A field experiment was conducted at Karaikal “the tail end of Cauvery Delta Zone” during Navarai season, 2017 (spring) to identify the optimum dates of sowing and seed priming practices on dry matter production (DMP), yield and yield attributes under aerobic rice condition. The treatment variables were replicated thrice and further evaluated in factorial concept of RBD. The treatments consisted of three dates of sowing by weekly interval (started from Feb. 6, 2017) and five seed priming practices viz., water, 1% KCl, 2% moringa leaf extract, 1% pungam leaf extract and 5% cow dung slurry. Considering the seed priming practices, dry matter production, yield and yield attributes of aerobic rice were higher in seed primed with 2% moringa leaf extract which ultimately produced higher grain yield (2256 kg ha-1) followed by the seeds primed with 5% cow dung slurry (1945.1 kg ha-1) and 1% pungam leaf extract (1912.3 kg ha-1), respectively. From the study, it has proved that seed priming @ 2% moringa leaf extract provides higher productivity of aerobic rice during Navarai season at Karaikal.

Aerobic rice is a new way of cultivating rice that requires less water than lowland rice. A field experiment was conducted during the kharif season of 2015 to evaluate the effects of nutrient management with Biofertilizers on growth and yield attributes, yield, nutrient uptake and economics different rice cultivars. The experiment was laid out split plot design with four replications. Main plot treatments consisted of two cultivars viz., whereas, sub plot treatments comprised of nutrient management practices namely, N1-125% RDF, N2-125% RDF + Biofertilizers, N3 -100% RDF, N4 -100% RDF + Biofertilizers, N5-75% RDF, N6-75% RDF + Biofertilizers. The source of biofertiliser was a combination of Azospirillum, Phosphorus Solubilizing Bacteria and Potassium Solubilizer applied @ 5 kg/ha-1. Crop dry matter production (2582.3 g/m2), root dry matter production (910.1 g/m2), tillers/m2 (566), leaf area index (4.54), panicles/m2 (535), panicle length (23.81), panicle weight (4.56) and test weight (25.3) was higher in PA 6444 compared to DRR Dhan 44. Higher uptake of nutrients was also observed in PA 6444. Rice fertilized with 125% RDF + Biofertilizers (N2) produced higher crop (2901.6 g/m2) and root dry matter production (1028.1 g/m2), tillers/m2 (561) and leaf area index (5.19). This treatment also recorded higher yield attributes and grain yield (3.55 t/ha). With respect to nutrient uptake, application of 125% RDF + Biofertilizers (N2) recorded      higher N, P and K uptake by grain and straw and higher profitability (1.57) than other nutrient combinations.

An experiment was conducted during <italic>rabi</italic> season of 2010-12 to study the response of chickpea varieties to nutrients levels on a calcareous vertisols. The experiment comprised of four varieties i.e., NBeG-3, NBeG-28, JG-11 and KAK-2 and with four nitrogen levels i.e., 0, 20, 30 and 40 kg/ha laid out in factorial randomized block design with three replications. Among the varieties significantly higher dry matter production at harvest was recorded with JG-11 while it was lowest with KAK-2. More number of pods per plant and seed yield were recorded with JG-11 followed by NBeG-3 and NBeG-28, while lowest with KAK-2. Interaction effect among the different varieties and nitrogen levels was non significant with yield attributes. Significantly higher seed yield was recorded with JG-11 @ 40 kg of N/ha but was at par with N @ 20 and 30 kg /ha, followed by NBeG-3 and NBeG-28.

A field investigation was carried out during Rabi season (Pishanam rice) of 2012-2013 at wetland of Central Farm, Agricultural College and Research Institute, TNAU, Killikulam, to study the effect of integrated nutrient management practices on dry matter production, yield and NPK uptake of transplanted rice. The treatments were laid out in a Randomized Block Design and replicated thrice using the rice variety ADT(R) 45. Among the different integrated nutrient management practices, application of GLM @ 6.25 t ha-1 + Azophosmet + 100 % NPK registered significantly the highest (P<0.01) dry matter production at all the stages (Active tillering; 1690, flowering; 9100 and harvest;14490 kg ha-1). The grain yield was increased, when GLM was integrated with 100 % NPK application (6030 kg ha-1). The grain yield was further increased, when Azophosmet was applied through seed and soil application along with GLM and 100 % NPK (6617 kg ha-1). However, it was on par with application of FYM + Azophosmet + 100 % NPK. The same trend was noticed in straw yield also. The uptake of N, P and K nutrients by rice crop at har-vest stages (95.6, 37.7 and 118 kg ha-1) of crop growth was remarkably increased by the application of GLM + Azophosmet + 100 % NPK. Among the various nutrient management practices, application of GLM + Azophosmet + 100 % NPK registered superior growth indicators due to the effective utilization of various nutrients and subsequent accumulation of more assimilates which inturn led to improved vegetative growth and higher yield of transplanted rice.

Abstract Background The productivity of pulse crop is low due to cultivation on agriculturally marginal and sub marginal lands under poor management. So, it needs earnest attention in adaption of desirable production technologies to exploit the yield potential of the pulses and it can be possible by application of fertilizers, nipping and foliar application of nutrients.In this view, aresearch was conducted to studyyield maximization, agronomic efficiency and nutrient uptake pattern with nipping and nutrient management practices in irrigated pigeonpea.Methods Field experiment was conducted at farmer’s field, Palacode, Palacode Taluk, Dharmapuri District.The pigeonpea seeds were sown by adapting a spacing of 45 × 30 cm. Entire dose of N, P2O5 and K2O (25: 50: 25 kg)were applied basally and the foliar spraying of 0.5 per cent Micronutrient mixture was done as per treatment schedule on 30th& 45th days after sowing using Knapsack Sprayer with the spray fluid of 500 lit. ha-1.Results The results revealed that the application of T9 (125% RDF + Nipping + Micronutrient) recorded significantly higher dry matter production, yield and nutrient uptake.The least values were recorded under the treatment T1 (Control).
