“…The different conservation measures improve cashew yield as reported by Badhe and Magar (2004) and in almond by Kumar (2016) under rainfed conditions. Various mulch materials are also known to conserve soil moisture during dry spell period for productivity improvement in mango (Ghosh andBauri 2003 andKumar et al 2008), in guava (Singh et al 2015), in turmeric (Kumar et al 2002), in apple (Lal et al 2003, Kumar et al 2013, Pandey et al 2005, in plum (Sharma and Kathiravan 2009) and in strawberry (Ali and Gaur 2007). Mulching has been found beneficial in improving physical and biological health of soil (Garg et al 2007) However, very limited work has been done on rain water harvesting and mulching in almond under rainfed conditions of the Kashmir valley.…”

A field experiment was conducted to study the effect of moisture conservation techniques on productivity enhancement in almond (Prunus dulcis Mill) during 2010-11 to 2012-13 at Srinagar, Jammu and Kashmir. Treatment sincluded five water harvesting techniques, viz. half-moon (W1), full-moon (W2), cup and plate (W3), trench (W4) and control (W5) and three mulch materials, viz. plastic mulch (M1), organic mulch (M2) and control (M3) were laid out in factorial randomized block design with three replication. The experimental results revealed that maximum mean trunk cross sectional area (266.82 cm2), nut yield (5.37 kg/tree), productivity efficiency (19.47 g/cm2 TCSA) and soil moisture content (13.48%) were recorded in full moon water harvesting technique. Among mulch material, plastic mulch found better in respect to TCSA (255.59 cm2), nut yield (4.99 kg/tree), productivity efficiency (18.88 g/cm2 TCSA) and soil moisture content (12.86%) compared to other treatments. The combined effect of water harvesting and mulching indicated that maximum TCSA (270.48 cm2), nut yield (5.82 kg/tree), productivity efficiency (20.92 g/cm2 TCSA) and soil moisture (13.98 %) were recorded in full moon water harvesting + plastic mulch in almond cultivar Non Pareil under rainfed conditions of north west Himalayan regions of India.

The design and selection of ideal emitter discharge rates can be aided by accurate information regarding the wetted soil pattern under surface drip irrigation. The current field investigation was conducted in an apple orchard in SKUAST- Kashmir, Jammu and Kashmir, a Union Territory of India, during 2017–2019. The objective of the experiment was to examine the movement of moisture over time and assess the extent of wetting in both horizontal and vertical directions under point source drip irrigation with discharge rates of 2, 4, and 8 L h−1. At 30, 60, and 120 min since the beginning of irrigation, a soil pit was dug across the length of the wetted area on the surface in order to measure the wetting pattern. For measuring the soil moisture movement and wetted soil width and depth, three replicas of soil samples were collected according to the treatment and the average value were considered. As a result, 54 different experiments were conducted, resulting in the digging of pits [3 emitter discharge rates × 3 application times × 3 replications × 2 (after application and 24 after application)]. This study utilized the Drip-Irriwater model to evaluate and validate the accuracy of predictions of wetting fronts and soil moisture dynamics in both orientations. Results showed that the modeled values were very close to the actual field values, with a mean absolute error of 0.018, a mean bias error of 0.0005, a mean absolute percentage error of 7.3, a root mean square error of 0.023, a Pearson coefficient of 0.951, a coefficient of correlation of 0.918, and a Nash–Sutcliffe model efficiency coefficient of 0.887. The wetted width just after irrigation was measured at 14.65, 16.65, and 20.62 cm; 16.20, 20.25, and 23.90 cm; and 20.00, 24.50, and 28.81 cm in 2, 4, and 8 L h−1, at 30, 60, and 120 min, respectively, while the wetted depth was observed 13.10, 16.20, and 20.44 cm; 15.10, 21.50, and 26.00 cm; 19.40, 25.00, and 31.00 cm, respectively. As the flow rate from the emitter increased, the amount of moisture dissemination grew (both immediately and 24 h after irrigation). The soil moisture contents were observed 0.4300, 0.3808, 0.2298, 0.1604, and 0.1600 cm3 cm−3 just after irrigation in 2 L h−1 while 0.4300, 0.3841, 0.2385, 0.1607, and 0.1600 cm3 cm−3 were in 4 L h−1 and 0.4300, 0.3852, 0.2417, 0.1608, and 0.1600 cm3 cm−3 were in 8 L h−1 at 5, 10, 15, 20, and 25 cm soil depth in 30 min of application time. Similar distinct increments were found in 60, and 120 min of irrigation. The findings suggest that this simple model, which only requires soil, irrigation, and simulation parameters, is a valuable and practical tool for irrigation design. It provides information on soil wetting patterns and soil moisture distribution under a single emitter, which is important for effectively planning and designing a drip irrigation system. Investigating soil wetting patterns and moisture redistribution in the soil profile under point source drip irrigation helps promote efficient planning and design of a drip irrigation system.

“…Hence, effective management of water resources is necessary if improved crop yields are to be obtained. The estimation of crop water requirements is essential for the precise scheduling of irrigation in field crops (Kumar et al, 2018; Kumar et al, 2020; Shankar et al, 2017). This requires information on the various surface and subsurface processes involved in moisture dynamics through the soil plant atmosphere continuum (SPAC).…”

The study evaluates an empirical equation to compute the nonlinearity parameter ‘β’ of a root water uptake (RWU) model for a variety of crops. A numerical model for simulating the soil moisture dynamics incorporating the RWU model was used to evaluate the efficacy of the empirical equation. Field experiments on seven crops, namely maize, pea, wheat, sorghum, Indian mustard, guar and potato, were conducted at Hamirpur, India. The soil moisture depletion and moisture status at different depths in the crop root zone predicted by the numerical model reflected satisfactory agreement with the experimentally observed values. The qualitative and quantitative comparative analysis establishes the efficacy of the empirical nonlinearity parameter‐based RWU model in predicting moisture uptake in the root zone for different varieties of crops. The nonlinearity of moisture extraction in the root zone varies for different crops as well as during different growth stages in the same crop.
