted to determine the effect of chemical and organic fertilizers on vital vegetative growth parameters including leaf area index and chlorophyll content of soybean (cv. Nova).Treatments included four different sources of fertilizers manures from sheep and cattle barns, liquid manure from cattle barn, chemical fertilizers and a control treatment was kept for comparison purpose. The chlorophyll contents of plants at different growing stages Beginning bloom (R1) and Beginning seed (R5) were measured using SPAD-502 and CM 1000 chlorophyll meter. The results indicated that physiological growth parameters including leaf area index and chlorophyll content of soybean differed significantly at stage R1 and R5 growth stages under varying fertilization regimes. The chemical fertilizers remained unmatched for recording the maximum physiological growth, while liquid manure from cattle barn performed superiorly by exhibiting the maximum leaf area index and chlorophyll content. It is recommended to use liquid manure from cattle barn for boosting physiological growth of soybean and these research findings also necessitate evaluation of different doses of liquid cattle manure to sort out the best performing dose for soybean production under changing climate
Evaluation of turmeric-mung bean intercrop productivity through competition functions
An intercropping experiment was conducted with varying combinations of turmeric and mung bean to find out the efficacy of productivity and economic return through competition functions. Treatments were evaluated on the basis of several competition functions, such as land equivalent ratio (LER), aggressiveness, competitive ratio (CR), monetary advantage index (MAI) and system productivity index (SPI). Results showed that rhizome yields of turmeric were higher in intercropping system than in mono crop. It indicated that intercropping of mung bean did not affect the rhizome yield of turmeric. However, turmeric (100 %) + 3 row mung bean (100 %) in between turmeric lines intercropping system exhibited maximum yield of both the crops as well as turmeric equivalent yield, LER, competitive indices values, SPI and MAI (Tk. 2,44,734.46 ha-1) compared to the other intercropping combinations and the mono crops. Aggressiveness of intercrop indicated dominance of turmeric over mung bean in all the combinations except turmeric (100 %) + 1 row mung bean (33 %). Competition functions of intercroping suggested beneficial association of turmeric and mung bean crops. The study revealed that mung bean could be introduced as intercrop with turmeric without hampering rhizome yield with higher benefit additionally increasing mung bean production area. © 2018 University of Ljubljana.

Fertilisation source and dose optimisation boost yield of durum wheat in Mediterranean climatic conditions
Climate change, global
warming, environmental pollution,
greenhouse gas emissions from
agricultural fields, stagnant wheat yields
and reduced farm economic returns require
optimisation of sources and doses of plant
nutrients. A field study was conducted to
evaluate wheat response to different forms
of fertilisers and nitrogen (N) doses under
Mediterranean conditions. The field trial
was comprised of fertiliser sources,
including chemical fertilisers, compost and
leonardite, while different nitrogen levels
(0, 80, 160, 240 kg ha-1) were also tested.
The experimental variables included yield
attributes (height of the, length of the
spike, spikelets number per spike,
thousand-grain weight and grain yield). In
addition, nutritional quality attributes like
protein and starch contents were studied
along with NDVI values of wheat under
different fertilisation regimes. The trial
was executed using a randomised
complete block (factorial) design using
four replications. The results revealed that
fertiliser forms and N doses remained
ineffective for boosting yield attributes of
wheat. For nutritional characteristics of
wheat grains, a higher N dose remained
instrumental in boosting protein, starch
and wet gluten contents. Thus, 240 kg ha-1
of N dose might be recommended for
general adoption under Mediterranean
conditions; however, study findings are
limited in scope and further in-depth
studies are needed by testing organic
manures from plant and animal origins
