Peanut (Arachis hypogea L.) is an important nut crop extensively grown in rainfed regions of Pakistan. The crop requires low inputs; thus, could grow successfully under diverse environmental conditions. Due to pegging ability, peanut grows aggressively in sandy and sandy-loam soils. However, it has not introduced to Thal region of southern Punjab, Pakistan. A two-year field experiment was conducted to optimize sowing dates for two peanut genotypes (‘BARI-2016’ and ‘NO-334’) in Thal region (Layyah). Similarly, a yield trial was conducted at Chakwal where both genotypes are extensively grown. Five sowing dates (10th April, 1st May, 20th May, 10th June and 30th June) were included in the study. The highest seed yield was obtained with early sown crop (10th April) during both years. Pod formation reduced with increasing atmospheric temperature and no pods were formed on the plants sown on 30th June. Decreased pod formation seemed a major reason for low yield in late-sown crop. The highest yield was observed for the crop sown on 10th April, which was decreased by 40% for the crop sown on 1st May. Genotype ‘BARI-2016’ performed better for seed yield at both locations compared with ‘NO-334’. The results suggested that genotype ‘BARI-2016’ is more adaptive to arid and semi-arid condition under rainfed or irrigated conditions. Sowing peanut at optimum time would increase seed yield in arid and semi-arid regions. Nonetheless, ‘BARI-2016’ can be grown under rainfed and irrigated conditions successfully.

Camelina sativa is a promising oilseed crop used for dietary oil and as a biofuel feedstock. C. sativa is a highly adaptable, cool season crop that can be grown on marginal lands with minimal inputs, making it potentially suitable for growth in Northern Nevada and other cooler and drier semi-arid regions of North America. A five-year (2011 to 2015) field trial was conducted to evaluate the seed yield, oil content, and oil and biodiesel production potential of eight C. sativa cultivars in semi-arid regions of Northern Nevada. Columbia, Cheyenne, Calena, and Blaine Creek were ranked as the top four varieties based on the five-year study of mean seed yield, oil content, and estimated oil and biodiesel production values, although none of the cultivars were significant (p > 0.05). Overall, Columbia displayed the highest seed yield, harvest index, oil yield and potential biodiesel production of 910 kg ha−1, 0.147, 273.4 kg ha−1, and 86.4 L ha−1, respectively, across five growing seasons. For each individual year across the eight cultivars, seed yield, oil content, oil and potential biodiesel production was highest in 2015, and lowest in 2012 and 2013 (the drier years). The seed yields of this study fall within the ranges of yields reported in both the irrigated and rainfed locations of the Western United States. Based on the seed yield, oil, and the estimated oil and biodiesel productivity reported in this study, C. sativa can be grown successfully with supplemental irrigation in semi-arid environments like Nevada.

SUMMARYA breeding programme was initiated to develop populations of sunflower (Helianthus annuus L.), suitable for the semi-arid regions of Iran. Crosses were made between Chernianka 66 (having low yield, low oil content, short stem, and early maturity), as the female parent and VNIMK 8931 and Record (having high yield, high oil content, long stem, and late maturity) as the male parents. Selection, together with selfing and sib-crossing, resulted in six populations with high yields, high oil content, short stems, and early maturity.Correlation coefficients of oil yield and its components, i.e. seed yield and oil content, were highly significant and significant respectively. Capitulum diameter had highly significant correlations with seed yield and oil yield. Earlier maturity was associated with shorter stems and lower oil content.

Cumin is one of the important spice crops grown in arid and semi arid regions of India and is being adopted to cure some of the dreaded diseases. Determination of optimum water requirement which is function of soil crop and atmosphere is needed for achieving more profit and higher productivity per unit of water. Keeping in view, a field experiment was undertaken to access the conjugate impact of three irrigation regimes (0.6IW/ETc, 0.8IW/ETc and1.0IW/ETc) and three lateral spacing (0.60m, 0.70m and 0.80m) on productivity of cumin. Split plot design with three treatment replications was adopted. Drip irrigation with 0.8 IW/ETc resulted higher seed yield, plant height and dry matter of 1344.17 kg/ha, 36.42 cm and 2365 kg/ha respectively at 0.8 IW/ETc with lateral spacing 0.6 m as compared to other treatments. Highest water use efficiency (5.58 kg/ha.mm) was observed at 0.6 IW/ETc with 0.60 m lateral spacing. Highest B:C ratio (2.27) observed at 0.8 IW/ETcwith lateral spacing 0.6m as compared to other treatments.

Greenhouse experiments were conducted for two consecutive seasons to investigate the influence of volunteer durum wheat cultivars and density on lentil growth and yield. It is speculated that interference may be severe whenever wheat and lentils are rotated in semi-arid regions. Lentil:durum wheat ratios of 1:0, 1:1, 1:2, 1:4 and 1:6 were evaluated utilizing two durum wheat cultivars, Hourani and ACSAD 65. The results indicated that wheat interference did not influence lentil growth for the first 80 days after crop emergence, but afterwards, the lentil height, straw and seed yield were affected by the presence of wheat. A 50% reduction in either lentil straw or seed yield was estimated from the interference of a single plant per pot. The semi-tall cultivar Hourani had more adverse effects on lentil growth and yield than the semi-dwarf cultivar ACSAD 65.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.
