“…Here, rice farming is currently facing manifold constraints [2] that limit the possibility in getting adequate productive and economic results. managed as a dry crop until the tillering stage; after then, the ponding water depth is maintained until the final drying, except for drying periods needed to apply fertilizers; and (ii) dry seeding and intermittent irrigation, i.e., aerobic rice [27]. It is a particular form of the previous strategy, operated especially in areas close to urban settlements and in presence of water scarcity.…”

Due to the changing climatic and environmental conditions, modifications in agricultural and water policies have been made, and irrigated agriculture has to face the challenge of making a rational and optimal use of the water resource effectively available. This urges rice farming, strongly and traditionally linked to water, to change the modalities for the use of the resource. If on one hand water saving techniques should be preferred, a different water management in paddy fields may lead to lower yields and higher production costs, with consequent repercussions on farm incomes. The paper recognizes the disagreement between environmental and economic concerns and aims at contributing to the discussion about how to reconcile them by adopting alternative irrigation strategies. From this perspective, a multi-objective linear optimization model is used to explore the trade-offs between conflicting objectives in a rice-growing area in Northern Italy. The model returns the optimal allocation of land subject to three different irrigation strategies, as those previously performed in experimental fields; in addition, a scenario analysis is run to simulate reduced resource availability. Results demonstrate the key role of prioritizing one objective over the other, while introducing cultivars more suitable for dry cultivation enables enlarging the frontier of optimal solutions.

“…Growing rice under water saving systems such as alternate wetting and drying (AWD) and aerobic rice (AR) may decrease grain quality owing to quick moisture loss and resultant water stress (Dingkuhn and Gal, 1996;Zhang et al, 2008). However, growing rice under AWD and AR is inevitable in the wake of worldwide water shortages (Rejesus et al, 2011;Nie et al, 2012;Price et al, 2013;Ye et al, 2013). Nevertheless, the quick moisture loss from the rice fields sown by AR and AWD methods can be avoided applying mulches .…”

“…Energy and water are significantly saved under the water saving rice cultivation systems. Aerobic rice cultivation system (AR) and alternate wetting and drying (AWD) are the most important water saving rice cultivation methods which are under development throughout the world's important rice growing areas (Jabran et al, 2012b;Nie et al, 2012;Ye et al, 2013). Importantly, these rice cultivation systems lack a standing layer of water compared with the conventional method (Nie et al, 2012).…”

Although water inputs are lower for AR and AWD, however, higher evaporative moisture losses in these systems may adversely affect the rice crop growth and produce's quality (Zhang et al, 2008;Pandey et al, 2014).…”

To cite this paper: Jabran, K., E. Ullah and N. Akbar, 2015. Mulching improves crop growth, grain length, head rice and milling recovery of basmati rice grown in water-saving production systems. AbstractWater saving rice cultivation is indispensable in the wake of severe water shortage. Application of mulches can increase the water retention in water-saving rice; however, the effect of mulches on the growth and quality of rice are desired to be investigated. Hence, two years studies were conducted to evaluate the effect of plastic and straw mulch on crop growth, grain quality and recovery of fine rice. Water saving rice was grown under aerobic (AR) and alternate wetting and drying (AWD) conditions with application of plastic and straw mulch (5 t ha -1). Plots without mulch were maintained in both the water saving systems for comparison. Mulches significantly improved the growth of rice crop in terms of leaf area index, crop growth rate, leaf area duration and dry matter accumulation of rice compared with the no mulch. Similarly, the rice grain quality was also significantly improved by the mulch application. Mulch application increased the brown and white rice length, brown and white rice recovery percentage. The plastic mulch was more effective than straw mulch in improving the growth and grain quality of rice under AWD and AR. AWD was more effective in improving the rice grain quality compared with the AR. In crux, either of the plastic or straw mulch can be applied in fine grain basmati rice fields in order to improve the crop growth and grain quality. The effectiveness of plastic mulch surpasses the efficiency of straw mulch.

“…This is due to the fact that large proportion of the applied water is lost through deep percolation and seepage [2,[4][5][6]. Sizable efforts have been made to reduce deep percolation especially from rice fields including: alternate wetting and drying (AWD) [5,[7][8][9]; aerobic rice [10]; delayed application of continuous flooding [11] and puddling [6,12]. Berseem fodder (Trifolium alexandrinum L.) is a forage crop widely cultivated in northern India and the other parts of the world [13].…”
