An experiment was conducted to determine effects of inter-cropping lablab (Lablab purpureus) with 3 selected early-maturing sorghum (Sorghum bicolor) varieties (Teshale, Girana-1 and Misikir) on plant morphology, sorghum grain and forage yield and quality plus yield and quality of lablab forage, and to assess farmers’ perceptions of the crops in Kalu District, South Wollo, Ethiopia. Seven treatments, namely: T1 - sole lablab (SL); T2 - Teshale + lablab (TL); T3 - Girana-1 + lablab (GL); T4 - Misikir + lablab (ML); T5 - sole Teshale (ST); T6 - sole Girana-1 (SG); and T7 - sole Misikir (SM), were used with 3 replications in a randomized complete block design. The data collected from sorghum varieties were: plant height, number of leaves per plant, leaf area, dry biomass yield and grain yield; and for lablab was: plant height, number of leaves per plant, leaf area, number of branches per plant, number of nodules per plant and dry biomass yield. Grain yield was determined on sorghum at maturity, while lablab was harvested at 50% flowering. Inter-cropped Girana-1 produced yields of both grain and stover and lablab forage similar to those for pure stands of the 2 crops, while inter-cropping of Teshale and Misikir with lablab reduced height, grain and stover yields of sorghum and yields of lablab forage (P<0.05). However, crude protein concentration in sorghum stover was enhanced when grown as an inter-crop with lablab (P<0.05). Land equivalent ratios for inter-crop treatments were 54‒87% higher than those for pure stands. Farmers readily identified the combination Girana-1 + lablab as superior to the other associations. While farmers can improve productivity of their farms by inter-cropping these sorghum varieties, preferably Girana-1, with lablab, more studies should be conducted to determine benefits from sowing other legumes with sorghum. Any improvements in soil N levels from planting the legumes should be quantified.

Aims: This field experiment was conducted to compare the combined application of different rates of potassium and zinc application against the standard farmers practised application rate based on dry matter distribution, net photosynthesis, transpiration rate, sub stomatal C02 concentration, stomatal conductance, grain yield and quality attributes (protein and carbohydrate content and yield).  Place and Duration of Study: This short-term field trial was conducted on the Agronomy Research Farm of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India on the Kharif (Post monsoon) season of 2016. Methodology: The experiment was conducted in Factorial Randomized Block Design (FRBD) with two factors i.e., potassium and zinc, each having three levels. The experiment was replicated thrice. The three potassium levels were 30, 60 and 90 kg K2O ha-1 while the zinc was applied 20, 30 and 40 kg ZnSO4.7H2O ha-1 as three distinctive levels.  A short duration dwarf maize cultivar Ravi-81 was used for the experiment. Results: Perusal of experiment results confirmed that potassium and zinc have positive interaction even in short duration crop under dryland condition. The higher dry matter accumulation, crop growth rate, photosynthetic attributes, yield, protein content, protein yield, and carbohydrate yield has been recorded with the application of potassium at a rate of 60 kg K2O ha-1 along with zinc application of 30 kg ZnSO4.7H2O ha-1 which has been found to be statistically superior over farmers adopted practice (30 kg K2O ha-1 along with zinc application of 20 kg ZnSO4.7H2O ha-1). Conclusion: Combined application of potassium and zinc has positive interaction on each other, and the increased rate is needed to meet the demand for short duration high yielding maize crop for enhanced growth, yield and quality attributes.
