A field experiment was conducted at Tamil Nadu Rice Research Institute, Aduthurai, Tamil Nadu during Summer, 2013 and 2014 to study the response of blackgram varieties to different levels of irrigation through applied sprinkler system. Four levels of irrigation I1 - 50 per cent pan evaporation through sprinkler irrigation, I2 - 75 per cent pan evaporation through sprinkler irrigation, I3 - 100 per cent pan evaporation through sprinkler irrigation and I4 - Surface irrigation in main plot and three blackgram varieties viz., ADT 5, PBG 4 and VBN BG 6 were evaluated in split plot design with three replications. Sprinkler irrigation at 100% pan evaporation in variety ADT 5 gave significantly better growth and yield attributes and higher grain yield of 1217 kg/ha which was at par with surface irrigation method in ADT 5 variety (1184 kg/ha). Surface irrigation method utilized higher amount of irrigation water of 428.1 mm and 413.6 mm, whereas, sprinkler irrigation at 100% pan evaporation utilized minimum amount of irrigation water of 329.2 mm and 308.7 mm during summer 2013 and 2014, respectively. Water saving under sprinkler irrigation at 100% pan evaporation was 23.1% and 25.4% as compared to surface irrigation method during summer 2013 and 2014, respectively.

Background: Investigations were carried out during Rabi, 2016 and Summer, 2017 at farmer’s field in Kodukkanpalayam village of Cuddalore District, Tamil Nadu to evaluate the direct effects of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), crop residues, farmyard manure with 50% inorganic sources, with and without Rhizobia on various traits of groundnut. There were twelve treatments in randomized block design (RBD) with three replications. Results revealed that the growth and yield components of groundnut viz., plant height, DMP and LAI at flowering stage, number of pods per plant, hundred kernel weight, pod yield and kernel yield were greatly influenced by the treatments. Methods: Combination of Pressmud @ 12.5 t ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T7) recorded the highest and followed by the application of distillery spentwash @ 100 m3 ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T8). Similar trend of results was recorded in summer, 2017 also. This might be due to the increase in the availability of nutrients, which increased the growth and yield attributes of groundnut in both the seasons. Also, use of agro industrial wastes and biofertilizers in any cropping sequence minimize the cost of inorganic fertilizers, thereby act as a boom to farmers by making the waste into wealth and maintain the soil health and fertility. Result: The study revealed the scope of utilization of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), organic sources (crop residues and FYM) and biofertilizer (Rhizobia) in Agriculture.

A field experiment was conducted in sandy loam soils of eastern farm, Agricultural Engineering College and Research Institute, Kumulur, Tamil Nadu, India to study the effect of silicon on yield and uptake of rice (var. BPT 5204) during Kharif season of 2010-11 by taking the treatment combinations based on graded levels of Fly Ash (FA), Silicate Solubilizing Bacteria (SSB) and Farm Yard Manure (FYM) at fixed fertilizer schedule. The experimental soil (0-15 cm) had pH 7.22; organic C 1.4 %; available Si 66.0 mg kg-1; available N 266.0 kgha-1; available P 14.42 kgha-1 and available K 107.50 kgha-1. The results of graded levels of FA show that all the growth and yield attributes were significantly influenced by silicon uptake. The mean silicon uptake at panicle initiation, straw and grain at harvest varied from 53.8 - 98.7, 105.5 - 197.2 and 21.4- 62.3 kgha-1 respectively, in rice. Number of filled grains per panicle and grain yield displayed conspicuous relationships with content of Si in grains. The highest mean grain yield of 3622 kg ha-1 was recorded by the addition of SSB+FYM followed by FYM (3530 kg ha-1), SSB (3310 kg ha-1) and control (3240 kg ha-1). The combined application of 25 t ha-1 FA with SSB+FYM was recorded the highest grain yield of 3710 kg ha-1 which was 16.3 per cent moreover yield of control. The results further show that 25 t ha-1 FA and SSB+FYM have been proved to be superior treatments for best management of silicon in coastal loamy sand soils under irrigated rice ecosystem.

