4. Achievements, Recommendations and Findings:

1993-2000

1. Survey of salt affected soils and quality of irrigation water:

Soil salinity and poor quality of irrigation water have been found to be two most important constraints affecting the optimum production of crops. For assessing type of salt affected soils and quality of irrigation water 819 representative soil samples and 181 irrigation water samples have been analysed, 66.1% soil samples were found to be salt affected which were classified into following categories:

Saline- 43.5%; Saline sodic- 9.8 % and Sodic soils- 12.8%. This study is useful in salt affected soils. Gypsum requirement was worked out for saline sodic and sodic soils.

80.2% irrigation water was of poor quality which were classified as follow:-

Saline- 49.2%; Saline Sodic- 26.7% and Sodic 4.3%. 8.3% of irrigation water had high RSC ( > 5 me/l) values.

Suitable technology for managing poor quality irrigation water is being worked out.

Soil Fertility: Judicious use of fertilizers based on soil testing is one of the most important factor governing productivity of soils. Analysis of 819 soil samples for available N,P and K revealed that 85.8% soils were low in available N whereas 14.2% medium in it. Available P was low in 19.0%, medium in 39.7%  and high in 41.3%. Available K₂O was high in 84.5% of the samples whereas 15.5% contained medium range.

Available Micronutrient:         117 representative soil samples were analyzed for DTPA extractable 10.2% samples were deficient (< 0.60 ppm) in available zinc, 38.4% marginal (0.60-1.20 ppm) and remaining 51.8% sufficient in it. Deficiency has been further confirmed by the soil test crop response studies with wheat as a test crop as reported in the section on nutrient management in saline soils.

2. Verification of most suitable varieties of crops for the zone IIIb.

S.No.	Crop	Varieties
(i)	Mustard	RH 819, BIO 902, RH 30, Pusa Bold, RN 393, Laxmi
(ii)	Wheat	Raj 1482,CPAN 3004, Raj 3765, Raj 3777, Lok 1
(iii)	Barley	RD 2503, RD 2552, RD 2035
(iv)	Gram	RSG 44, KPG 59, RSG 888, CSJD 884
(v)	Lentil	K 75, Sehore 74-7, L 4076
(vi)	Clusterbean	RGC 936, RGC 986, RGC 1003

3. For mustard crop grown under unirrigated heavy texture soils application of 40 Kg N and 40 Kg S ha^-1 (through gypsum) was found optimum.

4. For mustard crop 45 cm. spacing between row to row has been found optimum under tank bed, heavy texture soils.

5. The spray of Thio urea @ 0.1% at 60 DAS increases the seed yield of mustard by 10 to 12% over control. In this way an additional return of about Rs.3024 ha^-1 can be fetched.

6. The application of Zinc Sulphate @ 20 Kg ha^-1 significantly increases the grain yield of lentil.

7.  Mixed cropping of lentil + mustard (12:2 or 6:1 rows) was found superior over lentil alone or over farmers practice (seed mixture).

8. Research conducted to find out the response of sulphur under tank bed micro farming situation revealed that increasing levels of sulphur, significantly increased the grain yield of cluster bean upto 40 kg S/ ha^-1, beyond which no further response was observed.

9. Wheat (Raj 1482) irrigated with saline sodic water (EC : 10.4 dsm^-1 and SAR : 10.6 ) responded significantly to N, P and Zn. Combined application of 120, 60 and 40 Kg/ ha of N, P₂O₅ and ZnSO₄, respectively increase the grained yield of wheat by 14.0 % over control (90Kg N + 40Kg P₂O₅  ). It suggests that under saline conditions N, P and Zn requirement is higher as compared to non saline conditions.

10. The optimum seed rate for Gram semi bold varieties was found 80 Kg ha^-1 and for small seeded varieties was found 60 Kg ha^-1.

Application of starch polymer @ 10 Kg/ha (seed mixed) gave better results during kh. 2002 (drought seasons).

The result showed that 1000 ppm Thiourea spray at 50% flowering (75 DAS) produced the maximum seed yield with mean yield of 1108 kg ha^-1. It is quite evident from the table that spray of Thiourea found significantly superior over control & all other agrochemicals, but there was no significant effect of spray stage and dose too, but the highest net additional return of Rs. 2955 ha^-1 fetched with the 1000ppm of TU at 50% flowering (75 DAS) closely followed by 1000 ppm spray of TU at pre flowering (60 DAS) by giving that additional return of Rs.2845 ha^-1.

Highest mean yield of methi grain (22.26 q/ha) was obtained at one cutting at 45 DAS and 10 Kg nitrogen as top dressing at the time of cutting. This yield is significantly higher than the treatment combination with two cutting, however non significant to no cutting and one cutting at 30 DAS in all the three consecutive years i.e. 2004-05, 2005-06 and 2006-07. The mean minimum yield was obtained at two cutting at 45 DAS and 75 DAS (14.69/ha). In irrigated heavy textured tank bed micro farming situation of zone III b, the fenugreek crop shows luxurious vegetative growth causes lodging the crop resulting in reduction in yield. However pruning imparts harmful effect to the overall growth of plant but in these conditions, one pruning at 45 DAS checks the overgrowth of the crop and top dressing of nitrogen @10 Kg /ha at the time of pruning help in recouping the vegetative growth , hence gave maximum production at this treatment. On the other hand two pruning proved hazardous to growth of plant, consequently drastic reduction in yield occurred.

Tomato seedlings raised in polythene bags of 250 g capacity produced significantly high mean fruit yield (340.33q /ha), over all the other treatments giving highest net return Rs. 168231.00 per ha.( B:C ratio 1: 2.40). It is about 32.5% more fruit yield over raised seed bed (256.67 q/ha). Nursery raised in lines and 100g cups also proved better over broadcasting method. In traditional method of nursery raising seedlings are grown densely, where proper nutrition, sunlight and space is not available to plant growth, hence weak, non-uniform and unhealthy seedlings takes place, whereas 250g  polythene bags seedlings get proper sunlight, nutrition and space for proper growth of the seedlings. Consequently, healthy plants comes out and there is no transplanting shock occur during transplanting, if seedlings are grown individually in polythene bags, which is unavoidable in the seedlings grown in seedbed. It also reflects in fruit yield of tomato, which is more in those plants grown in polythene bags.
