A field experiment was conducted during kharif, 2015-16 at Agricultural College Farm, Raichur to ‘standardize fertigation technology for higher productivity of transplanted pigeonpea [Cajanus cajan (L.) Millsp.] on vertisols’ in the north-eastern dry zone of Karnataka. The results revealed higher number of pods (693.31) seed weight (12.16 g plant-1) stalk (5301 kg ha-1) and seed yields (3340 kg ha-1) with drip fertigation of recommended N and P2O5 (25:50 kg ha-1) in five splits using water soluble fertilizers (WSF) compared to other drip fertigation of water soluble and normal fertilizers at different levels of splits. Whereas significantly lower number of pods, seed weight and yield attributes were recorded with normal practice of soil application of commercial fertilizers without irrigation. Application of water soluable fertilizer (WSF) at 100 per cent RDF in 5 splits through drip method of irrigation also recorded higher gross returns (Rs.1,83,700 ha-1), net returns (Rs. 1,41,983 ha-1) and BC ratio (4.40) compared to all other treatments.

Field experiments were carried out during two seasons (August-February) of 2011-12 and 2012-13 at Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore, to study the effect of drip fertigation on productivity, water use and water use efficiency of pigeonpea (Cajanus cajan) cv. LRG 41. The treatments included three irrigation regimes (50 %, 75 %, 100 % computed water requirement of crop) and surface irrigation along with three fertilizer levels with water soluble fertilizer (WSF) and conventional fertilizers (CF). The treatments were laid out in Randomized Block Design with three replications. The results revealed that drip irrigation at 100 % WRc with fertigation at 125 % RDF through WSF registered significantly highest grain yield of 2812 and 2586 kg ha-1 during 2011-12 and 2012-13, respectively. Surface irrigation with conventional method of fertilizer application recorded lower water use efficiency of 3.70 and 3.38 kg ha-1 mm-1 whereas it was reverse with drip irrigation of 100 % WRc + 125 % RDF through WSF with a WUE of 6.97 kg ha-1 mm-1 during 2011-12 and during second season (2012-13), the highest WUE of 6.72 kg ha-1 mm-1 was recorded in drip irrigation at 50 % WRc along with fertigation at 125 % RDF through WSF. The increase in grain yield with drip irrigation at 100 % WRc + fertigation with 125 % RDF through WSF was mainly attributed by greater and consistent availability of soil moisture and nutrients which resulted in better crop growth, yield components and ultimately reflected on water use efficiency and yield of pigeonpea Cajanus cajan.

Nutritional Benefits

Aims: Sesame is grown in the country since antiquity. Sesame has high nutritional benefits and is utilized in numerous cooking styles everywhere globally. Sesame is called as the queen of oilseeds for the reason of its top notch polyunsaturated stable fats that limit oxidative rancidity and contains high oil content (up to 60%). Sesame is cultivated in summer in the North Telangana in turmeric and rice fallows. Low productivity in sesame is primarily due to rainfed planting on sub-marginal and marginal lands with poor management and low investment. To solve the upcoming challenges and in view of the improving yield and acquire higher returns, precised water management strategies need to be formulated. Hence the present investigation is proposed to study the effect of deficit and optimum irrigation at various growth stages on yield and economics of sesame crop grown in summer. Study Design: The experiment was laid out in a randomized complete block design. Methodology: A field experiment was conducted at Agricultural college, Polasa, Jagtial district during summer 2021 to study the effects of water deficit and optimal irrigation at various growth stages on yield and economics of summer sesame. The study is conducted with eight deficit and optimum irrigation treatments (T1 to T8) and replicated thrice. Results: The results of this experiment manifested that scheduling irrigation at vegetative, prebloom, flowering, capsule initiation and capsule filling stages (T8) registered highest yield attributes, yield and economic parametersviz., no of capsules plant-1 (45),capsule weight (0.32 g) and no of filled seeds capsule-1 (55), seed yield (1150 kg ha-1), stalk yield (1999 kg ha-1), gross returns (128499  ha-1), net returns (94391  ha-1) and benefit cost ratio (2.76).

