The Cost

Aim: To compare the cost and return analysis of conventional maize cultivation with mechanization. Place of Study: A field experiment on maize crop cultivation by conventional and mechanization was conducted at Agricultural Research Station, Karimnagar during Kharif, 2019-20. Methodology: The cost concepts were used to estimate the cost of cultivation under conventional and Mechanization methods. The cost concepts viz., cost A1, cost A2 cost B1 cost B2 and cost C1, cost C2 and C3 were used in the present study. Results: The total costs of cultivation under conventional and mechanization methods were Rs.117794.78 and Rs.104137.92 per hectare respectively indicating 12 % saving with mechanization. Similarly gross returns were Rs. 146064.00 in conventional method against Rs.146988.00 in mechanized method.  Net returns recovered were 52% higher with mechanized method i.e Rs.42850.08 compared to conventional method Rs.28269.22. In the same way returns per rupee of investment in conventional method and mechanization were 1.23 and 1.41. Mechanization in cultivation also saves time, labour usage and reduces drudgery.

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.

SUMMARYMaize was grown al the Regional Agricultural Research Station, Hathazari, Bangladesh during 1988/89 and 1989/90 to study fodder yield, cob growth and grain yield together with the contribution of pre-silking stem reserves to grain. Population densities were 33300, 44400 and 66600 plants/ha. Plants were either detopped after silking and pollen shedding, keeping 0, 2 or 3 leaves above the cob, or were left entire.The results showed that the maize crop could successfully be detopped for fodder with little or no adverse effect on grain yield. Fodder yield increased with increased plant density and among the detopping treatments the highest fodder yield was obtained when the plants were detopped just above the cob. Cob growth followed a sigmoid pattern and the highest dry weight per cob was obtained from the lowest plant density and from entire plants. The number of cobs/m2 increased with increased plant density but detopping treatments did not give any significant difference in relation to densities. The number of grains/cob was highest with 33300 plants/ha but, among the detopping treatments, plants detopped just above the cob had the lowest number of grains/cob in both years. Weight of 1000-grain decreased with increasing plant density but it was increased by detopping plants just above the cob during 1988/89, although it was decreased in 1989/90. The highest apparent translocation of pre-silking reserves was obtained using densities of 44400 plants/ha but detopping treatments did not show any consistent effect, although the highest apparent translocation (20%) and harvest index (58%) were obtained from plants detopped just above the cob.

A field experiment was conducted at Main Agricultural Research Station, Dharwad during rainy season of 2015 and 2016 to study the effect of planting pattern and phosphorus management on production and profitability of intercropping system of mungbean and pigeonpea. The experiment was laid out in split plot design with three replications and eight treatments. Among them, four planting patterns [sole pigeonpea, mungbean + pigeonpea 1:3 (120 cm x 20 cm), mungbean + pigeonpea 1:2 (90 cm x 20 cm) and mungbean + pigeonpea 2:2 (90 cm x 20 cm)] were main plot treatments and two phosphorus levels (P2O5 @ 50 kg ha-1 and P2O5 @ 75 kg ha-1) were sub plot treatments. Based on pooled data the results revealed that, the significantly higher mungbean seed yield (424 kg ha-1) was recorded with application of 75 kg P2O5 as compared to 50 kg P2O5 ha-1. Whereas, in planting pattern, sole mungbean recorded significantly higher seed yield (757 kg ha-1) as compared to all other intercropping systems. Yield advantage indices and net returns were significantly higher in pigeonpea + mungbean (1:3) with 75 kg P2O5 ha-1 as compared to other treatments. This study indicated the need of fifty per cent higher dose of P2O5 for the pigeonpea and mungbean intercropping system (1:3) in northern transition zone of Karnataka.

