Optimization of phosphorus levels for enhancing groundnut productivity under different land configuration in semi-arid ecologies of Afghanistan

A field experiment was conducted at the research farm of Kunduz Spinzar State-Owned Corporation in Collaboration with Kunduz University to evaluate response of cotton varieties to phosphorus fertilizer on growth, yield and economic efficiency in northeast of Afghanistan, the experimental design was Randomized Complete Block Design (RCBD) With split arrangement each replicated thrice, The study involved three cotton varieties (CD-401, AND-123 and K-01) and four phosphorus fertilizer levels (control, 30 kg p2o5/ha, 60 kg p2o5/ha and 90 kg p2o5/ha), different cotton varieties and phosphorus have significant impact on yield and economic parameters, the maximum Lint Cotton yield (1,749.02 kg/ha), Seed Cotton yield (3,666.07 kg/ha), Lint Cotton Yield (187,390AFN/ha), Seed Cotton yield (167,539 AFN/ha), gross return (354,929 AFN/ha), net return (339,876 AFN/ha) and B: Cost ratio (7.67) was in AND-123 variety compared with CD-401 and K-01 varieties respectively. The highest Lint Cotton yield (1,627.50 kg/ha), Seed Cotton yield (3,110.38 kg/ha), Lint Cotton Yield (174,370AFN/ha), Seed Cotton yield (142,144 AFN/ha), gross return (316,515 AFN/ha), net return (297,790 AFN/ha) and B: Cost ratio (7.67) was in 90 kg P2O5 kg ha-1 followed by phosphorus application of 60 kg P2O5 kg ha-1, 30 kg P2O5 kg ha-1 and control respectively. It can be concluded AND-123 cotton variety along with 90 kg p2o5/ha is the best combination for cotton productivity and profitability in northeast of Afghanistan.

An experiment was conducted at the farm of Afghanistan National Agricultural Science and Technology University (ANASTU), Kandahar Province, Afghanistan in cropping season of 2020 to investigate the Optimization of Crop Establishment methods and Phosphorus Fertilizer levels on Growth and Economic Efficiency of Groundnut under Semi-arid region of Afghanistan. The experimentation was conducted in split-plot design with 15 treatment combinations and replicated thrice. main-plot consisted of crop establishment methods, viz. ridge and furrow (RF), broad bed and furrow (BBF) and flatbed (FB), while the sub-plots comprised of phosphorus levels, viz. absolute control, 20, 40, 60 and 80 kg P2O5/ ha. The results of the investigation revealed that the growth parameters in terms of plant height in and leave area were highest in BBF, followed by FB and minimum was in RF. Adoption of BBF recorded significantly higher gross return (238928 AFN/ha), net return (202728 AFN/ha) and net benefit cost of ratio (5.2) were in Broad Bed and Furrow, followed in ridged and furrow and the minimum was in flat bed method. It can be concluded, cultivating of groundnut with Broad Bed and Furrow with application of 60 kg P2O5/ha was found beneficial for reaching higher productivity and profitability under semi-arid region of Afghanistan.

A field experiment Conducted at the farm of Kunduz University during cropping season of 2023 to evaluate Effects of Nitrogen Application on Growth and Yield of Groundnut (Arachis hypogaea L.) in northeast of Afghanistan. The field experiment laid out in Randomized Complete Block Design with three replications, the treatments were Nitrogen fertilizer levels viz. Control, 15 kg N/ha, 30 kg N/ha and 45 kg N/ha respectively, result of the study revealed the highest Plant Height (32.61cm), Branches/plant (10.05), Leave area index (5.20), Kernel/pod (2.23), Pod weight (24.46), Pods/plant (32.30), 100- seed weight (76.38gr), Pod yield (2.89t/ha), haulm yield (5.53t/ha) and Biological yield (8.42t/ha) were in treatment with application 45 kg N/ha, the minimum growth and yield parameters were in Control plots, it can be concluded nitrogen fertilizer at the rate of 45 kg N/ha is optimum level for enhancing groundnut productivity and profitability in northeast of Afghanistan.