A field experiment was conducted on sandy clay loam soils of Tirupati Campus of ANGR Agricultural University, Andhra Pradesh to optimise the sowing time and nutrient needs of rabi pigeonpea [Cajanus cajan (L.) Millsp.] for its sustained productivity and profitability. Three sowing times: II FN of September, I FN of October and II FN of October; three nutrient levels (N-P2O5-K2O kg ha-1): 10-40-0, 20-50-10 and 30-60-20 and two foliar treatments: NAA (25 ppm) and DAP (2%) at 60 DAS, 60 and 80 DAS were tested on LRG 41 pigeonpea cultivar in split-split plot design, replicated thrice. Earliest sown pigeonpea (II FN September) resulted in significantly higher seed yield (1700 kg ha-1) and net returns ( 32239) due to improvement in yield attributes like pod bearing branches plant-1, number of pods branch-1, number of seeds pod-1 and test weight. Highest nutrient level (30-60-20 NPK ha-1) produced significantly higher seed yield (1589 kg ha-1) and net returns (28448) due to improvement in yield attributes. Foliar application of NAA (25 ppm) and DAP (2%) applied at 60 and 80 DAS recorded significantly highest seed yield (1434 kg ha-1) and net returns (24111) due to its positive effect on pigeonpea yield attributes. Benefit:cost ratio was significantly high (2.71) due to earliest sowing, highest level of nutrient supply (2.46) and foliar application of NAA (25 ppm) and DAP (2%) applied at 60 and 80 DAS (2.26). Early sowings resulted in significantly higher seed yields at higher levels of nutrient supply. Foliar application of DAP (2%) at 60 and 80 DAS recorded significantly higher pigeonpea yield with early sowings. Early sown pigeonpea resulted in significantly higher seed yield at all levels of nutrient supply and foliar applications. Rabi redgram gave optimum yield and economic returns sown during II FN of September with 30-60-20 kg N, P2O5 and K2O ha-1 along with foliar spray of NAA (25 ppm) and DAP (2 per cent) twice at 60 and 80 DAS.

A field experiment was carried out during the kharif season of 2015 and 2016 to find out the best pigeonpea based intercropping system and planting pattern along with optimum dose of nutrients to intercrops. Present study revealed that yield attributes and yield of pigeonpea were not adversely affected by different planting patterns and nutrient levels applied to intercrop during both the years. Pigeonpea planted at 50 × 25 cm with maize fodder as intercrop recorded highest pigeonpea equivalent yield of 1840 and 1895 kg/ha during 2015 and 2016, respectively. Application of 100% recommended dose of nutrient to intercrop also significantly increased the pigeonpea equivalent yield (1629 and 1732 kg/ha) over 50% of recommended dose and control during both years. Pigeonpea (50 × 25 cm) + maize fodder fetched significantly higher net returns (Rs. 61191 and 68764/ha), B: C (1.7 and 2.0) and per day income (Rs. 453 and 509/ha/day) than other intercropping systems during both the years. Higher net returns (Rs. 50694 and 59568/ha) were recorded with 100% recommended dose of nutrient applied to intercrops as compared to net return with 50% of recommended dose (Rs. 43752 and 53344/ha) and control (Rs. 39163 and 46535/ha) during both the years. B: C and per day income were also recorded maximum with 100% of nutrients applied to intercrops during both the years.

Red gram [Cajanus cajan (L.) Millsp.] is a new introduction in the southern laterites of Kerala. The field experiment was laid out in factorial RBD to assess the performance of the short duration varieties of red gram, APK 1 and Vamban (Rg) 3 under two spacings (40 cm x 20 cm and 60 cm x 30 cm) and three nutrient levels (40:80:40, 30:60:30 and 20:40:20 kg NPK ha-1) in the Instructional Farm, College of Agriculture, Vellayani, Kerala during November 2018 to March 2019. Significant variations were recorded in growth and yield attributes and among the varieties, APK 1 was found to be superior with a seed yield of 997.78 kg ha-1. The closer spacing of 40 cm x 20 cm and the highest dose of 40:80:40 kg NPK ha-1 recorded the significantly highest seed yields of 1195.00 kg ha-1 and 1055.83 kg ha-1, respectively. The three factor interaction also revealed APK 1 and Vamban (Rg) 3 to record superior seed yields at the closer spacing and higher nutrient dose. The short stature, lower branching tendency, early flowering nature and higher yields in APK 1, proved its suitability for cultivation in southern laterites of Kerala and the agronomic package would involve sowing seeds at a spacing of 40 cm x 20 cm with an NPK dose of 40:80:40 kg ha-1.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

On sandy soil near Esperance, W.A., prevention of burr burial compared with covering developing burrs with sand drastically reduced the seed production of three subspp. of Trifolium subterraneum (brachycalycinum, subterraneum and yanninicum) and of T. israeliticum by reducing burr production and seed weight. However, T. globosum produced similar amounts of seed from unburied and buried burrs. On sandy soil at Shenton Park, Perth, W.A., prevention of burr burial also reduced seed production of T. subterraneum subspp. brachycalycinum and subterraneum, this being due to fewer burrs, fewer seeds per burr and lighter seed. For subsp. brachycalycinum, seed yields were two to five times greater from burrs which developed within loose gravel than from those developed over sand (in which fewer burrs were able to bury) as a result of increased production of burrs, more seeds per burr and heavier seed. However, for subsp. subterraneum seed yields were similar from burrs whether developed over gravel or sand.
