Field experiments were conducted to study the influence of foliar nutrition on pod setting percentage, yield and economics of red gram (Cajanus cajan (L.)  under the irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112, Tamil Nadu, India in Kharif season of 2016-17. To study the effect of different nutrient sources the following treatments were imposed. The treatments include the foliar application of 2% DAP twice at flowering and 15 days thereafter first spray (T1), Foliar application of TNAU pulse wonder at 5 kg/ha at peak flowering (T2), Foliar application of 0.5% MAP twice at flowering and 15 days thereafter first spray (T3). Foliar application of CCC 200 ppm twice at flowering and 15 days thereafter (T4) and Control (water spray)(T5). Among the treatments, it was concluded that application of 0.5% mono ammonium phosphate (MAP) at flowering and 15 days after the first spray recorded the higher grain and stalk yield of 1522 and 6222 kg ha-1 in red gram respectively and also recorded a higher gross income of Rs. 91320, net income of Rs. 50520 and B: C ratio of 2.2. Further, the yield increase was 25% higher yield over control (water spray) and 12% higher over-application of CCC 200 ppm twice at flowering and 15 days after the first spray.

Field experiments were conducted to study the effect of establishment techniques on yield and economics of red gram [Cajanus cajan (L.)] under irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112,Tamil Nadu, India during Kharif season of 2013-14 and 2014-15 respectively in randomized block design with four replications. The treatments are line sowing/dibbling of seeds, sowing behind the country plough, sowing in polybag and transplanting at 25 and 40 DAS, sowing in portrays and transplanting in 25 and 40 DAS. The redgram variety LRG 41 was used for study. The results revealed that, dibbling of seeds in lines recorded higher grain yield of 2351 kg ha-1, net income of Rs.99495/- and B:C ratio of 3.39. Thus, dibbling of seeds in lines recorded 6% higher over sowing in poly bag and transplanting at 25 DAS and 27% higher yield over sowing behind the country plough. Considering yield and economics, line sowing seems to better option for the farmers followed by sowing in polybags and transplanted in 25 DAS. Under transplanted situation, transplanting of seedlings at 30 DAS was more suitable where the monsoon was delayed for 30 to 45 days under rainfed situation.

Field experiments were conducted at Coconut Research Station, Aliyarnagar during 2016 – 2019 to assess the performance of rice-based cropping sequences for water-scarce conditions of the Parambikulam Aliyar Project Command area of Tamil Nadu. Five cropping sequences viz., rice–sesame (T1), rice–groundnut (T2), rice– sunflower (T3), rice–castor (T4) and rice–black gram (T5) were experimented adopting Randomized Block Design with each sequence replicated four times. Results revealed that compared to the other non-legume sequences experimented, the contents of KMnO4-N and organic carbon in the post harvest soil, productivity of rice and economic efficiency were higher in rice–black gram followed by rice–groundnut sequence. Rice– castor sequence recorded the highest land utilization efficiency of 76.7 % and was the lowest in rice–black gram sequence (53.4 %). Rice equivalent yield was the highest on sequential cropping with sunflower (5755 kg ha-1) followed by groundnut (5028 kg ha-1). Production efficiency was the highest in rice– groundnut (47.5 kg ha-1 day-1) followed by rice–castor (42.5 kg ha-1 day- 1) systems. Net returns and benefit-cost ratio were higher in rice–sunflower and rice–black gram sequences followed by rice–groundnut and was the lowest in rice–sesame sequence. In terms of soil fertility, system productivity and economic returns, rice–sunflower, rice–black gram and rice–groundnut systems are highly remunerative for water-scarce conditions of Parambikulam Aliyar Command Area of Tamil Nadu.

Field experiments were conducted at the Agricultural Research Station, Aliyar Nagar, Tamil Nadu, India during summer 1994 and 1995 on groundnut, adopting a split plot design. Two irrigation regimes based on Irrigation Water/Cumulative Pan Evaporation (IW/CPE) ratios of 0.60 (I1) and 0.75 (I2) were allotted to the main plot. Twelve treatments involving combinations of organic manure with mineral fertilizer were assigned to the subplots. Irrigation scheduled at IW/CPE 0.75 led to higher plant height, number of branches plant –1, dry matter production and leaf area index, resulting in higher yield than IW/CPE 0.60. All the growth attributes and the yield increased in response to a higher level of mineral fertilizer application and organic manure application. The combined application of inorganic and organic manures significantly enhanced the growth attributes and yield of groundnut compared to the sole application of either of them.

The foliar nutrition of silicic acid is considered to be a novel approach in enhancing the performance of many crops worldwide. The present study aimed to assess if the foliar application of silicon (Si) could influence the performance of soybean varieties with distinct crop duration, MAUS-2 (long duration) and KBS-23 (short duration). Field experiments were conducted in two consecutive years (2016 and 2017) of varied rainfall with foliar application of silicic acid @ 2 and 4 mL L−1 for three and two sprays each. The results showed significant enhancement in the yield, seed quality (protein and oil content), and uptake of nutrients (N, P, K, Ca, Mg, S, and Si) by various parts viz., seed, husk, and haulm of both varieties with foliar nutrition of silicic acid. However, the short duration variety, KBS-23, responded well under low rainfall conditions (2016) with two sprays of foliar silicic acid @ 4 mL L−1 and MAUS-2 variety in the second season under higher rainfall (2017) with three sprays of foliar silicic acid @ 2 mL L−1, along with the recommended dose of fertilizer. This research revealed that the effectiveness of foliar silicic acid nutrition differs with the duration of the varieties, number of sprays given, and water availability in the soil during the cropping period.