Biochar is considered as a possible and potential tool for soil fertility improvement, climate change mitigation and long term sink for atmospheric carbon dioxide. Soil application of biochar enhances the soil properties indirectly. A field experiment was conducted to evaluate the influence of organic manures viz., Farm Yard Manure (FYM), Vermicompost, Biochar, Biochar composite on soil properties, growth and yield of bhendi, Abelmoschus esculentus in Somayyanur soil series of Madurai district, Tamil Nadu. The experiment was laid out in randomized block design (RBD) with eleven treatments and three replications during the summer season (March – June) 2021 with the inclusion of inorganic fertilizers based on soil test crop response (STCR) based recommendation. Application of biochar composite (5 t ha-1) along with STCR based NPK (75% STCR) increased the total carbon content in soil by 0.538 %. This, in turn, increased the available nitrogen status to 295 and 244 Kg ha-1 at 40 and 70 DAS, respectively. Similarly, the available phosphorous (22.4, 19.3 Kg ha-1) and potassium (344.70, 323.70 Kg ha-1) status also showed a considerable increase with the same treatment. The yield attributes of bhendi viz., fruit length, girth, weight, dry matter production and yield recorded maximum values of 15.23 cm, 6.93 cm, 21.56 g, 11.9 t ha-1 and 25.20 t ha-1 with the combined application of biochar composite and NPK. The findings revealed that 25 % STCR based NPK could be reduced with the application of 5 t ha-1 of biochar composite, which is economically an option besides promoting soil health.

Plant nutrients and soil moisture are considered some of the most important factors affecting physiological characters and grain yield of maize. Therefore, a field experiment was conducted at UBKV, Cooch Behar, West Bengal during 2013 and 2014 to study the effects of moisture conservation and nutrient management practices on growth and yield of maize (Zea mays L.). The experiment was laid out in a split –plot design with three replications. Four levels of moisture conservation practices M0: without irrigation and without mulch, M1: irrigation as and when required, M2: dry weed biomass mulch @5.0t ha-1 M3: FYM mulch @ 5.0 t ha-1 were assigned to main plots and four levels of nutrient management N1: 100% RDF 80:40:40 kg ha-1 of N:P2O5: K2O N2:100% RDF + phosphate solubilising bacteria (PSB) + Azotobacter N3:75% RDF+ PSB + Azotobacter + vermicompost (VC) @ 5.0 t ha-1 and N4:50% RDF + PSB + Azotobacter + 50% vermicompost @ 2.5t ha-1 for sub plot. Among the moisture conservation practices, application of irrigation recorded the highest growth, yield attributes, yield and harvest index followed by FYM mulch and dry weed bio-mass mulch. Similarly, N, P and K uptake of maize was recorded highest under irrigation followed by FYM mulch; dry weed bio mass mulch and lowest N, P and K uptake were recorded under without irrigation and mulch. Among the nutrient management practices the highest growth, yield attributes, yield, harvest index and N, P & K uptake were recorded under 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 followed by 100% RDF + PSB+ Azotobacter & 100% RDF and lowest were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1 . Likewise, maximum benefits were recorded under 75% RDF + PSB+ Azotobacter + vermicompost @ 5.0 t ha-1 and lowest net return and return per rupee invested were recorded under 50% RDF + PSB + Azotobacter + 50% vermicompost 2.5 t ha-1. From this study, maize grown with irrigation and supplied with 75% RDF + PSB + Azotobacter + vermicompost @ 5.0 t ha-1 is found the best for obtaining overall gain on a sustainable basis.

