. The experiment was conducted during the 2019-2020 growing season at the Agricultural College and Research Institute in Thanjavur, India. The effect of plant growth regulators and micronutrients for improving seed germination of rice offsprings ( Oryza sativa L.) were investigated. The experiment followed a randomized block design, consisting of twelve treatments and three replications. The predominant rice variety cultivated was ADT 46, known for its long, slender grain but poor germination characteristics. The treatments involved foliar spraying at 60 and 90 days after transplanting (DAT), before panicle emergence. The highest recorded plant height was achieved with the application of Cytokinin @ 50 ppm + ZnSO 4 @ 0.5% at 60 and 90 DAT during the main crop growth phase. Interestingly, for all other growth and yield parameters, the most favorable results were observed with the application of Naphthalene acetic acid (NAA) @ 40 ppm + ZnSO 4 @ 0.5%. Notably, this treatment significantly boosted the germination percentage to 98.38% when tested three months after storage, marking a 13.00% increase compared to the control. It also demonstrated the highest seedling vigor indexes I (2996) and II (792). Hence, it is recommended that the application of NAA @ 40 ppm + ZnSO 4 @ 0.5% foliar sprays at 60 and 90 DAT to address germination issues in rice and achieve higher yield and profit for farmers.

Abstract Though plastic film mulch technology has been used widely to increase crop productivity in dryland farming, the economical as well as environmental costs associated with plastic mulches is the major factor limiting the wider adoption of this technology. With the objective of reducing the cost of plastic films by growing more than one crop prior to its disposal, experiments were conducted over 3 years (2012–15) during South West monsoon (SWM) and North East monsoon season (NEM) with four treatments, T1- Transparent plastic mulch maintained for two crops (TPM I), T2- Transparent plastic mulch laid new for each crop(TPM II), T3- Non mulched beds maintained for two crops (NM I) and T4 – Non mulched new beds for each crop (NM II). The crops sown were Blackgram (Vigna mungo) in the first season (SWM) and Groundnut (Arachis hypogaea) in the second season (NEM). Results indicated that soil temperatures appeared highest under transparent mulch in different phenophases of both blackgram and groundnut from sowing to harvest. The mulch film was physically sound even upto the harvest of the second crop (Groundnut) in each year of the study. The light transmission through the transparent mulch maintained for two seasons (TPM I) was also not relatively reduced which has been evidently seen in the soil temperature observed. Both air Degree −Days (DD) and soil Degree –Days (DD) varied between mulched and non- mulched treatments at all the phenophases of observation. The physical properties such as rate of water loss/day, hydraulic conductivity, soil bulk density and percentage of pore space of the soil were also influenced by transparent plastic mulch. Transparent mulch, either newly laid or maintained for two seasons, had an impact on yields of both blackgram and groundnut. As a result the net return was highest with the transparent plastic mulch maintained for both the crops. These results suggest that double-cropping of transparent plastic mulches can be done without loss of crop yield and provide significant savings in cost of land preparation, materials and laying cost, labour and disposal costs.
