Different Soils

In two «dehesa» grasslands with different soils, one over slate and the other over granite, studies were carried out toinvestigate the influence that phosphoric fertilization, surface tillage of pastures and oat sowing have on the primaryproduction and its nutritive value, on the index of utilization of raining water, and on the evolution of oat stubble withtime. Additionally, economic studies of the previous results have been carried out. Phosphoric fertilization and superficialtilling of pastures did not have a relevant influence on the primary production. Additionally, in the successive regrowthover oat stubble there was no response to phosphoric fertilization. The production increments with respect tocontrols are related to the preparatory tillage for sowing the oats, and the changes that the vegetation experimented.This effect decreased with time. The dry matter production in the oat treatments was higher than in the pastures, bothin slate and granite soils. In dehesa systems the use of raining water for the production of 1 kg dry matter ha-1 was verylow, and, on the average, 0.278 and 0.588 l m-2 were needed in pastures, but this amount decreased significantly in theoats: 0.059 and 0.110 l m-2 in slates and granites, respectively; with better use of the water in the more fertile soils. Theeconomic response to the oat sowing was about 252 and of 160 euros ha-1 year-1 in slates and granites, but there was noeconomic response to the fertilization and superficial tilling of pastures during the period of the experiment.

Different Levels

A field experiment was carried out at Agricultural College Farm, Mahanandi in Kurnool district of Andhra Pradesh to study the effect of different levels of potassium and green manure on yield, dry matter production, content, uptake of potassium, available K and potassium use efficiency of rice during kharif 2015. The results revealed that the yield, dry matter production, content, uptake of potassium, available K and potassium use efficiency were significantly increased with increase in K fertilizer application and also due to green manure incorporation. The highest yield, dry matter production, content and uptake of potassium, available K were obtained with incorporation of green manure (Dhaincha @ 5 t ha-1) +120 kg K2 O ha-1 which was on par with (Dhaincha @ 5 t ha-1) +80 kg K2 O ha-1and (Dhaincha @ 5 t ha-1)+40 kg K2 O ha-1. Among all the treatments the highest KUE was observed with T6 ((Dhaincha @ 5 t ha-1) +40 kg K2 O ha-1) followed by T7 ((Dhaincha @ 5 t ha-1) + 80 kg K2 O ha-1) and T8 ((Dhaincha @ 5 t ha-1) +120 kg K2 O ha-1). Among the levels of K fertilizer, the highest potassium use efficiency was recorded at 100% RDK (80 kg K2 O ha-1) followed by 150% RDK (120 kg K2 O ha-1)
