Background: Redgram a predominant dryland crop is vulnerable to the whims of rainfall at initial stages of crop growth. Moreover, the wider spacing promotes transplanting over conventional method but, appropriate nursery technique is yet to be standardised to prevent root coiling which leads to poor plant stand under main field conditions. Methods: A field experiment was conducted during 2020-21 at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai to identify suitable nursery techniques for raising redgram seedlings. Redgram was raised in poly bag, 98 cone protray, 50 cone protray and high density poly ethylene (HDPE) woven fabric mat for 20 and 30 days before transplanting. The experiment was laid out in randomized block design replicated thrice. Result: The results revealed that, raising redgram seedlings in HDPE woven fabric mat and transplanting at 20 DAS resulted in lesser root length, root volume but with lesser root coiling coefficient which is highly favourable. Moreover, after being transplanted the seedlings recorded higher plant height, leaf area index with increased photosynthetic activity, respiration andchlorophyll content. Similarly, higher yield and benefit cost ratio was attained over the conventional line sowing. Therefore, raising red gram seedlings in HDPE woven fabric mat can be considered as a cost-effective technology to attain higher yields and with the possibility to gap fill under poor seedling establishment without differential harvest maturity under the dry land tracts of southern Tamil Nadu, India.

“…Even still, the authors noted that the higher root-shoot ratio of D40 seedlings compared with polybag seedlings was potentially more favorable for dry outplanting conditions. In another study, researchers found higher physiological function of Hevea seedlings grown in polybags compared with Rootrainers™ and attributed this to "root confinement" [50]. This finding indicates that seedlings were grown too long in the Rootrainers™ and the results were due to a mismatch between the growing schedule and the container size.…”

An important strategy for meeting global landscape restoration goals is nursery production of high-quality seedlings. Growing seedlings with attributes that promote post-planting survival and growth can be dramatically influenced by the nursery container system. In many countries, nurseries produce seedlings in polybags filled with excavated soil. These seedlings often develop deformed roots with limited fibrosity which can lead to poor survival and growth after outplanting. Polybags are initially inexpensive but using these single-use plastic containers accrues expenses that are often untracked. Comparisons among nursery production systems must account for factors such as container longevity, labor efficiency, and seedling field performance. A more holistic approach to account for environmental, economic, social, logistic, and cultural elements in the cost–benefit equation that influences nursery production systems is needed. Converting to a modern container system requires concomitant adjustments in nursery scheduling and culturing matched to the new stock type. Doing so provides an opportunity to align nursery production techniques and resulting seedling attributes with anticipated field conditions. This article describes and discusses the advantages and disadvantages of nursery production systems and provides recommendations and case studies to aid nurseries in improving seedling quality toward meeting restoration goals in a cost-effective and timely manner.

“…According to some studies, drought reduced the growth and yield of the rubber tree [3,25,26]. Only one drought-tolerant rubber clone, RRIM 600, has been identified and is being used in dry areas of Thailand and India [27][28][29][30].…”

It is predicted that drought will be more frequent and sustained in the future, which may affect the decline of rubber tree production. Therefore, it is critical to research some of the variables related to the drought-resistance mechanism of the rubber tree. As a result, it can be used to guide the selection of new rubber drought-resistance clones. The goal of this study was to identify drought-resistance mechanisms in rubber clones from the high drought factor index (DFI) group using ecophysiological and biochemical variables. The treatments consist of two factors, namely water deficit and contrasting clones based on the DFI variable. The first factor consisted of three levels, namely normal (fraction of transpirable soil water (FTSW) > 0.75), severe water deficit (0.1 < FTSW < 0.20), and recovery condition (FTSW > 0.75 after rewatering). The second factor consisted of seven clones, namely clones G239, GT1 (low DFI), G127, SP 217, PB 260 (moderate DFI), as well as G206 and RRIM 600 (high DFI). RRIM 600 had the highest DFI among the other clones as a drought-tolerance mechanism characteristic. Furthermore, clones RRIM 600, GT1, and G127 had lower stomatal conductance and transpiration rate than drought-sensitive clone PB 260. As a result, as drought avoidance mechanisms, clones RRIM 600, GT1, and G127 consume less water than clone PB 260. These findings indicated that clone RRIM 600 was a drought-resistant clone with drought tolerance and avoidance mechanisms.