Main Factor

Irrigation with saline water adversely affects rice production and degrades land productivity in the coastal zones of many countries in the world. This study aimed at developing a suitable irrigation management practice to reduce the harmful effects of salinity on rice production under saline water irrigation. An experiment in raise-bed lysimeters was set in a split-split-plot design with irrigation–drainage practice as the main factor, irrigation water salinity as the sub-factor and rice variety as sub-sub factor; main factor and sub-factor comprised four treatments and the sub-sub factor comprised three treatments, each with three replications. The treatments of the main factor were – T1: 2-5 cm continuous ponding, T2: continuous saturation, T3: changing irrigation water after 3 days of application by maintaining 2-5 cm ponding depth, and T4: changing irrigation water after 5 days of application by maintaining 2-5 cm ponding depth. The sub-factor comprised – SL1: fresh water as control, SL2: saline water of 6 dS m-1, SL3: saline water of 9 dS m-1, and SL4: saline water of 12 dS m-1. The sub-sub factor comprised three salt-tolerant rice varieties V1: Binadhan-8, V2: Binadhan-10, and V3: BRRI dhan-47. The irrigation–drainage practices T2 and T3 provided significantly (p£0.05) improved growth and yield attributes of the rice varieties under salinity water level SL3 and SL4 compared to T1 and T4 treatments. The treatment T3 maintained least exposure of the crop to high degree of salinity and produced satisfactory plant attributes by inhibiting the detrimental effects of salinity. Therefore, T3 is suggested for adoption in practical fields when provision for removing high saline water from the rice fields can be arranged.

A field experiment was conducted to assess the suitability of saline water for irrigation, and to know the irrigation water requirement of groundnut-wheat cropping sequence in hyper-arid region of Rajasthan. In this split-plot experiment, the main plots had four levels of irrigation water salinity (ECiw0.25 (Best available water, BAW), 4, 8 and 12dS.m-1); and the sub-plots had combinations of two treatments on drip lateral spacing of 0.60 m and 0.90 m with 0.30 m emitter spacing, and three levels of irrigation water application (0.6, 0.8 and 1.0 times of pan evaporation (PE)). The highest biological yield (grain + straw) of groundnut and wheat recorded in BAW was statistically at par with irrigation water salinity level of 4 dS.m-1. Higher irrigation water salinity levels (8 and 12 dS.m-1) and placement of laterals at 0.90 m led to significant reduction in biological yield. In monetary terms, use of BAW resulted in highest B:C ratio of 1.73 for groundnut-wheat cropping sequence, while ECiw 4 dS.m-1 showed B:C ratio of 1.70. Highest crop yields, gross return and B:C ratio were observed under 0.60 m lateral spacing and irrigation application at 1.0 PE. Interaction effect of salinity of irrigation water and lateral spacing on yield and yield attributes was significant for both crops. Study demonstrated that the salinity limit of 4 dS.m-1 can be considered as threshold irrigation water salinity for drip irrigated groundnut and wheat crops in hyper-arid region of Rajasthan

The experiment comprising of four levels of phosphorus, i.e., 0, 20, 40 and 60 kg ha-1 and four levels of zinc, i.e., 0, 5, 10 and 15 kg ha-1 was conducted to investigate the interaction effect of phosphorus and zinc fertilization on yield and yield attributes of green gram [Vigna radiata (L.) Wilczek] cv. SML-668. The treatments were laid out in Randomized Block Design (Factorial) with three replications. The results revealed that plant height, number of pods plant-1, 1000 seed weight, seed and stover yield were increased significantly up to 60 kg ha-1 phosphorus and 10 kg ha-1 zinc treatment levels. Further increase in zinc levels found to decrease the yield and yield attributing traits, indicating antagonistic effect of phosphorus and zinc on each other. The highest plant height, number of pods plant-1, 1000 seed weight, seed and stover yield (at 60 kg P ha-1 and 10 kg Zn ha-1 treatment level) were 48.70 cm, 27.15, 32.70 g, 957.25 and 2398.30 kg ha-1, respectively. Thus, interaction of phosphorus and zinc was significant for all the growth and yield attributing parameters.
