Scarcity of water during tree establishment can be overcome by making circular catchment around the tree seedling. Integration of treatments viz. catchment area and farm yard manure was done to test the increase in profile moisture and ultimately increase in survival and growth of Prosopis cineraria , an important multipurpose tree of desert ecosystems. The results of the field experiment showed that after 36 months of planting there was a four fold increase in plant height with catchment area of 12.6 m2 as compared to control. Farm Yard Manure (FYM) was not found effective statistically. Also no interaction effect was observed in the different combination of the levels of both the two factors i.e. catchment size and FYM application.- forage Yields of Cenchrus ciliaris and Lasiurus sindicus Grown in Association with Trees under Arid Conditions

Field trials conducted at Central Arid Zone Research Institute, Jodhpur, for seven consecutive years (1988 to 1994) revealed that yields of Cenchrus ciliaris and Lasiurus sindicus grown in association with trees were lower than the yields of sole grasses. The changes in height of Acacia tortilis and Zizyphus rotundifolia were also more under the control. The height of trees decreased in association with grasses. The average soil moisture stored in the 90 cm profile under A. tortilis was lower as compared to Z. rotundifolia. Moisture storage decreased further when the grasses were grown with the trees. Organic matter increased over the initial level in all tree-grass combinations. The uptake of P by the two grasses alone or in combination with trees, was marginally different. While the uptake of Ca, Mg and K was considerably higher by L. sindicus than C. ciliaris.- Compatibility Studies on Acacia tortilis and Zizyphus rotundifolia with Field Crops under Arid Conditions

The effect of growing pearlmillet and clusterbean crops in association with Acacia tortilis and Zizyphus rotundifolia on tree growth, crop yields, soil moisture and organic matter were ascertained for four consecutive years under arid conditions. The results revealed that the grain and straw yields of pearlmillet and clusterbean grown in association with trees decreased compared to sole crops. The reductions in yields under Acacia tortilis were more than Zizyphus rotundifolia. Clusterbean suffered greater reduction as compared to pearlmillet. Growth of trees was maximum in the control (Tree alone) while in association with the crops it decreased. Height increment in A. tortilis was more in association with clusterbean than that with pearlmillet while Z. rotundifolia attained greater height when in association with pearlmillet. Profile moisture stored at the time of crop harvest was maximum in sole crop of clusterbean and higher in clusterbean.Z. rotundifolia than clusterbean.A. tortilis. The organic matter content of soil after four years increased over the initial and followed the order: Clusterbean > Pearlmillet and Z. rotundifolia > A. tortilis.- Effect of Integrated Moisture Conservation Technology on the Early Growth and Establishment of Acacia tortilis in the Indian Desert

A study was conducted during the years 1982 and 1983 to find out the effect of integration of moisture conservation technology like sub-surface moisture barrier, water harvesting, soil amendments and the mulching on the early growth and establishment of Acacia tortilis seedlings. The results showed that the placement of pond sediments at the bottom of 60 cm deep pit in 5 mm thickness in association with water harvesting from circular catchment (2% slope and 1.5 m radius) and the soil mixed with pond sediment, (10 kg/pit) and the farm-yard manure (5 kg/pit) as amendments markedly increased the moisture storage capacity of the pit,optimized the thermal conditions of soil and thus increased the growth of Acacia tortilis plants as reflected by the increase in plant height, canopy diameter, collar diameter and breast height diameter. The technique can be successfully used in checking the mortality, boosting the early growth and the establishment of trees in the desert and similar areas.- A Note on the Efficiency of Rubble Mulch in Conserving Soil Moisture

Soil physico-chemical and ecological studies in twelve years old five desert tree plantations were undertaken at Jodhpur. The results showed that density, number and height of ground flora species and above ground phytomass production was higher under Prosopis cineraria and Tecomella undulata and lowest under P. juliflora. The growth of former two species has also increased the soil fertility status with respect to organic carbon, total N and P205 and available macro and micro-nutrients. Data of moisture distribution showed higher moisture content in surface soil under P. cineraria and in 75-90 cm depth under Tecomella undulata.- A Note on some Soil Moisture Changes under Permanent Vegetative Cover