Telangana State

Tornala village of Siddipet District (Previously part of Medak district) in Telangana State comes under low rainfall area with an average annual rainfall of 787.6 mm and experiences extreme seasonal variation in rainfall. A new Agricultural Research Station was established in 2014 to meet the agricultural needs of adjoining areas of Siddipet District. Maize is one of the principal crops of the Siddipet District grown in light soils under rain fed situation. Erratic behaviour of rainfall results in moisture stress of both kinds (excess and deficit) during maize growing season which is leading to frequent crop failures. Millets and pulses are gaining importance which can be grown very well under rainfed situation. To create awareness among the farmers about the importance of other drought tolerant crops suitable for the situation and also to promote drought resistant and short duration, nutritional rich pulse crops in place of maize was the primary objective in conducting this trial. Keeping the above in view, a field experiment was conducted to identify a suitable crop comparable/ alternative to maize with a view to reduce the risk of crop failure under rain fed conditions and to realize the nutritive value of millets. Nine crops viz. Bajra, Ragi, Korra, Maize, Green gram, Pigeon pea, Cotton, Castor Hybrid (PCH 111) and Castor variety (Kranthi) were evaluated for three years. Yields of all the crops were converted into maize equivalent yields and economics was worked out. Pooled means were worked out for yield as well as for economic returns. Results showed that higher maize equivalent yield was recorded in Pigeon pea (4354 kg ha-1) followed by Bajra (2804 kg ha-1), ragi (2604 kg ha-1), cotton (2344 kg ha-1) and green gram (2075 kg ha-1).  In terms of net returns pigeon pea recorded highest mean net returns (39080 Rs ha-1) followed by bajra (25553 Rs ha-1) and ragi (20614 Rs ha-1) whereas highest mean benefit cost ratio was with bajra (2.44) followed by pigeon pea (2.41) and ragi (2.05) compared to maize (2297 Rs ha-1 and 1.08 respectively). Hence, from the study it can be recommended that Bajra, Pigeon pea and Ragi can be grown in place of maize in low rain fall areas of Siddipet (Dt) under rain fed situation.

Strip Intercropping

Maintaining sustainable crop production on undulating, sloppy, and erodible soils in Shivalik foothills of North-west India is a challenging task. Intercropping is accepted as a highly sustainable system to reduce soil erosion and ensure sustainable production by making efficient use of resources. Field experiments were conducted in the rainy season (July to September) during 2015, 2016, and 2017 to evaluate the effect of land slopes and maize and cowpea strip-intercropping on productivity and resource conservation at the Regional Research Station, Ballowal Saunkhri located in the Shivalik foothills. During three years of experimentation, a total of 23–26 runoff events were observed in the maize crop grown in the rainy season. The results from this 3-year field study indicate that maize grain yield was significantly higher on a 1% slope and cowpea on a 2% slope. This accounted for significantly higher net returns (US$ 428 ha−1) with a benefit-cost (BC) ratio of 2.0 on a 1% slope. Runoff, soil, and nutrient losses were higher on a 3% slope as compared to 1% and 2% slopes. N, P, and K loss on a 3% slope were 3.80, 1.82, and 4.10 kg ha−1 higher, respectively than a 1% slope. The adoption of a strip-intercropping system with a 4.8 m maize strip width and 1.2 m cowpea strip width resulted in significantly higher maize equivalent yield than sole maize and other strip-intercropping systems. This system showed the highest land equivalent ratio value (1.24) indicating a 24% yield advantage over sole cropping systems of maize and cowpea, and fetched the highest net returns (US$ 530 ha−1) with a benefit-cost ratio (BC ratio) of 2.09. This system also reduced runoff and soil loss by 10.9% and 8.3%, respectively than sole maize crop. On all the land slopes, maize and cowpea strip-intercropping systems showed a significant reduction in N, P, K, and organic carbon loss as compared to sole maize. Thus, on sloping land, the maize and cowpea strip-intercropping system decreases surface runoff, soil, and nutrient loss, and increases yield and income of the farmers as compared to a sole maize crop.

In the present paper an attempt has been made to study the comparative economics of tomato cultivation under poly house and open field conditions in Karnal district, Haryana. Production and marketing constraints under poly house cultivation have also been identified. The primary data for the agriculture year 2013-14 were collected by personal interviews of the selected farmers with the help of a specially designed schedule. Simple statistical tool like Averages and percentages were used to compare, contrast and interpret the results properly. The overall findings of the study reveal that the cost of cultivation of tomato under poly houses was higher by Rs. 206816.90/acre as com-pared to open field conditions. At the same time, the net returns under poly houses were higher by Rs. 51097.54/acre. Farmers realized 53.71 % higher yield of tomato under poly house as compared to open field conditions. The gross return, returns over variable cost and net return were also higher by 106.94 %, 160.70 % and 48.70 %, respectively in case of poly house as compared to open field conditions. The results of the study also revealed that the tomato cultivation under poly houses has significantly contributed to the yield.