SUMMARYField experiments were carried out at Ludhiana in Punjab during 1982 and 1983 on the effect of foliar application of water spray or naphthalene acetic acid (NAA) at 100 and 200 mg/1 of water on the growth and yield of rice when applied at tillering and before panicle emergence stages of late-transplanted paddy grown under four levels of nitrogen (0, 60, 90 and 120 kg/ha). Foliar spray of NAA significantly increased the grain yield of paddy as compared with water spray under low levels of nitrogen (0 and 60 kg/ha) owing to increases in the number of ear-bearing shoots per plant, number of filled grains per panicle and grain weight. Chlorophyll content of leaves, leaf area index and interception of photosynthetically active radiation by the crop canopy also increased with foliar spray of NAA and application of nitrogen. Paddy responded significantly up to 90 kg N/ha in terms of grain yield whereas straw yield increased significantly up to 120 kg N/ha. However, grain mass declined significantly with increase in nitrogen from 90 to 120 kg/ha.

SummaryField investigations conducted at Ludhiana (India) showed that the foliar application of 2-chloroethyltrimethyl-ammonium chloride (CCC) (50% a.i.) at 300,600 and 900 ml/ha about 5 weeks after planting did not depress plant height. The dose of 600 ml CCC/ha was most effective and increased seed yield by 1·31 and 0·74 t/ha over the control (water spray) in 1978–9 and 1979–80, respectively. The corresponding increases in total yield were 1·37 and 0·86 t/ha. However, in 1980–1 when CCC was applied 3 weeks after planting even the lower dose of 300 ml/ha depressed the plant height. Then the treatment of CCC increased significantly the number of tubers of seed size and seed yield by decreasing the ‘ware’ yield but did not influence the total yield. The yields of potatoes were not affected signifioantly by the application of N-dimethyl amino succinamic acid (B 9) and succinic acid (SA).In an experiment where the interaction of nitrogen and CCC was studied both factors not only increased the seed yield but also increased the total yield. However, there was no interaction between nitrogen and CCC.

Field experiments were conducted at the Agricultural Research Station, Bhavanisagar, Tamil Nadu, India during 1999 to 2000 in Inceptisols to evaluate boron fertilizers (borax, boric acid, Agribor) and to assess the effect of the mode and level of B application on the total B uptake and yield of sunflower and green gram. The experimental field was found to be deficient in available B (0.35 mg kg-1). Sunflower was raised as the main crop. Different B levels (0.5, 1.0, 1.5and 2.0 kg B ha-1)as soil application and two levels of foliar spray (0.2% and 0.3%) were compared with the control. The treatments were superimposed on the recommended dose of NPK. After harvestingthe main crop of sunflower, the residual effect of B was studied by raising green gram on the same field. The results revealed that the application of all the levels of B resulted in a significant increase in the B uptake and yield of sunflower as compared to the control. The highest yield was recorded for the soil application of B at a rate of 2.0 kg ha-1. The yield increase of sunflower was 3.6 to 15.8% and 7.2 to 18.9% over the control for seed and stalk, respectively. The green gram grain yield increased by 4.2 to 13.5% after the application of 1.0 and 2.0 kg B ha-1 to the main crop. No residual effect was observed for the lowest level of B application (0.5 kg ha-1). Agribor is equally as effective as borax in influencing the B nutrition of both the crops.

Field experiments were conducted during kharif 2013 and 2014 at Agricultural Research Station, Mugad, University of Agricultural Sciences (UAS), Dharwad (Karnataka), to determine the response of zinc applicationon on growth, zinc content and grain yield of rice genotypes and also studied correlation between yield and zinc content. The experiment was comprised of 20 genotypes and three treatments viz., T1: Control (no zinc); T2: Soil application of ZnSO4 (20 kg ha-1) T3– Foliar Spray of ZnSO4 @ 0.5% at 50% flowering, laid out in factorial randomized block design with two replications. The data revealed that application of ZnSO4 recorded significantly higher plant height (85.9 cm), leaf area (764.5 cm-2 plant-1), number of tillers (95.4 m-1), total dry weight (26.1 g plant-1), panicle weight(15.3 g plant-1), number of panicles (81.6 m-1) and grain yield(3966 kg ha-1) over the foliar application of Zn and control . However number of grains panicle-1 (97.8 panicle-1), test weight (23.7 g), shoot and seed zinc content (15.9 and 21.2 ppm, respectively) were increased with foliar application of Zn. Correlation studies classified the genotypes as high seed zinc content (> 21 ppm) and low seed zinc content genotypes ( less than 21 ppm). High and low seed zinc content genotypes showed negative correlation with yield and yield attributes. However, shoot zinc content was positively correlated with yield.
