Impact of Foliar Spray of NPK and Zn on Soybean for Growth, Yield, Quality, Energetics and Carbon Footprint under Dryland Condition at Indore

Background: Dryland is characterised by drought/dry spell (s) of 10 to 15 days and is the main reason for decline in soybean production. The aim of this study was to develop a strategy of drought amelioration by using foliar sprays and enhancement of yield, quality, energetics and carbon footprint. Methods: A field experiment was carried out at Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, College of Agriculture, Indore, (M.P.) during 2017-18 under spilt-plot design having two main plot treatments viz., foliar application at dry spell (F1), foliar application after dry spell (F2) and seven sub plot treatments i.e. different variants of foliar sprays (DVFS). Different growth, yield, quality, energetic and carbon footprint traits were recorded. The data were analyzed using standard statistical procedures. Result: The highest growth, yield, quality and energetic parameters were recorded for F1 as compared to F2. In case of DVFS, foliar application of water soluble complex fertilizer 19:19:19 (NPK) @ 0.5% + 0.5% ZnSO4 (T4) produced maximum values for growth, energetics, carbon footprint, oil (22.5%) and protein (43.1%) content as well as produced maximum yield.

The role of row crop predecessors in controlling weediness and increasing the productivity of rapeseed and rapeseed seeds

Practice shows that the demand for oilseeds is currently very high. Having the potential of large processing capacities in the southern part of the Non-Black Earth Zone of Russia, oilseeds are in high demand, characterizing rapeseed and rape as high-margin crops in agricultural production. The study of the influence of row crop predecessors on the productivity of cruciferous oilseeds in the conditions of this region is interesting and relevant, which served to determine the direction of research. The article presents data on determining the effectiveness of predecessors on weediness, growth and development, productivity of agrocenoses of rapeseed and rape of spring forms. On the dark gray forest soils of the Ryazan region, the maximum yield of oilseeds of rape and rape was obtained on the variants where the predecessor potato was chosen (2.80 t / ha for rape, 2.68 t / ha for rape), the minimum yield of rape and rape was obtained from the predecessor of corn for grain (2.55; 2.44 t / ha, respectively). A direct dependence of the weediness of crops to the yield of oilseeds of the studied crops was revealed. Keywords: RAPESEED, MUGGY, PREDECESSORS, CLOGGING, YIELD, QUALITY

Sustainable Development in the Agrifood Rice Chain in Timor-Leste

In Timor-Leste, rice is a source of livehood and a staple food. However, it presents persistently low yield, quality, price, and value to consumers, which, allied with climate projections and pressure for higher quality and productivity, raised logistics costs, and subsidized imports, creates a need to identify drivers/inhibitors of sustainable development. This chapter investigates rice agri-food chain sustainable development by recording the main actors involved and understanding their perspectives. Interviews, questionnaires, observation, and focus group have been applied to understand how sustainable development can be triggered. Results show that actors are not accurately coordinated to find a future sustainable development. An alignment of activities, innovation, best practices, and cooperation are recommended towards a future sustainability plan as a starting point to agrifood rice development. Each element of this development should be measured and quantified in future research.

Chromatographic Techniques for the Analysis of Organophosphate Pesticides with their Extraction Approach: A Review (2015-2020)

In agriculture, a wide range of OPPs have been employed to boost crop yield, quality, and storage life. However, due to the ever-increasing population and rapid urbanization, pesticide use has...

Effects of Foliar Applications of Some Macro and Micro Nutrients on Yield, Quality Attributes of Guava (Psidium Guajava L.)

Effects of foliar applied macro (NPK) and micro nutrients (Fe, Mn, Zn, Cu and B) at different time on yield, quality and benefit: cost ratio of rainy and winter season guava were evaluated in north western Haryana, India. The two season’s data depicted that physico- chemical characters with respect to fruit set, fruit retention, fruit size, average fruit weight and yield were significantly increased with foliar application of macro and micro nutrients at vegetative, flowering and fruiting stage (T7). The shoot C: N ratio was also found highest with T7 foliar treatment which was followed by T5 in both the seasons. The T7 foliar spray resulted in maximum benefit: cost ratio in both the seasons. Proper fertilization strategies can help fruit growers to get good yield and quality fruits. Bangladesh J. Bot. 50(4): 1159-1164, 2021 (December)

Efect of sowing dates and seed rates of flax intercropped with sugar beet on productivity of both crops and competitive relationships

The aim of intercropping flax on sugar beet is to increase the cultivated area with flax due to widely cultivated area of sugar beet. So, a field experiment was carried out to study the effect of various sowing dates and seed rates of flax intercropped with sugar beet on yield, quality and economic evaluation. The main-plots were assigned to three sowing dates of flax intercropped with sugar beet and the sub-plots were allocated to four seed rates of flax. The results show that sowing date of flax after 35 days from sowing (DFS) sugar beet resulted in the highest values of sugar beet yields and quality. Maximum values of flax straw and seed yields resulted from sowing flax after 21 DFS sugar beet. Intercropping sugar beet with flax at 12.5% from recommended seed rate on top sugar beet terraces attained the most elevated values of sugar beet yield and quality. Sowing flax at 50% from recommended rate resulted in the best values of flax technical and fruiting zone length, also straw and seed yield/hectare. The maximum yield and economic return of both crops were obtained from sowing flax at 12.5% from recommended rate after (21 or 35) DFS sugar beet.
